The Tenth Great Lakes Regional Meeting of the American Chemical Society met to assess current Chemical Research activity in the Great Lakes Basin, and addressed to the various aspects of the theme, Chemistry of the Great Lakes. Research areas reviewed included watershed studies, atmospheric and aquatic studies, and sediment studies. (BT)

Airborne asbestos is analyzed by differential dye adsorption. Quantities can be estimated down to 100 mg. For industrial use, asbestos samples must be separated from interfering minerals by density flotation. (Author/BT)

Gas chromatography can be used to quantitate various gases, complex organic molecules, metals, anions, and pesticides in the lab or in the field. Important advances in gas chromatography and how they directly apply to environmental analyses plus suggestions where they will be of importance to environmental chemists are discussed. (BT)

A Canadian scientist discusses his country's environmental monitoring programs (by parameter and medium), points out their strengths and weaknesses, and indicates some possible directions for future efforts in the field of environmental monitoring at both the national and international level. (BT)

The global atmospheric monitoring plans of the World Meteorological Organization are detailed. Single and multipurpose basic monitoring systems and the monitoring of chemical properties are discussed. The relationship of the World Meteorological Organization with the United Nations environment program is discussed. A map of the World…

Using 1000 MW coal-fired central power stations as an example, the impacts upon other media (land, air, water) are analyzed when controls are imposed on one medium. The development of a methodology for assessing the cross-media impact of specific control technologies or strategies is illustrated. (Author/BT)

A conference convened by the American Medical Association in December 1974 heard the latest research findings on the effect of airborne substances on the body's defense mechanisms, hypersensitive reactions to various air pollutants, heart and respiratory diseases and illnesses in children. Air pollution is still a health problem. (BT)

To meet energy needs, the World's energy base must be broadly diversified. This diversification, including such possibilities as fossil fuels, nuclear, solar, geothermal, tidal and aeolian energy, must proceed without undue environmental damage and be economically feasible. Compromises between energy, economics and the environment will have to be…

Energy needs for environmental cleanup are assessed. Among the conclusions are: the quantities of energy required to achieve various environmental quality goals are small; energy needs for environmental protection can be offset by conservation measures and the conclusions in regard to primary energy closely correspond to those for electrical…

The technique of intermittent control systems for air quality control as developed and used by the Tennessee Valley Authority is investigated. Although controversial, all Tennessee Valley Authority sulfur dioxide elimination programs are scheduled to be operational this year. Existing or anticipated intermittent control systems are identified. (BT)

Integrated Exposure Assessment Monitoring is the coordination of environmental (air, water, land, and crops) monitoring networks to collect systematically pollutant exposure data for a specific receptor, usually man. (Author/BB)

A ten year study, being conducted by the Harvard School of Public Health in six cities since 1974, is a survey of children and adults for the health effects of pollutant levels. The environment is being monitored for: (1) sulfur dioxide, (2) sulfates, and (3) respirable particulates. (BT)
