Are chlorinated hydrocarbons biodegradable?
Biodegradation of chlorinated hydrocarbons is not significant.
Are chlorinated hydrocarbons found in solvents?
Yes, chlorinated hydrocarbons are commonly found in solvents. They are often used as cleaning agents, degreasers, and in manufacturing processes. However, they have been associated with health and environmental concerns due to their toxicity and persistence in the environment.
Who first proposed a correlation between chlorinated hydrocarbons and ozone depletion?
The correlation between chlorinated hydrocarbons and ozone depletion was first proposed by chemists Rowland and Molina in a paper published in 1974. They showed that chlorofluorocarbons (CFCs) released into the atmosphere could reach the stratosphere where they catalyze the breakdown of ozone molecules.
Is organic solvent an oxidizing agent?
Organic solvent can be an oxidizing agent in some circumstances but usually is not. All hydrocarbon solvents, chlorinated hydrocarbons and ethers are not for example.
Can ozone reform?
Ozone can reform in the atmosphere through natural processes. Ultraviolet radiation from the sun can break apart oxygen molecules, resulting in the formation of ozone. Additionally, certain atmospheric reactions can facilitate the regeneration of ozone.

What is responsible for making the hole in the ozone layer?
Monatomic chlorine transported by chlorinated-fluorinated hydrocarbons (e.g. freons, CFCs) used in refrigerators, freezers, air conditioners, aerosol cans, etc. The monatomic chlorine acts as a catalyst, with one chlorine atom decomposing many thousands of molecules of ozone to oxygen before being removed or neutralized. This effect is many orders of magnitude larger than the natural variation with the seasons and has the potential of destroying the entire ozone layer if the use of chlorinated-fluorinated hydrocarbons is uncontrolled. However, fluorinated hydrocarbons (FCs) and hydro-chlorinated-fluorinated hydrocarbons (HCFCs) can perform the same functions as CFCs without transporting chlorine to the ozone layer. FCs contain no chlorine and HCFCs break apart in the lower atmosphere.
Which pollution is caused by paint industry?
Heavy metals, xylene, other BTEX, Pesticides, Chlorinated Hydrocarbons

What is it call when a substance that dissolve in water?
It is said to be water soluble. Other materials may be soluble in oils, aromatic hydrocarbons, or chlorinated compounds.

What chemicals are used in insecticides?
Two common are shared by most insecticide chemicals. They are chlorinated hydrocarbons and organophosphates. Newer chemicals include parathion and malathion.
