and his colleagues analysed the effects of pesticides over broad regions. The team examined 23 streams in the central plains of Germany
They classified streams according to three different levels of pesticide contamination: uncontaminated, slightly contaminated and highly contaminated.
Moreover, the authors say that diversity decreased at pesticide concentrations that European regulations deem environmentally protective.
Considering pesticides along with other known threats to biodiversity may be crucial for halting species declines, she says.

#Pollinating Bees Are The Pesticide Deliverymen Of The Futurehere's another reason to pay attention to dwindling bee populations:
Bees might be the organic pesticide spreaders of the future. While they go to work pollinating our crops bees could simultaneously bring natural microbial pest control agents to help those crops stave off disease.
Using a technique called bee vectoring researchers force bees to walk through a pesticide before they can exit their hives coating them in a fungus bacterium
Scientists have suggested that this colony collapse disorder could be the result of long-term exposure to a class of pesticides called neonicotinoids
but CBC News writes that the type of organic pesticides used in bee vectoring are not harmful to the bee (or us for that matter).

In order to improve the evaluation process for the long-term consequences of pesticides scientists have developed a new detection method
whether and how readily biodegradable the residues of pesticides are. The study conducted by scientists at the Helmholtz-Centre for Environmental Research (UFZ) the Rhine-Westphalian Technical University Aachen (RWTH)
Pesticides have a bad reputation: they harm the environment have negative effects on the diversity of species
Pesticides are important for the efficacy of our modern agriculture methods. And pesticides are not necessarily pesticides--differentiation is necessary in this context.
Generally speaking biodegradability is supposed to be the top priority when deploying pesticides says Prof. Dr. Matthias Kästner Director of the Department Environmental biotechnology at the Helmholtz-Centre for Environmental Research--UFZ in Leipzig.
Worldwide today approximately 5000 pesticides are utilized as substances for plant protection and for pest control.
As varied as their respective effectiveness is their effects on the environment are varied equally. Some pesticides are biodegraded quickly
while others take longer. And some of them create chemical bonds with components in the soil and form the so-called bound residues.
This is why pesticides that form more than 70%bound residues are no longer in compliance today. Kästner:
and his team applied pesticides onto various reference soils and examined them thoroughly regarding their fate.
For this purpose they initially marked the pesticide to be examined with the nonradioactive heavy carbon isotope 13c
In this manner the scientists were able to determine the residues the changes in the pesticide and its breakdown products in the soil.
As regards Type 1 the pesticide itself or its breakdown products of organic materials are deposited in the soil (humus)
If the pesticide has undergone a chemical bond with the humus bound residues are allocated to the Type 2
whether or not approval of a pesticide that forms such residues in the soil is possible and defensible says Matthias Kästner.
As regards residues of the Type 3 the pesticide was decomposed by bacteria and the carbon contained therein was transported into the microbial biomass.
Pesticides from which the bound residues in the soil are allocated to Type 3 could thus be approved without risk in the future.
Conversely pesticides which heretofore were considered to be risk-free could possibly be classified as critical using this method.
Kästner says Only when we are capable of differentiating between biodegradable and high-risk pesticide residues we can act accordingly.
Thus for the residues of the approved pesticides 2. 4 dichlorphenoxyacetic acid (2. 4-D for short) and 2 methyl 4 chlorphenoxyacetic acid (MCPA for short) they were able to give the all-clear.
In order to better control the deployment of pesticides and their environmental consequences we still have a lot of work to do says Kästner The problems that we had with DDT (dichlorodiphenyltrichloroethane)
Therefore it is very important to understand what actually happens with pesticides after application. Story Source:
#Risk assessment for pesticides in EU unsuitable for use in fieldthe method used to approve pesticides in the EU needs to be revised.
According to the study the level of fungicides measured in surface waters is often much higher than the level predicted by the current calculation model used in the approval process.
Almost half of all pesticides used in the EU are fungicides. As they are used normally as a preventive measure they are applied routinely in larger quantities particularly in wine growing.
When it rains for instance the pesticides are washed into rivers and lakes where in higher concentrations they can result in effects on aquatic organisms.
This is because many fungicides do not specifically combat fungi but prevent general processes in cells such as energy production
or cell mitosis. In order to calculate the concentrations of pesticides in surface waters when applied correctly in agriculture the EU has been using mathematical simulation models (FOCUS models) since the end of the 1990s.
A pesticide may only be approved in Europe if the concentrations predicted by the model are below the environmentally acceptable threshold.
Dr. Ralf Schulz has compared now 417 measured field concentrations of fungicides in surface waters and sediments with the environmental concentrations predicted by FOCUS.
and animal life in surface waters nor do they predict properly the level of fungicide concentrations actually found later in surface waters explains Prof Dr. Ralf Schulz of the Institute for Environmental sciences Landau of the University of Koblenz-Landau.
and herbicides relatively little is known about the effects of fungicides on ecosystems. Initial studies indicate though that they may possibly have a strong effect on amphibians such as frogs.
The differences between the measured and calculated concentrations might be due not just to an unsuitable calculation model but also the incorrect application of pesticides by farmers or the publication of inadequate application instructions by manufacturers.
either for insecticides or fungicides adds Schulz. The FOCUS predictions have therefore proven to be unreliable for use in the field
In any case based on the concentrations of pesticides actually measured their approval and application guidelines should be revised and where applicable modified after a few years.
Accordingly we need data on the pollution of surface waters with pesticides to be collected regularly and independently in Germany as well.

