- 【Exposure Standards and Regulations】
- In accordance with 21 CFR 184.1(b)(1), the ingredient is used in food with no limitation other than current good manufacturing practice. The affirmation of this ingredient as generally recognized as safe (GRAS) as a direct human food ingredient is based upon the following current good manufacturing practice conditions of use: 1) The ingredient is used as a nutrient supplement as defined in 21 CFR 170.3(o)(20) of this chapter and as a processing aid as defined in 21 CFR 170.3(o)(24) of this chapter. 2) The ingredient is used in food at levels not to exceed current good manufacturing practice. Copper sulfate may be used in infant formula in accordance with section 412(g) of the Federal Food, Drug, and Cosmetic Act (the act) or with regulations promulgated under section 412(a)(2) of the act. Prior sanctions for this ingredient different from the uses established in this section do not exist or have been waived.
Trace minerals added to animal feeds. These substances added to animal feeds as nutritional dietary supplements are generally recognized as safe when added are levels consistent with good feeding practice. Element: Copper; Source compound: copper sulfate. (All substances listed may be in anhydrous or hydrated form.)
- 【Reactivities and Incompatibilities】
- Anhydrous copper sulfate causes hydroxylamine to ignite & the hydrated salt is vigorously reduced.
Solutions of sodium hypobromite are decomposed by powerful catalytic action of cupric ions, even as impurities. /Cupric salts/
- 【Other Preventative Measures】
- Personnel protection: Keep upwind. ... Avoid breathing vapors or dusts. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
If material not involved in fire: Keep material out of water sources & sewers. Build dikes to contain flow as necessary.
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.

Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire.?
2.Handling and Storage?
Handling: Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing.?

Copper and its compounds are on the Community Right-To-Know List. Copper Sulphate (CAS NO.7758-98-7) is reported in EPA TSCA Inventory. EPA Genetic Toxicology Program.
- 【Disposal Methods】
- SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Group III Containers (both combustible and non-combustible) that previously held organic mercury, lead, cadmium, arsenic, or inorganic pesticides should be triple rinsed, punctured and disposed of in a sanitary landfill. Non-rinsed containers should be encapsulated and buried at a specially designated landfill site. /Organic mercury, lead, cadmium, arsenic, or inorganic pesticides/
The following wastewater treatment technologies have been investigated for copper (II) sulfate: activated carbon.
Add slowly to a large container of water. Stir in slight excess of soda ash. Let stand for 24 hr. Decant or siphon into another container and neutralize with 6 M HCl. ... The sludge may be added to landfill. Recommendable methods: Precipitation, solidification, & landfill. Peer-review: ... Copper can be recovered by cation exchange.

- 【Biomedical Effects and Toxicity】
- Effect of hydrogen ion (H+) concentration, water hardness, suspended solids, fish age, size, and species, acclimatization to copper, and levels of copper in food on poisoning of fish by copper sulfate used as a herbicide in freshwater ponds is discussed. Copper levels in muscle, kidney, and organs of rainbow trout were approximately 0.8-1.1, 2.0-2.3, and 115-150 mg/kg fresh weight, respectively, after 12 months intermittent exposure to various copper sulfate containing formulations 0.6, 2.0, and 100 mg/kg, respectively, in controls ... .
Male rats were orally administered for 2, 5, and 11 days with 0.5 mmol/kg of copper cmpd. ... In the case of cupric carbonate, copper was much more distributed in the tissues, especially in the liver, than for copper sulfate. The copper level increased progresively in mitochondria lysosomal fractions of the liver in proportion to the period of administration. In the 105,000 g supernatant fraction, copper was distributed in the metallothionein fraction rather than in the superoxide dismutase fraction. The administration of copper cmpd resulted in an increase in the zinc level in the liver, kidney and spleen, preferentially in the metallothionein fraction of the liver, but it seemed to have little effect on iron metabolism.
Environmental Fate and Exposure Potential
- 【Environmental Fate/Exposure Summary】
- Terrestrial Fate: In soil, copper sulfate is partly washed down to lower levels, partly bound by soil components, and partly oxidatively transformed.
... Granular copper sulfate /was applied/ to the surface of Hoover Reservoir, Franklin County, Ohio. Soluble and particulate cupric copper concn at several depths were measured by atomic absorption spectrophotometry for four days after application. The soluble cupric copper concn decreased to near baseline values in 2 to 6 hr when 0.2 or 0.4 g of copper sulfate per square meter were added to the surface. Most of the copper sulfate was dissolved in the first 1.75 m of the water column, and only 2 percent of the total copper sulfate reached the depth of approx 4.5 m.
