Abstract
More and more time is
spent on recreational activities, but few risk assessments focus specifically on
these situations and exposure factor data are often scarce. To assess exposure
to contaminants at a public bathing place in an urban environment, we have
compiled literature data, conducted observation studies, and analyzed water and
sediment samples. The levels of anthropogenic contaminants are high in urban
environments and traffic frequently plays an important role. In this study, to
characterize variability and uncertainty, the deterministic exposure
calculations for metal pollutants were supplemented by a probability bounds
analysis for the polycyclic aromatic hydrocarbons (PAH). The results from these
calculations show that oral intake is the major exposure route for metals, while
skin absorption, with present assumptions, is more important for the PAH. The
presently measured levels of contaminants, at this public bathing place, cannot
be anticipated to cause any significant adverse influence on public health. This
assessment methodology is easy to adapt and can be used routinely in other
situations with more heavily contaminated surface sediments and lake water.
