Book Description
This paper investigates historical trends in pollutant loadings to Lake Erie. The first of two sections of this report analyzes information on the amount of sediments delivered to Lake Erie and discusses historical trends in sediment yield. There are two primary sources of data: (1) measurements of suspended sediment load made in some of the tributary rivers and (2) analyses of shoreline erosion and sedimentation rates in Lake Erie. These lead to a subsequent analysis of the sediment budget. Since the loading of contaminants to the lake is manifested by sedimentation, results are presented of analyses of contamination inputs from bottom coring. Trends in precipitation, runoff, and lake levels have been analyzed and are presented followed by the calculation and tabulation of the average surface water runoff to Lake Erie. The second section of the report deals primarily with the sources and inputs of the two nutrients, phosphorus and nitrogen, to Lake Erie. There is little specific information on those inputs, and, therefore, information has been assembled from other locations on the sources of these nutrients. The historical growth in population in the Lake Erie Basin has also been traced.

Book Description
Persistent Organic Pollutants (POPs) continue to be the subject of concern amongst the public, as well as the scientific and policy-making communities. These concerns are exemplified by the international efforts co-ordinated by the United Nations' Environment Programme and the +Economic Commission for Europe. Whilst the ultimate origin of this concern is the adverse effects of persistent organic pollutants in both humans and wildlife, there are other factors involved. In particular, whilst ambient concentrations of POPs in air and water present little direct hazard via inhalation and ingestion respectively, their propensity for transfer through the food chain means that species at the top of the ecological pyramid - including humans - can be exposed to concentrations of concern via their diet. Furthermore, their ability to undergo long-range atmospheric transport means that they represent a truly cross-boundary problem for mankind. Persistent Organic Pollutants focuses on the sources, atmospheric behaviour, terrestrial and aquatic food chain transfer, and human exposure and fate aspects of this important class of chemicals. Other topical issues are addressed, namely: temporal trends in contamination; their transport to polar regions; and the significance of the former Warsaw Pact nations of Central and Eastern Europe as both a global reservoir and source of POPs. Whilst the main focus is on PCDD/Fs, PCBs, and PAH; other organochlorine POPs such as DDT, lindane, and dieldrin are covered. Persistent Organic Pollutants also provides up-to-date, detailed, and authoritative coverage required by academics, environmental consultants, and policy-makers. Sufficient introductory material is also included to be of relevance to final year undergraduates, Masters and PhD students in Environmental Science/Chemistry.
