Cathey Eisner Falvo, MD, MPH
President, International Society of Doctors for the
Environment
representing Physicians for Social Responsibility
Cooper Hospital, April 27, 2011
Learning objectives
• Understand the burden of pediatric
disease from environmental pollution
• Know some of the leading environmental
pollutants in your area
• Understand the need for an environmental
history as part of the pediatric visit
• Have some tools for helping your patients
avoid environmental toxic exposure
WHO
• 24% disease burden in the world is from
environmental exposures*
• “About 3 million children under five die
annually from largely preventable
environment-related causes”**
Environmental causes of ill-health
• Injury-motor vehicles, sports,
• Industry-factories, agriculture, power
sources
• Fires
• Buildings

WHAT ARE "POPs" ?
 Synthetic organic chemicals
Persistent in environment
 Long-range transport leads to global
pollution
 Lipophilic
 Accumulate in food-chain
High levels in fish and marine mammals

Triclosan
• Soaps and sanitizers
• Toothpaste
• A wide variety of commercial antimicrobial use
– incorporated in conveyor belts, fire hoses, dye bath
vats, or ice-making equipment
– commercial HVAC coils, adhesives, fabrics, vinyl,
plastics (toys, toothbrushes), polyethylene,
polyurethane, polypropylene, floor wax emulsions,
textiles (footwear, clothing), caulking compounds,
sealants, rubber, carpeting
• An endocrince disrupter
Health effects –Hg
• Central nervous system
– sever damage with coma and death
– learning disabilities-attention deficit
– hearing loss
– tremors
Mercury (Hg)
• Three (3) forms
– Hgo - elemental, quicksilver
– Hg+, Hg++- salts
– organic mercury-methyl, ethyl, phenyl
Mercury cycle
• Mercury can go from one form to another
in the presence of bacteria, sunlight, and
other catalysts
• Mercury accumulates in the food chain
• It deposits in muscle, not fat, of animals
Mercury
environmental sources
• In rock, fossil fuel, and water - released
into air as vapor
• Industrial catalyst and solvent
• Pesticides and fungicides
• Food = fish
• Various electronics-computer monitors
Mercury-environ. source 2

Light switches
Cosmetics
Pharmaceuticals and folk remedies
Batteries
Lamps and light bulbs
A word about climate change
• Burning fossil fuel is a major source of
green house gases
• Burning fossil fuel is a major cause of
acute and chronic respiratory disease
• Burning fossil fuel is a major source
mercury
• Burning trash is a major source of
mercury, dioxin, arsenic, furans, etc
(depending on what is burned)
What can you and your patients
do?
• Ask as part of the patients history
– Parents/patients occupational & hobby history
– Neighborhood, including multifamily dwelling exposure
• Reduce, reuse, recycle, compost
• Read labels-plastics with #1, 2, 4 and 5 are safer
• Only use “microwave safe” labeled containers in the
microwave oven
• Lock up chemicals (in original container)
• No smoking/other fires in home
• Keep car idling to a minimum and never in a closed
space (garage)
• Have smoke and carbon monoxide detectors in the
home
Action
2
• Wash hands after bathroom and before eating
• Fishing? Check state advisory for contamination
• Eat a variety of foods
• TAKE ACTION in your community, and at
the state and federal level
Some contaminants are beyond you and your
patients’ ability to control
Children represent the
future of nations.
They need cleaner, safer and
healthier environments – free
of POPs and other pollutants.
Clean environments and
education will enable children
to reach their full potential as
individuals,
as contributing members of
society and as pillars for
sustainable development
