Manganese--a public health concern: its relevance for occupational health and safety policy and regulation in South Africa.

摘要

Concerns about the effects of low-level manganese exposures on human health arise at a time when South Africa finds itself in competition with newcomers to the market economy, China and the CIS. This case study illustrates how decisions about occupational health and safety and the environment are influenced by incompleteness of scientific knowledge, competing interests, differences over what is fair or just, and the compartmentalization of public policy. In addition, an assessment is made of the ability of the occupational health and safety system in South Africa in its current form to address the challenges posed by manganese-related issues. The importance of tracking developments abroad, strengthening participatory processes, developing national policy, linking economic policy and OHS policy, and establishing appropriate trade agreements is stressed.
