||The report provides an interim assessment of toxic substance loadings from the fall lines of three major tributaries, Susquehanna, Potomac and James Rivers, to the Chesapeake Bay. Results from the first six months of a one year sampling program conducted from March, 1992 to September, 1992 are described. Loadings are provided for trace metals; synthetic organic compounds; organonitrogen, organophosphorus, and organochlorine pesticides; polychlorinated biphenyl congeners; and polycyclic aromatic hydrocarbons. The program included sampling during both base and storm flow conditions. A key component of the report is the comparison of ultra clean versus standard U.S. Geological Survey protocol collection techniques for trace metals and organics.
