Particulate matter concentrations and emissions of a fattening pig facility in northern China

Özet

Particulate matter (PM) from pig farms are pollutants affecting human health and the environmental. The information on this topic is limited in China to date. A one-year study to monitor the dynamics of total suspendedparticles (TSP), particulate matter with diameter less than 10 μm (PM10) and 2.5 μm (PM2.5) was conducted inthree pig fattening facilities of a commercial pig farm in Beijing, China. The results showed that daily meanindoor TSP, PM10 and PM2.5 concentrations were 0.34–4.96, 0.15 to 1.01, and 0.06–0.20 mg·m−³. The averageemission rate (ER) of PM per animal (pig) and livestock unit (LU = 500 kg) was 1.06 ± 0.65 g d−1pig−1(11.83 ± 7.07 g d−1LU−1) for TSP, 0.50 ± 0.39 g d−1pig−1(5.53 ± 4.10 g d−1LU−1) for PM10, and0.12 ± 0.17 g d−1pig−1(1.42 ± 1.86 g d−1LU−1) for PM2.5, respectively. The daily maximum concentrations of TSP and PM10 exceeded the Chinese environmental quality standard for the livestock and poultryfarm (NY/T388-1999). The concentration of PM2.5 in animal house and emissions of PM form animal productionhave not been regulated in China, it is necessary to focus on mitigation measures to minimize the impacts of PM.
