Monohydrocalcite: a promising remediation material for hazardous anions

Monohydrocalcite: a promising remediation material for hazardous anions.

The formation conditions, solubility and stability of monohydrocalcite (MHC, CaCO3·H2O), as well as sorption behaviors of toxic anions on MHC, are reviewed to evaluate MHC as a remediation material for hazardous oxyanions. MHC is a rare mineral in geological settings that occurs in recent sediments in saline lakes. Water temperature does not seem to be an important factor for MHC formation. The...

Methanotrophs: promising bacteria for environmental remediation

Methanotrophs are unique and ubiquitous bacteria that utilize methane as a sole source of carbon and energy from the atmosphere. Besides, methanotrophs may also be targeted for bioremediation of diverse type of heavy metals and organic pollutants owing to the presence of broad-spectrum methane monooxygenases enzyme. They are highly specialized group of aerobic bacteria and have a unique capacit...

Innovative Methods for the Assessment of Hazardous Waste on Remediation

The hazardous waste remediation process is completed through multiple phases each served by differing professions. First, geologists, hydrogeologists, the EPA and consultants complete a site assessment and investigation at a potential hazardous waste site. The environmental engineering and consulting professionals are then responsible for providing design services. Finally, construction profess...

Aiding Route Decision for Hazardous Material Transportation

This research attempts to build a framework for determination of optimal routes for hazardous material transportation. Previous works have suggested incorporation of many conflicting objectives in the analysis, such as travel cost, population exposure, environmental risk or security concerns. Multiplying the number of objectives leads to complex shortest path problems that often have several ef...
