New credit or inquiries from creditors show on your Experian credit report for two years, but only the last year impacts your FICO Score. Sometime opening several credit accounts in a short period of time represents a greater risk to lenders-especially if there isn't also an established credit history on record.
PCBs are mainly broken down either by the effect (direct or indirect) of sunlight or by microorganisms. In general, the persistence of PCB congeners increases with the number of chlorine atoms. Sunlight can play a role in the breakdown of PCBs present in air, water and surface soil. In the atmosphere, PCBs that are present in the atmosphere tend to react with ozone and water under the effect of sunlight.
Chlorine breaks off from CFCs and destroys the ozone. Ozone is a protective layer in the upper atmosphere. It is formed, when oxygen molecules absorb short wavelength ultra â¦ violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere.hen CFCs are present in the stratosphere they reacted on by ultra violet light to release a chloride ion. The ion breaks down an ozone molecule to create an oxygen molecule and ionic oxygen.
