This research investigates the effects of environmental interventions on pollution levels along the Anza coast of Morocco from 2010 to 2022 through the analysis of biomarkers in Perna perna. Historically, the Anza area has been highly polluted compared to the nearby Cap Ghir coast. Following the relocation of a cement factory and the establishment of wastewater treatment facilities, notable environmental improvements were noted in Anza. Pollution biomarkers such as acetylcholinesterase (AChE), catalase, glutathione S-transferases (GSTs), and malondialdehyde (MDA) were analyzed to assess these changes. The findings indicated an increase in catalase and AChE levels at Anza, suggesting reduced contamination, while GST activity declined, indicating lower exposure to pollutants. In contrast, Cap Ghir showed an increase in oxidative stress biomarkers, suggesting worsening environmental conditions. The Integrated Biomarker Response (IBR) index demonstrated a significant reduction in pollution levels in Anza, with a corresponding increase at Cap Ghir. Principal Component Analysis (PCA) supported these outcomes, revealing a positive correlation between catalase activity and reduced oxidative stress at Anza, whereas Cap Ghir showed elevated oxidative stress markers linked to variations in temperature and salinity. These results underscore the effectiveness of the interventions in enhancing marine health at Anza and highlight the necessity for protective actions at Cap Ghir. This study emphasizes the importance of biomonitoring in shaping environmental policies for coastal areas of Agadir city.

Article Synopsis
  • A multibiomarker approach assesses the impact of environmental stressors on ecosystems and human health, specifically in the central Atlantic Ocean of Morocco affected by various pollutants.
  • The study measured four biomarkers in the mussel Mytilus galloprovincialis from four different sites, each facing unique industrial, agricultural, and touristic impacts.
  • Results indicated seasonal variability in biomarker responses, with significant findings such as AChE inhibition and GST induction being highest at specific sites, emphasizing the need for this approach in environmental monitoring and resource protection.

In Agadir Bay, a study evaluated pollution biomarkers in the mollusk species Patella vulgata. Samples were collected seasonally from September 2021 to September 2022 at two distinct coastal sites within Agadir Bay: Cap Ghir and Anza Beach. Notable variations were observed in biomarkers like malondialdehyde, with a peak at 10.

Laboratory of Aquatic Systems: Marine and Continental Ecosystems, Department of Biology, Faculty of Sciences, Ibn Zohr University, BP 8106, Agadir, Morocco.

The present study aims to evaluate the initial health status of two stations receiving seawater desalination plants in Agadir Bay ( and ) and to assess their potential environmental impact on the marine ecosystem health. Six pairs of mussels () were collected at six sampling sites on a monthly basis over two years. Each pair was homogenized to obtain the postmitochondrial fractions (S9).

This study reports the occurrence of different Vibrio and Salmonella species in 52 samples of Mytilus galloprovincialis collected from four sites along the Atlantic coast between Agadir and Essaouira (Anza, Cap Ghir, Imssouane and Essaouira). The level of Escherichia coli (E. coli) was also determined to evaluate the degree of microbial pollution in the investigated areas.
