Re-using an oleic by-product in the manufacturing of fired clay bricks.

Background: The high demand for building bricks underscores their essential role in the construction industry, which pushes researchers to continuously improve the characteristics of these products. This study aimed to investigate the impact of incorporating oleic components (Margins) in fired bricks manufacturing of by substituting water with different percentages of margins.

Methods: Fired bricks were produced at the laboratory using clays taking from the Tangier region in northern Morocco.

Distribution, ecological, and health risk assessment of trace elements in the surface seawater along the littoral of Tangier Bay (Southwestern Mediterranean Sea).

In the current study, an environmental assessment of surface seawater in Tangier Bay was conducted by analyzing physicochemical parameters and trace elements, such as As, Cr, Zn, Cd, Pb, and Cu. The results showed mean concentrations (μg/l) of 22.50 for As, 0.
