Problems that rank relatively high in cancer and non-cancer health risks but low in ecological and welfare risks include hazardous air pollutants, indoor radon, indoor air pollution other than radon, pesticide application, exposure to consumer products, and worker exposures to chemicals... 

All decisions involve tradeoffs. Does the benefit of increased food product ion outweigh possible health risks of a pesticide Do the beneficial effects of a new drug outweigh a potentially dangerous side effect in a small fraction of users The answers are rarely obvious, but we should at least try to base our responses on facts. 

Cosmetic Standards. Over the last two decades, the U.S. Food and Drug Administration (FDA) has been lowering the tolerance levels for Insects and insect parts allowed in and on fresh and processed foods (14). Concurrently consumers have sought "more perfect," pest-free produce. To achieve this, farmers have Increased the quantities of pesticide they applied to crops. Although the presence of small amounts of insect parts in such products as catsup and apple sauce, or blemishes on oranges pose no health risk, these stringent standards have stood for many years. 

Information on exposure levels is fundamental for the assessment and management of health risks related to occupational and environmental exposure to pesticides. Biological monitoring is a primary tool for exposure evaluation,... 

There is a growing need to better characterize the health risk related to occupational and environmental exposure to pesticides. Risk characterization is a basic step in the assessment and management of the health risks related to chemicals (Tordoir and Maroni, 1994). Evaluation of exposure, which may be performed through environmental and biological monitoring, is a fundamental component of risk assessment. Biomarkers are useful tools that may be used in risk assessment to confirm exposure or to quantify it by estimating the internal dose. Besides their use in risk assessment, biomarkers also represent a fundamental tool to improve the effectiveness of medical and epidemiological surveillance.

Membrane processes, such as hyperfiltration, can also reduce the health risks caused by the presence of pollutants such as pesticides, heavy metals, endocrine disrupters, pathogens and viruses. This is especially important in case where human beings can get in contact with reclaimed water. 

The EPA does consider health criteria when determining whether to approve or deny a manufacturer s petition to have a tolerance established. Human health risk assessment practices consider potential human exposure from all registered (and proposed) uses of the pesticide, and if the risk is deemed excessive, the EPA will deny the tolerance petition. In cases where the risks are deemed acceptable, the EPA will establish tolerances, as described in the previous paragraphs.

Insecticide, used mostly to protect from diseases spread by insects. Also a byproduct in the production of dicofol, another insecticide.

Chapter 5 of the document reviews the UFs used by UK Government departments, agencies, and their advisory committees in human health risk assessment. Default values for UFs are provided in Table 3 in the UK document with the factors separated into four classes (1) animal-to-human factor, (2) human variability factor, (3) quality or quantity of data factor, and (4) severity of effect factor. The following chemical sectors are addressed food additives and contaminants, pesticides and biocides, air pollutants, drinking water contaminants, soil contaminants, consumer products and cosmetics, veterinary products, human medicines, medical devices, and industrial chemicals. 

We conclude by illustrating how our understanding of these chemical processes in our clean and polluted troposphere and stratosphere plays a crucial role in generating the exposure portions of scientific health risk assessments. Such assessments provide the foundation for sound, health-protective and cost-effective strategies for the control of tropospheric ozone, particles, acids, and a spectrum of hazardous air pollutants (including carcinogens and pesticides)—as well as for the mitigation of stratospheric ozone depletion. 

Consumers can easily calculate the benefits of chemical use. Farmers compufe how pesticides increase crop yields, and people appreci-afe fhe facf fhaf chlorination produces bacferia-free water. It is more difficult to determine the costs of chemical use because, in addition to a commodity s market price, there are less obvious costs, such as increased health risks. 

Although confusing, it is also correct to note that potential human health risks are considered before a tolerance is established. The EPA will perform a risk assessment of the potential dietary risk to consumers from exposure to the pesticide from all registered (and proposed) uses of the pesticide. If such a risk is determined to be excessive, the EPA will deny the manufacturer s petition to establish a tolerance. If the level of risk is not considered to be of concern, the...
