Standard Practice for Selecting and Constructing Exposure Scenarios for Assessment of Exposures to Alkyd and Latex Interior Paints

Importancia y uso:

5.1 Increasing attention is being paid to human exposure to airborne chemicals from products or materials used indoors, for two reasons:

5.1.1 Individuals spend substantial fractions of their time indoors.

5.1.2 Such exposures can occur repeatedly throughout one’s lifetime.

5.2 The primary objectives of this practice are as follows:

5.2.1 To list the elements that need to be considered in developing a scenario to describe how exposure occurs to chemicals emitted from alkyd or latex interior paints.

5.2.2 To discuss procedures and alternatives for choosing and describing these elements.

5.3 Elements of an exposure scenario, in turn, are used to inform a subsequent step of estimating exposures through monitoring studies or computer modeling exercises.

5.4 Once exposures have been estimated, the results can be used to assess the potential impacts of a specific paint formulation on the health of exposed individuals, or to compare the relative impacts of alternative formulations.

5.5 Estimation of exposures, or comparisons of estimated exposures across alternative paint formulations, can lead to development of environmentally preferable products by minimizing adverse health effects for exposed individuals.
