Chemicaliën en psyche
Bijna iedereen denkt dat chemische stoffen
alleen lichamelijke symptomen kunnen veroorzaken. Maar er wordt steeds meer bewijs
gevonden (onder meer door natuurgenezers) dat alledaagse huishoudmiddelen de oorzaak
kunnen zijn van een heel scala van zogenaamde mentale verschijnselen: van paniek tot
hyperactiviteit.

Chemical Additives - Are They
Slowly Killing Our Children?
Let me start by saying a chemical additive doesn't necessarily 'appear' to be a problem
immediately after ingestion. Quite often the effects are cumulative; a gradual build-up in
the body produces roller-coaster days, some good, some bad. Some children are more
sensitive to food chemicals and display immediate effects soon after ingestion of
additives, colours in particular. In small amounts additives are not harmful. Effects are
dose related and, tragically, dose for weight, children are consuming several times more
additives than the acceptable daily intake (ADI). Before we get into the details of the
most common problem foods, it is necessary to understand the testing and approval process,
with emphasis on those factors that may confer the level of risk of toxic additives in
infants and young children's diets.

PFOS and PFOA exposure associated
with lower birth weight and size
Exposure to perfluorooctane sulfonate and perfluorooctanoate in the womb is statistically
associated with lower weight and head circumference at birth, according to an analysis of
nearly 300 umbilical cord blood samples led by researchers at the Johns Hopkins Bloomberg
School of Public Health.

A cohort study of in utero
polychlorinated biphenyl (PCB) exposures in relation to secondary sex ratio
Polychlorinated biphenyls (PCBs) are ubiquitous industrial chemicals that persist in the
environment and in human fatty tissue. PCBs are related to a class of compounds known as
dioxins, specifically 2,3,7,8-TCDD (tetrachloro-dibenzodioxin), which has been implicated
as a cause of altered sex ratio, especially in relation to paternal exposures.

Toxic chemicals found in common
scented laundry products, air fresheners
A University of Washington study of top-selling laundry products and air fresheners found
the products emitted dozens of different chemicals. All six products tested gave off at
least one chemical regulated as toxic or hazardous under federal laws, but none of those
chemicals was listed on the product labels.

Chemical Causes of Diabetes -
Overeating Is Not the Only Problem
Medical science has discovered how sensitive the insulin receptor sites are to chemical
poisoning. Metals such as cadmium, mercury, arsenic, lead, fluoride and possibly aluminum
may play a role in the actual destruction of beta cells through stimulating an auto-immune
reaction to them after they have bonded to these cells in the pancreas. It is because
mercury and lead attach themselves at highly vulnerable junctures of proteins that they
find their great capacity to provoke morphological changes in the body. Changes in
pancreatic function are among the pathogenetic mechanisms observable during lead
intoxication.

Chemicals used as fire retardants
could be harmful, UC-Riverside researchers say
Margarita Curras-Collazo's lab at the University of California-Riverside has done research
that shows that polybrominated diphenyl ethers, chemicals used as fire retardants, disrupt
mechanisms that are responsible for releasing hormones in the body. Moreover, her lab has
shown that like polychlorinated biphenyls, whose manufacture in the US was discontinued in
1977, PBDEs alter calcium signaling in the brain.

Agent Orange Chemical, Dioxin,
Attacks The Mitochondria To Cause Cancer, Study Shows
Researchers with the University of Pennsylvania School of Veterinary Medicine have
demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular
machinery, disrupts normal cellular function and ultimately promotes tumor progression.

Nurses threatened by chemicals
The very chemicals used to keep hospitals squeaky clean and to treat patients could be

The mass poisoning of humanity - an
exploration of human stupidity
As human beings, we're the only species stupid enough to actually poison ourselves. As
part of modern living, we create a wide variety of chemical toxins that go into the
ecosystem through rivers and streams, the air, the soil and so on. Not only that, we
actually synthesize toxic chemicals and then inject them directly into the food supply --
knowing full well that they are poisonous and are major contributors to the epidemic rates
of chronic disease we are experiencing today.

Household Exposure to Toxic
Chemicals Lurks Unrecognized, Researchers Find
Although Americans are becoming increasingly aware of toxic chemical exposure from
everyday household products like bisphenol A in some baby bottles and lead in some toys,
women do not readily connect typical household products with personal chemical exposure
and related adverse health effects, according to research from the December issue of the
Journal of Health and Social Behavior. Brown University sociologist Phil Brown is a
co-author of the study. People more readily equate pollution with large-scale
contamination and environmental disasters, yet the products and activities that form the
backdrop to our everyday lives electronics, cleaners, beauty products, food
packaging are a significant source of daily personal chemical exposure that
accumulates over time, said sociologist Rebecca Gasior Altman, lead author of the
study, Pollution Comes Home and Gets Personal - Womens Experience of Household
Chemical Exposure. Altman received a Ph.D. from Brown in 2008.

Exposure to organochlorate
pollutants and lead weakens animals bones, according to a study
A new methodology developed by a researcher of the University of Granada will permit to
determine the toxicological effects caused in animals which have been exposed to
organochlorate pollutants and lead analysing their bones. This work has studied the
effects of lead toxicity in the long term in wild birds populations, determining how this
heavy metal causes bone weakening and fracture, provoking therefore a fall in the
individual survival of the affected species. This work has been carried out by Pedro
Álvarez Lloret, of the Department of Mineralogy and Petrology of the University of
Granada, in collaboration with the University of Georgia (USA), the Karolinska Institute
of Stockholm, the Research Institute for Hunting Resources (CSIC) and the Biological
Station of Doñana (CSIC). The research work has been supervised by Professor Alejandro
Rodríguez Navarro.

Persistent pollutant may promote
obesity
A persistent pollutant, tributyltin, has effects on gene activity in a wide range of
animal species at concentrations of parts per billion. Tributyl tin and its chemical
relatives bind to nuclear receptors that in turn activate genes influencing the formation
of fat storage cells. This and other evidence suggests a possible role for tributyl tin in
the obesity epidemic.

fast-acting cyanide antidote
University of Minnesota Center for Drug Design and Minneapolis VA Medical Center

has potential to save lives of those who are exposed to the chemical -- namely
firefighters, industrial workers and victims of terrorist attacks.
