Abstract

A field survey of Total Reduced Sulfur (TRS) concentrations in the vicinity of beef cattle feedlots was conducted to compare field observations against current regulatory thresholds. It was observed that TRS levels in the vicinity of beef cattle feedlots are not likely to exceed current regulatory thresholds used by Nebraska. It was further noted concentration of TRS varies with air temperature and time of day. However, wet feedlot surface conditions had almost no impact upon observed TRS concentrations. Feedlots typically do not contribute significant hydrogen sulfide emissions and are unlikely to produce concentrations in excess of current Nebraska Department of Environmental Quality regulatory limits.
