WebDec 9, 2024 · upper threshold estimates of natural As background concentrations in the region were within the ranges of 11 mg/kg- 49mg/kg (Table 1 of Palmer et al. 2024). This conclusion supports the use of the CCME background concentration of 10 mg/kg for areas beyond 25 km of Yellowknife in the offsite HHRA. WebTotal aluminium concentrations for Canadian jurisdictions varied from below the detection limit (0.04 µg/L for Nova Scotia) to 58,500 µg/L for Alberta. The median (50 th percentile) was less variable, ranging from 6 µg/L for Ontario to 500 µg/L for Manitoba.
