Crynodeb
| Disgrifiad |
English: Figure 1 Geographical distribution of global populations at risk of exposure to chemical contamination in drinking water, as reported in the literature (54, 55, 62–80). We present only population estimates that (a) consider a contamination level threshold greater than or equal to the World Health Organization maximum recommended contaminant limit (WHO MCL) and guideline values presented in Table 1 and (b) for which the estimated population at risk of exposure exceeds 50,000. For total dissolved solids (TDS), which have no health-based WHO MCL or guideline value, the US Environmental Protection Agency guideline is used. Further considerations are discussed in the Supplemental Material, which includes a table of exposed population estimates by country and contaminant. |
