“…The contaminants originating from human activities are also influenced by the dynamic nature of coastal areas, which are influenced by tides and currents, resulting in low levels of heavy metals (Chai et al, 2019;Akhtar et al, 2021;Chedadi et al, 2023). The Contamination Factor (Cf) of this study shows that each metal causes low contamination, except for Pb, which is included in moderate contamination.…”

Mangrove roots play an important role in reducing heavy metal pollution in their surroundings. This study aimed to assess the bioaccumulation and ecological risk assessment of heavy metal pollution in mangrove roots. Mangrove root samples consisting of two species (Avicennia alba and Excoecaria agallocha) were collected from two observation stations in the mangrove ecosystem of Payung Island, Banyuasin District, South Sumatra, Indonesia. Heavy metal concentrations were measured by atomic absorption spectrometry. Then, statistical analysis was carried out by one-way analysis of variance (ANOVA). Ecological risk assessment used the bioconcentration factor (BCF), geoaccumulation index (I geo ), contamination factor (Cf), and pollution load index (PLI). On the basis of the results, the highest sediment heavy metal concentration at station 2 was Pb amounted to 13.57 ± 0.46 mg/kg, and Cu amounted to 11.08 ± 0.38 mg/kg. In turn, the highest heavy metal concentration of mangrove roots in E. agallocha species for Pb amounted to 2.89 ± 0.033 mg/kg and A. alba for Cu amounted to 10.57 ± 0.38, BCF was classified as exclusion (BCF < 1), except for the BCF of Cu station 1, which was classified as hyperaccumulator (BCF > 1). Igeo shows that the level of pollution is not contaminated (I geo < 0), and Cf shows low pollution (Cf < 1), except Cf Pb station 2 is classified as moderate pollution. Conversely, PLI is included in the category of not polluted (PLI < 0). Mangrove roots play an important role in reducing heavy metal pollution in the surrounding area. Therefore, an in-depth understanding of heavy metal dynamics can be the basis for designing effective coastal environmental conservation strategies.

“…The increase in conductivity downstream was probably due to SO 4 -Mg-Ca enrichment. Sulfates can also come from the dissolution in water of sulfide minerals (Chedadi et al, 2023). This could be the result of the drainage of processing residues and carbonates containing sulfide minerals.…”

The diagnosis of the current state of the environment (groundwater quality and tailings composition) was carried out in the vicinity of the M'fis mine (Southeast of Morocco) in order to evaluate the impact of mine tailings on groundwater. Water samples from the well in the center of the mine site and from other nearby wells were collected and analyzed. In addition, the characterization of the tailings shows the presence of sulfides and other chemical elements, constituting the main source of pollution. In turn, the results of geochemical analyses show that groundwater is characterized by low levels of metals, despite the presence of these pollutants in the tailings and in the waste rock piles. The concentrations of metallic trace elements in well groundwater, slightly exceeding the standards of potability (the WHO standard), remain acceptable for irrigation and for livestock. These results can be explained by the carbonate geological formation, constituting the transfer medium of the pollutants towards the aquifer and also by the weak circulation of the metal ions under the desert climate which prevent dissolution and infiltration.
