Abstract

Abstract: This research was aimed at evaluating the seasonal partitioning of Zn, Se, As, Cu, and Co in the tissues of Mytilus galloprovincialis sampled at two industrial sites along the Algerian coast. Adult mussels were seasonally collected from two sites over the course of a whole year. The gills, digestive glands, gonads, and remaining soft tissues were analyzed through ICP-MS. The observations led to identifying metals ranges (μg g −1 Dry Weight ) of 67.17–395.51 (Zn), 2.18–12.74 (Se), 7.81–28.61 (As), 3.32–155.91 (Cu), and 0.10–3.59 (Co) in the various tissues. The highest concentrations were found in the digestive glands and gills as compared to the gonads and remaining soft tissues. Distinct patterns of metals partitioning were found: indeed, As and Co concentrations were higher in the digestive glands, while Se and Zn concentrations were higher in the gills. Many of the mussels samples resulted contaminated, therefore potentially posing a considerable health risk to consumers. Highlights: Up to Zn 396, Se 13, As 29, Cu 156, Co 4 ppm were found in mussel tissues. The highest concentrations were found in the digestive gland and gill. As and Co concentrations were higher in the digestive gland. Se and Zn concentrations were higher in the gill. Many of the mussels samples were contaminated beyond the permitted limits.
