treated wood 

TOXICOLOGY

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. 

The US lumber industry stopped in 2003 treating residential lumber with arsenic and chromium–chromated copper arsenate, or CCA, replacing CCA with copper based pesticides. 

Synonym Pressure-treated wood