Their discoveries described in a paper published online today in Cell include identification of a molecule that protects neurons from pesticide damage.
For the first time we have used human stem cells derived from Parkinson's disease patients to show that a genetic mutation combined with exposure to pesticides creates a'double hit'scenario producing free radicals in neurons that disable specific molecular pathways that cause nerve-cell death
Until now the link between pesticides and Parkinson's disease was based mainly on animal studies and epidemiological research that demonstrated an increased risk of disease among farmers rural populations
and mutant neurons to pesticides--including paraquat maneb or rotenone--created excessive free radicals in cells with the mutation causing damage to dopamine-containing neurons that led to cell death said Frank Soldner M d. research scientist in Jaenisch's lab
In fact we observed the detrimental effects of these pesticides with short exposures to doses well below EPA-accepted levels said Scott Ryan Ph d. researcher in the Del E. Webb Center
Having access to genetically matched neurons with the exception of a single mutation simplified the interpretation of the genetic contribution to pesticide-induced neuronal death.
when exposed to pesticides disrupt a key mitochondrial pathway--called MEF2C-PGC1ALPHA--that normally protects neurons that contain dopamine.
The free radicals attacked the MEF2C protein leading to the loss of function of this pathway that would otherwise have protected the nerve cells from the pesticides.
and the molecules that were altered by the pesticides we used high-throughput screening to identify molecules that could inhibit the effect of free radicals on the pathway said Ambasudhan.
which mutant neurons from cell death induced by the tested pesticides. Since several FDA-approved drugs contain derivatives of isoxazole our findings may have potential clinical implications for repurposing these drugs to treat Parkinson's.

#Endometriosis risk linked to two pesticidesa Fred Hutchinson Cancer Research center-led study has found that two organochlorine pesticides are associated with an increased risk of endometriosis a condition that affects up to 10 percent of reproductive
Specifically researchers observed that women with higher exposures to two such pesticides beta-hexachlorocyclohexane and mirex had a 30-to 70-percent increase in endometriosis risk.
Since endometriosis is driven an estrogen condition we were interested in investigating the role of environmental chemicals that have estrogenic properties such as organochlorine pesticides on the risk of the disease she said.
despite organochlorine pesticides being restricted in use or banned in the U s. for the past several decades these chemicals were detectable in the blood samples of women in our study
Organochlorine pesticides have demonstrated generally estrogenic properties in laboratory studies of human tissue and adverse reproductive effects in laboratory studies of other model organisms altering the function of the uterus
and ovaries as well as hormone production Given these actions it's plausible that organochlorine pesticides could increase the risk of an estrogen-driven disease such as endometriosis Upson said.
#Male birth defect weakly linked to pesticide exposurea study of several hundred chemicals used in commercial pesticides has found only weak evidence that any of them are associated with a common birth defect in male infants.
