Lead (Pb) Persons caught in the initial WTC-related dust cloud experienced brief exposures to high Pb levels based on analyses of deposited dust samples. In late September 2001, air Pb concentrations at the WTC perimeter sites reached 1.5 μg/m 3 on some days, that is, significantly greater than urban background levels in U.S. cities.

In order to assess the potential of wetland plants to remediate metals from a paper mill effluent contaminated wetland site in Northeast India, 25 abundant plant species belonging to 15 different families, soil, and water samples from the sites were tested for Pb, Zn, Mg, and Fe by atomic absorption spectrophotometer. The results showed that metal accumulation by wetland plants differed among

The mill was commissioned in the first half of 1988 at a rate of 320 000 tonnes per annum. An expansion in the latter half of 1989 has since increased production to 550 000 tonnes per annum. The initial geological resource at the commencement of mining was 3.8 million tonnes at 13.5 per cent Zn and 4.4 per cent Pb.

The equivalency formula is Ag g/t+44.6*Pb%+43.5*Zn% using prices of $19/oz Ag, $1.00/lb Pb and $1.25/lb Zn and estimated recoveries of 77% Ag, 86% Pb, and 83% Zn. Drilling results up to December 31, 2017. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The numbers may not compute exactly due to rounding.
