Sources of exposure:

Pesticides

Historical agricultural insecticide applications, contaminated soil, water and environmental residues

Description:

Parathion is an organophosphate insecticide formerly used to control a broad range of insect pests on agricultural crops. It was applied to fruits, vegetables, and field crops. Potential exposure is primarily associated with historical pesticide use, contaminated environments, or handling of legacy pesticide materials.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Developmental Toxicity

May impact fetal development and birth outcomes.

Neurotoxicity

May impact brain function or development.

Organ System Toxicity

May cause organ damage and disease.

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.
