(Beyond Pesticides, May 27, 2010) A new report showcases the pitfalls of the U.S. Green Building Council’s LEED certification program in regards to protecting human health from environmental hazards. The report, “LEED Certification: Where Energy Efficiency Collides With Human Health,” put out by Environment and Human Health, Inc. (EHHI), warns that the LEED certification gives a false impression of a healthy and safe building environment and offers recommendations for the program to become more protective of human health. EHHI found that LEED standards have been incorporated into many federal, state and local laws, and many other corporations and other institutions have adopted LEED standards as well. Although this has encouraged energy efficiency in buildings, according John Wargo, Ph.D., lead author of the study and professor of Risk Analysis and Environmental Policy at Yale University, it has been implemented without fully understanding that energy conservation efforts often reduce the exchange of indoor and outdoor air, which can cause synthetic chemicals to concentrate within buildings. “Tighter buildings often concentrate chemicals released from building materials, cleaning supplies, fuel combustion, pesticides and other hazardous substances,” he said. Energy efficiency is given a high priority over health. The report found that about four times as […]

(Beyond Pesticides, November 12, 2009) Scientists from McMaster University in Hamilton, Ontario have developed a dipstick test that can detect minute amounts of toxins and pesticides in foodstuffs that is slated to be less costly than current pesticide testing methods and can produce results within minutes. Their paper-strip test produces results in minutes rather than hours by means of an easy-to-read color-change. Published in the November 1 issue of the American Chemical Society’s Analytical Chemistry, a semi-monthly journal: “Reagentless Bidirectional Lateral Flow Bioactive Paper Sensors for Detection of Pesticides in Beverage and Food Samples,” study author, John Brennan, PhD, and colleagues note that conventional tests for detecting pesticides tend to use expensive and complex equipment and in some cases can take several hours to produce results. They cite a growing need for cheaper, more convenient, and more eco-friendly tests for pesticides, particularly in the food industry. A 10 cm-long bioactive paper-based solid-phase biosensor was developed to detect acetylcholinesterase (AChE) inhibitors, including organophosphate pesticides. The researchers tested this sensor using food and beverage samples intentionally contaminated with common pesticides. The strip accurately detected trace amounts of the chemicals within five minutes, according to the scientists. The test strip changes color shades […]

(Beyond Pesticides, October 20, 2009) The U.S. Department of Agriculture (USDA) and the Environmental Protection Agency (EPA) are asking farmers to use coal ash to grow their crops, despite a paucity of research on possible risks, according to documents released October 15, 2009 by Public Employees for Environmental Responsibility (PEER). USDA endorses use of coal combustion wastes by farmers “for crop production,” while acknowledging uncertainty on the extent to which “toxic elements” are absorbed into produce entering the market. Beyond Pesticides points out that coal ash is just one of many toxic products “recycled” into fertilizer and encourages people to avoid chemical fertilizers all together in favor of compost and other organic methods. This month, USDA enters the final year of a three-year partnership with EPA as part of a larger effort by the American Coal Ash Association, the Electric Power Research Institute and others to “promote appropriate increased use of” coal ash in agriculture. The implementing Memorandum of Understanding obliges USDA to generate “documentation of the effectiveness, safety and environmental benefits, including bioavailability of trace elements such as mercury, arsenic and selenium”¦to satisfy the concerns of producers, generators, regulators and the public.” According to EPA, agriculture annually uses more […]
