Substrate Specificity and Structural Characteristics of the Novel Rieske Nonheme Iron Aromatic Ring-Hydroxylating Oxygenases NidAB and NidA3B3 from Mycobacterium vanbaalenii PYR-1

mBio, 2010
The Rieske nonheme iron aromatic ring-hydroxylating oxygenases (RHOs) NidAB and NidA3B3 from Mycobacterium vanbaalenii PYR-1 have been implicated in the initial oxidation of high-molecular-weight (HMW) polycyclic aromatic hydrocarbons (PAHs), forming cis-

Soil polychemical contamination on Beliy Island as key background and reference plot for Yamal region

Polish Polar Research, 2017
Background concentrations of main trace elements and polycyclic aromatic hydrocarbons (PAHs) were investigated in pristine soils of the Beliy Island situated in the Kara Sea, Yamal autonomous region, North-West Siberia, Russia. Belyi Island is considered

Occurrence and fate of PTE, PAH, and PFAS trace contaminants in soils and river suspended particulate matter in three DANUBEAN river catchments. [PDF]

J Environ Qual
Abstract This study aimed to investigate the occurrence and concentration patterns of three groups of trace contaminants—potentially toxic elements (PTEs), polycyclic aromatic hydrocarbons (PAHs), and per‐ and polyfluoroalkyl substances (PFASs)—in river catchments with contrasting land use and landscape characteristics. A second objective was to relate

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Source apportionment of elevated wintertime PAHs by compound-specific radiocarbon analysis [PDF]

Atmospheric Chemistry and Physics, 2009
Natural abundance radiocarbon analysis facilitates distinct source apportionment between contemporary biomass/biofuel (¹⁴C "alive") versus fossil fuel (¹⁴C "dead") combustion.
