Potential human health effects of acid rain: report of a workshop.

This report summarizes the potential impact of the acid precipitation phenomenon on human health. There are two major components to this phenomenon: the predepositional phase, during which there is direct human exposure to acidic substances from ambient air, and the post-depositional phase, in which the deposition of acid materials on water and soil results in the mobilization, transport, and even chemical transformation of toxic metals. Acidification increases bioconversion of mercury to methylmercury, which accumulates in fish, increasing the risk to toxicity in people who eat fish. Increase in water and soil content of lead and cadmium increases human exposure to these metals which become additive to other sources presently under regulatory control. The potential adverse health effects of increased human exposure to aluminum is not known at the present time.

The effects of motivational interventions upon the exercise adherence of high and low self-motivated adults.

Two studies were carried out to investigate the utility of an interactionist approach to motivating involvement in an exercise program. In both studies the Self-Motivation Scale (Dishman, Ickes and Morgan, 1980) was used to classify program participants according to their level of self-motivation. Participants for each category were then assigned to experimental or control conditions. A decision balance-sheet technique was the treatment intervention in the first study while a structured social support intervention was implemented in the second study. In both cases, the motivational treatment resulted in an improvement in program attendance but there was no effect due to level of self-motivation nor its interaction with the treatment. The results are interpreted as being consistent with a situationist perspective of behavior; however, the need for further research using an interactionist approach is emphasized. Implications for exercise practice are discussed.
