Summary: Polycyclic aromatic hydrocarbons (PAHs), particularly chrysene, have toxic effects on the liver by increasing relative liver weight and elevated serum ALT levels; the hepatotoxicity of chrysene is dependent on the aryl hydrocarbon receptor (AhR), while Nrf2 plays a crucial role in protecting against oxidative liver injury induced by chrysene.

Summary: This study tested six field cleaning techniques on metal sampling equipment and found that protocols containing a solvent step were more effective than protocols without solvents in reducing chemical carryover. Depending on the data quality objectives, the differences may not be meaningful, and choosing a cleaning technique should be governed by health, safety, and environmental factors.

Summary: Tire granulates recovered from end-of-life tires contain a complex mixture of toxic polyaromatic compounds (PACs), which are only partially monitored. This study used chemical analysis and bioassays to determine PAC concentrations and activities in tire granulates, revealing the presence of unknown bioactive compounds that contribute significantly to the effects observed. Further investigations are needed to identify and apportion these toxicants.

Summary: Bivalve mollusks, including oysters, have a high susceptibility to accumulating lipophilic organic contaminants, such as polycyclic aromatic hydrocarbons (PAHs), due to their low metabolic potential. The consumption of oysters, which are known to have high levels of PAHs, can pose a serious public health concern in areas with high PAH contamination. This study presents a method to detect and locate complex mixtures of PAHs in oyster tissues using fluorescent immunohistochemistry, providing valuable insights into the internal partitioning mechanisms of PAH-exposed oysters and potential applications for studying PAH distribution in other organisms.

Summary: Petroleum refineries produce oily sludge containing hazardous polycyclic aromatic hydrocarbons (PAH), and its proper disposal is a major concern. Analyzing the physicochemical properties and functions of indigenous microbes at contaminated sites is crucial for determining the bioremediation strategy. This study examines these parameters at two geographically distant sites with different crude oil sources and compares the metabolic capability of soil bacteria based on contamination sources and site age. The results show that petroleum hydrocarbon-derived organic carbon and total nitrogen negatively impact microbial diversity.

Summary: In recent years, there has been significant progress in the study of thermal transformation of waste into valuable materials such as biochar. High-temperature processes can lead to the formation of toxic polycyclic aromatic hydrocarbons (PAHs). However, the pyrolysis process can also result in the formation of derivatives containing oxygen, nitrogen, or sulfur, which may have higher toxicity than parent PAHs. The bioavailability of PAHs is an important parameter in the agricultural application of carbonaceous materials.

Summary: This study investigated the use of graphene oxide-immobilized bacterial pellets for the removal of polycyclic aromatic hydrocarbons (PAHs) from contaminated soil. The results showed that these immobilized bacterial pellets significantly improved the removal rate of PAHs and enhanced the abundance of degrading bacteria in the soil. They also enriched potential indigenous degrading bacteria and functional genes involved in PAHs degradation. Overall, this nanocomposite bacterial pellets provide a novel microbial immobilization option for remediating organic pollutants in harsh soil environments.

Summary: Phytoremediation is a promising and sustainable strategy for recovering soils contaminated with Potentially Toxic Elements (PTEs), with polyculture plants showing better efficiency in pollutant phytostabilization. Among the plant species, Festuca performed the best due to the overexpression of metal transporters, leading to a site-specific bio-factory for relatively fast recovery of large contaminated areas.

Summary: The geochemical composition of bedrock is the key factor determining elemental concentrations in soil, while anthropogenic factors have a lesser impact. In this study, soil samples from Cosenza and Rende in southern Italy were analyzed for elemental concentrations to identify the sources and define soil quality. The results showed that soil elemental associations were controlled by chemical and mineralogical factors, as well as soil-forming processes.

Summary: The study investigates the relationship between fault system and nonvolcanic gas vents in the south-eastern sector of the Matese Massif in Italy. Through a multidisciplinary approach, the researchers reconstruct the structural architecture of the area and conclude that young normal faults play a crucial role in gas migration. The results from CO2 flux and geoelectrical surveys support this understanding and indicate that the NW-SE striking fault is the primary pathway for gas migration.

Summary: This study evaluates the contamination level of potentially toxic elements (PTEs) in the stream sediments of the Nile River. The results show that elements like Cr, Mn, V, and Fe have a natural origin, while Cu, Ni, Co, and As are linked to both natural and anthropogenic processes. The sequential extraction analysis reveals that Mn, Co, Ni, and in some sites, Cu and Zn, are the most bioavailable elements, posing a high risk of toxicity.
