Dioxin
2,3,7,8 tetrachlorodibenzo-para-dioxin (TCDD)

• No commercial use
• Produced during production or destruction of
  chlorinated organic compounds
• 75 separate dioxin-like compounds

Most research is performed on TCDD because it has
the greatest potency

Dioxin and Cancer
In 1977, the International Agency for the
Research on Cancer (IARC) classified TCDD as a
class I (known) human carcinogen. Dioxin has been
linked with

• soft tissue sarcomas
• multiple myeloma
• lymphoma
• lung cancer

Human development is disrupted at vulnerable
stages by fetal and infant exposure to endocrine
disruptors.

Effects in Dutch PCB DioxinExposure Children

• In a study of 395 children in the Netherlands
  begun by the Dutch Government in 1989
• Prenatal PCB exposure related to lower birth
  weight, lower growth rate, lower psychomotor
  scores at 3 months
• Postnatal PCB Dioxin exposure was related to
  lower psychomotor development at 7 months
• At 42 months
• Prenatal PCB exposure associated with lower
  cognitive functioning
• Postnatal (lactation current) PCB Dioxin
  exposure unrelated to cognitive functioning

Faroe Islands Study

• Faroe Islands located SE of Iceland in the
  Norwegian Sea
• Homogeneous and isolated population of people who
  consume fish (1-3 meals of cod per week) and have
  episodic feasts of pilot whale
• Fish have low mercury content but pilot whale
  meat has a mean content methyl mercury content of
  1.9 ppm

16
Faroe Islands Study

• Prospective cohort study of 700 mother infant
  pairs enrolled at birth
• Mean mercury levels in mothers hair 6.8 ppm
  (range 0.5-27 ppm)
• Pilot whales contaminated with PCBs study
  controlled for PCB exposure

Seychelles Study

• Equatorial islands in the Indian ocean inhabited
  by a stable, cohesive, and homogeneous population
• Eat fish frequently (mean, 12 fish meals/week)
• Fish have relatively low methyl mercury
  concentrations (lt0.3 ppm)
• No adverse effects

MERCURY AND THE RISK OF CORONARY HEART DISEASE IN
MENAZUKO YOSHIZAWA, SC.D.,et al

• Toenail clippings were collected in 1987 from
  33,737 cohort members, and during five years of
  follow-up, we documented 470 cases of coronary
  heart disease (coronary-artery surgery, nonfatal
  myocardial infarction, and fatal coronary heart
  disease).
• The mercury level was not significantly
  associated with the risk of coronary heart
  disease.
• These findings do not support an association
  between total mercury exposure and the risk of
  coronary heart disease, but a weak relation
  cannot be ruled out.

Incineration

• Health effects of chronic exposure to dioxins and
  its accumulation on workers of a municipal solid
  waste incinerator
• Osaka Prefecture
• Takata T. Occupational Health Research and
  Development Center, Japan Industrial Safety and
  Health Association, 5-35-2 Shiba, Minato-ku,
  Tokyo 108-0014, Japan.
• Concentrations of dioxin among the blood of the
  workers who had engaged in maintenance of the
  furnace, the electric dust collector, and the wet
  scrubber of the incinerator were higher compared
  with those of residents in surrounding areas.

PEOPLE WHO LIVE NEAR INCINERATORS Show Evidence
Of Toxin Absorption

• Elevated dioxins were found in blood samples from
  communities near incinerators in several studies,
  but not others
• Miyata (1998) Deml et al. (1996) Van den Hazel
  and Frankort (1996) Startin et al. (1994)

• Dioxin levels in blood increased by 10-25
  percent during the two years following the
  startup of a new incinerator
• Gonzalez et al. (2000)

• PCB levels in the blood of children living near
  a German hazardous waste incinerator were
  elevated

  higher than those in workers and residents from
  the area around MSW incinerator.
