Cadmium versus phosphate in the world ocean
WebApr 15, 2024 · Cadmium concentrations and isotope compositions are reported for the water column of the ETSP from 12 coastal, nearshore and offshore stations between 4°S and 14°S. The data reveal several distinct aspects of the marine biogeochemical cycling of Cd and Cd isotopes that are important for low oxygen environments. WebLow-level cadmium exposure has adverse effects on chronic kidney disease (CKD); however, the risk factors for elevated blood cadmium levels (BCLs) have not been studied in CKD. We conducted a cross-sectional investigation in 200 CKD patients and stratified them by the tertiles of BCL to compare their demographic, environmental, and …
