Particulate Matter Emissions from a High-rise Layer House in Iowa

Abstract

Particulate matter (PM) in animal feeding operations is a concern for the occupants and the surrounding community. Baseline measurements of the concentration and emission rate of PM are the first step toward assessing the environmental impact of animal feeding operation and evaluating the effectiveness of dust control strategies. This study presents the results of the PM measurement at a high-rise layer house in central Iowa. The average PM10 emission rate over the 9-month measurement period was 21.6 (±10 S.D.) mg/bird/ day. Comparing with the emission rates reported literature, the mean and range of PM10 emission from highrise layer hen barns using cage systems were 33.5 and 19-48 mg/bird/day. The average PM2.5 emission rate over the measurement period was 2 (± 1.5 S.D.) mg/bird/day, which is less than literature values of 3.52-14.2 mg/bird/day.

Concentration, Size Distribution and Electrostatic Charge of Laying Hen House Particulate Matter

“…The characteristics of PM (e.g., concentration, number, and mass) inside livestock housing vary according to the type of animal, building, and environmental conditions. Previous studies (Li et al, 2011;Green et al, 2007;Lim et al, 2007;Heber et al, 2005;Vucemilo et al, 2007;Shuhai et al, 2009) showed that the mean PM concentration measured inside layer housed (cage system) were 1.96, 0.33, 0.032 mg/m 3 for TSP, PM 10 , and PM 2.5 , respectively. The ranges of these concentrations were 0.75-4, 0.03-0.56, and 0.03-0.04 mg/m 3 for TSP, PM 10 , and PM 2.5 , respectively.…”
