Pesticides Spark Broad Biodiversity Loss

Sep 27, 2013

A study published recently in the Proceedings of the National Academy of Science found that agricultural pesticides have been linked to widespread invertebrate biodiversity loss. The researchers looked at the effects of pesticide use on the regional biodiversity of stream invertebrates, such as mayflies and dragonflies, in Europe and Australia, and found up to 42% fewer species [...]

The environmental risks of neonicotinoid insecticides

Sep 25, 2013

A new study published in the Journal of Applied Ecology that reviews the current scientific evidence on neonicotinoids found that 90% of neonicotinoids persist in soils, where they accumulate and leach into waterways.  Neonicotinoids are neurotoxins that are highly toxic to most insects, and are one of the most commonly used insecticides in the world.  The residues [...]

Pesticides drift and vitalization could result in widespread contamination

Sep 23, 2013

A recent article published in Atmospheric Environment shows that the pesticide endosulfan is able to move long distances through the air.  Endosulfan is one of the most toxic pesticides in current use, and is responsible for multiple instances of fatal poisoning.  It acts as an endocrine disruptor and can cause reproductive and developmental damage to [...]

Pesticides used on conventional bananas found in caimans

Sep 19, 2013

A new study published in Environmental Toxicology and Chemistry found pesticide contamination in Costa Rican caiman blood. Researchers examined 14 adult caiman and found levels of nine pesticides in their blood samples. All nine of the detected pesticides were insecticides, and seven were classified as Persistent Organic Pollutants banned under the 2011 Stockholm Convention. The [...]

Persistent organic pollutants found in the Tibetan Plateau

Sep 14, 2013

A new study published in Environmental Science & Technology shows that persistent organic pollutants (POPs) are present even in the pristine Tibetan Plateau.  POPs are organic compounds that are resistant to environmental degradation, and include such pesticides as DDT, aldrin, and chlordane.  Although these chemicals have been banned in many areas, their long life prevents [...]

Algal blooms in Lake Erie will continue without decreased fertilizer runoff

Sep 13, 2013

A recent study published in the Proceedings of the National Academy of Sciences sheds some light on the record-breaking algal bloom observed in Lake Erie in 2011, and makes some frightening predictions for the future.  The research, led by Dr. Anna Michalak of the Carnegie Institute for Science, shows that phosphorus-laden fertilizer runoff from conventional [...]

Organic milk production is less harmful to the land

Sep 03, 2013

Researchers out of Sweden have examined the land use impacts of producing organic versus conventional dairy, and found that organic dairy is more environmentally friendly. The study, published recently in The International Journal of Life Cycle Assessment, examined several environmental health markers, including plant species richness and regeneration times of ecosystems to determine land use [...]

Roundup Ready crops may be creating super-weeds

Aug 26, 2013

A recent study published in New Phytologist found that glyphosate-resistant crops that cross with closely related wild weeds could confer a fitness advantage to these weeds, even in areas where glyphosate (the active ingredient in Roundup) is not being used. Researchers crossed glyphosate-resistant rice with their weedy relatives to examine the performance of the hybrids [...]

The importance of monitoring harm of GMOs on butterfly populations

Aug 24, 2013

Researchers in Europe have published a new study explaining the importance of and detailing the methods for how to monitor adverse effects on butterflies and moths from genetically modified (GM) crops. Butterflies and moths were the first biological indicators considered for GM crop monitoring because their populations are sensitive to many environmental changes. Over the [...]

Farm fertilizer runoff contributing to Dead Zone

Aug 22, 2013

Excess nitrogen is impacting Mississippi River and worsening the Gulf of Mexico’s Dead Zone, according to researchers studying the watershed of the Cedar and Iowa rivers. These scientists have found record levels of nitrogen in the watershed, driven by a combination of drought from last year and high rainfalls from this spring. Nitrogen is making [...]
