Wood–in particular, that used for construction–which is impregnated with preservatives–e.g., chromium-copper-arsenate, creosote, inorganic arsenicals, pentachlorophenol, to increase its useful life, thwart insects, fungi, etc. Chronic exposure to the fumes of burning wood or skin contact with treated wood may produce heavy metal intoxication.
