Calif. Dept. of Pesticide Regulation proposes to designate Endosulfan as a toxic air contaminant

The Department of Pesticide Regulation is proposing to add the organochlorine insecticide endosulfan to California 's list of Toxic Air Contaminants (TACs). The addition will have no immediate effect on usage of the pesticide, but may lead to further restrictions on the pesticide’s use. A...

Atrazine and phosphorus in surface waters greatly increase the infection of frogs by trematodes

In prior posts a number of different research reports have been reviewed that have sought to address the reason for the decline in frog populations, sometimes locally, sometimes on a broader scale. The latest addition to the theories is the herbicide Atrazine (see http://en.wikipedia.org/wiki/Atrazine...

Scientists begin to zero in on honeybee colony collapse disorder with pesticides and Israeli acute paralytic virus seeming to play major roles

As noted in prior posts, there have been a multitude of theories regarding the cause of honeybee colony collapse (including the far out, such as cell phone signals), which was first reported in November 2006. See, for example, http://www.epa.gov/pesticides/about/intheworks/honeybee.htm . One of the scientifically...

Honey bee buzz may help to minimize caterpillar damage

Sometimes researchers stumble across the most interesting relationships and find fascinating, hard-to-spot interspecies relationships. Many caterpillars have sensory hairs that react to the sound of a wasp's wings as its flies nearby; no surprise given that many wasps kill caterpillars either for...

Sulfuryl fluoride, long touted as a cost-effective substitute for methyl bromide, may have significant GHG impacts

Methyl bromide [ http://en.wikipedia.org/wiki/Bromomethane ] has been a widely used soil fumigant. Its product was phased out in 2005 under the 1987 Montréal Protocol which was designed to preserve the ozone layer. [See http://www.epa.gov/spdpublc/mbr/index.html .] However, the treaty exempts...

Exposure to multiple pesticides simultaneously adversely affects salmon even if each individual pesticide causes no harm

Salmon runs along parts of the West Coast of the U.S. have been down. One of the multitude of theses about the cause has been that the salmon are exposed to pesticides in the rivers. In lab tests, researchers exposed juvenile coho salmon to the five pesticides in various combinations, killing some fish...

Evolutionary theory may help to identify strategies for insect suppression

Malaria kills a million humans a year, and debilitates hundreds of millions more. New drugs have been introduced, such as Artemisia, but already resistance is appearing in some geographical areas. Scientists are also working on a vaccine, but such tools are still unproven. Insecticides to kill the mosquito...

Why is so-called organic produce more nutritious? Stress

Why is organically farmed produce [fruits, vegetables] more nutritious that conventionally farmed produce? A recent study indicates that antioxidant vitamins, flavonoids, and other beneficial (for humans) trace nutrients are actually produced to help plants defend themselves from pests and the botanical...

EPA to test 67 pesticide chemicals to ascertain if they are endocrine disruptors; eventually all pesticide chemicals to be tested

EPA has identified the first 67 pesticide chemicals to be assessed as potential endocrine disruptors; ultimately the program will require that all pesticide chemicals be tested. Although the notice disclaims that any inference should be drawn regarding the chemicals listed, dibutyl phthalate, Di-sec...

EPA revokes "tolerances" for carbofuran; pesticide may be banned

Carbofuran has been approved in the past to control pests, such as beetles, grasshoppers, aphids and other insects, for a variety of crops, including alfalfa, green coffee beans, cotton, potatoes, soybeans and certain types of corn. Granular carbofuran is approved for use on spinach grown for seed, pine...

A new study indicates that the pesticides pendimethalin and EPTC are associated with an increased rate of pancreatic cancer among applicators and their spouses

Pancreatic cancer is a rare disease. Producing few early symptoms, the disease is unfortunately usually diagnosed only once the cancer is advanced. However, even it is found fairly early and removed, only one in five patients survive five years. There is also no effective cure. It is thus no surprise...

Lead, mercury, dieldrin, and heptachlor may explain a significant quantity of the excess liver disease in U.S.

Researchers had previously found that a link between high occupational exposures to chemicals and liver disease, but it had remained unknown whether chronic, low-level exposure to pollutants was associated with liver abnormalities in the general population. To address that question they used data from...

6th Cir. stays pesticide ruling so EPA can issue general permits for applications in, over, or near waters of the U.S.

Prior posts have noted cases, such as those in the 9th Circuit and the 6th Circuit, which have held that pesticide applications in, over, or near waters of the U.S. require a CWA permit. In the case of the 6th Circuit case [ National Cotton Council of America v. EPA ], which had voided a 2006 EPA rule...

Atrazine is being subjected to a reevaluation since prior EPA studies during the reregistration process appear to have ignored hormone disruption and exposure studies

Atrazine, a triazine herbicide, stops pre- and post-emergent weeds by inhibiting electron transport, ultimately blocking photosynthesis. [More about the quantum mechanical properties of photosynthesis will be noted in a subsequent blog.] EPA reexamined data on the herbicide's putative toxicity four...

The herbicide Atrazine has estrogenic effects and interferes with metamorphosis of frogs

Prior posts have noted various theories, and the support for such, related to the decreasing presence of frogs in riparian habitats. These have included various pesticides and infections from viruses and fungi. Now, Atrazine joins the parade of possibilities. Past research reports have noted evidence...

Amphibians face threats from chemicals across the landscape

Numerous prior posts have noted various theories and evidence for the reduction in number of frogs found in various environments. Taking a step back from focusing on agricultural lands and practices, some researchers are surveying the presence of frogs, including intersex frogs (those with both male...

Honeybees spread viruses to wild pollinators

Honeybees spread viruses to wild pollinators Numerous prior posts have looked at the evidence, pro and con, for various theories and studies of honeybee colony collapse. From stress to food sources to pesticides, the evidence has been less than compelling. One thesis that arose early and still seems...

Three new studies conclude that prenatal pesticide exposure lowers IQ

Before noting the studies, I should note that I am very skeptical about what it is that IQ tests measure, and whether they are measuring it accurately. Personally, I find the thesis that there are many types of intelligence to be more persuasive, but then I do not hold my self out as an expert on measuring...

Parkinson's may be caused by the same bacterium that causes ulcers, new animal model studies suggest

The cause of Parkinson's Disease is unknown. To date, many experts have suggested that it may have a genetic origin; see http://www.webmd.com/parkinsons-disease/parkinsons-causes . Other experts point to toxins that may selectively destroy the dopaminergic neurons, thereby causing Parkinson's...

Widespread use of herbicides create immunity and resistance in weedy plants

Prior posts have noted that a wide variety of substances, including hazardous substances, can act as selection factors in fostering "evolution" amongst impacted organisms. Now, researchers have found that many weeds, including some of significant economic importance because of the crops impacted...
