Dietary exposure to pesticides associated with reduced semen quality

Mar 31, 2015

A new study out of Harvard University has linked dietary exposure to pesticides with lower sperm quantity and quality in men. Three hundred thirty-eight semen samples were collected from 155 men from 2007 – 2012. The diet of each participant was assessed using a dietary survey. The concentration of sperm and level of movement were […]

Herbicides, including glyphosate, increase antibiotic resistance in E. coli and Salmonella

Mar 25, 2015

A new study in mBio, a peer-reviewed journal published by the American Society for Microbiology, suggests that the herbicides dicamba (Kamba), 2,4-dichlorophenoxyacetic acid (2,4-D) and glyphosate (Roundup) induce antibiotic resistance in E. coli and Salmonella bacteria. Researchers subjected bacteria to combinations of different herbicides and antibiotics, including antibiotics commonly used to treat bacterial infections in […]

Organic management in apple orchards increases beneficial fungal diversity in soils

Mar 25, 2015

Arbuscular mycorrhizal fungi (AMF) live in cooperative relationship with many plants. Living in the soil with plant roots, they obtain sugars from the plant and, in return, bring minerals and nutrients from the soil to the plant’s roots and protect the plant from root pathogens and predators found in the soil. Because of the great […]

Exposure to glyphosate “probably causes cancer in humans”

Mar 23, 2015

A new study published by the World Health Organization (WHO) has determined that exposure to glyphosate, one of the primary pesticides used on genetically modified ‘round-up ready’ crops, “probably” causes cancer in humans. Glyphosate is one of the most commonly used herbicides in the world and is found in over 750 different products used on […]

Density of pest insects determines harm from neonicotinoids to beneficial predators

Mar 20, 2015

Neonicotinoid pesticides have been criticized for the harm they may cause to non-herbivore insects such as bees. Now, a growing body of literature suggests that their use may also indirectly harm beneficial insects that prey on insect pests. One recent study published in the scientific journal Crop Protection found that when wheat was treated with […]

Effect of chronic field-realistic exposure to the neonicotinoid, Imidacloprid, on honeybee colony health

Mar 19, 2015

A new study published by PLOS One shows that the neonicotinoid pesticide, imidacloprid, can have subtle negative effects on bee health. The study, conducted by Researchers from the University of Maryland and USDA-ARS conducted a three-year study to determine how imidacloprid levels within hives changed over time and how chronic low-level exposure to the neonicotinoid, imidacloprid […]

Microbial communities in organic soils suppress pathogens

Mar 17, 2015

Organic soils support much higher levels of biodiversity than conventional soils. It has been hypothesized that this abundance of ‘good’ soil organisms works to suppress soil pathogens such as fungi or bacteria that attack plant roots. A recent study published in the journal Applied Soil Ecology tested to see whether the soil pathogen flax wilt […]

Exposure to very low levels of neonicotinoids negatively affects bumblebee brains

Mar 13, 2015

A recent study published in the journal of the Federation of American Societies for Experimental Biology has found further support that exposure to very low levels of neonicotinoid pesticides, comparable to what is found in nectar and pollen from neonicotinoid-treated crops, is sufficient to harm bees. Researchers carried out a combination of laboratory and field […]

Effects of pre- and post-natal exposure to flame retardants in children

Mar 10, 2015

  Polybrominated diphenyl ethers (PBDEs) are flame retardants that were commonly used to treat household items such as furniture and infant products. In 2004, they were banned from use in household items because of their actions as human endocrine disruptors. Unfortunately, people are still frequently exposed to PBDEs by way of dust in homes that […]

Early organophosphate exposure linked to respiratory illness in children

Mar 03, 2015

Organophosphates are one of the most commonly used pesticides in the world. Although they are now restricted for residential use due to human toxicity, they are still widely used in agriculture. A recent study published in Environmental Health Perspectives has found a slight association between early exposure to organophosphate pesticides and respiratory symptoms consistent with […]
