ACGIH RECOMMENDED LIMIT: None established
A. ACUTE TOXICITY
DERMAL: Prolonged contact to skin could cause irritation.
Absorption through skin is minimal (58).
ORAL: LD50 = 0.65 - 2.42 g/kg (rat) (58).
INHALATION: No hazards expected from inhalation (58).
EYES: Prolonged contact to eyes could cause irritation (58).
B. SUBACUTE AND CHRONIC TOXICITY:
Doses of 2 to 4 mg/kg of copper, the active ingredient, are
harmless to rats. Six to 9 mg/kg of copper may be harmful (58).
IV. ENVIRONMENTAL CONSIDERATIONS
Behavior In Or On Soils
1. Adsorption and leaching characteristics in basic soil types:
Complex may be adsorbed to soil particles in high organic
2. Resultant average persistence at recommended rates: May persist
indefinitely due to elemental nature of copper (58).
General to toxicity to wildlife and fish: Generally nontoxic to
fish and wildlife at recommended dosages. Trout, tropical
fish, ornamental goldfish, and certain other sensitive fishes
may be adversely affected in very soft water (below 50 ppm of
V. EMERGENCY AND FIRST AID PROCEDURES
The chemical information provided below has been condensed from
original source documents, primarily from "Recognition and Management
of Pesticide Poisonings", 3rd ed. by Donald P. Morgan, which have been
footnoted. This information has been provided in this form for your
convenience and general guidance only. In specific cases, further
consultation and reference may be required and is recommended. This
information is not intended as a substitute for a more exhaustive
review of the literature nor for the judgement of a physician or other
If poisoning is suspected, do not wait for symptoms to develop.
Contact a physician, the nearest hospital, or the nearest Poison
SYMPTOMS OF POISONING: Loss of appetite, jaundice, and
accumulation of copper in the liver (58).
SKIN CONTACT: Thoroughly wash contaminated skin (58).
INGESTION: If swallowed, call a doctor (58).
EYE CONTACT: Thoroughly wash contaminated eyes (58).
VI. FIRE AND EXPLOSION INFORMATION
Virtually noncorrosive (58).
Conditions to avoid: Contamination with acids, exposure of
granular formulation to temperatures above 150 F, especially if
material is damp (56).
VIII. PROTECTIVE MEASURES
