"Access" is an indexing, abstracting, and information retrieval service that covers published and non-print information on environmental pollution, conservation, and related fields. It provides an overview of the environmental reporting of more than 1000 scholarly, scientific, industrial, technical, and general periodicals and major newspapers; important environmental radio and television programming, films and filmstrips, books, corporate publications, and major conference publications. Introductory pages explain the Access system, the Ecology Forum, the microfiche retrieval system, and significant information appearing in the issue. The Main Entry section contains document abstracts related to: air pollution, chemical and biological contamination, energy, environmental action, environmental design, food, international aspects, land use and misuse, noise pollution, non-renewable resources, oceans and estuaries, population planning and control, radiological contamination, recreation, renewable resources, solid wastes, transportation, water pollution, weather, modification and geophysical change, and wildlife. Special emphasis in this issue is on papers, proceedings, and comments from the U.N. Conference on the Human Environment. Additional sections deal with significant environmental entries from the Federal Register, current environment-related conferences, and subject, industry, and author indexes. (BL)
