The aim of the study was to assess the levels of inhalable dust, endotoxins and (1–3)-β-d-glucans as agents harmful to the respiratory tract of workers of municipal waste sorting plants and interaction between these agents based on the measurements taken in two plants with different processing capacities. The study was conducted in summer season in two waste sorting plants (WSPs) differing in processing capacity. Samples of bioaerosol for inhalable dust (gravimetric method), endotoxins (LAL test in kinetic, chromogenic version) and (1–3)-β-d-glucans (Glucatell test in kinetic version) were collected from 42 sorting workers using individual aspirators with glass fiber filters during the work shift. Average geometric concentrations (geometric standard deviation; min–max) of inhalable dust, endotoxins and (1–3)-β-d-glucans were: WSP1: 1.7 mg m−3 (2.2; 0.6–6.9 mg m−3); 15.9 ng m−3 (2.1; 5.4–78.9 ng m−3), 55.1 ng m−3 (1.8; 20.7–188.6 ng m−3) and WSP2: 0.8 mg m−3 (2.2; 0.2–3.8 mg m−3), 9.8 ng m−3 (2.4; 1.6–29.7 ng m−3), 45.0 ng m−3 (3.2, 5.7–212.9 ng m−3), respectively. A significantly higher concentration of inhalable dust was recorded in WSP1 with bigger processing capacity compared to WSP2 (less processing capacity). Significant (p < 0.05) and very high correlations (Spearman rank R > 0.7) were found between the concentrations of all analyzed harmful agents. Processing capacity of waste sorting plants differentially affects the concentrations of inhalable dust, whereas concentrations of endotoxins and glucans are less clearly affected. This suggests that relative concentrations of endotoxin and glucan are depending on the waste sorting capacity.

可吸入粉尘、内毒素和 (1-3)-β-d-葡聚糖作为废物分拣厂环境暴露指标

该研究的目的是评估可吸入灰尘、内毒素和 (1-3)-β-d-葡聚糖作为对城市垃圾分拣厂工人呼吸道有害的物质的水平,以及这些物质之间的相互作用。取自两个不同处理能力的工厂。该研究是在夏季在两个处理能力不同的垃圾分类厂 (WSP) 中进行的。可吸入粉尘的生物气溶胶样品(重量法)、内毒素(动力学、显色版 LAL 测试)和 (1-3)-β-d-葡聚糖(动力学版 Glucatell 测试)使用单独的抽吸器从 42 名分拣工人那里收集轮班期间的玻璃纤维过滤器。可吸入粉尘、内毒素和 (1-3)-β-d-葡聚糖的平均几何浓度(几何标准偏差;最小值-最大值)为: WSP1:1.7 mg m-3 (2.2; 0.6–6.9 毫克 m−3);15.9 ng m-3 (2.1; 5.4-78.9 ng m-3), 55.1 ng m-3 (1.8; 20.7-188.6 ng m-3) 和 WSP2: 0.8 mg m-3 (2.2; 0.2-3.8 mg m- 3), 9.8 ng m-3 (2.4; 1.6–29.7 ng m-3), 45.0 ng m-3 (3.2, 5.7–212.9 ng m-3)。与 WSP2(较低的处理能力)相比,处理能力更大的 WSP1 中记录的可吸入粉尘浓度明显更高。在所有分析的有害物质的浓度之间发现了显着(p < 0.05)和非常高的相关性(Spearman 等级 R > 0.7)。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。9 ng m-3), 55.1 ng m-3 (1.8; 20.7–188.6 ng m-3) 和 WSP2: 0.8 mg m-3 (2.2; 0.2-3.8 mg m-3), 9.8 ng m-3 (2.4) ; 1.6–29.7 ng m-3), 45.0 ng m-3 (3.2, 5.7–212.9 ng m-3)。与 WSP2(较低的处理能力)相比,处理能力更大的 WSP1 中记录的可吸入粉尘浓度明显更高。在所有分析的有害物质的浓度之间发现了显着(p < 0.05)和非常高的相关性(Spearman 等级 R > 0.7)。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。9 ng m-3), 55.1 ng m-3 (1.8; 20.7–188.6 ng m-3) 和 WSP2: 0.8 mg m-3 (2.2; 0.2-3.8 mg m-3), 9.8 ng m-3 (2.4) ; 1.6–29.7 ng m-3), 45.0 ng m-3 (3.2, 5.7–212.9 ng m-3)。与 WSP2(较低的处理能力)相比,处理能力更大的 WSP1 中记录的可吸入粉尘浓度明显更高。在所有分析的有害物质的浓度之间发现了显着(p < 0.05)和非常高的相关性(Spearman 等级 R > 0.7)。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。8 mg m-3), 9.8 ng m-3 (2.4; 1.6–29.7 ng m-3), 45.0 ng m-3 (3.2, 5.7–212.9 ng m-3)。与 WSP2(较低的处理能力)相比,处理能力更大的 WSP1 中记录的可吸入粉尘浓度明显更高。在所有分析的有害物质的浓度之间发现了显着(p < 0.05)和非常高的相关性(Spearman 等级 R > 0.7)。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。8 mg m-3), 9.8 ng m-3 (2.4; 1.6–29.7 ng m-3), 45.0 ng m-3 (3.2, 5.7–212.9 ng m-3)。与 WSP2(较低的处理能力)相比,处理能力更大的 WSP1 中记录的可吸入粉尘浓度明显更高。在所有分析的有害物质的浓度之间发现了显着(p < 0.05)和非常高的相关性(Spearman 等级 R > 0.7)。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。与 WSP2(较低的处理能力)相比,处理能力更大的 WSP1 中记录的可吸入粉尘浓度明显更高。在所有分析的有害物质的浓度之间发现了显着(p < 0.05)和非常高的相关性(Spearman 等级 R > 0.7)。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。与 WSP2(较低的处理能力)相比,处理能力更大的 WSP1 中记录的可吸入粉尘浓度明显更高。在所有分析的有害物质的浓度之间发现了显着(p < 0.05)和非常高的相关性(Spearman 等级 R > 0.7)。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。垃圾分拣厂的处理能力对可吸入粉尘的浓度有不同的影响,而内毒素和葡聚糖的浓度则不太明显。这表明内毒素和葡聚糖的相对浓度取决于废物分类能力。
