“…Heavy metals may build up to hazardous amounts under some environmental circumstances, which might harm the ecosystem [6]. Given their vital functions in biological systems, iron, zinc, copper, and manganese are considered essential metals; nevertheless, in larger amounts, they become hazardous [7][8][9][10]. When non-essential metals like Pb and Cd bioaccumulate in tissues, they can cause intoxication, cellular and tissue damage, diminished fertility, malfunction of several organs, and even cell death.…”

Trace metals (Li, B, Na, Mg, Al, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Se, Sr, Ag, Cd, In, Ba, Hg, Pb, Bi) in surface sediments of the Nile Delta coastal area between Western Harbor and Bardaweel Lagoon were evaluated. The ecological risk assessment was evaluated by Contamination degree (Cd), Geoaccumulation Factor (Igeo), Enrichment Factor (EF), Contamination Factor (CF), Hazard Quotient (HQ) and Pollution Load Index (PLI). The EF values are in the sequence: Cr > Pb > Ni > Zn > Cu > Mn. The studied locations were unpolluted with Cr, Cu, Mn, Ni, Pb, and Zn (Igeo ≤0) and the Cd (> 1.5). Significant correlations were reported between the concentrations of Mn, Fe, Cr, Co and Ni suggesting similar sources. The HQ indicate low values for children and 3–4 > adult values. Using principal component analysis (PCA), the sources of heavy metals were categorized.

Chlorella vulgaris is an inexpensive microalga that could be employed for environmental remediation, but further investigations are needed to assess its suitability and optimal treatment methodology. With this aim in mind, this study focused on the raw biomass and the biochar and hydrochar obtained from it, analyzing their physicochemical properties and testing them to capture cadmium from an aqueous environment. The adsorption/absorption tests assessed the effect of adsorbent dosage, pH, Cd concentration, and contact time, and the results were analyzed through a structural equation model. Biochar and hydrochar performed similarly and better than the raw biomass, with the highest Cd removal observed at an adsorbent dosage of 0.8 g L−1, an initial concentration of Cd solution of 30 mg L−1, a pH of 6, and a contact time of 30 min. The adsorption isotherm data for Cd could be well-described by the Langmuir and Temkin models. The results from the structural equation modeling revealed that the variables material type, dosage, and concentration all contributed to Cd removal in water, with time mediating these effects.
