But we haven't done enough national studies on where they show up in drinking water. So, we looked for 17 key PFAAs in drinking water from 79 cities across 31 regions in China. We wanted to see where they were and how they spread. We also checked what might affect their presence, things like nearby industries, population density, and GDP. Plus, we assessed the risks these contaminated water sources posed.<\/p>\n<p class=\"FR_fieldAcross China, the total PFAAs (all 17 combined) in drinking water ranged from 4.49 to 174.93 ng\/L, with an average of 35.13 ng\/L. Perfluorobutanoic acid (PFBA) was the most common, averaging 17.87 ng\/L. Then came perfluorooctanoic acid (PFOA) at 0.74 ng\/L, perfluorononanoic acid (PFNA) at 0.40 ng\/L, and perfluorooctane sulfonic acid (PFOS) at 0.25 ng\/L. Geographically, the highest PFAAs were in Southwestern China (57.67 ng\/L), then Eastern coastal China (32.85 ng\/L), Middle China (29.89 ng\/L), Northwestern China (28.49 ng\/L), and finally Northeastern China (22.03 ng\/L). Industrial areas generally had higher PFAA levels in their drinking water.<\/p>\n<p class=\"FR_fieldWe also saw different pollution levels based on city size: medium-sized cities had the most, followed by big cities, then towns. In towns, we found a clear link between population density and total PFAAs (R-2 = 0.45, p &lt; 0.01), as well as individual levels of PFHxA, PFBS, and PFOA (p &lt; 0.01). Good news, though: PFAA concentrations in drinking water from 28 provinces were below recommended advisories, except for Yunnan, Jiangsu, and Jiangxi. Those areas need more study to find the sources and figure out the potential health risks to people.<\/p>\n<p><a
