Authigenic aragonite preserves a carbon isotopic record of heterotrophic microbial influences on dissolved inorganic carbon (DIC) in microenvironments within shallow subtidal stromatolites from Highborne Cay, Bahamas. A greater amount of aragonite precipitates when and where respiration, rather than photosynthesis, influences local DIC, which is consistent with sulfate reduction promoting carbo...

The anthropogenic inputs of Rh in the environment-together with other platinum group elements-have increased considerably during the last 20-30 years. However, thermodynamics and kinetics on the interaction of Rh with natural organic and inorganic ligands are still poorly characterized. Here, we report the time-dependent speciation of rhodium chlorides spiked to model freshwater with and withou...

Water treatment technologies are needed that can convert per- and polyfluoroalkyl substances (PFAS) into inorganic products (e.g., CO2, F−) less toxic than parent PFAS compounds. Research on electrochemical processes such as electrocoagulation electrooxidation has demonstrated proof-of-concept removal destruction. However, research primarily been conducted in laboratory matrices electrochemical...

Sorption is currently a promising method for purifying wastewater from organic and inorganic substances. The authors have developed technology obtaining granular composite sorbent (GCS), on the basis of large-tonnage production waste - tobacco dust. However, as result sorption purification highly concentrated food industry enterprises, significant amount formed, regeneration which economically ...

The limiting factor towards the utilization of Mg and its alloys especially in aqueous environment is their low corrosion resistance occasioned by high chemical reactivity electron negative potential. inhibitor technology one effective mitigation approaches. In this review, inorganic, organic (surfactants, ionic liquids, Schiff bases), polymeric substances reported as inhibitors for are discuss...

Benthic amphipod, Grandidierella japonica widely inhabits the Korean coastal waters and is developed as a standard test species for sediment toxicity tests. We exposed G. japonica to various pollutants including 4 kinds of inorganic metals (Ag, Cd, Cu and Hg), tributyltin [TBT], ammonia and 7 polycyclic aromatic hydrocarbon (PAH) compounds (acenaphthene, chrysene, fluoranthene, fluorene, naphth...

The International Agency for Research on Cancer recently classified inorganic lead as a probable carcinogen, while organic lead remained unclassifiable. Uncertainty persists because of limited epidemiologic evidence. The authors addressed the relation between occupational exposure to lead and the risk of 11 types of cancer among men in a case-control study conducted in Montreal, Quebec, Canada,...
