According to the results, the concentration of Pb in water in December at sampling points B and C was 0.012 mg / l, a value that is above the maximum permissible limit of national legislation; on the other hand, the results of Pb in sediment registered the highest concentration at the sampling point C in October, with 1,736 mg / Kg /; the lowest was recorded at sampling point B in December, with 0.272 mg / Kg, confirming that the values are below the permitted level of Canadian regulations. |
