Atrazine Lawsuit Attorney
PRACTICE AREAS
An atrazine lawsuit is a personal injury claim against Syngenta and other herbicide companies that manufacture atrazine. These claims are brought by people diagnosed with non-Hodgkin’s lymphoma or other type of cancer after being exposed to atrazine.
In November 2025, the World Health Organization’s cancer agency classified atrazine as probably carcinogenic to humans. Claims are being filed individually nationwide. There is no MDL yet.
Reich & Binstock is reviewing atrazine lawsuit claims nationwide from our Houston office. If you applied atrazine or lived where it was used heavily and later received a non-Hodgkin’s lymphoma diagnosis, an atrazine cancer lawsuit may be available to you. Our law firm offers free consultations, and clients don’t pay unless we recover full and fair compensation.
Our law firm handles atrazine cases on contingency. You don't owe anything unless you get paid.

Sources: The Lancet Oncology; IARC Meeting 140.
Most atrazine lawsuit filings trace to November 2025, when the International Agency for Research on Cancer classified the herbicides atrazine and alachlor as Group 2A, probably carcinogenic to humans. IARC’s Group 2A classification of atrazine rested on limited human evidence, sufficient laboratory and animal studies, and strong mechanistic evidence. This was reported in The Lancet Oncology.
The full literature outlining the experimental animal studies and other scientific evidence isn’t expected until 2027. This means the record supporting atrazine lawsuits is still being formally published while our attorneys move these cases forward.
There’s no atrazine multidistrict litigation yet. Every atrazine lawsuit is currently proceeding as an individual filing in state or federal court.
Readers familiar with the Roundup non-Hodgkin’s lymphoma claims our firm handles will recognize the arc. Roundup litigation also began as scattered individual suits following an IARC classification.
The filing process varies by law firm. Some are advertising for adverse health effects broadly and holding cases without filing. Our atrazine attorneys screen every inquiry for diagnosis, exposure documentation, and venue before accepting it. We tell claimants plainly when the available evidence will not support a filing.
Syngenta has publicly disputed the IARC classification, and EPA has not changed its position that atrazine does not pose a cancer risk at registered use levels. Those positions shape how an atrazine lawsuit is pleaded and defended, and we walk clients through both before they decide anything.
How The IARC Reclassification Strengthens Atrazine Cancer Lawsuits
In November 2025, the International Agency for Research on Cancer (IARC) reclassified atrazine as a Group 2A carcinogen, meaning it is “probably carcinogenic to humans.” Scientists are now arguing that exposure to atrazine can present a significant cancer risk after twenty-two cancer experts found sufficient evidence of atrazine’s carcinogenicity in animals.
IARC reclassified the pesticide after finding limited evidence of cancer in humans combined with sufficient evidence from animal studies and strong mechanistic evidence. Group 2A is used when an agent is probably carcinogenic to humans, including circumstances involving limited evidence of cancer in humans combined with sufficient evidence in experimental animals.
For atrazine specifically, IARC identified positive associations with a form of non-Hodgkin lymphoma involving the t(14;18) chromosomal translocation.
The EPA has historically classified atrazine-containing products as “not likely to be carcinogenic to humans.” Atrazine lawyers today can use this when opposing experts dispute whether the pesticide exposure presents a carcinogenic hazard to humans.
What Is Atrazine & What Is Atrazine Found In?
Atrazine was developed by CIBA-GEIGY in 1958. It’s one of the most widely used herbicides in the country and is sold as a standalone product or an active ingredient in atrazine products, many of which don’t have obvious references to atrazine on the label.
Heaviest use falls on field corn, sweet corn, sorghum, and sugarcane crops, with registered non-agricultural application on nursery stock, ornamentals, and turf. USGS estimates of annual atrazine use put average U.S. application above 70 million pounds a year, concentrated on corn and sorghum crops. The European Union banned it in 2004.
