Component Naled DDVP Naphthalene
Synonyms 1,2-Dibromo-2,2-dichloroethyldimethylphosphate;DIBROM? 2,2-Dichloroethenyldimethylphosphate;DICHLORVOS
CAS Number 300-76-5 62-73-7 91-20-3

DANGER! POISON! CORROSIVE! An off-white to straw yellow liquid with
a sharp, pungent odor that causes irreversible eye and skin damage. May be
fatal if swallowed, inhaled or absorbed through skin and eyes. Is a
cholinesterase inhibitor. Rapidly absorbed through skin. Repeated inhalation
or skin contact may, without symptoms, progressively increase susceptibility
to organophosphate (including Naled) poisoning. May be an aspiration
hazard. May cause an allergic reaction.
Product is combustible.
Toxic to fish, birds, and other wildlife.

CARCINOGENICITY: There is no evidence of carcinogenicity in laboratory animals tested with
Naled Technical. EPA under its 1999 proposed Guidelines for Carcinogen Risk Assessment
has classified DDVP, an impurity in Naled, as having "suggestive evidence of
carcinogenicity, but not sufficient to assess human carcinogenic potential.". IARC lists
DDVP (Dichlorvos) as being possibly carcinogenic to humans (Group 2B). Based on the
results of testing in mice, the IARC has recently classified Naphthalene, a component of the
solvent used for this formulation, as being possibly carcinogenic to humans (Group 2B).
CARE SHOULD BE EXERCISED IN HANDLING THIS FORMULATION.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Preexisting conditions which
lower cholinesterase levels increase vulnerability to cholinesterase depression. These
include: (for plasma) genetic cholinesterase deficiency; advanced liver disease; chronic
alcoholism; malnutrition; dermatomyositis; existing toxicity from exposure to carbon
disulfide; benzalkonium salts, organic mercury compounds, ciguatoxins or solanines; and (for
RBC) hemolytic anemias.
