spec: This is not a problem for today 's test . The Lake Winnipeg Action Plan was developed in part from scientific research conducted through the Nutrient Management Strategy and will be updated as studies continue . The goal of this study is the development of a system based on the use of the ligninolytic enzyme Manganese Peroxidase ( MnP ) for the degradation of polycyclic aromatic hydrocarbons ( PAHs ) , of which anthracene was selected as an example . Although minute amounts of polycyclic aromatic hydrocarbons are also adsorbed because of cross-reactivity , strong correlations have been observed with respect to conventional GC / MS methods , thus making this a promising screening method . `` For example , in the United States , women are proportionally underrepresented in the advanced study of many sciences , particularly physical sciences and engineering . What : A congressional briefing to discuss findings of recent studies by the USGS and the City of Austin that identified sealcoating – the black , shiny surface often applied to asphalt pavement – as a significant and previously unrecognized source of extremely elevated concentrations of polycyclic aromatic hydrocarbons ( PAHs ) in streams .
