Size fractionated particulate matter emissions from a broiler house in Southern Ontario, Canada.

In 1999, the National Emission Inventory and Project Task Group developed particulate matter emission inventories for the Canadian poultry industry using Canadian poultry census data and emission factors for all types of poultry operations based on U.S. Environmental Protection Agency and British Columbia/Greater Vancouver Regional District data [MOE.

Global gridded emission inventories of beta-hexachlorocyclohexane.

As the contamination of beta-hexachlorocyclohexane (beta-HCH) in the Arctic air, seawater, and biota is an environmental concern, there is a need for emission inventories of beta-HCH to be used by the modeling community to predict the fate and transport of beta-HCH. This paper presents such emission inventories for beta-HCH. The total global usage of beta-HCH between 1945 and 2000 is estimated at 850 kt, 230 kt of which was emitted to the atmosphere over the same time period.
