Ammonia, methane, hydrogen sulphide and methyl mercaptides were analyzed in the atmospheres of 16 Finnish municipal waste water treatment plants and in 18 pumping stations. The sulphides were analyzed on site as it was found that, with the standard 0.5-l laminated plastic bags, significant amounts of the vapours were lost from the gas phase. The relative humidity of the sampled air was the most likely cause. Under normal operating conditions, sulphides varied from less than 0.07 to 53 micrograms l-1, with highest concentrations found at the sludge presses. Pumping stations had sulphide vapours from 0.07 to 0.5 microgram l-1. The presence of ammonia (0.007-3.5 micrograms l-1) and methane (0.7-18 micrograms l-1) confirmed the hypothesis of the anaerobic origin of the offensive gases. Although more effective ventilation without scrubbing the emission gases would reduce the health hazard in the plants it would burden the environment.
对16家芬兰城市污水处理厂和18个泵站的大气中的氨、甲烷、硫化氢和甲硫醇进行了分析。由于发现使用标准的0.5升层压塑料袋时，大量蒸汽会从气相中损失，因此对硫化物进行了现场分析。采样空气的相对湿度最有可能是造成这种情况的原因。在正常运行条件下，硫化物的含量从低于0.07微克/升至53微克/升不等，在污泥压滤机处发现的浓度最高。泵站的硫化物蒸汽含量为0.07微克/升至0.5微克/升。氨（0.007 - 3.5微克/升）和甲烷（0.7 - 18微克/升）的存在证实了恶臭气体厌氧来源的假设。尽管在不洗涤排放气体的情况下进行更有效的通风会降低工厂内的健康危害，但这会给环境带来负担。
