air pollution6
Air Pollution
  • Top ten most polluted cities in the world are in China and India
  • Most polluted areas in US:
    • LA, Houston, San Joaquin Valley in Central California, Pittsburgh
health effects of air pollution
Health Effects of Air Pollution
  • Causes approximately 60,000 - 75,000 premature deaths/yr. in U.S. (656,000 in China)
    • More than are killed by auto accidents
  • 1.8 million worldwide
health effects of air pollution8
Health Effects of Air Pollution
  • Air pollution causes asthma and impairs lung development and function
  • Deaths from cardiopulmonary diseases correlate with air pollution levels in US cities
    • Both day to day and over time
health effects of air pollution9
Health Effects of Air Pollution
  • Increased admissions for CHF, asthma, COPD, PVD, and cerebrovascular disease (stroke and TIA)
  • Increased lung cancer mortality
  • Decreased exercise tolerance, increased pulmonary symptoms
health effects of air pollution10
Health Effects of Air Pollution
  • Increased risk of DVT
  • Impaired sperm production

automobiles alternatives
Automobiles: Alternatives
  • Relatively low oil prices (until recently)

    • Convicted under Sherman Antitrust Act
automobiles alternatives19
Automobiles: Alternatives
  • Car sharing
  • Pay-as-you-drive auto insurance
  • “Peak Pricing” and “Congestion Fees”
    • E.g., London → 21% decrease in traffic, 43% increase in bus ridership, cleaner air

fetuses and children are most vulnerable to toxins
Fetuses and Children are Most Vulnerable to Toxins
  • Greater pound-for-pound exposure
  • Immature, porous blood brain barrier

The “Benefits” of Sterility-Causing Chemicals in the Workplace?

12 September 1977

Dr. Eula Bingham, Assistant Secretary for Occupational Safety and Health [Regarding] worker exposure to DBCP. While involuntary sterility caused by a manufactured chemical may be bad, it is not necessarily so. After all, there are many people who are now paying to have themselves sterilized to assure they will no longer be able to become parents... If possible sterility is the main problem, couldn’t workers who were old enough that they no longer wanted to have children accept such positions voluntarily? Or…some [workers] might volunteer for such workposts as an alternative to planned surgery for a vasectomy or tubal ligation, or as a means of getting around religious bans on birth control when they want no more children?

environmental success story the montreal protocol 1987
Environmental Success StoryThe Montreal Protocol (1987)
  • Phaseout of chlorofluorocarbons (CFCs) by 1996
  • Developed in 1920s; the chief working fluid in refrigerators, aerosol spray cans, insulating foams, and industrial solvents and cleaning agents

-1 million tons/year manufactured in 1970s

-major cause of Antarctic and Arctic ozone holes

-should disappear by 2060

-current substitute, HCFCs, much less damaging to ozone layer, also to be phased out

the montreal protocol
The Montreal Protocol
  • 1980 - 880,000 tons CFC’s produced worldwide
  • 1996 - 141,000 tons
  • 1996 - all industrialized nations stopped producing CFC’s
  • Today: Illegal CFC trade, once quite large, starting to taper off
  • 2010 - rest of world expected to stop

The Montreal Protocol
  • However, the Bush administration has withdrawn from the Treaty, under pressure from agribusiness and chemical lobbyists, who favor increased spraying of the pesticide methyl bromide (the most dangerous ozone-destroying chemical still in use)…..
toxic pollutants the basel convention
Toxic Pollutants:The Basel Convention
  • The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes (designed to control dumping of hazardous wastes from the industrialized world in developing countries)
toxic pollutants the basel convention125
Toxic Pollutants:The Basel Convention
  • Ratified by 170 countries
  • Despite being the largest producer of toxic pollutants in the world, the U.S. has signed but not ratified this agreement
persistent organic pollutants126
Persistent Organic Pollutants
  • UN Environmental Program organizing worldwide phaseout of top 12 through the Stockholm Convention on Persistent Organic Pollutants
    • Including DDT, PCBs, and dioxins
    • US has signed, but not ratified
  • American Assn. of Pediatrics now recommends toxic lead be removed from all housing and that all children be tested once during their first two years
  • 25% of U.S. homes still contain significant amounts of lead-based paint
    • Cost of removing lead from 4 million seriously affected homes: $28 billion
  • Cost savings each year thereafter: $43 billion (higher IQs, increased earning power, increased tax revenue, lower health care costs, less crime)
leaded gasoline
Leaded Gasoline
  • Banned in Canada in 1990, US in 1996 (after 25-year phaseout period), EU in 2002, Africa in 2006
    • Ban fought by industry for decades
    • Scientists harassed
  • Many countries still sell leaded gasoline:
    • Indonesia, Venezuela, North Korea, Iraq, Afghanistan, Jordan, Syria, Yemen
  • Registration, Evaluation, and Authorization of Chemicals
  • European Treaty requiring companies to test chemicals already on the market by a set timetable and test new products before putting them on the market
  • Cost of evaluations < 1% of chemical industry’s total sales
  • Economic analyses show REACH could bring environmental benefits worth €95 billion over the next 25 years and result in health cost savings of €50 billion over the next 30 years
medical waste131
Medical Waste
  • Organizations:
    • Health Care Without Harm
    • Green Health Center Movement
  • Hospitals built and operated on more environmentally sosund principles save money (NAS):
    • Costs recovered more quickly, patients get better sooner, patients’ families happier, medical errors reduced, steaf turnover/absenteeism/workers’ comp claims drop
solutions based on the precautionary principle
SolutionsBased on the Precautionary Principle

“When evidence points toward the potential of an activity to cause significant, widespread or irreparable harm to public health or the environment, options for avoiding that harm should be examined and pursued, even though the harm is not yet fully understood or proven”

the precautionary principle practical essentials
The Precautionary Principle:Practical Essentials
  • Give human and environmental health the benefit of doubt
  • Include appropriate public participation in the discussion
  • Gather unbiased, scientific, technological and socioeconomic information
  • Consider less risky alternatives
the precautionary principle
The Precautionary Principle
  • Endorsed by APHA, ANA, CMA, others
  • Puerto Rico, San Francisco have adopted, among others
  • Big business, US Chamber of Commerce oppose
the precautionary principle135
The Precautionary Principle
  • "All scientific work is incomplete - whether it be observational or experimental. All scientific work is liable to be upset or modified by advancing knowledge. That does not confer upon us a freedom to ignore the knowledge we already have, or to postpone the action it appears to demand at a given time." (Bradford Hill, 1965)
