Research ArticleOpen accessIn the author namesLevels of Metals and Microbial Biomass in Cobalt Coleman Mine Tailings (Canada) Three Decades after Land ReclamationKabwe Nkongolo, Graeme Spiers et al.Investigations of restored metal contaminated tailings in Canada with regard to their long-term ability to sustain plant and associated microbiological populations are limited. The specific objectives of the present study were to assess (1) The current levels of total and bioavailable metals and (2) Microbial biomass in Cobalt Coleman mine tailings reclaimed in 1990. The level of microbial biomass was … …American Journal of Environmental Sciences, Vol. 19, Issue 1 · 20 Mar 2023 · 6,011 accessesView PDF Cite

Research ArticleOpen accessIn the author namesHEAVY METAL ANALYSIS IN RED OAK (QUERCUS RUBRA) POPULATIONS FROM A MINING REGION IN NORTHERN ONTARIO (CANADA): EFFECT OF SOIL LIMING AND ANALYSIS OF GENETIC VARIATIONAnh Tran, K. K. Nkongolo, M. Mehes-Smith et al.Understanding the dynamic of metals in soil and plants and population diversity in Northern Ontario is essential in determining progress toward ecosystem sustainability in reclaimed sites. The objectives of the present study were to assess the levels of metal content in soils and their accumulation in red oak plants from limed and unlimed sites. Genetic variation in red oak populations … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 25 Jun 2014 · 7,737 accessesView PDF Cite
