摘要:
系统介绍了我国《生活饮用水卫生标准》（GB 5749—2022）中的异味和新污染物指标，并与部分发达国家和地区（美国、加拿大、澳大利亚、新西兰、新加坡和日本）的相关标准进行对比。关于异味指标，我国首次将土臭素和2-甲基异莰醇列为强制指标，是继日本之后世界上第二个将其列为强制水质指标的国家。同时，我国也是第一个将二甲基二硫醚和二甲基三硫醚列为水质参考指标的国家，有助于提高供水行业相关异味物质的检测能力。通过对比异味阈值和指标限值，发现有12种物质的限值浓度或其氯消毒副产物高于其对应异味阈值，即相关污染物浓度虽然满足水质标准，但仍可能使饮用水产生异味。对于新污染物，我国最新的水质标准中共包含8种物质，约占全球主要国家或地区相关标准纳入总数（12种）的67%，居世界首位。将新污染物纳入各国水质标准是未来发展的大趋势，但相关指标和限值还有待进一步优化。
Abstract:
This paper provides a detailed discussion on the odorant and emerging contaminant items listed in the Standards for Drinking Water Quality （GB 5749-2022） in China, comparing them with standards from the United States, Canada, Australia, New Zealand, Singapore, and Japan. Regarding odorants, China has included geosmin and 2-methylisopropanol as mandatory items in the water quality standars for the first time, becoming the second country after Japan to list them as compulsory water quality indicators. In addition, China is the first country to include 2-methyl disulfide and 2-methyl trisulfide as reference indicators in its drinking water quality standard, a significant step towards enhancing the monitoring of relevant odorants in China’s water supply industry. The latest Chinese standard includes 12 chemical items with limit concentrations or their DBPs significantly higher than their corresponding odor threshold levels, meaning that while their concentrations may meet the standard, they could still cause odor issues in drinking water. Relating emerging contaminants, there were eight emerging contaminants listed in the latest drinking water quality standard of China, while there were twelve emerging contaminants have been listed in the standards of all countries or regions. The former accounted for 67% of the latter, which ranked the first. The inclusion of emerging contaminants in drinking water quality standards is a growing global trend, but the related items and limit concentrations should be more precisely defined.
