Global Threats: Children’s Exposure to Toxic Pesticides
By Roberta Attanasio In 2012, the American Academy of Pediatrics (AAP) released a policy statement to outline the harmful effects of pesticides in children, and to make recommendations on how to reduce exposure. According to the statement, prenatal and early childhood exposure to pesticides is associated with pediatric cancers, decreased cognitive function, and behavioral problems. In addition, the statement pointed out that recognizing and reducing children’s exposure to pesticides requires improved medical training, public health tracking, and regulatory approaches, and made recommendations on specific actions that should be taken to decrease such exposure. Despite the recognition of the dangers associated with pesticide use, and the AAP recommendations on limiting children’s…

Neonicotinoid Pesticides: Bad for Bees, Bad for Many Other Species
By Roberta Attanasio Do neonicotinoid pesticides harm bees? According to scientific evidence, the answer is “yes”. Indeed, scientific evidence for the toxic effects of neonicotinoid pesticides on bees is accumulating at an increasing pace. And, on the basis of scientific evidence, the European Commission banned in 2013 the use of three neonicotinoids — clothianidin, imidacloprid and thiamethoxam — on flowering plants. The ban was motivated by findings from the European Food Safety Authority (EFSA); these findings were based on the evaluation of the scientific studies available at the time. Now, a report from the European Academies Science Advisory Council (EASAC) emphasizes that bees are not the only species affected by…

Global Threats: Contamination of Surface Waters by Agricultural Insecticides
By Roberta Attanasio The use of agricultural insecticides — toxic substances developed to target and kill insects that damage crops — has sparked controversy since the dawn of the “chemical age”, which started in the 1950s. The benefits of agricultural insecticides — for example, increased food production — are undeniable. Unfortunately, along with benefits, there are considerable unwanted effects. Ideally, insecticides must be lethal to the target insects, but not to non-target species. However, these toxic substances do not target only insects — they target many more organisms, including man. Thus, the toxic brew of agricultural insecticides threatens the ecological integrity of aquatic and terrestrial ecosystems. Indeed, agricultural systems play a…
