Sources of exposure:

Pesticides

Historical household insecticides, cockroach and ant control products, treated indoor surfaces, older pest-control formulations, and contaminated indoor dust

Description:

Propoxur is a carbamate insecticide historically used to control cockroaches, ants, and other household or agricultural pests. It acts by inhibiting acetylcholinesterase, an enzyme involved in nerve signaling. Many uses have been discontinued or restricted in the United States. Exposure may occur through older pest-control products, contaminated indoor environments, or applications in jurisdictions where use remains permitted.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Neurotoxicity

May impact brain function or development.

Ecotoxicity

May be toxic to ecosystems and wildlife.

Banned/restricted lists:

  • California Proposition 65 - OEHHA - cancer

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.
