4 Sources of Pollutants Average US household uses 40 lbs of chemicals each year Average household stores more than 60 hazardous products Loaded with fragrances and petroleum- distilled chemicals Volatile Organic Compounds (VOCs)

5 Sources of Pollutants (cont.) Paints, paint strippers, and other solvents Wood preservatives Aerosol sprays Cleansers and disinfectants Moth repellents Air fresheners Stored fuels and automotive products Hobby supplies Dry-cleaned clothing

6 Sources of Pollutants (cont.) Laundry detergents and fabric softeners Phthalates Chemicals harmed hormonal systems Harmed reproductive organs in animal tests Make the scent last longer

7 Sources of Pollutants (cont.) Chlorine bleach Also called sodium hypochlorite Caustic fumes Toxic if swallowed Scented products Perfumes and deodorants

8 Sources of Pollutants (cont.) Pesticides Used inside and outside home Can be tracked into home from outside

9 Sources of Pollutants (cont.) Dry cleaning CA Air Resources Board designated perchloroethylene (PERC) as a toxic air contaminant If you dry clean traditional way –Air your clothes before wearing or placing in closet Alternative Choice -Hydrocarbon solvent -Wet cleaning

10 Sources of Pollutants (cont.) Pungent, colorless, toxic, water-soluble gas Disinfectant Preservative Ingredient of synthetic resins, dyes, plastics

11 Sources of Formaldehyde Building materials Pressed wood products Particleboard Hardwood plywood paneling Medium density fiberboard Smoking Household products Un-vented, fuel-burning appliances Manufactured products Permanent press qualities to clothing and drapery Component of glues and adhesives Preservative in paints

12 Mercury Sources Lighting Fluorescent HID Mercury Vapor Other Thermostat Kids shoes

13 Sources of Pollutants (cont.) How Air Fresheners Work Interfere with ability to smell by way of nerve- deadening agent Coat nasal passages with undetectable oil film Cover up one smell with another (Rarely) break down offensive odor Air fresheners do little to freshen the air

14 Health Effects Depend on… Toxicity of chemical Level of exposure Length of time exposed Pathway of exposure

15 Health Effects Eye, nose, and throat irritation Headaches Loss of coordination / dizziness Nausea Damage to liver, kidney, and central nervous system Suspected or known to cause cancer in humans Allergic skin reaction Fatigue

16 Health Effects (cont.) Children born into households using toxic cleaning products twice as likely to have wheezing Over last years, level of toxins stored in body’s adipose tissue (fat cells) have risen

17 Health Concerns of Pesticides Child in household using home and garden pesticides has 6.5 x higher risk of developing leukemia Neurotoxins Irritants Carcinogens Mutagens Endocrine disruptors Health Effects of Pesticides

18 Formaldehyde Health Concerns Watery eyes Burning sensation in the eyes and throat Nausea Difficulty breathing Shown to cause cancer in animals and may cause cancer in humans Eyes, nose, and throat irritation Wheezing and coughing Fatigue Skin rash Allergic reactions

19 Steps to Reduce Exposure Increase ventilation Meet or exceed any label precautions Do not store opened containers of unused paints and similar materials Throw away unused or little-used containers safely; buy in quantities that you will use soon Never mix household care products unless directed on label Follow label instructions carefully

20 Steps to Reduce Exposure (cont.) Use least toxic product that works for your project Make homemade alternative cleaning products using baking soda, vinegar, soap Provide adequate ventilation Keep out of reach of children and pets

22 Reduce Pesticide Exposure (cont.) Best products for environment and your health are less toxic and less persistent Dispose of unwanted pesticides through the Household Hazardous Waste Program

23 Reduce Formaldehyde Exposure Use “exterior-grade” pressed wood products Provide adequate ventilation Maintain moderate temperature and humidity levels Use materials not containing formaldehyde
