Children's Health Issues - Body Burden and Chemical Injury

THE CHEMICAL SOUP WE LIVE IN


Persistent Organic Pollutants (POPs)
are widely distributed in the environment and have been shown to have an adverse effect on the health of humans, animals and the environment.

POP’s characteristics include that they are:

Toxic

Persistent (do not readily break down)

Accumulate in the bodies of animals (high affinity for fatty tissue)

Able to leach out of consumer products during normal use

Found to be contaminants in the human body


Persistent Toxic Substances
(PTS) [also referred to as POPs] are found in a large range of everyday household products including alkylphenols, bisphenol A, brominated flame retardants, chlorinated paraffins, organotins, phthalates and artificial musks.

Children are at greater risk from exposure to carcinogens than adults

The US government in 2003 released the final draft of their revised US Guidelines for cancer risk assessment. In this report they assume that children are more vulnerable to the effects of certain carcinogens than adults

The US EPAs final draft of their new guidelines for cancer risk assessment recognises individual susceptibility and that there is variation between people.

Children aged two and younger have ten times the cancer risk of adults when exposed to mutagenic carcinogens which cause cancer through direct damage to DNA.

Children between the ages of two and fifteen are considered to have three times the risk of adults.

Mutagenic carcinogens include arsenic, benzene, formaldehyde, mutagen X, brominated organics and polycyclic aromatic hydrocarbons. Child exposures are under rated as some carcinogens have been shown to be around 65 times more potent when exposure occurs during childhood. The EPA data shows that half of lifetime cancer risk accumulates in the first two years of life. The guidelines are available online at www.epa.gov/ncea/raf/cancer2003.htm

Evidence of Developmental Harm: Neurotoxic effects of chemicals.

A 2005 review by Lanphear, Vorhees and Bellinger,  ‘Protecting Children from Environmental Toxins. Toxicity testing of pesticides and industrial chemicals is a crucial step’found that:

  1. Over last 30 years it has become evident that low level exposures to toxins are linked with less obvious symptoms of toxicity such as Intellectual Impairment, Behavioural problems, spontaneous abortions, and Preterm births.
  2. Current toxicity testing has crude toxicological endpoints such as death, body weight or organ dysfunction. “The existing tests may miss important less overt effects such as mood changes, impulsive behaviours and attentional problems that in humans have been shown to result from exposures to environmental toxins”
  3. Children have enhanced vulnerability to chemicals and evidence exists for lead, methyl mercury, polychlorinated bisphenyls (PCBs) and tobacco. In some cases greater effects are seen at low levels
    than higher levels. The intake limits established by animal (rodent) studies have been insufficient to protect human health compared with the epidemiological (longer term effects seen in real life) studies. These have since shown that these limits were insufficient to protect children from low level exposures.
  4. Current testing procedures do not adequately test for neurotoxic effects and what testing is done is on adult animals and only in single species. An important case in point is thalidomide testing the gross birth defects were induced in rabbits but not rats – interspecies variations.
  5. Exposures to other chemicals or mixtures of chemicals are not yet studied or not in any detail. Many of the chemicals or metabolites are routinely found in blood and body fluids of pregnant women and children.
  6. Exposure to environmental toxins is insidious. Exposures start transplacentally during fetal development followed by direct ingestion via house dust, soil, breast milk and other dietary sources.
  7. We have increased knowledge and means to test BUT testing for developmental neurotoxicity (DNT) and reproductive toxicity is rarely done. Currently in the US DNT testing only requested where pre-existing evidence of problem.
  8. Prevalence of diseases and disabilities linked to environmental toxins. According to parental reports in the US 1/6 children has 1 or more developmental disabilities (from subtle learning disability to overt behavioural or emotional disorders).
  9. Exposure to environmental toxins has been linked with
    1. Higher rates of mental retardation, intellectual impairment and behavioural problems (such as conduct disorder, ADHD)
    2. 1/10 babies born preterm
    3. approximately 5% have low birth weight
    4. lead, tobacco smoke & DDT linked with increased risk of spontaneous abortion, low birth weight or preterm birth.
  10. The rate of occurrence and these disorders is increasing as is treatment for ADHD in children.
