Includes bibliographical references. “The physical magnitude of the Canadian air, land and water environments together with their natural scavenging mechanisms can assimilate more pollution than is produced in energy conversion. Nonetheless, concentrations of pollution at single sources and the proliferation of sources exceeds the capacity of the environment in some specific, but widely separated, areas. Thus, if our environments are to be given a reasonable opportunity to assimilate pollution, there is no choice but to ensure that stack emissions are minimized and, having done that, to make full use of the dispersion capacity of air sheds. However, neither fuel highgrading, i.e. the use of premium fuels as an expedient for the moment, nor pollution controls that waste energy are viable long-term solutions for protecting the environment"--Abstract, p. 1. gccst Atmospheric emissions gccst Pollution prevention gccst Environmental protection Canada.
