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.

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 ...

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 ...

Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Form (III) of artemisinin: discovery and crystallographic characterization of a new high‐pressure polymorph

Acta Crystallographica Section B, EarlyView.
The polymorphic behaviour of the three forms of artemisinin was investigated using single‐crystal X‐ray diffraction in a diamond anvil cell, with notable observation of a pressure‐induced phase transition from form (II) to form (III).Artemisinin (ART) is mainly used for the treatment of malaria and exhibits polymorphism with two known crystalline forms.
