a complex I t y p e of air pollution due to its " combination of hundreds of odorous compounds with very low concentrations Odor pollution is particularly concerned because of its impact on human health and the ability to spread over a wide area Determination of pollution sources and odor pollutant composition is very importants in order to find out appropriate odor treatment technology Based on monitoring results of typical industries such as tannery, rubber latex, animal feed and livestock, this report presents analytical results of odor compounds as well as assesses the advantages and
