新疆阿克苏地区初冬时节肉牛舍环境空气质量的测定与评价

[目的]为了解新疆阿克苏地区初冬时节肉牛舍的环境空气质量情况，对肉牛舍的环境空气质量进行了评价。[方法]对阿克苏地区具有代表性的肉牛养殖场的1栋牛舍中的CO2、NH3、CH4和H2S4种主要有害气体以及空气中的PMl0、TSP进行现场测定，并对牛舍的环境空气质量进行分析评价。[结果]测定结果显示，肉牛舍的环境空气质量指标中CO：平均浓度为404mg/m3；NH3平均浓度为4.0mg/m3；CH4和H2S平均浓度〈0mg/m3；PMl0平均浓度为0.04mg／m3；TSP平均浓度为1.222mg/m3；C02、NH3、CH4、H2S、PMl0、TSP最高浓度和日平均浓度均低于：畜禽舍的环境空气质量标准。[结论]该肉牛舍的空气质量属于清洁级别，符合肉牛养殖环境标准。

Determination and Evaluation on the Ambient Air Quality of Beef Cattle Cowshed in Early Winter of Aksu,Xinjiang

[ Objective ] In order to understand the ambient air quality of beef cattle cowshed in early winter of Aksu, Xinjiang, an evaluate ambient air quality in beef cattle cowshed. [Method] Four kinds of main harmful gas （CO2, NH3, CH4 and H2S） in cowshed of beef cattle farm and PM10 and TSP in ambient air in Aksu of Xinjiang were measured. Ambient air quality in cowshe was evaluated. [Result] Measurement result showed that CO2 concentration in beef cattle cowshed was 404 mg/m3,NH3 concentration was 4.0 mg/m3, CH4 and H2S were less than 0 mg/m3, PM10 was 0.04 mg/m3, and TSP was 1.222 mg/m3. The highest and daily average concentrations of CO2, NH3, CH4, H2S, PM10 and TSP were all lower than ambient air quality standard of the livestock and poultry. [Conclusionl The air quality of beef cattle cowshed belonged to clean level, in accord with environmental standards of the beef cattle breeding.
