“…While the main source of tungsten exposure is occupational via inhalation of hard metal dust, the general population may be exposed through drinking water, food, or industrial releases into the environment [110, 111]. The elimination time of tungsten in most tissues, except bone, is 5 days (70% of the dose) and 100 days (30% of the dose).…”

Published systematic reviews concluded that there is moderate to strong evidence to infer a potential role of lead and cadmium, widespread metal exposures, as cardiovascular risk factors. For other non-essential metals, the evidence has not been appraised systematically. Our objective was to systematically review epidemiologic studies on the association between cardiovascular disease in adults and the environmental metals antimony, barium, chromium, nickel, tungsten, uranium, and vanadium. We identified a total of 4 articles on antimony, 1 on barium, 5 on chromium, 1 on nickel, 4 on tungsten, 1 on uranium and 0 on vanadium. We concluded that the current evidence is not sufficient to inform on the cardiovascular role of these metals because the small number of studies. Few experimental studies have also evaluated the role of these metals in cardiovascular outcomes. Additional epidemiologic and experimental studies, including prospective cohort studies, are needed to understand the role of metals, including exposure to metal mixtures, in cardiovascular disease development.

This study describes the hydrogeochemistry and distributions of As in groundwater from a newly investigated area of Burkina Faso. Groundwaters have been sampled from handpumped boreholes and dug wells close to the town of Ouahigouya in northern Burkina Faso.Although most analysed groundwaters have As concentrations of less than 10 µg L -1 , they have a large range from <0.5 to 1630 µg L -1 . The highest concentrations are found in borehole waters; all dug wells analysed in this study have As concentrations of <10 µg L -1 .Skin disorders (melanosis, keratosis and more rare skin tumour) have been identified among the populations in three villages in northern Burkina Faso, two within the study area.Although detailed epidemiological studies have not been carried out, similarities with documented symptoms in other parts of the world suggest that these are likely to be linked to high concentrations of As in drinking water. The high-As groundwaters observed derive from zones of gold mineralisation in Birimian (Lower Proterozoic) volcano-sedimentary rocks, the gold occurring in vein structures along with quartz and altered sulphide minerals (pyrite, chalcopyrite, arsenopyrite). However, the spatial variability in As concentrations in the mineralised zones is large and the degree of testing both laterally and with depth so far limited. Hence, concentrations are difficult to predict on a local scale. From available data, the groundwater appears to be mainly oxic and the dissolved As occurs almost entirely as As(V) although concentrations are highest in groundwaters with dissolved-oxygen concentrations <2 mg L -1 . The source is likely to be the oxidised sulphide minerals and secondary iron oxides in the mineralised zones. Positive correlations are observed between dissolved As and both Mo and W which are also believed to be derived from ore minerals and oxides in the mineralised zones. The discovery of high As concentrations in some groundwaters from the Birimian rocks of northern Burkina Faso reiterates the need for reconnaissance surveys in mineralised areas of crystalline basement.

“…Equation (2) demonstrates that the relationship is the same for tap water that is consumed. The correspondence between arsenic and tungsten is expected, based on previously observed associations between dissolved arsenic and tungsten concentrations in groundwater (Grimes et al 1995) and ore deposition patterns (Kesler et al 2003) in the Great Basin region of the United States. It also corresponds closely with observed correlations between As and W in groundwater in ) concentrations in samples of tap water reported to be consumed or not consumed.…”

Arsenic, As(III), and tungsten in Nevada County's private water supplies

In parts of the western United States groundwater used for drinking water contains high concentrations of metals, including arsenic. In a rural county in Nevada, USA, we measured concentrations of arsenic and tungsten and the proportion of arsenic occurring in trivalent form (As (III) ) in tap water samples from private domestic wells in 307 households. The proportion of arsenic occurring as As (III) ranged from 0 to 100% (ave. 21%, median 1% This suggests that householders in this area were likely to be exposed to both metals simultaneously, given that 253/307 of the respondents (82%) reported consuming tap water.
