In the present study, we showed the references level of food cadmium intake (FCd) and total cadmium intake (TCd) for renal dysfunction by using benchmark dose (BMD) approach. 342 subjects living in a control and a cadmium polluted area were included in this study. The FCd, TCd and cadmium in urine (UCd) and blood (BCd) were calculated or determined. Urinary \u03b2<jats:sub>2<\/jats:sub>Microglobulin (UBMG) was determined as indicator of renal function. The median FCd, TCd, UCd and BCd were 1.4\u2009g, 1.4\u2009g, 3.1\u2009\u03bcg\/g creatinine(cr) and 1.3\u2009\u03bcg\/L in control and 3.3\u2009g, 3.6\u2009g, 13.5\u2009\u03bcg\/g cr and 12.1\u2009\u03bcg\/L in polluted area. The 95% lower confidence bounds of BMD (BMDLs) of FCd for renal dysfunction were 1.36\u20131.55\u2009g (BMR\u2009=\u200910%) and 0.88\u20131.11\u2009g (BMR\u2009=\u20095%). The BMDLs of TCd were 1.29\u20131.46\u2009g (BMR\u2009=\u200910%) and 0.73\u20130.95\u2009g (BMR\u2009=\u20095%). FCd and TCd are valuable markers for the predication of renal dysfunction induced by cadmium. The BMDLs of FCd were close to previous report in Japan and the BMDLs of TCd were lower than the critical standard previously reported, in particular at BMR of 5% which can be interpreted as representing the influence of smoking.<\/jats:p>","DOI":"10.1038\/s41598-018-27411-3","type":"journal-article","created":{"date-parts":[[2018,6,7]],"date-time":"2018-06-07T09:28:56Z","timestamp":1528363736000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["The references level of cadmium intake for renal dysfunction in a Chinese population"],"prefix":"10.1038","volume":"8","author":[{"given":"Xiao","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongqiu","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoying","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoqiang","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taiyi","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2018,6,13]]},"reference":[{"key":"27411_CR1","first-page":"133","volume":"4","author":"G Nordberg","year":"1996","unstructured":"Nordberg, G.
