Copper hydroxide is a Copper compound.

Report a Poisoning

Symptoms of Poisoning with Copper Compounds
Find Products Containing this Chemical

- Soluble salts are corrosive to mucous membranes and the cornea.
- Organic copper compounds are more absorbable and exhibit greater systemic toxicity than inorganic compounds.
- Irritation of skin, eyes, and respiratory tract, particularly to eyes.
- Metallic taste, nausea, vomiting and stomach pain.
- In more severe cases, there may be blood in vomit or black or tarry stools, jaundice and enlarged liver. Blood cells rupture resulting in circulatory collapse and shock.

First Aid for Copper hydroxide Poisoning

For Inhalation
- Remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen
For Skin
- IMMEDIATELY flush with copious amounts of water fro at least 15 minutes while removing contaminated clothing & shoes. Wash contaminated clothing before reuse. Discard contaminated shoes.
For Eyes
- IMMEDIATELY flush with copious amounts of water for at least 15 minutes. Assure adequate flushing of eyes by separating lids with fingers.
For Ingestion
- Wash out mouth with water
Get medical aid.

1. PAN Bad Actors are chemicals that are one or more of the following: highly acutely toxic, cholinesterase inhibitor, known/probable carcinogen, known groundwater pollutant or known reproductive or developmental toxicant. NOTE! Because there are no authoritative lists of Endocrine Disrupting (ED) chemicals, EDs are not yet considered PAN Bad Actor chemicals.

Summary of Acute Toxicity for Organism Group

Sorry, no honeybee acute toxicity data available for this chemical. Try related chemicals.

Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.
