Abstract Abstract: There is increasing concern about the great diversity of chemicals and other contaminants released into the environment. In the past ten years, the issue of inhalable particulate matter has exploded as a public health issue. Currently, there is focus on interaction between atmospheric contaminants and the human immune system. When released to the atmosphere, contaminants enter a pathway by which large areas and populations may be exposed to these substances. It is critical that regulatory agencies, such as BC Environment, inventory these contaminants, both in response to acute incidents and for chronic exposure. Skeena Region has traditionally emphasised monitoring and assessment of PAHs. Recent studies have been expanded to include metals. The current status of these programmes is reviewed and monitoring results of the Kitimat metals programme, in the middle of its minimum duration, are presented. Data capture has been good for the programme to date. Concentrations less than minimum detection limits are typical for beryllium, cadmium, lead, nickel in the residential areas, selenium, and approximately one-quarter of the silicon samples.