However, most victims don’t recognize the word “atrazine.” This is the same product-identification problem we mapped for paraquat, and the table below exists to solve it.
| Product or Trade Name | Manufacturer | Where It Was Used |
|---|---|---|
| AAtrex / Atrex | Syngenta | Field corn, sweet corn, sorghum, sugarcane |
| Atratol | Syngenta | Non-crop and industrial vegetation control |
| Gesaprim | Syngenta | Corn and sorghum, widely used internationally |
| Acuron | Syngenta | Field corn, premix formulation |
| Primextra II Magnum | Syngenta | Corn, premix formulation |
| Bicep II Magnum | Syngenta | Corn and sorghum, premix formulation |
| Lumax | Syngenta | Corn, premix formulation |
| Lexar | Syngenta | Corn, premix formulation |
| Marksman | BASF | Corn and sorghum, premix formulation |
| Converge 480 | Bayer | Corn, premix formulation |
How People Are Exposed to Atrazine
Being exposed to atrazine isn’t a single event. Pesticide exposure accumulates across seasons through skin absorption, inhalation of spray drift and dust, and ingestion of contaminated drinking water. Legal investigations related to atrazine often combine personal injury claims with environmental advocacy efforts.
Farmers, Applicators, & Farmworkers
Farmers who rely on atrazine may face increased operational risks and potential shifts toward alternative weed management strategies due to legal pressures. Since farmers primarily apply pesticides such as atrazine, they are the highest-dose population. Mixers and loaders are at the absolute highest risk. Mixing concentrate, loading tanks, calibrating nozzles, and spraying all produce inhalation and dermal absorption, often without respiratory protection. The latest scientific evidence shows that around 71% of certified applicators reported using it. Since atrazine is one of the most widely used herbicides, workers exposed to drift from nearby applications are also at risk of developing non-Hodgkin’s lymphoma.
If you were exposed or injured on a Texas farm, or anywhere in the country, our atrazine attorneys can help.
Groundskeepers, Landscapers, & Turf Crews
Golf course crews, highway right-of-way applicators, sod farm workers, and nursery staff absorb lower doses per event but often across decades of continuous seasonal work. Protective equipment is inconsistent in these settings, and records for applying atrazine are frequently held by an employer rather than the worker.
Atrazine in Water: Rural Residents & Private Well Users
Atrazine, the most commonly detected pesticide in U.S. drinking water, threatens rural communities and private well users. Found in 75% of agricultural stream samples and detected over 600 miles from application sites, atrazine readily contaminates ground and surface water.
The EPA’s annual drinking-water standard for atrazine is 3 parts per billion. However, the EPA’s 3 ppb drinking water standard doesn’t cover private wells. Atrazine runoff harms aquatic life and has been found in rain, fog, and Arctic ice. Municipalities face high treatment costs and have sued manufacturers. As evidence mounts, pressure grows for the EPA to reassess atrazine’s safety and for stronger support for impacted communities.
Atrazine in Food
Atrazine persists in soil and water for decades after application. Residues can appear on treated crops and in commodities processed from them, though dietary intake is generally far lower than occupational or drinking water exposure.
Atrazine Effects on Humans: Illnesses & Cancers Linked to Atrazine Exposure
Studies linking atrazine to cancer and other health risks fuel ongoing advocacy for stricter regulations on its use. Atrazine cancer lawsuits must have scientific evidence. The following claims are backed by peer-reviewed research.
| Condition | What the Research Shows |
|---|---|
| Non-Hodgkin's lymphoma | RR 2.43 (95% CI 1.10 to 5.38) for ever-use among applicators under 50; IARC cited strong case-control associations with t(14;18)-positive NHL |
| Lung cancer | RR 1.24 (95% CI 1.04 to 1.46); suggestive association requiring confirmation |
| Aggressive prostate cancer | RR 3.04 (95% CI 1.61 to 5.75), highest exposure quartile, men under 60; suggestive association requiring confirmation |
| Kidney cancer | RR 1.62 (95% CI 1.15 to 2.29) in 25-year lagged analysis; suggestive association requiring confirmation |
All findings above come from the same cohort: 53,562 pesticide applicators in the Agricultural Health Study. Source: Remigio et al., Environmental Health Perspectives 132(2):27010.
Non-Hodgkin's Lymphoma
The primary human cancer linked to atrazine is non-Hodgkin lymphoma with t(14;18) translocation.
