Article Synopsis
- The study examined the contamination of Betoya Bay's surface sediments by potentially toxic elements (PTEs) to determine pollution levels and sources.
- The results showed that while PTE levels were generally low, specific sites near intense fishing and runoff showed higher concentrations, indicating localized pollution.
- Health risk assessments revealed that beach sand is safe for adults and children, but children face a moderate to high risk of cancer from PTE exposure.
This study examines the concentrations of arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), mercury (Hg) and zinc (Zn) in three fish species (Sardina pilchardus, Engraulis encrasicolus, Trachurus trachurus) from Betoya Bay, collected in winter and summer. Significant variations were observed between tissues (p < 0.05), with the liver being the most contaminated.

Concentrations of toxic metals (Hg, Pb, and Cd) were determined in the muscles of , , and caught from the Moulouya River of Morocco by graphite furnace (for Pb and Cd) and cold vapour (for Hg) atomic absorption spectrometry, after acid digestion. Although the concentration of metals in some species was relatively high, no health risk has been identified in comparison to the maximum limits as set by the European Commission. The order of increasing concentrations was Cd < Hg < Pb.
