“…POPs are present in the aquatic environment from a wide variety of anthropogenic sources such as industrial, agricultural, and municipal effluents, atmospheric deposition, coastal activities, shipping, and accidental spills [4][5][6]. OCPs have been banned by the Stockholm Convention since 2001 and are listed as primary pollutant concerns [7][8].…”

The main objective of this initial study is to assess the extent of surface water contamination in Marchica Lagoon caused by organochlorine pesticides (OCPs) historically used in agriculture through a sampling network consisting of eight stations covering all areas of the lagoon during the 2022 summer season. Located on Morocco’s Mediterranean coast, the lagoon has undergone several restoration actions since 2010 to improve its environmental state. However, this ecosystem is under constant pressure from its watershed, which can convey water pollution from agricultural, industrial, mining, and domestic sources, making continuous monitoring essential. Eight organochlorine pesticides (Alpha HCH, Beta HCH, Gamma HCH, Aldrin, Dieldrin, DDD, DDE, and DDT) were detected by gas chromatography-mass spectrometry (GC-MS) using the SIM (Selected Ion Monitoring) method. The results revealed OCPs contamination of the lagoon’s surface waters; the spatial variation of total OCPs concentrations (Σ8OCPs) ranged from 7.58 to 18.79 ng/l. The predominant element detected was β-HCH (lindane), recorded between the Bouarg channel and Selouane wadi, an area characterized by intensive agriculture.

Oued Nfifikh is a coastal stream of the Bouregreg and Chaouia watershed (Morocco). It passes through many rural and urban areas and receives different types of liquid and solid discharges from anthropogenic activities adopted along the watercourse. This study aims to evaluate the physicochemical quality of the water from the most accessible sites upstream and downstream of Oued Nfifikh, along with highlighting the impact of human activities on these waters' quality. For this purpose, water samples were collected and analyzed within normalized methods. Statistical analysis of the collected data shows significant spatial variations (p value < 0.05) for pH, electrical conductivity, nitrate and chloride, and for metallic trace elements (Zn, Fe, Ba, Mn, Cr and Al). Unlike (temperature, Pb, Ni, Cu and Cd), whose values do not present statistically significant variations (p value > 0.05). The study of the physicochemical quality reveals that the waters at the upstream are classed as good quality, except for site (S2), located at the upstream part of the river, it is affected by human activities. Consequently, its physicochemical composition is quite similar to that of waters of poor quality at the downstream sites. The Principal Component Analysis of the results followed by the Ascending Hierarchical Classification on the same data matrix allowed to regroup the sampling sites with similar characteristics into three distinct groups. A group of highly mineralized waters, a second group dominated by elements indicating urban pollution, and a group of waters with low mineral content and low metallic contamination indicating agricultural pollution.

Physical-Chemical Characterization and Heavy Metals Assessment of Waters and Sediments of Sebou Watershed (Top Sebou, Morocco)

Abstract: The main purpose of this study was to investigate the impact of human activities, geochemical background and seasons on pollutant pathway. Surface water, groundwater and sediments were assessed to highlight and confirm those impacts. Sixteen physico-chemical parameters were measured (T°,
