AI Article Synopsis
- - The study focuses on heavy metal pollution in the El Jadida region of Morocco’s Atlantic coastline, assessing the health of coastal ecosystems and human health risks through metal bioaccumulation in a common species, Phorcus lineatus.
- - Two polluted sites, Haouzia (H) and Jorf-Lasfar (J), were examined, with samples collected monthly to measure trace metal concentrations in the soft tissues of the snails.
- - Results indicated significant variations in bioaccumulation, with Jorf-Lasfar exhibiting higher levels of metals like Cadmium, Zinc, Iron, and Copper, leading to a notably higher Metal Pollution Index compared to Haouzia, especially in autumn.
Article Abstract
Heavy metals in coastal ecosystems represent an issue for human and environmental health worldwide. The objective of this study was to assess the state of health of Morocco's Atlantic coastline in the El Jadida region. The study was based on metal bioaccumulation in Phorcus lineatus, a species common to Atlantic coasts. Two polluted sites were selected: Haouzia (H) and Jorf-Lasfar (J). Animals were sampled monthly for determination of trace metals in the soft tissues of P. lineatus. Except for Cr, the results show a significant variation in bioaccumulation. The highest concentrations (μg g dry weight) were found in individuals from J, with 10.68 ± 2.43 Cd, 107.36 ± 21.15 Zn, 666.55 ± 143.34 Fe and 184.47 ± 49.80 Cu. The maximum Metal Pollution Index value was 37.06 at site H in spring and 65.96 at site J in autumn. The J site appears significantly more polluted than H site.

Aquatic toxicology, as a result of industrial and agrieqcultural effluences, has become a global concern impacting not only the well-being of aquatic organisms but human health as well. The current study evaluated the impact of four toxic trace elements (TTEs) Cadmium (Cd), copper (Cu), lead (Pb), and nickel (Ni) in three organs (liver, gills, and muscles) of five fish species viz, Rita rita, Sperata sarwari, Wallago attu, Mastacembelus armatus, and Cirrhinus mrigala collected from right and left banks of Punjnad headworks during winter, spring, and summer. We investigated the accumulation (mg/kg) of these TTEs in fish in addition to the human health risk assessment.

These metal-herbicide interactions have inevitable but remarkable effects on insects, which remain poorly understood. Here, we examined the effects of the interactions among zinc (Zn), iron (Fe), and paraquat (PQ) at a sublethal dose on the physiological response of the Egyptian cotton leafworm .

This study investigated the elemental composition of , addressing the gap in comprehensive trace element profiling of this medicinal plant. The research aimed to determine the distribution of macronutrients, micronutrients, and beneficial and potentially toxic elements across different plant parts (seeds, leaves, stems, and roots). Using ICP-OES analysis, two digestion methods were employed to capture both complex and labile elements.

Since the biological activities and toxicities of 'foreign' and/or excess levels of metal ions are predominantly determined by their precise molecular nature, here we have employed high-resolution H NMR analysis to explore the 'speciation' of paramagnetic Ni(II) ions in human saliva, a potentially rich source of biomolecular Ni(II)-complexants/chelators. These studies are of relevance to the corrosion of nickel-containing metal alloy dental prostheses (NiC-MADPs) in addition to the dietary or adverse toxicological intake of Ni(II) ions by humans. Unstimulated whole-mouth human saliva samples were obtained from n = 12 pre-fasted (≥8 h) healthy participants, and clear whole-mouth salivary supernatants (WMSSs) were obtained from these via centrifugation.
