Sources of exposure:

Pesticides

Historical mosquito-control sprays, residential insecticides, public-health pest-control formulations, and treated outdoor environments

Description:

Resmethrin is a synthetic pyrethroid insecticide used to control mosquitoes and other insects. It acts on insect nervous systems by affecting voltage-gated sodium channels. Its use has been discontinued in the United States, although historical applications and uses in other jurisdictions may remain relevant.

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.

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.
