Mancozeb
is registered as a general use pesticide by the U.S. Environmental Protection
Agency (EPA). In July 1987, the Environmental Protection Agency announced the
initiation of a special review of the ethylene bisdithiocarbamates (EBDCs), a
class of chemicals to which
mancozeb
belongs. This Special Review was initiated because of concerns raised by
laboratory tests on rats and mice. The EPA was concerned about
- potential effects on the general population from dietary exposure to
residues left on food crops and
- potential occupational health risks to workers who handle and/or apply EBDC
pesticides.
As part of the Special Review, EPA reviewed data from
market basket surveys and concluded that actual levels of EBDC residues on
produce purchased by consumers are too low to affect human health. The EPA
concluded its Special Review in April, 1992 with new label requirements for
protective clothing to be worn by industrial and agricultural workers, and with
the establishment of a 24-hour reentry period for agricultural workers. Many
homegarden uses of EBDCs have been canceled because the EPA has assumed that
home users of these pesticides do not wear protective clothing during
application. Toxicity data reviewed by the EPA as part of their Special Review
of EBDCs are included in this document under "Toxicological Effects."
