Sources of exposure:

Food
Pesticides

Agricultural herbicides, treated corn and soybean fields, contaminated agricultural runoff, drinking water, and potential food residues

Description:

Metolachlor is a chloroacetanilide herbicide used to control annual grasses and certain broadleaf weeds in agricultural crops. It interferes with the synthesis of very-long-chain fatty acids in susceptible plants. Exposure may occur during pesticide application, through agricultural residues, or through contaminated surface water and groundwater.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Immunotoxicity & Allergens

May impact immune system function or cause allergic reactions.

Ecotoxicity

May be toxic to ecosystems and wildlife.

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.
