Environmental degradation information is factored into estimates of exposure. The environmental degradation of polycarbonate grade Bisphenol A 2,2'-Bis (p-hydroxyphenyl propane) CAS NO. 80-05-7, used in the manufacture of plastics, was measured using local waters in the Houston Ship Channel. A spike of 3 mg/l BPA was added to four laboratory units containing fresh water (control), Houston Ship Channel water, Patricks Bayou water (200 yards downstream from a BPA chemical plant discharge), and the chemical plant treated process effluent. Greater than 90% degradation was observed in all treatments except the control within four days. The initiation of biodegradation in the units was in the following order: effluent > Particks Bayou > Houston Ship Channelbiodegradationbisphenol Achemical pollutantsD 04802 Pollution characteristics and fateindustrial effluentsinland water environmentmarine environmentnatural waterO 4060 Pollution - EnvironmentP 2000 FRESHWATER POLLUTIONphenolsQ1 01503 Characteristics,behavior and fateQ2 02445 Characteristics,behavior and fateUSAUSA,Texas,Houston Ship ChannelJournal
