Arsenic & compounds: Sources of emissions
Industry sources
Mining and metal manufacturing are the largest sources of arsenic in Australia. Electricity supply, water supply, sewerage and draining surfaces, can also emit arsenic. Manufacturing industries where arsenic may be used include: food, paper and paper products, glass and glass products, petroleum and coal products and chemicals.
Diffuse sources, and industry sources included in diffuse emissions data
Paved and unpaved roads, windblown dust, burning fuels or wildfires, motor vehicles, solid, liquid and gas fuel combustion, lawn mowing, boating (recreational and commercial), railways, barbeques and backyard incineration activities are all capable of causing arsenic emissionss.
Natural sources
Arsenic and compounds occurs naturally in the earth's crust in ores and minerals. These are generally at low concentrations. Arsenic is released into the air by volcanoes and the weathering of arsenic-containing ores.
Transport sources
Arsenic emissions may be present from the vehicle exhaust of cars, aeroplanes, railway operations and from commercial shipping or boating.
