与土地使用的污水污泥有关的主要包括皮肤、粘膜和呼吸道的刺激,并伴有机会性感染。挥发性排放物和有机粉尘似乎是刺激的主要来源。偶尔,有私人水井的受影响居民报告慢性胃肠问题。为了防止急性健康影响,我们建议将目前基于指示病原体水平(A类和B类)对污泥进行分类的系统替换为单一的高水平消毒标准,并改进用于处理污泥的方法,以减少刺激性化学物质,特别是内毒素的水平。一项对受土地应用做法的安全影响或关心这种做法的个人的全国意见调查表明,大多数人并不认为这种做法本身不安全,但他们对联邦和州机构支持的研究缺乏信心
associated with land-applied sewage sludges primarily involve irritation of the skin, mucous membranes, and the respiratory tract accompanied by opportunistic infections. Volatile emissions and organic dusts appear to be the main source of irritation. Occasionally, chronic gastrointestinal problems are reported by affected residents who have private wells. To prevent acute health effects, we recommend that the current system of classifying sludges based on indicator pathogen levels (Class A and Class B) be replaced with a single high-level disinfection standard and that methods used to treat sludges be improved to reduce levels of irritant chemicals, especially endotoxins. A national opinion survey of individuals impacted by or concerned about the safety of land-application practices indicated that most did not consider the practice inherently unsafe but that they lacked confidence in research supported by federal and state agencies
