Environmental Toxicology and Chemistry, Volume 43, Issue 6, Page 1195-1241, June 2024.Abstract Birds are used as bioindicators of environmental mercury (Hg) contamination, and toxicity reference values are needed for injury assessments. We conducted a comprehensive review, summarized data from 168 studies, performed a series of Bayesian hierarchical meta‐analyses, and developed new toxicity reference values for the effects of ...

Global Change Biology, Volume 30, Issue 5, May 2024.We investigated the impact of melting glaciers and wastewater in the Arctic on the aquatic resistome. Plasmids, small genetic carriers known for transferring antibiotic resistance genes among bacteria were our target. By studying these genetic elements in glacial ice and nearby waters of Svalbard, we uncovered the presence of the unique as well ...

Aspects of secondary bonding intramolecular interaction in organomercury and organochalcogen derivatives [PDF]
, 2011 Recent trends in the area of intramolecularly coordinated organomercury and organochalcogens derivatives are reviewed. Intramolecular coordination in organomercury derivatives facilitates the formation of mercurametallamacrocycle and leads to novel metal-

Synthesis, antimicrobial activity, computational and modeling studies of some new organotellurium compounds containing azo moities [PDF]
, 2015 A new series of organonotellurium compounds containing azo groups were prepared by new and convenient methods. Reaction of 1-(4-mercuric chloride-2,3-dichlorophenyl)-2-chloro diazine (4) with 8-hydroxyquinoline (5) gave the new organomercury compound 6 ...

Bioluminescence biosensor for the detection of organomercury contamination
, 2014 To selectively detect organomercurial compounds in the environment, in this study a bioluminescence biosensor for organomercurials was developed using a bacterial gene expression system for the mercury resistance determinant. merB(3)-Luciferase (mer-lux)
