Nanomaterials interact with agricultural pesticides, increasing toxicity to fish

Feb 01, 2015

Fish populations are exposed to a large number of environmental pollutants that run off from agricultural, industrial and urban land. As technology progresses, so do the number of new pollutants in our environment. A new study published in Ecotoxicology and Environmental Safety has found that carbon nanotubes—a type of nanomaterial used for cleaning purification in […]

Frogs and their wetland habitats in Iowa are contaminated with agricultural pesticides

Jan 27, 2015

Amphibian populations in the United States and around the world have been declining due to habitat degradation and loss. Now, a new study, published in Science of the Total Environment, has found that frogs found in Iowa wetlands are accumulating a large number of different pesticides in their tissues, including up to eight different fungicides, […]

Organochlorine pesticides in South African catfish pose cancer risk when consumed by humans

Jan 23, 2015

A recent study published in Chemosphere found that catfish collected from multiple freshwater sites in South Africa contained organochlorine pesticide residues above acceptable levels for cancer risk and hazard index risk for human consumption. Scientists collected fish from three fresh water impoundments, and analyzed their muscle tissue for organochlorine pesticides. They then calculated a human […]

High levels of pesticide exposure in pregnant women in Costa Rica

Dec 25, 2014

  A recent study published in Environmental Health Perspectives has found high levels of the fungicide mancozeb in pregnant women living near banana plantations in Costa Rica. Mancozeb is aerially applied to bananas grown primarily for export to the United States in order to prevent fungal diseases. While mancozeb has relatively low toxicity to humans, […]

Neonicotinoid pesticide use leads to increased crop damage by slugs

Dec 23, 2014

  A recent study published in the Journal of Applied Ecology found that the use of neonicotinoid pesticides in soybean crops reduced yields by indirectly increasing crop damage by slugs, a tenacious crop pest. Researchers found that exposure to neonicotinoids did not have a negative effect on slugs, likely because neonicotinoids are specialized to affect […]

Organic cotton is better for the environment than conventional cotton

Dec 18, 2014

  The Textile Exchange recently published a life cycle assessment (LSA) for organic cotton demonstrating that it is more environmentally friendly than conventional cotton.  A LSA which is also sometimes referred to as a ‘cradle to grave’ assessment, is a study designed to quantify the complete environmental inputs and outputs associated with a particular commodity […]

Insects visit flowers more in organic vineyard than conventional ones

Dec 16, 2014

  A recent study published in Animal Conservation found that there were more insect-flower interactions in organic vineyards when compared to conventionally managed vineyards. Researchers recorded the number of times insects came in contact with flowers in plots established in organic and conventional vineyards in South Africa. While they found that organic and conventional vineyards […]

Alternative flame retardant increases fat cells and decreases bone cells

Dec 11, 2014

  The flame retardants known as pentaBDEs were phased out in 2004 due to health concerns that created a market for new alternatives. Firemaster*500 has largely filled this gap. However, recent research has suggested that exposure to the flame retardant is linked to a variety of problems in rats including increased anxiety, obesity and early […]

Yield gap between organic and conventional farming lower than previously thought

Dec 10, 2014

  A new study published in the Journal Proceedings of the Royal Society Biology has found that the yields of organic crops are higher than previously thought, particularly when organic farmers use environmentally friendly farming techniques. Researchers from the University of California, Berkeley, carried out the largest meta-analysis comparison of organic and conventional crop yields […]

Bt pesticide resistance in the Armyworm

Dec 09, 2014

  Genetically modified corn containing Bt has been used successfully in the United States for the last 18 years to fend off the migratory armyworm, a destructive pest. Now, a study published in the scientific journal PLOS One has found that populations of armyworms in North Carolina and Florida are resistant to the Cry1F protein […]
