Disinfection of swimming pools with chlorine and derivatives: formation of organochlorinated and organobrominated compounds and exposure of pool personnel and swimmers

引用

Natural Science 2010年第2期2卷 68-78页

作者： Maria-Cristina Aprea Bruno banchi Liana Lunghini Massimo Pagliantini Antonio Peruzzi Gianfranco Sciarra 不详

Chlorination of pool water leads to the forma-tion of many by-products, chloroform usually being the most abundant. The paper reports the results of a study evaluating exposure of bath-ers and pool employees to trihalomethanes (chloroform, bromodichloromethane, dibromo-chloromethane, bromoform) in four indoor swimming pools with chlorinated water. Chlo-roform concentrations in environmental air samples when the pool was in use (about 9 h), in the range 1-182 μg/m3, were greater near the pool than in the change rooms, passageways and offices. Chloroform concentrations in per-sonal air samples of pool employees were in the range 18-138 μg/m3. Urinary concentrations of chloroform averaged (geometric means) 0.123 and 0.165 μg/l and 0.404 and 0.342 μg/l prior and at the end of exposure during in water and out of water activities, respectively. The significant increase in urinary excretion of chloroform confirms that the source of the contaminant was pool water. Absorption of chloroform, estimated from airborne and water concentrations, was significantly correlated with delta chloroform (after/before exposure) and urinary concentra-tions of chloroform at the end of exposure. As chloroform is a toxic and possibly carcinogenic substance, these observations pose a problem principally for the general population of pool users.

辐射带粒子是近地空间卫星总剂量辐射的主要来源。文章分析了内辐射带不同高度轨道的辐射环境特性;并利用Geant4程序,针对内辐射带质子环境进行不同材料的屏蔽效能计算。结果表明:虽然传统的低‒高‒低原子序数材料三明治屏蔽结构对电子具有较高的屏蔽效能,却并不适用于以质子环境为主的轨道;对于工作在3000 km圆轨道、5年寿命的卫星,若要将总剂量降至30 krad(Si)以下,使用PE屏蔽材料可比Al屏蔽减重28%。
