Major consequences of present and additional environmental quantities of DDT pesticide are predictable by mathematical models of transport, accumulation and concentration mechanisms in the Wisconsin regional ecosystem. High solubility and stability produce increased DDT concentrations at high organism trophic levels within world biosphere…

With a spotlight upon current agricultural difficulties and environmental dilemmas, this paper considers both the extant and potential applications of genetic engineering with respect to crop production. The nonagricultural factors most likely to sway the impact of this emergent technology upon future crop production are illustrated. (JJK)

Discussed are the sources, and harmful effects of methylmercury. Research on this problem is reviewed. Suggestions to help anglers reduce their mercury consumption from fish they catch are provided. (CW)

Purpose: This paper examines individual, family, and neighborhood level predictors of resilience in adolescence and young adulthood and describes changes in resilience over time from adolescence to young adulthood in abused and neglected children grown up. Method: We use documented cases of childhood physical and sexual abuse and neglect (n = 676)…

Nonsmokers repeatedly breathe smoke-polluted air in various settings, despite the evidence demonstrating the deleterious consequences upon such passive smokers. The extent of exposure to environmental irritants during a 17-day baseline period was tested, and the efficacy of two simple behavioral strategies in reducing smoke were documented…

This revised and updated book is written to inform the citizens on the nature, causes, and effects of air pollution. It is written in terms familiar to the layman with the purpose of providing knowledge and motivation to spur community action on clean air policies. Numerous charts and drawings are provided to support discussion of air pollution…

Study found that social density is more strongly related to crowding ratings than is spatial density. Predictors of pleasantness include work-play, amount of space, waiting, and percent of people alone or unaccompanied. (Author/MA)

Social anthropological theory is used to analyze the relationship of education to sociocultural change resulting from the interaction of the local ecological system and national influences in two rural regions of the Chiapas. (Author/AM)

Tests 242 newborns exposed prenatally to low levels of polychlorinated biphenyls from maternal consumption of contaminated lake fish. The Brazelton Neonate Scale was used to assess behavioral outcomes. Contaminated fish consumption predicted motoric immaturity, poorer labeling of states, a greater amount of startle, and abnormally weak…

Environmental problems do not stop at state boundaries; they reach beyond local or national jurisdictions and require international control. Problems concerning air quality, water pollution, and indirect pollution are discussed. Environmental legislation can have a significant impact. (RM)

A discussion of man's role in controlling the environment is presented. An optimistic picture of the future is given with regard to this control. (JP)

Systematic study disclosed unexpected sources and statistics of pollution problems unsuspected by this state university. (IR)

A large number of animals are becoming extinct at an alarming rate due to ecosystem alteration, hunting, introduction of species, predator and pest control, capture of animals for legitimate and illegal purposes and pollution. There is concern man may not be able to survive in a world void of diversity. (BT)

This document reviews the process by which the cost benefits of using LANDSAT on an operational basis in the surveillance of lake eutrophication was established. The program identified the information needs of users conducting on-going water quality programs, transformed these needs into remote sensing requirements, produced LANDSAT maps and data…
