Hazardous substances, natural laws

The chemical manufacturing process has an EC connection. Commencing with the extraction of raw materials from the earth to the delivery and use of the final products it is inevitable that hazardous substances will be formed. This is the first law (refer to Table 1 for the five natural laws of hazardous waste).The use of green engineering and product substitution will substantially reduce the mass of hazardous materials produced but will not eliminate the problem entirely. The second law concerns recycle and reuse, but it... 

The combined efforts of the manufacturing engineers, the waste treatment engineers, and pollution control applied scientists not withstanding, residual leaks are inevitable (natural law no. 4 in Table 1). It is clear that quantities of hazardous substances will always enter the natural environment. The earth forces that result in volcanic chemical emissions and the hazardous substances formed by many plants and animals for example have been ever present. However, it is the impact of human activities that has been the most... 

For a number of installations where hazardous substances must be present due to the nature of the operation, or which may originate during an incident, safety analyses are required by law [7-45]. The purpose of analysis is to institute preventive measures in order to forestall accidents or to limit their consequences as much as possible. If suitable measures are taken at an early point in time, incident-related releases of toxic or flammable substances usually result in short-term environmental stresses only.

The decade of the 1970 s has seen mushrooming growth in concern for environmental health and the broader issues of the natural environment. This attitude is reflected in much legislation. Following incidents involving chemical pollutants, and recognition of chemical hazards and potential impacts of toxic substances, the Toxic Substances Control Act (TSCA) was added to prior law. Objectives of TSCA and its impacts on the chemical industry are addressed elsewhere within this symposium. The present paper addresses education to meet the mandates of TSCA.
