Some will remark that our presentation is not complete or that some details are missing. The purpose of this book, however, is not to be complete but to provide a starting point for those who wish to learn about this important area. This book, for example, has a companion text titled Health and Environmental Risk Analysis that extends the topics relevant to risk analysis.

Typical analysis for the neutralization wet process product is given in Table 5. Sodium cyanide is packed in mild steel or fiber dmms and in 1.4 t Flo-bins. Dry sodium cyanide is also shipped in wet-flo tank cars and tmcks of up to 32 t net. At destination, water is circulated through the wet-flo car or trailer to dissolve the dry sodium cyanide at deUvery. This type of shipment reduces freight costs and reduces environmental risks compared with 30% aqueous solution shipment. Safety regulations are imposed by the various shipping lines and by the countries in which cyanide is transported. 

A leader in applying PSA to other parts of the chemical process industry has been the AlChf. s Center for Chemical Process Safety. A major difference between PSA for nuclear power and PSA for chemical processing has been the lack of government regulations that require risk analysis for chemical processes. A primary impetuous has been the Occupational Safety and Health Administration s (OSHA) PSM rule that defines the application of PSA to the chemical industry for ihc proteciion of the public and workers. In addition, the Environmental Protection Agcrii, . (EPA) regulates waste disposal. 

The Chemical Process Industry (CPI) uses various quantitative and qualitative techniques to assess the reliability and risk of process equipment, process systems, and chemical manufacturing operations. These techniques identify the interactions of equipment, systems, and persons that have potentially undesirable consequences. In the case of reliability analyses, the undesirable consequences (e.g., plant shutdown, excessive downtime, or production of off-specification product) are those incidents which reduce system profitability through loss of production and increased maintenance costs. In the case of risk analyses, the primary concerns are human injuries, environmental impacts, and system damage caused by occurrence of fires, explosions, toxic material releases, and related hazards. Quantification of risk in terms of the severity of the consequences and the likelihood of occurrence provides the manager of the system with an important decisionmaking tool. By using the results of a quantitative risk analysis, we are better able to answer such questions as, Which of several candidate systems poses the least risk Are risk reduction modifications necessary and What modifications would be most effective in reducing risk ... 

An enzyme immunoassay technique has been employed for measuring endosulfan and its degradation products (i.e., endosulfan diol, endosulfan sulfate, endosulfan ether, and endosulfan lactone) in water at 3 ppb (Chau and Terry 1972 Musial et al. 1976). However, this technique is not currently in use in environmental residue analysis. Further research into this technique could produce a rapid, rehable, and sensitive method for identifying contaminated areas posing a risk to human health. No additional methods for detecting endosulfan in environmental media appear to be necessary at this time. However, methods for the determination of endosulfan degradation products are needed. 

The comprehensive and detailed assessment of the risks required for a safety-case can only be satisfactorily carried out for major installations with the aid of computer software. Suites of programmes for quantitative risk analysis have been developed over the past decade by consulting firms specializing in safety and environmental protection. Typical of the software available is the SAFETI (Suite for Assessment of Flammability Explosion and Toxic Impact) suite of programs developed by DNV Technica Ltd. These programs were initially developed for the authorities in the Netherlands, as a response to the Seveso Directives of the EU (which requires the development of safety cases and hazard reviews). The programs have subsequently been developed further and extended, and are widely used in the preparation of safety cases see Pitblado el al. (1990). 

First, we investigate some of the regulatory motivations for chronic risk analysis. Next, it is necessary to point up the similarities and differences between acute and chronic risk and delineate the steps in estimating health risks posed by environmental chemicals. Following some illustrations of model structure, we conclude by discussing specific factors in fate analysis that suggest choices of model components. 

Any analysis of risk should recognize these distinctions in all of their essential features. A typical approach to acute risk separates the stochastic nature of discrete causal events from the deterministic consequences which are treated using engineering methods such as mathematical models. Another tool if risk analysis is a risk profile that graphs the probability of occurrence versus the severity of the consequences (e.g., probability, of a fish dying or probability of a person contracting liver cancer either as a result of exposure to a specified environmental contaminant). In a way, this profile shows the functional relationship between the probabilistic and the deterministic parts of the problem by showing probability versus consequences.

For the ecological assessment, risk analysis was based on the traditional PEC/ PNEC ratio (Hazard Quotient) where PEC is the predicted environmental concentration (resulting from chemical analysis) and PNEC the predicted no-effect concentration. Ecological assessment for aquatic species was based on rainbow trout or fathead minnow while terrestrial assessment was based on small rodents like mice rats and rabbits. Exposures associated with HQ<1 were considered negligible.

NOMIRACLE (2004-2009, http //viso.jrc.it/nomiracle/) provided support to the development and improvement of a coherent series of methodologies underpinned by mechanistic understanding, while integrating the risk analysis approaches of environmental and human health. The project delivered understanding of and tools for sound risk assessment, developing a research framework for the description and interpretation of combined stressor effects that leads to the identification of biomarkers and other indicators of cumulative impacts. 

CLL approach and ecosystem, risk analysis. This approach provides insights on assessment and measurement endpoints for ecosystem-level EcoRA since it has a set of environmental criteria to detect the state of ecosystems critical load itself can be treated as a criterion for ecosystem sustainability (Bashkin, 2002). Moreover, one can derive spatial ecosystem risk estimates based on the percentage of ecosystems protected/potentially at risk under the current and predicted level of pollutant loads.
