Utility Sprays Right-of-Way and Nearly Kills Centuries-Old Grape Vine

(Beyond Pesticides, August 5, 2010) A 400-year old large old grape vine considered to be the nation’s oldest in Manteo, North Carolina and known lovingly as “Mother Vine,” is slowly recovering from a powerful dose of herbicide sprayed by a utility company. The Virginia-based Dominion Power Company contracted Lewis Tree Service to spray power poles along the roads in the Manteo in May. The herbicide they used, Garlon3A, was accidentally sprayed on a tiny shoot from the vine that had grown a few feet up a pole on 84-year old Jack Wilson’s property. Unaware of the recent herbicide spraying by the utility power company, he noticed various brown, dead sections that began to appear in the plant in May. Not only did the vine suffer, but about 10 feet of a nearby hedge died, along with three limbs of a large pecan tree that had to be trimmed. The active ingredient in Garlon 3A, a Dow Chemical product, is triclopyr. It is a systemic herbicide which means that the poison spreads from the ends of the vine back toward the root. As a broadleaf weed killer, triclopyr is frequently used along rights-of-way and on industrial sites. In laboratory tests, triclopyr […]

Risk Assessment Flaw Downplays Insecticide’s Link to Bee Kills

(Beyond Pesticides, August 3, 2010) A new study shows that due to a flaw in standard risk assessments, which consider toxic effects at fixed exposure times, the risks posed by the neonicotinoid pesticides imidacloprid and thiacloprid are likely to be underestimated. The authors believe that minute quantities of imidicloprid may be playing a much larger role in killing bees over extended periods of time than previously thought. The study, “The significance of the Druckrey—Küpfmüller equation for risk assessment””The toxicity of neonicotinoid insecticides to arthropods is reinforced by exposure time,” was published online July 23, 2010 in the journal Toxicology. The authors believe that standard risk assessment calculations underestimate toxicity because they do not accurately account for the interplay of time and level of exposure. According the study: The essence of the Druckrey—Küpfmüller equation states that the total dose required to produce the same effect decreases with decreasing exposure levels, even though the exposure times required to produce the same effect increase with decreasing exposure levels. Druckrey and Küpfmüller inferred that if both receptor binding and the effect are irreversible, exposure time would reinforce the effect. The Druckrey—Küpfmüller equation explains why toxicity may occur after prolonged exposure to very low toxicant […]

Chemical Exposure Linked to Gulf War Veterans’ Illness

(Beyond Pesticides, March 13, 2008) Exposure to certain chemicals, including pesticides and nerve agents, explains the high rates of illness in Persian Gulf War Veterans, according to a new study published in the Proceedings of the National Academy of Sciences. Veterans from the 1990-91 conflict have a higher rate of chronic, multi-symptom health problems than either non-deployed personnel or those deployed elsewhere. Symptoms routinely reported by these veterans include fatigue, muscle or joint pain, memory problems, trouble sleeping, rash and breathing problems. Due to the findings, the study author, Beatrice Golomb, M.D., Ph.D., associate professor of medicine at the University of California, San Diego School of Medicine, warns of the potential risk to civilians exposed to pesticides.“Health issues among Gulf War veterans have been a concern for nearly two decades. Now, enough studies have been conducted, and results shared, to be able to say with considerable confidence that there is a link between chemical exposure and chronic, multi-symptom health problems,” said Dr. Golomb. “Furthermore, the same chemicals affecting Gulf War veterans may be involved in similar cases of unexplained, multi-symptom health problems in the general population.”The study synthesized evidence regarding a class of chemicals known as acetylcholinesterase inhibitors (AchEs), including […]
