Human and Ecological Risk Assessment by Dennis J. Paustenbach download in iPad, pdf, ePub
Since it is impractical to study all possible relationships for all possible responses, toxicity research typically focuses on testing for a limited number of adverse effects. In addition, the differences between individuals due to genetics or other factors mean that the hazard may be higher for particular groups, called susceptible populations. Mathematical modeling, which can incorporate more than one effect level i. In practice, each component of the risk assessment e. However, in both cases, ability to anticipate future events and create effective strategies for mitigating them when deemed unacceptable is vital.
Without a potential adverse consequence, there is no hazard. Megaprojects have been shown to be particularly risky in terms of finance, safety, and social and environmental impacts. The exposure route is generally further described as intake taken in through a body opening, e. Clarity - The products from the risk assessment should be readily understood by readers inside and outside of the risk assessment process.
This restricts the range of hazards to be considered. Other individuals may have a lower degree of contact for a shorter period e. The risk associated with no incineration is potential spread of infectious diseases, or even no hospitals.
Documents should be concise, free of jargon, and should use understandable tables, graphs, and equations as needed. This effect is particularly notorious in projects involving multiple stakeholders with different points of view. In some emergencies this may also hold true, with the prepared and trained responses being adequate to manage the situation. There are public health risks, as well as economic costs, associated with all options.
Novel ecosystem Perhaps the most important implication involves our view of human society. Exposure Quantification, aims to determine the amount of a contaminant dose that individuals and populations will receive, either as a contact level e. Some of these are listed here. In these cases estimates must be made of reasonably likely consequences and associated probability of occurrence. The applied dose may be less than the potential dose if the agent is only partly bioavailable.
Human values, wealth, life-styles, resource use, and waste, etc. Finally, the delivered dose is the amount of agent available for interaction with any specific organ or cell. Some of these applications focus instead on addressing problems that cross disciplinary boundaries or transcend those boundaries altogether. The applied dose is the amount of agent at the absorption barrier that is available for absorption. In his publication, Specimen academicum de oeconomia naturae, Linnaeus developed a science that included the economy and polis of nature.
For more information on exposure assessment methods, see the Guidelines for Exposure Assessment. Mathematical or experimental models may provide useful input.
An exposure assessment includes some discussion of the size, nature, and types of human populations exposed to the agent, as well as discussion of the uncertainties in the above information. The first step in risk assessment is to establish the context. This is done by examining the results of the discipline of exposure assessment. Take an assessment of all data that are available or can be gathered through experiments.
