Low-level toxicity of chemicals: No acceptable levels?

Over the past 3 decades, in a series of studies on some of the most extensively studied toxic chemicals and pollutants, scientists have found that the amount of toxic chemical linked with the development of a disease or death—which is central to determining "safe" or "hazardous" levels—is proportionately greater at the lowest dose or levels of exposure.

Health Risks of Pesticides

Pesticides are a convenient way to get rid of the pests in our homes and gardens and on the farms that grow the food we eat. Yet, the increased use of pesticides has been linked to a number of serious health risks. Some pesticides are irritating to the skin and eyes. Others, including organophosphates, have been linked to nervous system damage and to the development of Parkinson's disease. Pesticide exposure has also been associated with a greater risk for some cancers, including non-Hodgkin's lymphoma.

Study Finds Pesticide Residues Linked to Infertility and Miscarriage

According to a new study published in the Journal of the American Medical Association (JAMA) there is a connection between pesticide residues and an increased risk of infertility. Even in those who are able to conceive, there is a greater risk of miscarriage due to pesticide exposures. The study examined 325 women undergoing fertility treatments—researchers found a link between those who ate more fruits and vegetables high in pesticide residues and their likelihood of having a baby than those who did not.

Die Insekten stehen am Anfang der Nahrungskette. Wenn sie verschwinden, verschwinden wir auch.

Der Entomologische Verein Krefeld, der seit 1905 Insekten erforscht, hat festgestellt, dass in den letzten 20 Jahren 80% unserer Fluginsekten verschwunden sind: http://80.153.81.79/~publ/mitt-evk-2013-1.pdf . Mit in 2 Malaise-Fallen gefangenen Insekten wurden dieser Verlust in einem Naturschutzgebiet ermittelt. Nicht nur eine industrialisierte Landwirtschaft und die damit verbundene Vernichtung der Lebensräume von Insekten sind dafür ursächlich.

Is it time to reassess current safety standards for glyphosate-based herbicides?

Use of glyphosate-based herbicides (GBHs) increased ∼100-fold from 1974 to 2014. Additional increases are expected due to widespread emergence of glyphosateresistant weeds, increased application of GBHs, and preharvest uses of GBHs as desiccants. Current safety assessments rely heavily on studies conducted over 30 years ago. We have considered information on GBH use, exposures, mechanisms of action, toxicity and epidemiology. Human exposures to glyphosate are rising, and a number of in vitro and in vivo studies challenge the basis for the current safety assessment of glyphosate and GBHs.

New study exposes link between pesticides and childhood brain tumours

A new study from the Telethon Institute for Child Health Research has revealed a potential link between professional pesticide treatments in the home and a higher risk of children developing brain tumours. Published this week in the international journal Cancer Causes & Control, the study found that exposure by parents to professional pesticide treatments prior to conception could increase the chances of a child developing a brain tumour.

Autism and Environmental Pollution

If you look just at the numbers, you might think autism rates are spiraling out of control. The rates seemed high enough at 1 in 150 in 2000, when public health officials started tracking a steady rise in the syndrome in the United States. And by the time estimates finally flatlined in 2012 at 1 in 68, many parents had embraced unfounded theories blaming vaccines for an autism “epidemic,” helping to fuel outbreaks of measles and other once rare diseases.

Neonicotinoid Residue Found In Iowa Drinking Water

It was only in 2015 that the US Geological Survey first studied whether neonicotinoid residue shows up in streams (it does), and new research from the University of Iowa is the first to find it in drinking water. This new study tested water from drinking taps throughout Iowa City for neonicotinoid presence. Iowa City is on the smaller side, with an estimated population of fewer than 75,000, but its presence in a largely agricultural state makes it well-placed to see how nearby pesticide use can affect an urban area.

Pesticides linked to birth abnormalities in major new study

High exposure to pesticides as a result of living near farmers’ fields appears to increase the risk of giving birth to a baby with “abnormalities” by about 9 per cent, according to new research. Researchers from the University of California, Santa Barbara, compared 500,000 birth records for people born in the San Joaquin Valley between 1997 and 2011 and levels of pesticides used in the area. The average use of pesticides over that period was about 975kg for each 2.6sq km area per year.
