Task 2.5 - Effectiveness of Sorbents for Trace Elements: Semi-annual report, January 1-June 30, 1995
Significant quantities of trace elements are emitted to the atmosphere each year as a result of the large volumes of coal used in combustion and gasification processes as well as from other industrial and commercial operations, such as waste incineration and chlorine and alkali production (1). Owing to their potentially harmful effects on the ecosystem, eleven trace elements have been identified for control action under the 1990 Clean Air Act Amendments: beryllium, chromium, manganese, cobalt, nickel, arsenic, selenium, cadmium, antimony, lead, and mercury. Although appearing as trace species, arsenic, selenium, and mercury are of particular concern, since they can occur in gaseous or submicron fume form; consequently, substantial amounts can pass through the conventional collection devices such as precipitators and baghouses.
