“…This may be due to issues related to creatinine correction (Barr et al 2005), and, particularly for NHANES 1999–2002, noise introduced to the urinary concentration estimates by molybdenum interference and the correction for that interference (NCHS 2005; Suzuki et al 2008). We considered the possibility that, by chance, the smaller associations for urinary cadmium emanated from characteristics of the one-third sub-sample of participants who were in the urinary cadmium analyses.…”

Background It is unclear whether environmental cadmium exposure is associated with cardiovascular disease, although recent data suggest associations with myocardial infarction and peripheral arterial disease. Objective The objective of this study was to evaluate the association of measured cadmium exposure with stroke and heart failure (HF) in the general population. Methods We analyzed data from 12,049 participants, aged 30 years and older, in the 1999–2006 National Health and Nutrition Examination Survey (NHANES) for whom information was available on body mass index, smoking status, blood cotinine level, alcohol consumption, and socio-demographic characteristics. Results At their interviews, 492 persons reported a history of stroke, and 471 a history of HF. After adjusting for demographic and cardiovascular risk factors, a 50% increase in blood cadmium corresponded to a 35% increased odds of prevalent stroke [OR: 1.35; 95% confidence interval (CI): 1.12–1.65] and a 50% increase in urinary cadmium corresponded to a 9% increase in prevalent stroke [OR: 1.09; 95% CI: 1.00–1.19]. This association was higher among women [OR: 1.38 95% CI: 1.11–1.72] than men [OR: 1.30; 95% CI: 0.93–1.79] (p-value for interaction=0.05). A 50% increase in blood cadmium corresponded to a 48% increased odds of prevalent HF [OR: 1.48; 95% CI: 1.17–1.87] and a 50% increase in urinary cadmium corresponded to a 12% increase in prevalent HF [OR: 1.12; 95% CI: 1.03–1.20], with no difference in sex-specific associations. Conclusions Environmental exposure to cadmium was associated with significantly increased stroke and heart failure prevalence. Cadmium exposure may increase these important manifestations of cardiovascular disease.

“…The potential of Presep ® PolyChelate, on which CM-PEI is immobilized as a functional group, was compared to those of the other commercially available chelating resins, including Nobias Chelate-PA1, [28][29][30][31][32][33][34][35][36][37][38] 27 The extraction capacities for Cu was 0.30 mmol g -1 for Presep ® PolyChelate; this value was 2 times larger than that for Nobias Chelate-PA1, whereas it was smaller than those for the other chelating resins. In the investigation of the effect of pH on the recoveries of 21 kinds of elements, Fig.…”

“…28-38 Such performance is desirable for the analyses of real samples, which contain large amounts of alkaline earth elements; this resin has been applied for the separation and preconcentration of some elements in environmental [28][29][30][31][32][33][34][35][36] and biological 37,38 samples. We have studied the usefulness of polymer/oligomer ligands for the separation and preconcentration of elements and have found that α-pyridylamino oligomer 39 and polythioamides [40][41][42] showed interesting performance, indicating that polymer/ oligomer ligands have the possibility of improving selectivity and efficiency in the extraction of elements.…”