Non-Hodgkin’s lymphoma (NHL) is the crux of litigation against atrazine manufacturers, with a growing body of research drawing disturbing connections between this cancer and the widely used pesticide. When the International Agency for Research on Cancer (IARC) evaluated atrazine, NHL studies played a pivotal role in their assessment.
The AHS’s health study solidified these concerns. This expansive analysis tracked cancer incidence among 53,562 pesticide applicators. If under 50 years old. Atrazine applicators typically face a 2.43-fold increased risk of developing non-Hodgkin lymphoma.
The trend is especially concerning given the sheer scale of certified applicators and families at risk of drift from nearby applications. As the legal and scientific spotlight intensifies on this suspected link, pressure is mounting for a regulatory reappraisal and more aggressive steps to protect those on the front lines of atrazine exposure.
Other Cancers Under Investigation
Beyond non-Hodgkin lymphoma, the serious blood cancer most commonly associated with atrazine, researchers have tracked several other cancers due to atrazine’s role as a potent endocrine disruptor. Scientists are investigating cancer links to atrazine caused by endocrine disruption for the following.
Endocrine and Hormone-Dependent Cancers:
- Breast Cancer: Atrazine may boost the activity of an enzyme that raises estrogen levels, a known breast cancer risk factor.
- Prostate Cancer: Heavy atrazine exposure is associated with aggressive prostate cancer.
- Ovarian Cancer: Population studies are exploring higher ovarian cancer rates in areas with atrazine-contaminated drinking water.
- Thyroid Cancer: Agricultural workers with high atrazine use show a heightened risk of thyroid cancer diagnoses.
Solid Tumors & Systemic Malignancies:
New research is uncovering concerning patterns linking atrazine exposure to major solid tumors and blood cancers. According to PubMed scientific evidence, these include:
- Colon and Colorectal Cancer
- Lung Cancer
- Kidney and Bladder Cancer
- Soft Tissue Sarcoma
- Throat Cancer
- Multiple Myeloma
Reproductive Harm & Birth Defects Linked to Atrazine Under Investigation
Scientists are researching potential reproductive harms and birth defects linked to high atrazine use after growing concerns. Research suggests the pesticide may disrupt hormonal signaling even with low atrazine use, which could interfere with fetal development. Animal studies have connected prenatal atrazine exposure to low birth weight, heart and urinary tract defects, and altered sexual development.
Additionally, atrazine exposure is linked to immune system suppression, potentially leaving both mother and baby more vulnerable. While more research is needed to fully characterize the risks, the existing evidence warrants a precautionary approach to limit atrazine levels, especially for expecting mothers in farming families.
Do You Qualify to File an Atrazine Lawsuit?
Eligibility for an atrazine lawsuit requires:
- cancer diagnosis
- atrazine pesticide exposure
- filing window that hasn’t closed
The following is what our atrazine attorneys will look at:
- Diagnosed with non-Hodgkin’s lymphoma or another cancer under investigation
- Documented atrazine pesticide exposure occurring through agriculture, farming, groundskeeping, turf or nursery work, or long-term residence in a heavy-use watershed
- Median to highest exposure levels, typically over multiple seasons
- A latency window consistent with the non-Hodgkin’s lymphoma or cancer diagnosis
- Ability to identify atrazine products used, employers, farms, or application locations
- Diagnosis or death within the applicable filing window
Meeting every item on that list does not guarantee a case, and missing one does not end the inquiry. What actually sinks an atrazine lawsuit is an inability to connect a specific person to a specific product over a specific period, which is a documentation problem more often than a factual one.
The most common disqualifiers we see are a diagnosis outside the cancers currently supported by the literature, a single incidental exposure with no sustained application history, and a limitations period that expired before anyone thought to ask. Each of those is worth confirming rather than assuming.
An intake review looks at your pathology report and lymphoma subtype, the years and locations where you applied or lived near atrazine, the products you can name, the employment or property records that corroborate them, and the deadline that governs your state. We will tell you honestly whether an atrazine lawsuit is realistic.
You can request a free and confidential atrazine case review by phone or through the form on this page. Nothing about that conversation obligates you to file, and we do not charge for the evaluation regardless of the outcome.
