Protection from heavy metals is a problem that has not been solved in a satisfactory manner so far. Usage of complexing agents in therapy of exposed workers results in both favorable outcome and recognized adverse effects. In the field of environmental protection, they cannot be used in practice, meaning that the risk of escape of metal pollutant from factory premises and their attack on the environnement remains present. The age of chemistry ('Chemistry, key to better living') has led to potent development of industry producing, at the same time, major problems induced by diffusion of metal pollutants, the nightmare of our times, like Camus' 'Plague'. According to the available results, it remains to be answered whether magnesium may influence this important problem, i.e. is this approaches the issue justifiable?

This study investigates the concentration of heavy metals lead (Pb), cadmium (Cd), and zinc (Zn) in the blood of house sparrows (Passer domesticus) across various urban habitats in Meknes, Morocco. Fifty adult sparrows were captured from five distinct sites, including industrial, high-traffic, and rural areas. Blood samples were specifically analyzed for Pb, Cd, and Zn using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES).

Context: To address the severe fuel crisis and environmental pollution, the use of lightweight metal materials, such as AZ alloy, represents an optimal solution. This study investigates the mechanical behavior and deformation mechanism of AZ alloys under uniaxial compressive using molecular dynamics (MD) simulations. The influence of various compositions, grain sizes (GSs), and temperatures on the compressive stress, the ultimate compressive strength (UCS), compressive yield stress (CYS), Young's modulus (E), shear strain, phase transformation, dislocation distribution, and total deformation length is thoroughly examined.

This work focused on the biotreatment of wastewater and contaminated soil in a used oil recycling plant located in Bizerte. A continuous stirred tank reactor (CSTR) and a trickling filter (TF) were used to treat stripped and collected wastewater, respectively. The CSTR was started up and stabilized for 90 days.

Background: Over 250 million children are developing sub-optimally due to their exposure to early life adversities. While previous studies have examined the effects of nutritional status, psychosocial adversities, and environmental pollutants on children's outcomes, little is known about their interaction and cumulative effects.
Objectives: This study aims to investigate the independent, interaction, and cumulative effects of nutritional, psychosocial, and environmental factors on children's cognitive development and mental health in urban and rural India.
