The evolution of gases during the handling of animal slurry was investigated at five sites. Particular attention was paid to the mixing and emptying operations since it is when performing these that personnel are most likely to be at risk of exposure. The main hazard was found to be high transient concentrations of hydrogen sulphide presenting in some cases a serious acute toxicity problem. Time-weighted average exposures did not generally indicate any long-term exposure risk. Other features noted were the evolution of ammonia and methane, although not at high levels, and some increase in the carbon dioxide concentration. Some reduction in oxygen concentration was measured, but generally the risk of poisoning by hydrogen sulphide was more serious than the risk of asphyxiation.
在五个地点对处理动物粪便过程中气体的逸出情况进行了调查。特别关注了搅拌和排空操作，因为在进行这些操作时人员最有可能面临接触风险。结果发现主要危害是硫化氢的高瞬时浓度，在某些情况下会带来严重的急性毒性问题。时间加权平均暴露量一般未显示出任何长期暴露风险。还注意到的其他特征是氨和甲烷的逸出，尽管含量不高，以及二氧化碳浓度有所增加。测量到氧气浓度有所降低，但一般来说，硫化氢中毒的风险比窒息风险更严重。
