About Information by Country
This program helps OECD governments to co-operate in assessing and reducing the risks of agricultural pesticides (used on farms and gardens) and of biocides (used to sterilise hospital equipment, disinfect swimming pools, and for many other purposes).
What's new A Vision for the Future: A Global Approach to the Regulation of Agricultural Pesticides 28-Apr-2004 OECD countries agree to a ten-year vision for the harmonisation of regulatory approaches for agricultural pesticides (chemical and biological) to facilitate and promote the sharing of work between regulatory authorities. The highlight of this “Vision” is that by 2014, OECD countries will routinely accept dossiers prepared by stakeholders in the OECD format; will routinely exchange "monographs" containing reviews of the data submitted; and will use OECD "monographs" as a basis for independent risk assessments and regulatory decisions for new and existing pesticides.

Characteristics Pesticide Transport and Fate Monitoring in the Environment Methods for Measuring Human Exposure to the Agent ... 5103/5104 Home Monitoring Pesticides in the Environment
Pesticides in the environment can be measured using many different techniques depending upon what medium is being tested and what the point of interest is. Sample collection for pesticide monitoring may range from grab samples out of waterways to the capture of fish or birds to test tissue levels. Most commonly, an area of concern will be monitored on a regular basis. It is possible to monitor soil, water, and air for amounts of pesticide.
Monitoring Soils
Soil properties play a large role in how pesticides are distributed through out the landscape. Soils that are subject to wind erosion can be a concern for airborne pesticides. Soils that allow water to flow through them quickly like sandy soils may be a concern for pesticide leaching which means that the pesticide will move through the soil with water or to a lesser extent through gas exchange. Unless there is reason to believe that unusually high amounts of pesticide exist, such as a chemical spill, soil is not generally monitored on a regular basis.
Monitoring Water
Monitoring Air
Air is also of concern. Studies done in the recent past have found that air contains levels of pesticides that have been used in the past as well as those that are used today. However, several other environmental contaminant and quality issues take priority over pesticides in ambient air (meaning when there is not direct cause to suspect elevated levels of pesticides), and it is not common for air to be monitored regularly for pesticides. Also, rain causes the wet deposition of pesticides so often rain water will be monitored in favor of regular air monitoring because rain can be an indicator of amounts of pesticide in the atmosphere as well as pesticides that are being deposited on land or water bodies.

Kroll examines how Carson justified her three main evaluative premises (or her two controversial ones, concern for human health presumably needing no justification).
Rachel Carson's environmental ethics
This essay by Philip Cafaro discusses several respects in which Rachel Carson's life and work might point the way forward for environmental ethics. First, Carson's frequent criticisms of human attempts to dominate nature suggest important parallels with contemporary ecofeminism. Second, Carson's philosophy of "reverence for life" seems to support the whole spectrum of environmental activism.

Clemson Extension
Before Completing Your Self-Assessment
Your responses to this self-assessment are for YOUR use. Although completing this self-assessment is voluntary, taking a few minutes to respond may help you identify potential areas on your farm that could lead to water quality problems. You may find it useful to involve your spouse and/or children in completing your self-assessment. If you need other help or followup information, contact your county Extension office. Why You Should Be Concerned About Pesticides Although drinking water contamination from pesticides is rare, it is possible under certain conditions. For example, pesticides may enter the ground water that supplies drinking water indirectly, by leaching or moving through the soil, or directly by leaks and spills. Pesticides can enter a drinking water supply by backflow or back-siphonage during pesticide mixing. Pesticides may also enter ground water through a poorly sealed well or an abandoned well. Pesticides applied immediately before a heavy rain may wash into streams or other surface waters and threaten fish and wildlife. For these reasons, do not use pesticides around a drinking water source or other water sources.

EPA and Mosquito Control
Customer Satisfaction Questionnaire Mosquito-borne diseases affect millions of people worldwide each year. In the United States, some species of mosquitoes can transmit diseases such as encephalitis, dengue fever, and malaria to humans, and a variety of diseases to wildlife and domestic animals. To combat mosquitoes and the public health hazards they present, many states and localities have established mosquito control programs. These programs, which are based on surveillance, can include nonchemical forms of prevention and control as well as ground and aerial application of chemical and biological pesticides. The mission of the Environmental Protection Agency (EPA) is to protect human health and the environment. EPA reviews and approves pesticides and their labeling to ensure that the pesticides used to protect public health are applied by methods which minimize the risk of human exposure and adverse health and environmental effects. In relation to mosquito control, the Agency also serves as a source of information about pesticide and non-pesticide controls to address the concerns of the general public, news media, and the state and local agencies dealing with outbreaks of infectious diseases or heavy infestations of mosquitoes. The following documents provide some basic information on mosquito control, safety precautions, and information on insecticides used for mosquito control programs.

