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.
Since the CFCs contain chlorine, breaking them up would result in the release of these reactive atoms. Each chlorine atom combined with one oxygen atom from an ozone molecule, which is also reactive, to yield a chlorine monoxide molecule and an oxygen molecule. In other words, the CFCsâ chlorine atoms attack ozone.While this process of CFCs dissociating is happening, the ultraviolet radiation also causes oxygen molecules to break down into free oxygen atoms.ince the CFCs contain chlorine, breaking them up would result in the release of these reactive atoms.
