表征城市污水污泥中与环境健康相关的有机污染物（OCs）的发生对于这些丰富材料的安全处理和处置至关重要。本荟萃分析旨在（i）总结对中国和美国污水污泥化学成分进行的研究程度，世界上两个最大的化学品生产商，（ii）确定优先关注的化学品组，（iii）定量比较国家之间的污泥中的化学丰度，（iv）确定污泥中污染物累积的纵向趋势，以及（v）确定污泥中有机碳浓度的数据差距。对美国生活和工业废水处理过程中产生的污泥中有机碳的浓度进行了文献检索，并与最近建立的数据库中提取的中国污泥中的污染物水平进行了统计学比较。OC发生的纵向趋势进行了解释，在国家化学品生产，使用统计和法规的背景下。美国共发现105项关于污泥中有机氯化合物的研究，而中国共发现159项。在监测的1，175种OC中，23%的分析物在两个国家（n = 269）进行了监测，41%（n = 480）仅在中国进行了监测，其余36%（n = 426）仅在美国进行了监测。平均而言，美国的有机氯化合物浓度比中国的污水污泥高4.0倍，其中烷基酚聚氧乙烯醚的检出率最高。来自一个新的两国数据库的数据表明，并重申需要在这两个国家进行额外的化学监测，对即将在陆地上应用的污泥中所含的新出现的有机氯化合物进行风险评估，并加强对中国污泥处置限制的执行，目前多达40%的污泥被不适当地倾倒。
Characterizing the occurrence of organic contaminants (OCs) of environmental health concern in municipal sewage sludges is essential for safe handling and disposal of these abundant materials. This meta-analysis aimed to (i) summarize the extent of studies performed on the chemical composition of sewage sludges from China and the U.S., the world’s two largest chemical producers, (ii) identify chemical groups of priority concern, (iii) quantitatively compare chemical abundance in sludge between nations, (iv) determine longitudinal contaminant accumulation trends in sludge, and (v) identify data gaps with regard to OC concentrations in sludge. A literature search was conducted on concentrations of OCs in U.S. sludges produced during treatment of domestic and industrial wastewater and compared statistically to contaminant levels in Chinese sludge abstracted from a recently established database. Longitudinal trends of OC occurrence were interpreted in the context of national chemical production, usage statistics, and regulations. A total of 105 studies on OCs in U.S. sewage sludge were found, while a total of 159 had been found in China. Among 1,175 OCs monitored for, 23% of all analytes had been monitored in both countries (n = 269), 41% (n = 480) in China only, and the remaining 36% (n = 426) in the U.S. only. On average, concentrations of OCs were 4.0 times higher in U.S. than in Chinese sewage sludge, with the highest detection being observed for alkylphenol ethoxylates. Data from a new binational database on toxic OCs in sewage sludges suggest and reiterates the need for additional chemical monitoring in both countries, risk assessments for emerging OCs contained in sludges destined for application on land, and stronger enforcement of sludge disposal restrictions in China, where as much as 40% of sludge is currently being dumped improperly.