Chemical insecticides are a useful tool in the control of insect pests but they are not the only method available. The home-owner has a number of biological and cultural options that, from an environmental and health viewpoint, are more attractive. A rigorously followed pest management program around the home and garden will hold pest populations at a level where pesticides will seldom be required and then only as a last resort. The phrase "pest management" is intended to convey the concept of managing pest populations rather than controlling them. Pest management is a systematic approach to keeping pest populations below the economic/aesthetic injury level. It demands some knowledge of insect life histories and the influence of the physical environment on pest reproduction, survival, and distribution. Much of this information is available from both provincial and federal agriculture departments. Non-chemical pest control should be used, particularly as the initial step. The following list of common home and garden pests and corresponding control methods could form the basis of your own pest management program.

Pesticides
Pesticides are among the most widely used chemicals in the world, and also among the most dangerous to human health. They are a leading cause of poisonings here in Canada and have been estimated to account for thousands deaths each year globally. Pesticides can also have chronic health effects both as sequelae of acute poisonings and from chronic exposure. Many studies have documented adverse health effects on humans. There are several areas of concern. Many of the commonly used household insecticides are organophosphates. These have been linked in many studies to neurological damage in humans. In fact, chlorpyrifos, a pesticide from this class, was recently banned by the EPA in the US a recent review of the science demonstrated that children have been routinely exposed to unsafe levels. There is also convincing evidence that pesticides play a role in human cancers. For example, epidemiologic studies have linked exposure to insecticides in the home to development of brain cancer and leukemia in children. Studies have also documented reproductive abnormalities such as an increased rate of miscarriage in people with chronic exposure to pesticides.

Children do not live and grow in a vacuum. The purity of their food and water, the quality of their air, and the safety of their school and home environments are all important factors that influence their health and development. In childhood, exposure to environmental toxins (poisons) may not only cause immediate (acute) illnesses but may also increase the risk for long-term (chronic) problems. It can even trigger cell damage that eventually leads to cancer Health experts have spent decades trying to determine the full environmental effects of certain toxic chemicals. Environmental scientists, like detectives, must often sort through years of evidence to determine the most likely cause of a particular pattern of symptoms. Sometimes the problem is man-made, like the lead in old paint chips, but sometimes it's as "natural" as a cloud of radon gas. As scientists continue to add to the list of natural and man-made environmental health threats, parents need to expand their own safety checklists for possible toxins in their children's home and school environments. In some cases, simply filtering drinking water or removing old paint on a window frame can be a major step toward protecting a child's health.

When you're grocery shopping, it's easy to find labels and pick foods that help you reduce cholesterol and saturated fat, avoid antibiotics, or steer clear of artificial colors, flavors and sweeteners. But when it comes to pesticides, consumers have been left in the dark. Now there's help. The Shopper's Guide to Pesticides in Produce lists the 12 popular fresh fruits and vegetables that are consistently the most contaminated with pesticides and those 12 fruits and vegetables that consistently have low levels of pesticides. If you are concerned about pesticides in your diet, the handy wallet card can help you choose produce that lowers exposure to pesticides for you and your family. For the most contaminated items, we suggest substituting organically grown produce whenever possible. When this is not an option, we still recommend eating lots of fresh fruits and vegetables but use this guide to buy those that typically have fewer pesticides.

Pest Control
Without some form of pest control, crop and animal losses would be severe, so throughout history farmers have used various means of controlling pests and diseases. The ancient Greeks, for example, used smoke to repel insects and natural poisons such as arsenic to kill them. Pesticides are, by their nature, toxic; they are intended to kill predators and pests (arthopods, usually insects). Disease suppressing agents, such as for fungi, may also be used and often are lumped together with pesticides. Organic farmers use non-manmade pesticides, but some of these are highly toxic; synthetic pesticides were initially seen as a safer alternative to those naturally available. Some synthetic pesticides have been found to be highly toxic or to have persistent effects on ecosystem or human health. Over time pests can become resistant to any pesticide and alternatives are necessary. Considerable research has been conducted to develop safer pesticides, techniques that minimize the amounts of pesticides required, and alternative methods of controlling pests. Integrated Pest Management (IPM) uses various approaches to reduce pesticide use. Biocontrol uses natural predators to control insects and other pests, although there have been cases in which the predator that has been introduced has itself become a pest. Biotechnology has been used to modify plants so they are genetically resistant to insects and to some viruses, reducing the need to apply pesticides to crops. Some concerns have been raised about this method, particularly in Europe and Japan. Efficient, high-yield farming means that more crops can be grown on fewer acres of land, so effective pest control has environmental benefits. The following sections provide information about various means of controlling pests.
