Abstract 1,3-Butadiene is a substance that is a gas at normal ambient temperatures. Trace amounts, mostly derived from the combustion of petroleum and other fuels, can be found in the atmosphere. In industry, it is used in the production of synthetic rubber and is also present in some liquid petroleum gases. There is some epidemiological evidence that workers exposed to 1,3-butadiene have a slightly higher than expected risk of developing certain cancers (lymphoid system, bone marrow, lymphomas, leukaemias). Its genotoxic and carcinogenic effects have also been shown in animal experiments. After reviewing measurement methods and the evidence for health risks, this document recommends an Air Quality Standard of 1ppb as a running annual average for 1,3-butadiene, a level not normally exceeded in urban air in the United Kingdom.
