OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is harmful to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

NOTES
Mecoprop is a chlorophenoxy-herbicide which, as a group, has been classified by IARC (1987) as possibly carcinogenic to humans, but the data on this specific substance are inconclusive. Carrier solvents used in commercial formulations may change physical and toxicological properties. Other CAS number: 7085-19-0 .
