Description:

Atrazine is a herbicide applied to soil to control broadleaf and grassy weeds in agricultural crops, with limited use in other settings. It remains widely used globally, though restrictions and bans are in place in several countries. Atrazine is highly persistent in water and is a common contaminant of surface and groundwater.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Endocrine Disruption

May alter hormone function and contribute to chronic diseases and disorders.

Reproductive Toxicity

May alter hormone function and harm reproduction.

Developmental Toxicity

May impact fetal development and birth outcomes.

Organ System Toxicity

May cause organ damage and disease.

Immunotoxicity & Allergens

May impact immune system function or cause allergic reactions.

Irritant

May cause skin, eye, or respiratory irritation.

Ecotoxicity

May be toxic to ecosystems and wildlife.

Banned/restricted lists:

  • EU Regulation (EC) No 1107/2009 plant protection products (banned) EU Regulation (EC) No 396/2005 maximum residue limits (MRLs) US Safe Drinking Water Act (SDWA) (restricted use)

HOW MILLION MARKER SCORES CHEMICALS

Million Marker's Ingredient Hazard Scoring uses multiple chemical databases and a science-backed scoring system to compute hazard scores for thousands of chemicals found in consumer products and listed on ingredient labels.

We identified key chemicals based on a database compiling dozens of authoritative sources, screening tools, and QSAR models.

Hazard scores within 11 different health categories (carcinogens, endocrine disruptors, reproductive toxicants, developmental toxicants, genotoxicity, neurotoxicity, organ system toxicity, immunotoxicity, respiratory toxicity, skin/eye/respiratory irritants, and ecotoxicity).

They are weighted based on several factors, including strength of evidence for adverse impacts in humans, severity, and potential contamination.