Who Can Be Held Liable in an Atrazine Cancer Lawsuit
Syngenta invented atrazine and is the most prominent atrazine manufacturer worldwide. Other atrazine manufacturers and formulators, including BASF and Bayer, market atrazine-containing products under their own labels. Many top manufacturers may each bear liability for the warnings and testing for their own atrazine-containing products.
The complaint in the atrazine cancer lawsuits for non-Hodgkin’s lymphoma is straightforward: Syngenta and other atrazine manufacturers knew about the risk of developing cancer. They continued selling the pesticide despite clear science. This isn’t the first lawsuit against Syngenta.
Court documents unsealed from the groundwater contamination case showed that the company hired detective agencies to investigate scientists serving on federal advisory panels, judges, and critics of atrazine safety. Syngenta also hired professionals for psychological profiling, according to Environmental Health News. This was a multi-million-dollar campaign. In 2012, the manufacturer resolved a set of atrazine contamination lawsuits after regulators determined groundwater contamination affecting the community water systems in Southern Illinois. The $105 million settlement addressed the costs water providers incurred to remedy the waterways, according to Courthouse News Service, not personal injuries, like non-Hodgkin lymphoma.
If you’ve been diagnosed with non-Hodgkin lymphoma or cancer, similarly, our atrazine litigation attorneys will build claims from pesticide exposure records and internal company documents.
How the Supreme Court’s Durnell Ruling Changes Atrazine Claims
On June 25, 2026, the U.S. Supreme Court ruled in Monsanto Co. v. Durnell that federal pesticide law prevents states from requiring pesticide manufacturers to add cancer warnings when the EPA has already determined that they aren’t necessary.
What does this mean for victims?
Failure-to-warn was the most common pleading in pesticide exposure cases for the last decade. It’s now substantially weakened when the EPA rejects the warning label. However, this doesn’t end claims for cancer linked to atrazine use. Our atrazine lawyers can use other pleas, like design defect, negligent testing, marketing misrepresentation, and risks the EPA never evaluated.
If you were diagnosed with non-Hodgkin lymphoma or cancer after exposure to atrazine, ensure the attorney you hire is capable of sidestepping this recent “failure-to-warn” ruling.
Compensation Available in an Atrazine Cancer Lawsuit
Our Atrazine non-Hodgkin lymphoma attorneys seek full and fair compensation for the following and more:
- Past and future medical expenses, including chemotherapy, immunotherapy, stem cell transplant, long-term care, and transportation expenses
- Lost wages and diminished earning capacity
- Mental anguish, pain and suffering
- Physical impairment and disfigurement
- Loss of consortium and household services
- Wrongful death and survival damages
- Punitive damages when gross negligence is proven
Roundup and paraquat settlements can’t be used to determine settlement values here. What drives the value of atrazine cancer cases is the type of cancer you were diagnosed with, the cancer stage and age at diagnosis, and the strength of evidence you were exposed to atrazine.
Evidence That Supports an Atrazine Exposure Claim
Atrazine cases are won on documentation. The following can help prove the link between your exposure to atrazine and your lymphoma or cancer diagnosis.
- Oncology records, including pathology and immunophenotyping confirming you developed non-Hodgkin lymphoma and the subtype
- For agricultural workers: employment records, W-2s, or union records
- Pesticide applicator licensing and continuing education records
- Receipts or supplier records for atrazine products
- For agricultural workers or farm families: property records identifying acreage, crops, and application seasons
- Product labels, empty containers, or photographs of tank mixes
- Coworker or family affidavits
- Well testing results or municipal Consumer Confidence Reports
All of these aren’t required. We can reconstruct exposure to atrazine using supplier subpoenas, county agricultural records, and applicator licensing databases to fill the gaps.
Deadlines to File an Atrazine Lawsuit
Filing deadlines vary based on the state where the pesticide exposure occurs or where you live, not where the company manufactured atrazine. The windows run roughly 1-6 years, and several are already closing for diagnoses received in 2024 and 2025.
Scientific evidence is developing. Discovery rules can delay the statute of limitations until victims reasonably link atrazine exposure to their cancer diagnosis.
Claims that appear time-barred may still qualify under the discovery rule. The calculator is a quick-check only. Contact our law firm for a free review to determine eligibility.
