Until recently, few papers appeared on the fate of dyes in the environment. But because of the importance of this subject, work is being done primarily by the U.S. Environmental Protection Agency (USEPA) and the Ecological and Toxicological Association of the Dyestuff Manufacturing Industry (ETAD).

Colorimetry. Laboratory data on the persistence of biocides formulated in glutaraldehyde and acrolein are available [1260]. A colorimetric general aldehyde detection method based on m-phenylenediamine was used. Such studies follow the demand for better understanding of ecologic systems in the aspect of environmental protection.

Finally, in the risk characterization step, the PEC/PNEC quotient that defines the risk of the substance in the environment is calculated. If the quotient (PEC/PNEC) is less than 1, the substance do not present risk to the environment. More information is available in the European Commission Technical Guidance Document on Risk Assessment [3] and in the United States Environmental Protection Agency s Guidelines for Ecological Risk Assessment [6]. 

The human and environmental protection goals in EUSES are human populations (workers, consumers, and man exposed via the environment) and ecological systems (micro-organisms in sewage treatment systems, aquatic ecosystems, terrestrial ecosystems, sediment ecosystems, and predators). Repeated dose toxicity, fertility toxicity, maternal toxicity, developmental toxicity, carcinogenic risk, and lifetime cancer risk can be calculated for the cases that literature data is available.

The critical load concept is intended to achieve the maximum economic benefit from the reduction of pollutant emissions since it takes into account the estimates of differing sensitivity of various ecosystems to acid deposition. Thus, this concept is considered to be an alternative to the more expensive BAT (Best Available Technologies) concept (Posch et al., 1996). Critical load calculations and mapping allow the creation of ecological-economic optimization models with a corresponding assessment of minimum financial investments for achieving maximum environmental protection.

Uncertainty analysis is increasingly used in ecological risk assessment and was the subject of an earlier Pellston workshop (Warren-Hicks and Moore 1998). The US Environmental Protection Agency (USEPA) has developed general principles for the use of Monte Carlo methods (USEPA 1997), which provide one of several approaches to incorporating variability and uncertainty in risk assessment. 

Norton (1998) offers one approach from an ecological risk assessor s perspective. Various experts in statistics and risk assessment at the workshop preferred specific terms over others. The majority of the workshop participants were comfortable with distinguishing between uncertainty and variability in a manner that is consistent with US Environmental Protection Agency (USEPA) guidance. Other experts, particularly those associated with bounding analyses (see Chapter 6 of this book), preferred the word incertitude instead of uncertainty based on theoretical considerations associated with the bounding methods discussed in the chapter.
