- Copper(II) Sulphate (CuO4S) is very poisonous for micro-organism and has a long lasting effect on the environment. It produce H2SO4 when it come in contact with air and heat which is harmful for environment.
- Magnesium (Mg) can create poisonous and irritating smog, fire even this can occurs explosion when it is come in contact with air which is dangerous to all.
- Sodium Disulphide (Na2S2) Create allergy.
- Zinc Oxide (OZn) is very dangerous because it is corrosive.
- Zinc (Zn) increase the acidity of water and cause a great harm to the environment.