How to File an Atrazine Lawsuit
If you were unknowingly exposed to atrazine and developed non-Hodgkin lymphoma or other adverse health effects, the following can help protect your legal rights:
- Free consultation: exposure history, diagnosis, and timeline screened by phone or form
- Records collection: medical, employment, and product documentation gathered and authorized
- Reconstruction for exposure to atrazine: application seasons, products, and locations mapped and quantified
- Causation linking atrazine exposure to injuries: pathology and exposure profile evaluated against the current literature
- Filing: individual complaint filed in the appropriate state or federal court
- Litigation: written discovery, depositions, and expert workup
- Resolution: settlement negotiation or trial
Because atrazine litigation is still developing, the scientific and medical evidence and legal process will shift while your case is pending. Our law firm does the same when tracking developments for other pesticide exposure cases. We brief clients when a ruling or trend changes their outlook.

Call 713-622-7271Atrazine Cancer Lawsuit FAQs
Is there an atrazine class action lawsuit?
No, there isn’t an atrazine class action lawsuit yet. Victims are filing claims individually. This means each plaintiff’s diagnosis, history, and damages are proven separately.
Is there an atrazine MDL?
No, there isn’t an atrazine MDL yet. If filing volume increases, plaintiffs may petition the Judicial Panel on Multidistrict Litigation to consolidate potential claims for pretrial proceedings, as happened in the Roundup and paraquat cases.
How much is an atrazine settlement worth?
Settlements for atrazine cases vary. Potential claims are still pending and haven’t gone to trial.
Is atrazine the same as Roundup or paraquat?
No, atrazine is not the same as Roundup or paraquat. Roundup’s active ingredient is glyphosate; paraquat is a separate herbicide, and atrazine is a chlorinated triazine. Different chemicals, different manufacturers, and different cases, though the plaintiffs overlap heavily.
Does atrazine cause Parkinson's disease?
While there may be increased risk of developing Parkinson’s disease, research hasn’t conclusively established that atrazine causes Parkinson’s disease in humans.
A 2024 epidemiological study found that greater atrazine application was associated with a higher risk of Parkinson’s disease. Researchers also found that atrazine exposure can produce changes involving dopaminergic neurons and other biological processes relevant to Parkinson’s disease. However, IARC’s classification of atrazine as probably carcinogenic to humans addresses cancer risk, not Parkinson’s disease.
Our law firm handles atrazine Parkinson’s disease claims. We evaluate potential claims based on the individual’s atrazine exposure, medical records, diagnosis, and available scientific evidence concerning the relationship.
What if I was exposed through my drinking water rather than at work?
Atrazine exposure through drinking water or residential lawn care is harder to document but not automatically excluded. Our law firm evaluates private well testing results, municipal Consumer Confidence Reports, watershed-level use data, and length of residence at the exposure address.
Can I file if my family member already died?
In most of the continental United States, yes, if a family member passed, you can file an atrazine wrongful death claim. Additionally, the decedent’s estate may bring a survival action for damages the person suffered before death. The statute of limitations generally runs from the date that your family member passed.
What does it cost to hire an atrazine lawyer?
There are no upfront costs for hiring an atrazine lawyer. Our law firm handles all potential claims on a contingency fee basis. This means clients don’t pay anything unless we reach a settlement or secure a verdict for you. We offer free consultations, and there’s no obligation to file claims.
Has the EPA banned atrazine or is atrazine banned in the U.S. at all?
No, the EPA hasn’t banned atrazine. Atrazine remains legal and widely used in the United States for several agricultural crops on American farmland. However, Atrazine is banned in over 60 countries. The European Union banned atrazine in 2004; Switzerland banned atrazine in 2012; France enacted a law in 2022 banning atrazine manufacture and export.
Is atrazine dangerous?
Yes, atrazine is dangerous. International Agency for Research on Cancer (IARC) officials classified atrazine as probably carcinogenic to humans in November 2025. However, the Environmental Protection Agency (EPA) maintains that it doesn’t present a cancer risk at normal atrazine exposure for registered use levels. Whether atrazine exposure is dangerous depends on the dose and duration.
There is never a fee unless we recover on your behalf.
Additionally, clients are not obligated to pay expenses if a recovery is not made.
