Poisonings is an up- date and expansion of the 1989 fourth edition. The Office of Pesticide Pro- grams of the United States Environmental Protection Agency has sponsored the series since 1973. The purpose of the manual is to provide health profes- sionals with recently available information on the health hazards of pesticides currently in use, and current consensus recommendations for management of poisonings and injuries caused by them. Pesticide poisoning is a commonly under-diagnosed illness in America to- day. Despite recommendations by the Institute of Medicine and others urging the integration of environmental medicine into medical education, health care providers generally receive a very limited amount of training in occupational and environmental health, and in pesticide-related illnesses, in particular.1 The updating of this manual is part of a larger initiative of the U.S. Environmental Protection Agency, in conjunction with numerous

  • What Is the Difference Between Pesticides, Insecticides and Herbicides? Pesticide Effects on Food Production
    What is the Difference Between Pesticides, Insecticides and Herbicides? Pesticides are chemicals that may be used to kill fungus, bacteria, insects, plant diseases, snails, slugs, or weeds among others. These chemicals can work by ingestion or by touch and death may occur immediately or over a long period of time. Insecticides are a type of pesticide that is used to specifically target and kill insects. Some insecticides include snail bait, ant killer, and wasp killer. Herbicides are used to kill undesirable plants or “weeds”. Some herbicides will kill all the plants they touch, while others are designed to target one species. Pesticide Effects on Food Production As the human population continues to grow, more and more crops are needed to meet this growing demand. This has increased the use of pesticides to increase crop yield per acre. For example, many farmers will plant a field with Soybeans and apply two doses of Roundup throughout the growing year to remove all other plants and prepare the field for next year’s crop. The Roundup is applied twice through the growing season to kill everything except the soybeans, which are modified to be pesticide resistant. After the soybeans are harvested, there is little vegetative cover on the field creating potential erosion issues for the reason that another crop can easily be planted. With this method, hundreds of gallons of chemicals are introduced into the environment every year. All these chemicals affect wildlife, insects, water quality and air quality. One greatly affected “good” insect are bees. Bees play a significant role in the pollination of the foods that we eat.

    Material Safety Data Sheet DANITOL 2.4 EC (WARNING Statement) This Material Safety Data Sheet (MSDS) serves different purposes than and DOES NOT REPLACE OR MODIFY THE EPA-APPROVED PRODUCT LABELING (attached to and accompanying the product container). This MSDS provides important health, safety, and environmental information for employers, employees, emergency responders and others handling large quantities of the product in activities generally other than product use, while the labeling provides that information specifically for product use in the ordinary course. Use, storage and disposal of pesticide products is regulated by the EPA under the authority of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) through the product labeling. All necessary and appropriate precautionary, use, and storage, and disposal information is set forth on that labeling. It is a violation of federal law to use a pesticide product in any manner not prescribed on the EPA-approved label. 1.

A strict distinction between these materials is not always possible, and also a generally accepted terminology is lacking. However, research on both materials is increasingly overlapping: sorption and remediation are the domain of activated carbon, which nowadays is also addressed by studies on biochar. Thus, awareness of both fields of research and knowledge about the distinction of biochar and activated carbon is necessary for designing novel research on pyrogenic carbonaceous materials. Here, we describe the dividing ranges and common grounds of biochar, activated carbon and other pyrogenic carbonaceous materials such as charcoal based on their history, definition and production technologies.

  • Historical Use of Lead Arsenate and Survey of Soil Residues in Former Apple Orchards in Virginia
    HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA by Therese Nowak Schooley Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN LIFE SCIENCES in Entomology Michael J. Weaver, Chair Donald E. Mullins, Co-Chair Matthew J. Eick May 4, 2006 Blacksburg, Virginia Keywords: arsenic, lead, lead arsenate, orchards, soil residues, historical pesticides HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA Therese Nowak Schooley Abstract Inorganic pesticides including natural chemicals such as arsenic, copper, lead, and sulfur have been used extensively to control pests in agriculture. Lead arsenate (PbHAsO4) was first used in apple orchards in the late 1890’s to combat the codling moth, Cydia pomonella (Linnaeus). The affordable and persistent pesticide was applied in ever increasing amounts for the next half century. The persistence in the environment in addition to the heavy applications during the early 1900’s may have led to many of the current and former orchards in this country being contaminated. In this study, soil samples were taken from several apple orchards across the state, ranging from Southwest to Northern Virginia and were analyzed for arsenic and lead. Based on naturally occurring background levels and standards set by other states, two orchards sampled in this study were found to have very high levels of arsenic and lead in the soil, Snead Farm and Mint Spring Recreational Park. Average arsenic levels at Mint Spring Recreational Park and Snead Farm were found to be 65.2 ppm and 107.6 ppm, respectively.
