When was the first Earth Day ? When was the first Earth Day ? • April 22, 1970 Monday 4/18/11 Monday 4/18/11 • Collect Knollwood Dupage County Waste Water • • • Plant Report Return Issue 17: POP’s and Grade Sheets Lecture Chap 22: Hazardous Chemicals Pollution and Prevention VT 8: Chemistry and the Environment • The Knollwood facility serves the City of Darien, the Village of Willowbrook, the Village of Burr Ridge and unincorporated areas in the southeast part of the County. The estimated population of this area is 60,000. In 1999, the Knollwood facility operated at 94% of capacity. The facility utilizes a secondary treatment process which consists of preliminary treatment of grit removal and fine bar screening for removal of paper, wood, and plastic products. Biological treatment is provided by complete­mix aeration tanks. Biologically treated waste is directed to clarifiers that separate the biological solids form the treated liquid. This effluent is then chlorinated for disinfection and dechlorinated prior to discharge to the Des Plaines River. Waste biological solids are hauled to the Woodridge ­ Greene Valley facility for further processing Chap 19: Hazardous Chemicals: Chap 19: Hazardous Chemicals: Pollution and Prevention pp. 485 ­ 507 Hazmat Placards p. 487 Hazmat Placards p. 487 Hazmat Placards Hazmat Placards The Nature of Chemical Hazards: The Nature of Chemical Hazards: HAZMATs Chemicals That Present Hazard or Risk – Ignitability: catch fire readily; gasoline – Corrosivity: corrode storage tanks and equipment; acids – Reactivity: unstable and may explode or create toxic fumes when mixed with water; explosives, concentrated sulfuric acid – Toxicity: injurious to health; pesticides, chlorine p. 486 p. 486 Sources of Chemical Pollution p. 488 Toxics Release Inventory (see Fig. 19­4) Toxics Release Inventory (see Fig. 19­4) p. 488 • For 2004: – 1,549 million pounds of toxic chemicals released to the air – 241 million pounds of toxic chemicals released to the water – 2,454 million pounds of toxic chemicals released at land disposal sites – Total environmental release = 4,244 million pounds Toxics Release Inventory Toxics Release Inventory (see Fig. 19­4) p. 487 • Emergency planning and community right­ to­know act (EPCRA) 1986 – Industries must report locations and quantities of toxic chemicals stored on site and releases of toxic chemicals The Threat from Toxic Chemicals The Threat from Toxic Chemicals p. 488 ­ 491 • Many are broken down by natural processes • Two types persist in the environment – Heavy metals – Synthetic organics Heavy Metals p. 489 Heavy Metals p. 489 • Lead, mercury, arsenic, cadmium, tin, chromium, zinc, copper • Used in metal­working, paint, and pesticides, among other products Heavy Metals p. 489 Heavy Metals p. 489 • Soluble in water and readily absorbed by body. • Interfere with enzyme function. • Example: mental retardation from lead poisoning.
