Learning Objectives Identify sources of PCB’s Discuss health effects of PCB’s Review actions for reducing exposures to PCB’s
4
PCB’s Identified 209 different chemical compounds Trade name – Aroclor, banned since 1978 Oily liquids or solids, colorless to light yellow Products made in 1977 or before still exist and are being phased out
5
PCB’s Uses Coolants / lubricants in transformers, capacitors Hydraulic fluid Adhesives Fire retardants Pesticides Inks Carbonless reproducing papers May still be around,products made before 1978, such as: Old fluorescent lighting Electrical Devices Microscope and hydraulic oils
6
PCB’s & the Environment Persistent in the environment Travel very far away – Artic circle Build up in environment and affect human health, contaminate the marine food chain NO ONE is PCB-free, stored in body fat, very slowly eliminated
7
How We Can Be Exposed Old fluorescent lighting Old electrical appliances and devices such as TV’s and refrigerators May leak while heating up and cause skin exposure
8
How We Can Be Exposed Contaminated food : Fish caught in contaminated waters Red meat Pork Dairy Fats Oils
9
How Can We Be Exposed? Contaminated air around hazardous waste sites At work While preparing and maintaining PCB transformers Accidental fires or spills Improper disposal
10
PCB’s and Your Health Lung and nose irritation Abdominal pain Affect blood and liver function Fatigue Headache Numbness and tingling
11
Health Effects : Skin Chloracne – a sever form of acne Rashes Gray – brown discoloration
12
Health Effects : Infants Exposed via placental transfer or breast milk Low birth weight Problem with motor skill Decreased short-term memory Depressed immune function Decreased IQ of at least 5 points Defects in teeth enamel
13
Health Effects : Children More susceptible because body weight, diet, activities, still developing vital systems Decreased reading comprehension, possibly higher incidence of ear infections
14
Health Effects : Hormonal Disrupts hormones such as : Thyroid Estrogen Testosterone Steroids
15
Health Effects : Cancer Suspected to be cancer – causing Probable cancers : GI Lymph and blood systems Liver Gall bladder tract Skin Pancreas
16
Protect Yourself Protect Your Family Have well water and soil tested Remove shoes at the door Vacuum, damp mop, and dust your home often Limit eating fish caught in contaminated areas, check with Department of the Environment for fish Advisories
17
Protect Yourself Protect Your Family Breast feeding is still recommended Benefits outweigh any possible exposure to PCB’s in breast milk Do not let children play with or put soil or dirt in their mouth
18
Protect Yourself Protect Your Family Avoid exposure to : Old electrical equipment Old appliances Contaminated soil and water Children in particular should not play in hazardous waste sites
19
What To Do: If exposed at work : Shower and change at work Wash clothes separately PCB’s can be carried home from work
20
What To Do: Encourage industry to continue clean up of PCB’s and properly dispose of them PCB’s can be clean up through Dehalogenation (chemical process to remove halogens), dig and remove, dredging, and incineration with a special incinerator
21
In Review What are PCB’s and how are we exposed to them How do PCB’s effect our health How can we reduce our exposure to PCB’s
