Useful:

• Canonical SMILES: OS(=O)(=O)O.[Cu]
• Aquaculture: Copper sulfate is widely used in aquaculture to treat infectious diseases caused by parasitic protozoa and crustaceans, such as Cryptobia sp., Trichodina sp., Chilodonella sp., and Sinergasilus sp.
• Umbilical Granuloma Treatment: Copper sulfate (CuSO4) is utilized for chemical cauterization in the treatment of umbilical granuloma, although it can cause superficial skin burns. An alternative treatment using table salt (NaCl) osmotically dehydrates granulation tissue, leading to necrosis.
• Historical Uses and Toxic Properties: Copper sulfate has been historically used for wound debridement due to its antiseptic properties and as an emetic agent in intoxications. It is found in certain dental cements and intrauterine devices. While poisoning is rare, it can lead to gastrointestinal disease, with oral ingestion being the most common route.
• Marine Parasite Control: Copper sulfate is employed to combat marine parasites like Cryptocaryon irritans, a harmful parasite in mariculture.
• Biotoxicity Studies: Copper sulfate is studied as a biotoxin, particularly its impact on seed germination and microbial growth inhibition. It has shown little impact on seed germination rates but is effective against oomycete pathogens like Phytophthora and Halophytophthora, suggesting its use as an antimicrobial treatment.
• Essential Trace Element: Copper (Cu) in the form of copper sulfate is essential for living organisms' efficient functioning. It acts as a potent oxidant and has a history of agricultural use as a fungicide, bactericide, and pesticide, particularly against smaller animals like snails. The toxicity of copper depends on factors such as physical form, dosage, and exposure period, with potential effects on embryos and growth rates.
