The Directive distinguishes between existing, planned and emergency exposure situations.
Less positive, however, are noise exposure situations during leisure time activities.
According to the ICRP [14] the principle of optimisation of protection applies to all exposure situations.
The product life cycle and the product design determine the various environmental and health exposure situations.
Since both regulations aim to protect different water bodies with different exposure situations, ecotoxicological thresholds also are differently calculated.
The results of this study thereby give advice on the proper measurement method in similar exposure situations.
The major advantage of such methods is their easy adaptability to different exposure situations, e.g. when the chemical composition of a biocidal product changes.
Taking into account this new framework, the Directive covers all exposure situations and all categories of exposure, namely occupational, public and medical.
Hence, less-than-lifetime exposure values for shorter than lifetime exposure situations have incorporated additional safety margins to account for this experimental observation (Table 1).
Fabrics are also used for UVR personal protection in outdoor occupational exposure situations, where compliance with recommended exposure limits may be advised.
This indicates that interactive effects observed in an equitoxic experimental design cannot always be simply extrapolated to environmentally realistic exposure situations.
