1 Persistent Bioaccumulative Toxins And why we shouldn’t eat them

2

3 Mercury Neurological effects “Mad Hatter” “Cabin Fever” Fluorescent and neon bulbs Switches Dentists Preservatives (thimerosol)

4 Lead Lowered IQ, shortened attention span, kidney destruction, miscarriage, weakness, mutated sperm, infertility, impotence, anemia Fluorescent bulbs Batteries Paint Bullets Fishing sinkers - waterfowl

5 Lead in Cars Batteries Wheel balancing weights Alloys & coatings Electronics PVC stabilizers Nickel Metal Hydride Tin, Steel Lead free or limited Lead free solder Polypropylene

6 Lead from Automobiles

7 Cadmium Batteries Pigments & coatings Stabilizer (PVC) Lung cancer, kidney destruction, hypertension

8 Alkyl phenols (nonyl phenol) Used in detergents Pesticide carrier Shampoo Don’t break down quickly Endocrine disruptors P&G, Health Canada

9

10 Triclosan Chlorinated phenoxy phenol Dioxin Found in human milk (weak endocrine effect) Toxic to aquatic environments Microban in plastic and clothing (Playskool) Biofresh in acrylic Common in soap (Dial, Softsoap)

11 PBDE (Polybrominated Diphenyl Ethers) Fire retardant Computers Rugs Furniture cushions Automobiles and airplanes Endocrine disruption (brain development) Sale Banned in Washington (RCW 70.76.020) Except Deca-BDE Recycled or previously owned

12 PVC Produces dioxin when burned or manufactured Cadmium and Lead are used in PVC (stabilizers) Ubiquitous (most “vinyl”) D-ring binders ID cards Automobiles Better – polyolefin, polypropylene, polyethylene

13 Phthalates (dibutyl phthalate, etc.) Plasticizer in PVC Raingear 3-ring binders Vinyl flooring Blood bags IV tubing Soaps Liver & kidney damage, endocrine disruption, birth defects – weak associations Alkyl Citrates are better

14 Metro-Effluent is a Complex Mixture of Compounds 0 2 4 6 8 10 Alkylphenols Triclosan Plasticizers Fragrances DEET Pharmaceuticals  g/L

15 Bisphenol A Endocrine disruptor Breast cancer, low sperm count, infertility Neurotoxicity, obesity Food cans Beverage containers (polycarbonate) Affects legume signalling
