氨基酸厂废水对土壤—植物系统影响的研究

莴苣盆栽试验表明,氨基酸厂废水在适宜浓度下,可以提高蔬菜的鲜嫩度和维生素C、可溶性糖的含量,并使全氯和硝酸盐的含量限定在卫生标准之内;同时又不会使土壤原有性质产生破坏。废水在紫色土上的最适浓度为1:80(废水与清水体积比,下同),但它在作物生长前期表现为毒害作用与低浓度促进作用并存,且以毒害作用为主,直到后期才表现出营养肥效作用。

Disinfection byproducts in indoor swimming pool water: Detection and human lifetime health risk assessment

Quantification of regulated and emerging disinfection byproducts (DBPs) in swimming pool water, as well as the assessment of their lifetime health risk are limited in China. In this study, the occurrence of regulated DBPs (e.g., trihalomethanes, haloacetic acids) and emerging DBPs (e.g., haloacetonitriles, haloacetaldehydes) in indoor swimming pool water and the corresponding source water at a city in Eastern China were determined. The concentrations of DBPs in swimming pool water were 1-2 orders of magnitude higher than that in source water. Lifetime cancer and non-cancer risks of DBPs stemming from swimming pool water were also estimated. Inhalation and dermal exposure were the most significant exposure routes related to swimming pool DBP cancer and non-cancer risks. For the first time, buccal and aural exposure were considered, and were proven to be important routes of DBP exposure (accounting for 17.9%-38.9% of total risk). The cancer risks of DBPs for all swimmers were higher than 10⁻⁶ of lifetime exposure risk recommended by United States Environmental Protection Agency, and the competitive adult swimmers experienced the highest cancer risk (7.82 × 10⁻⁵). These findings provide important information and perspectives for future efforts to lower the health risks associated with exposure to DBPs in swimming pool water.
