Adsorption of mercury(ll) and methylmercury by two tannin sorbents was investigated using radiotracers. High sorption capacities for mercury are registered for both sorbents at pH 7. For Eucaliptus Saligna Sm sorbent (ETS) the maximum sorption capacity was 1.2_+.0.2 mmol/g and for Lysiloma latisiliqua sorbent (LTS) was 8.5+0.2 mmol/g. Methylmercury adsorption maximum was recorded at pH 4 and in...

phenotypic and genotypic diversity as well as symbiotic effectiveness of twenty one symbionts isolated from nodules of four acacia species (acacia melanoxylon, a. mearnsii, a. saligna and acacia tortillis) grown in morocco were evaluated. growth in various media (yma, yma-bbt, yma-rc), colony morphology, tolerance to stress factors (temperature, ph, salt concentrations, various heavy metals) an...

The impacts of climate change are inevitable and driven by increased levels greenhouse gases (GHG) in the atmosphere, requiring mitigation re-adaptation measures. In this context, article critically analyzes influence drying technology type, forest biomass, GHG emissions resulting from energy required for agricultural crops, presenting a case study tobacco drying. study, increasing technologica...
