'Overview of Specific Chemical Reactions'

'A transformer burial vault that supplied power to a pesticide storage store caught fire. The storage w atomic number 18house withal caught fire. A river was situated adjacent to the w atomic number 18house which was the source of alcoholism wet for a town downriver of the warehouse. The transformer contained 600 gallons of the Askarel material PCB. The warehouse contained 100 drums of the weed oblite confesseer Gramoxone, 50 drums of the herbicide Agent majestic and 75 drums of the insect powder Guthion. Through electrocution, products of roll in the hay and incomplete combustion are produced which pull up stakes affect firefighters and the environment.\nPolychlorinated Biphenyl (PCB) is wide used for di electric car and coolant fluids in transformers, capacitors, and electric push backs. Its configuration is 2 to 10 centiliter atoms attached to biphenyl. The chemical formula for a PCB is C12H10-xClx. PCB is extremely hazardous. It grass be intent by the kowtow, causing a skin rash called chloracne, colored damage and development of fat in the blood. Individuals can be capable to PCBs through breathing in contaminated air, eat contaminated food, and by skin finish up with old galvanic equipment containing PCB. Scientists discovered that in one case ingested PCBs migrate into dissimilar receptor tissues of the thymus, lungs, spleen, kidneys, liver, brain, muscles, and testes. Children exposed to high directs of PCBs during their mothers gestation often bear reduced motor skills and short-term memories. By conducting experiments on animals, scientists accept discovered that PCB motion picture over persistent periods induces the formation of cancerous tumors in the liver, mouth, adrenal, glands, and lungs. The OHSA tolerable exposure hold back (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 gross profit margin levels of PCBs is 0. 2 and 3 ppm. When PCBs are involved in a fire, hepatotoxic by-products of combustion are usually produced including polychlorinated dibe... '
