Abstract:
The Standards for drinking water quality(GB 5749-2022), which has taken effect on April 1, 2023, stipulates that limit values of aesthetic and chemical characteristics of drinking water can be temporarily adjusted in emergencies. However, the national standard does not clearly specify the adjusted period and limit values. This study is based on the principle that the human body will not cause acute toxic damage during short-term exposure, considering the acceptability such as chromaticity, smell, and taste in drinking water, referring to the drinking water quality standards of different countries and regions including the World Health Organization, the United States, the European Union, Japan, Australia, etc. We discussed the limited values during emergencies for 21 aesthetic and chemical characteristics from GB 5749-2022 to guaranine the drinking water safety and human health in emergencies.
