"We are hoping to see more intensive and detailed surveys of disinfection byproducts and other contaminants performed at the national level."Īccording to the researchers, high-resolution spatial and temporal data will enable researchers to better reveal the relationship between tap water quality and human health, thus helping to lower tap water risks.Tap - tap1 S3 n ▬▬▬▬▬▬▬ 1¦(water/gas)¦ 2¦(a light hit)¦ 3 on tap 4¦(dancing)¦ 5¦(telephone)¦ 6¦(barrel)¦ 7¦(tune)¦ ▬▬▬▬▬▬▬ [Sense: 2, 4, 7 … Dictionary of contemporary English ![]() "This is the first attempt to evaluate the health risk of tap water," said Liu Mengjie, first author of the study. Besides disinfection byproducts, other potential microcontaminants in tap water can also be removed by nanofiltration," said Yu.Īll in all, rapid urbanization is raising concerns about the impact of various pollutants on drinking water and health. "Nanofiltration is a promising point-of-use technology to guarantee household drinking water safety. In addition to proposing altering water sources and enhancing water treatment processes, the researchers also demonstrated that nanofiltration is as an effective household treatment to improve water quality and reduce the health risk of disinfection byproducts. For example, water supplied to the Haihe River region through the South-to-North Water Diversion Project has not only alleviated the region's water scarcity, but has also improved water quality in an area that previously suffered from severe organic water pollution. Sourcing water from less polluted areas may also be a solution, according to the researchers. Therefore, this approach can be used to reduce the risk of disinfection byproducts in economically developed areas. In Shanghai, more than 60% of the city's water plants use such biofiltration to enhance their water treatment, resulting in a much lower disinfection byproduct level than China's three other largest cities. "Therefore, countries and regions experiencing rapid socioeconomic development might be facing higher disinfection byproduct toxicity, and they should consider adopting solutions to address the potential health risk caused by poor drinking water," said Yu Wenzheng, corresponding author of the study.Īdvanced water treatment such as ozone biofiltration can effectively remove disinfection byproduct precursors, according to the researchers. In addition, the concentration of bromine-containing disinfection byproducts is strongly associated with GDP, pollutant discharge, and other human factors. Coastal regions with seawater intrusion showed higher bromine-containing disinfection byproducts and associated toxicity. Bromine-containing disinfection byproducts are more toxic than those containing chlorine. ![]() However, the toxicity of disinfection byproducts is not only determined by their concentration, but also by their composition. That is, regions with a high incidence of adverse health outcomes are characterized by significantly higher concentrations of disinfection byproducts than other areas. They found notable geographical differences in disinfection byproduct concentrations in tap water across China, with higher concentrations in the northeast and the mid-Yangtze River region.īased on officially published disease data, the researchers then verified the spatial relationship between disinfection byproducts and adverse health outcomes. In this study, the researchers conducted a national assessment of tap water across China. Although disinfection is meant to make water safer to drink, byproducts of chlorine-based disinfection are harmful substances that pose a long-term public health risk. The provision of safe, reliable drinking water is fundamentally important. This study was published in Nature Sustainability on June 9. Yu Wenzheng's team from the Research Center for Eco-Environmental Science of the Chinese Academy of Sciences highlighted this risk and suggested sustainable solutions such as ozone biofiltration and nanofiltration to increase the safety of drinking water.
