Silurian and Devonian source rocks and crude oils from the western part of Libya: Organic geochemistry, palynology and carbon stratigraphy

, 2015
The Early Silurian “hot” shales and Late Devonian black shales are major regional oil and gas source rocks in North Africa. Their deposition probably played a major role in global carbon cycling in general because of the large areas of the ocean affected.

Microbial Community Dynamics in Marine Water: Influence of Hydrocarbon Type and Exposure Time

Environmental Toxicology, EarlyView.
ABSTRACT Marine environments are frequently impacted by petroleum‐derived hydrocarbons, which pose ecological risks because of their toxic, mutagenic, and carcinogenic potential. Microorganisms play a crucial role in hydrocarbon degradation, and understanding the influence of time and hydrocarbon type on microbial dynamics helps improve bioremediation ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Oxidative Stress Biomarkers in the Shrimp Macrobrachium amazonicum (Heller, 1862): Assessment in an Environmental Preservation Area in the Brazilian Amazon

Environmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities generate a significant amount of pollutants that are released into the environment, causing physiological and ecological disturbances. Among the xenobiotics present in aquatic ecosystems, numerous chemical and organic compounds have oxidative potential or are metabolized through oxidative processes, which may amplify ...

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 ...

Chrysin Mitigates Acetamiprid‐Induced Testicular Injury in Mice via Suppression of Endoplasmic Reticulum Stress and Inflammation

Environmental Toxicology, EarlyView.
ABSTRACT Acetamiprid (ACP) is a neonicotinoid pesticide that is extensively utilized for the management of insect populations, but its toxic effects on the male reproductive system have become a source of concern. Chrysin (CHR) is a natural flavone found in many plants and bee products, including honey and propolis.
