   "Particulate matter has become one of today's most important environmental issues and it encompasses many industries," said Kris Chawla of Alberta Agriculture.
   
   "It's recognized that feedlots and other agricultural operations contribute to the amount of airborne PM, but in order to evaluate the potential risk of those emissions and develop reduction strategies, a need exists for a sound, scientific understanding of their precise contribution."
   
   He said Canada's environment ministers are developing standards for particulate matter and ozone. Many Alberta stakeholder groups are involved in the development of strategies to meet their needs in managing the ambient PM level.
   
   The feedlot study aims to determine the characteristics of PM emitted from various areas of feedlots, including feed bunks, holding pens and gravel roads, due to animal or vehicle movement, and how that PM is dispersed in surrounding areas.
   
   "Information and recommendations generated from our project will help others evaluate the exposure risk to humans and animals associated with feedlot activities," Chawla said."This will help the industry to implement good management practices for emissions associated with specific types of operations, and evaluate the effect on the surrounding area."
   
   Researchers have collected fine and coarse dust emission samples from two feedlots in southern Alberta to study chemical and biological characteristics.
   
   Chawla said analysis is expected to be completed by March. Researchers will then develop recommendations for feedlot operators.
   
   "For example, if we find that 60 percent of the PM on a feedlot is from a gravel road, we can suggest producers keep their gravel roads moist to reduce the amount of dust that gets airborne. Also, by determining the specific composition of dust emissions, we'll be able to tell producers which compounds should be their biggest concern."
   
   A key part of the study will be to determine the transport and dispersion of the PM in ambient air, Chawla said.

   "Particulate matter has become one of today's most important environmental issues and it encompasses many industries," says Kris Chawla, an AAFRD engineer. "It's recognized that feedlots and other agricultural operations contribute to the amount of airborne PM, but in order to evaluate the potential risk of those emissions and develop reduction strategies, a need exists for a sound, scientific understanding of their precise contribution."
   
   Under the Canada-wide Accord on Environmental Harmonization, the Canadian Council of Ministers of Environment is developing standards for particulate matter and ozone, he says. Many Alberta stakeholder groups are involved in the development of strategies to meet their needs in managing the ambient PM level in Alberta.
   
   The current feedlot study aims to determine the characteristics of PM emitted from various areas of feedlots, including feedbunks, holding pens and gravel roads, due to both animal or vehicle movement, and how that PM is dispersed in surrounding areas.
   
   "Information and recommendations generated from our project will help others evaluate the exposure risk to humans and animals, associated with feedlot activities," says Chawla. "This will help the industry to implement good management practices for emissions associated with specific types of operations, and evaluate the effect on the surrounding area."
   
   So far, researchers have collected both fine and coarse dust emission samples from two feedlots in southern Alberta. They are now analyzing the composition of those samples for their chemical and biological characteristics.
   
   Analysis is expected to be completed by March 2003, says Chawla. Researchers will then develop recommendations for feedlot operators. "For example, if we find that 60 percent of the PM on a feedlot is from a gravel road, we can suggest producers keep their gravel roads moist to reduce the amount of dust that gets airborne. Also, by determining the specific composition of dust emissions, we'll be able to tell producers which compounds should be their biggest concern."
   
   A key part of the study will be to determine the transport and dispersion of the PM in ambient air, says Chawla "It's this information that will demonstrate for us how these particulates circulate throughout the feedlot and in areas surrounding the feedlot."
