这项研究的目的是在全球范围内评估瓶装饮用水中无机和有机物质以及微生物污染物的含量。研究结果与世卫组织指南进行了比较,EPA标准,欧洲联盟(欧盟)指令,和国际瓶装水协会(IBWA)起草的标准。我们的评论显示,46%的研究集中在有机污染物上,25%的物理化学参数,12%的微量元素,7%对微生物质量、10%的微塑料(MPs)和放射性核素元素。总的来说,从54项针对有机污染物(OCs)化合物的研究中,11%的研究显示OCs浓度高于标准允许限值。根据本综述获得的结果,几个OC,无机污染物(IOC),包括CHCl3、CHBrCl2、DEHP、苯,苯乙烯,Ba,As,Hg,pb,Ag,F,一些国家的瓶装饮用水中的NO3和SO4高于国际准则值,这可能在很长一段时间内对人类健康造成风险。此外,一些具有已知或未知健康影响的有问题的污染物,如EDC,DBP,AA,议员们,某些放射性核素(40K和222Rn)缺乏国际准则规定的瓶装饮用水的最大允许值。OCs和IOCs的风险指数(HI)(CHBrCl2,Ba,As,和Hg)在成人和儿童中高于1,儿童CHCl3的HI值大于1。因此,需要进一步研究才能更好地了解瓶装饮用水中的所有污染物水平。
The aim of this study was to evaluate the levels of inorganic and organic substances as well as microbial contaminants in bottled drinking water on a global scale. The findings were compared to WHO guidelines, EPA standards, European Union (EU) directive, and standards drafted by International Bottled Water Association (IBWA). Our
review showed that 46% of studies focused on the organic contaminants, 25% on physicochemical parameters, 12% on trace elements, 7% on the microbial quality, and 10% on microplastics (MPs) and radionuclides elements. Overall, from the 54 studies focusing on organic contaminants (OCs) compounds, 11% of studies had higher OCs concentrations than the standard permissible limit. According to the obtained results from this
review, several OCs, inorganic contaminants (IOCs), including CHCl3, CHBrCl2, DEHP, benzene, styrene, Ba, As, Hg, pb, Ag, F, NO3, and SO4 in bottled drinking water of some countries were higher than the international guidelines values that may cause risks for human health in a long period of time. Furthermore, some problematic contaminants with known or unknown health effects such as EDCs, DBP, AA, MPs, and some radionuclides (40K and 222Rn) lack maximum permissible values in bottled drinking water as stipulated by international guidelines. The risk index (HI) for OCs and IOCs (CHBrCl2, Ba, As, and Hg) was higher than 1 in adults and children, and the value of HI for CHCl3 in children was more than 1. Thus, further studies are required to have a better understanding of all contaminants levels in bottled drinking water.
