Assessing behavior and fate of micropollutants during wastewater treatment: Statistical analysis

Abstract

This study examines the occurrence of micropollutants (n = 46) in raw sewage, as well as the fate of the removal performance for these substances by the Al-Hoceima city wastewater treatment plant. The treatment process removed more than 50-90% of heavy metals from the wastewater. Polycyclic Aromatic Hydrocarbons and Polychlorinated Biphenyls were eliminated from wastewater by 20-50%. The quality of the effluent discharged complied with national and international wastewater discharge standards. Statistical methods were applied to examine the relationships between the concentrations of micropollutants and macropollutants entering and leaving the wastewater treatment plant, and a model for estimating the production of micropollutants, based on a measurement of macro pollution parameters.

Characterization of Leachate and Assessment of the Leachate Pollution Index – A Study of the Controlled Landfill in Fez

“…The efficacy of controlled landfills, provided they are welldesigned, was underscored (Townsend, 2015). As Omor outlined in 2019, these facilities are not merely waste disposal sites; they are strategically engineered to store waste safely (Omor, 2019, El Hammoudani, 2020.…”

Ulva spp (Ulva intestinalis, U. fasciata, U. lactuca, and U. rigida) composition and abiotic environmental factors

“…Ulva spp., such as Ulva intestinalis, Ulva fasciata, Ulva lactuca, and Ulva rigida, are celebrated for their dense concentrations of proteins, lipids, minerals, and vitamins-nutrients crucial for human well-being. Ananthi and Bagyalakshmi (2024), Elmosallamy et al (2021), and Rasyid (2017) have contributed significantly to our understanding of the nutritional potential of Ulva spp., positing these algae as a sustainable food source amidst growing global food security concerns [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32].…”

State of the art of trace metal detection in the mediterranean coastal marine environment, combinatorial approach using mytilus galloprovincialis and surface sediments

“…Their impact on marine ecosystems is profound, affecting biological and ecological processes and potentially leading to bioaccumulation in the food chain, thus posing a direct risk to human health [8][9][10][11]. The Mediterranean coastal marine environment, remarkable for its rich biodiversity and vital importance too many human societies, is today facing increasing challenges due to the presence of trace metals [12]. These metals, from anthropogenic sources such as industry, agriculture and urbanization, as well as natural sources such as soil erosion, accumulate in marine ecosystems [13][14][15].…”
