Ultraviolet radiation (UVR) is a naturally occurring stressor to most forms of life. The sole relevant source of this stressor is the sun. The Earth's stratospheric ozone layer reduces the amount of UVR that reaches the Earth's surface. The potential for continued depletion of this ozone layer and environmental changes that increase the penetrance of aquatic habitat, both due to human activities, and the subsequent increase in UVR are global environmental concerns for both humans and ecosystems. An integrated risk assessment provides efficiency in data gathering, analysis and reporting by enabling risk assessors to use the combined knowledge from many disciplines to evaluate overall risk. This report describes the steps and example information that could be used for an integrated risk assessment but is not an actual risk assessment with all its associated calculations and conclusions. It is intended to illustrate the advantages of the integrated risk assessment approach for evaluating adverse effects of a nonchemical stressor.
