'Overview of Specific Chemical Reactions'

'A transformer drop that supplied power to a pesticide storage store caught fire. The store excessively caught fire. A river was regain adjacent to the w arhouse which was the source of drunkenness irrigate for a town downstream of the w arehouse. The transformer contained 600 gallons of the Askarel material PCB. The warehouse contained 100 drums of the weed eliminateer Gramoxone, 50 drums of the weedkiller Agent empurpled and 75 drums of the insect powder Guthion. Through combustion, products of sub and incomplete combustion are produced which go forth affect firefighters and the environment.\nPolychlorinated Biphenyl (PCB) is astray used for insulator and coolant fluids in transformers, capacitors, and voltaic tugs. Its configu layaboution is 2 to 10 centiliter atoms attached to biphenyl. The chemical formula for a PCB is C12H10-xClx. PCB is extremely hazardous. It washbasin be oblivious finished the fur, cause a skin rash called chloracne, colored damage an d change magnitude of fat in the blood. Individuals can be assailable to PCBs through breathing in contaminated air, down contaminated food, and by skin get through with old galvanic equipment containing PCB. Scientists discovered that at one time ingested PCBs migrate into respective(a) receptor tissues of the thymus, lungs, spleen, kidneys, liver, brain, muscles, and testes. Children exposed to high levels of PCBs during their mothers maternalism often pass reduced motor skills and short-term memories. By conducting experiments on animals, scientists grow discovered that PCB movie over want periods induces the formation of cancerous tumors in the liver, mouth, adrenal, glands, and lungs. The OHSA allowable exposure do (PEL) is 1mg/m ³. The LD50 to kill a rat is 8.65g/kg. For drinking water the maximum level contamination of PCBs is .0005 ppm. And for food, the allowance account levels of PCBs is 0.2 and 3 ppm. When PCBs are involved in a fire, toxic by-products of combustion are usually produced including polychlorinated dibe... '
