Neonicotinoid pesticides and parasites together negatively affect bumble bees

Feb 11, 2015

As bee populations decline, scientists are directing their research to understand what factors are negatively affecting bee health and what can be done to help them. Because of the large role that the European domestic honey bee plays in crop pollination, particularly on expansive farms, the majority of research has been focused on managed colonies. […]

Eating organic reduces pesticide exposure

Feb 05, 2015

A recent study published in Environmental Health Perspectives has confirmed that choosing organic does, in fact, reduce consumer exposure to pesticides. The study aimed to (1) estimate long-term dietary exposure to organophosphate pesticide residues for individuals, (2) check the accuracy of the estimates and (3) determine whether choosing organic fruits and vegetables lowered pesticide exposure. […]

Prenatal exposure to phthalates linked to lowered IQ in children

Feb 05, 2015

A recent study published in the Journal PLOS ONE has found an association between maternal exposure to phthalates—chemicals commonly found in plastics and personal care products—and lowered IQ in their seven-year-old children. Previous studies had found that phthalate exposure in pregnant women has negative effects on their children. For instance, prenatal phthalate exposure was associated […]

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 […]
