Abstract
The rapid expansion of agriculture in the Souss Massa region has been accompanied by a significant increase in pesticide usage to protect and increase crop yields. Unfortunately, these pesticides leave behind residues that can have detrimental effects on both human health and the environment. To investigate the impact of pesticide contamination on the coasts of Agadir Bay, our study focuses on the bivalve Perna perna (Linnaeus, 1758) as a biomonitoring sentinel species. Between autumn 2009 and summer 2010, we conducted measurements of pesticide residue concentrations and assessed two biomarkers of pollution the Glutathion-S-transferase (GST) and acetylcholinesterase (AChE) in the soft tissues of P. perna. These bivalves were seasonally collected from two different locations along the Agadir Bay coast. The results revealed that Glutathion-S-transferase and acetylcholinesterase showed seasonal variations, likely influenced by the species' reproductive cycle. In terms of pesticide concentrations, the levels of organochlorines were found to range from 13.40 to 109.76 ng g−1 of dry weight (dw) for Dichlofluanide, not-detected (ND) to 38.66 ng g−1 dw for Endosulfan S, ND to 15.76 ng g−1 dw for Lindane, ND to 33.66 ng g−1 dw for Fenarimol, and 0.26–35.02 ng g−1 dw for Buperimate. It should be noted that these levels of pesticide contamination are relatively low compared to values reported in similar studies conducted in other regions of the world. The contamination of Agadir Bay by pesticides can be attributed to their extensive use in agricultural practices in the Souss Massa region.
期刊介绍:
Tropical Ecology is devoted to all aspects of fundamental and applied ecological research in tropical and sub-tropical ecosystems. Nevertheless, the cutting-edge research in new ecological concepts, methodology and reviews on contemporary themes, not necessarily confined to tropics and sub-tropics, may also be considered for publication at the discretion of the Editor-in-Chief. Areas of current interest include: Biological diversity and its management; Conservation and restoration ecology; Human ecology; Ecological economics; Ecosystem structure and functioning; Ecosystem services; Ecosystem sustainability; Stress and disturbance ecology; Ecology of global change; Ecological modeling; Evolutionary ecology; Quantitative ecology; and Social ecology.
The Journal Tropical Ecology features a distinguished editorial board, working on various ecological aspects of tropical and sub-tropical systems from diverse continents.
Tropical Ecology publishes:
· Original research papers
· Short communications
· Reviews and Mini-reviews on topical themes
· Scientific correspondence
· Book Reviews
