Mecoprop

Synonyms: (+/-)-2-(4-Chloro-2-methylphenoxy)propionic acid, mecoprop-P, MCPP-P

CAS Number: 93-65-2

Sources of exposure:

Lawn and turf herbicides; golf courses; ornamental landscaping; contaminated soil and water

Description:

Mecoprop is a chlorophenoxy herbicide used to control broadleaf weeds. In current US pesticide products, the active ingredient is commonly mecoprop-P, also called MCPP-P, the herbicide active enantiomer of mecoprop. It is used in lawn-care and "weed-and-feed" products and on residential, commercial, athletic, and golf-course turf, as well as in some ornamental and non-crop settings.

Health concerns:

Irritant

May cause skin, eye, or respiratory irritation.

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.
