Question

Adverse effect copper contamination of soil pollution

Answer 1

Explanation:

Copper pollution in the environment comes from human activities and natural sources. The excavation of copper in mines creates dust rich with the metal and wind can spread it around the mine site. Manufacturing companies dealing with copper in the production of metal, electrical appliances, pesticides, fungicides and other products containing copper, often release contaminated water into the drainage system which leads to streams and other water bodies. The use of pesticides such as “Bordeaux mix” also introduces more copper compounds into the environment and may affect humans consuming unwashed fruits or vegetables sprayed with such pesticides. In buildings, copper used in plumbing dissolves gradually and adds the metal into the water supply. Other sources of copper pollution include fossil fuel burning, used motor oils, paint, and wearing out of brake pads as well as some birth control methods.

Answer 2

Answer:

Excess copper in the soil creates a toxic environment for most micro-organisms such as bacteria. Copper toxicity in the soil inhibits mineralization of nutrients such as phosphorus and nitrogen since the metal gets attached to minerals and organic matter.
