heavy metals

Industrial by-products are stored in large quantities in the open, leading to wasted resources and environmental pollution, and the natural environment is similarly faced with phosphate depletion and serious water and soil pollution. This study uses these by-products to produce a new sludge/biomass ash ceramsite that will be used to adsorb nitrogen and phosphorus from […]

In mineral-rich areas, eutrophic lakes are at risk of HMs pollution. However, few papers focused on the repair of HMs in eutrophic environment. Our study analyzed multiple forms of HMs, pore structure and microbial responses in the water-sediment system of eutrophic lake treated with biochar, Effective Microorganisms (EMs) or/ and microplastics (MPs). As biochar provided […]

Environmental pollution caused by increasing levels of heavy metals (HM) is a pressing problem throughout the world. Phytoremediation is considered a prospective remediation approach for HM-contaminated soil, but more research is required to enhance remediation efficiency. Biochar is a promising bio-residue material that can be used for the sustainable remediation of heavy metal-contaminated soil. In […]

Though public awareness is low, some scientists believe “biochar” is quietly becoming the world’s first major carbon removal success story. The waste coffee husks that come out of Synergie Nord Sud (SNS), Cameroon’s largest coffee-processing plant, are no longer left to gradually decompose in a landfill. Instead, these tons of biomass are now transported to […]

Dear Tee Cee, What exactly is “biochar”? I see it for sale and talked about as a good thing. How is it made, and what do people do with it? It seems to be some sort of wood-burning process, so I don’t understand how that can be good for the environment. — Laura Dear Laura, […]

Abstract Soil amendment with biochar alleviates the toxic effects of heavy metals on microbial functions in single-metal contaminated soils. Yet, it is unclear how biochar application would improve microbial activity and enzymatic activity in soils co-polluted with toxic metals. The present research aimed at determining the response of microbial and biochemical attributes to addition of […]
