This work assessed the impact of polycyclic aromatic hydrocarbons (PAHs) on the polychaeta Marphysa sanguinea in Tunis Lagoon. Highest PAHs concentrations were accumulated at station E with maximum Σ PAH of 6028,87 ng/g DW. Changes in animal physiology were clearly related to bioaccumulated PAH. In fact, high levels of immune biomarkers (cyclooxygenase [COX] and lysozyme activity with maximum of 44631,10 FU/mn/mg protein and 0,017 lysozyme activity/mn/mg protein, respectively) were recorded at stations B and E. Triacylglycerol (TAG), the energy source, was lowest at the most polluted stations (E and B), while phospholipids (PL) were highest at the control station. Statistical analysis revealed a probable effect of both low and high molecular weight PAHs on variations in energy storage lipids (TAG and sterol and wax esters [SE/WE]) and membrane lipids, particularly PL. Our results encourage the use of M. sanguinea to assess pollution levels in coastal ecosystems.

The dead can talk: Investigating trace element and organic pollutant exposure in mammalian roadkill under contrasting habitats.
Environ Pollut

Centre for Environmental and Climate Science, Lund University, Sweden.
Urban environments are exposed to a substantial range of anthropic pressures, including chemical exposure. While trace metals and legacy pollutants have been well documented, the extent of wildlife exposure to emerging contaminants has received little attention, in terrestrial mammals. Concentrations of trace elements (Ag, Al, As, Cd, Co, Cr, Cu, Fe, Mn, Pb and Zn) and 48 organic pollutants (Polychlorinated Biphenyls: PCBs, Organochlorine Pesticides: OCPs, Polycyclic Aromatic Hydrocarbons: PAHs, phthalates and pyrethroid pesticides) were measured in tissues of European hedgehogs (Erinaceus europaeus) in southern Sweden.

Diesel exhaust particles (DEPs) are atmospheric pollutants associated with adverse health effects. In response to their impact, natural gas (NG) has emerged as a promising alternative fuel due to its cleaner combustion. Although the cytotoxicity and genotoxicity of DEPs from diesel or NG engines have been extensively studied, the impact of dual natural gas-diesel systems remains unexplored.

Background: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants that can cause a variety of health problems. This study sought to determine whether there was a relationship between PAHs and current asthma in adults.
Methods: This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2016 and employed multifactor logistic regression, subgroup analyses, and smoothed curve fitting to examine the linear and nonlinear associations between PAHs and current asthma.
Tunnel wash water in a cold climate: characteristics, ecotoxicological risk, and effect of sedimentation.

Department of Civil and Environmental Engineering, Norwegian University of Science and Technology, S. P. Andersens Veg 5, 7031, Trondheim, Norway.
The characterization of tunnel wash water (TWW) from 12 Norwegian tunnels showed very high concentrations of total suspended solids (TSS), metals, and polycyclic aromatic hydrocarbons (PAHs). Iron (Fe), aluminum (Al), and manganese (Mn) were mainly particle-associated. They are efficiently removed by sedimentation, while the dissolved concentrations of toxic metals like Cu, Zn, and As did not change.

Organic anode materials have garnered attention for use in rechargeable Li-ion batteries (LIBs) owing to their lightweight, cost-effectiveness, and tunable properties. However, challenges such as high electrolyte solubility and limited conductivity, restrict their use in full-cell LIBs. Here, we report the use of highly crystalline Cl-substituted contorted hexabenzocoronene (Cl-cHBC) as an efficient organic anode for full-cell LIBs.
