Polycyclic aromatic hydrocarbons (PAHs), highly concerned emerging contaminant, are priority persistent organic pollutants (POPs) adversely affect the ecological health of marine sediments. These have attracted widespread attention because their potential toxicological effects on aquatic organisms and subsequent threats to human health. In this study, an advanced oxidation process for remediation PAH-contaminated sediments was developed by activation calcium peroxide (CaO2; CP) using a green catalyst prepared from water hyacinth biochar (WHBC), associated biochar-driven cellular oxidative stress highlighted. The catalytic capacity WHBC determined at pyrolysis temperature between 300 900 °C. 700 °C (WHBC700) CP removed 74% PAHs sediment matrix. Results antioxidant activity evaluation after exposure doses 400–4000 1000–4000 mg L−1 in hepatocarcinoma cell lines (HepG2) 24 h showed enhanced glutathione peroxidase (GPx) catalase (CAT) activities, respectively. Increase mRNA levels superoxide dismutase (SOD) genes also observed (400–4000 L−1), implying that damage caused reactive oxygen species (ROS) inhibited elevating activity. This study attempted demonstrate effective waste-to-resource strategy remediating PAH-polluted addition understanding environmental gene expression carbon-based catalysts HepG2.

Desalination concentrate (DC) is a residue from desalination plants in semiarid regions, and it promising for microalgae cultures. Its effects have been evaluated previsions study involving Spirulina sp. LEB 18 cultures grown medium containing 100% DC, supplemented with 25% Zarrouk nutrients, without reuse. In the present study, was cultivated recycled saline previous experiment over three consecutive cycles using raceways. The DC achieved maximum biomass production of 3.77 g·L−1, surpassing control (3.45 g·L−1), demonstrated high resistance to elevated environmental temperatures, reaching 42.80 °C. Protein levels (≤37%) all essential amino acids (~40% total proteins) fatty relevant impacts on health were reached. Using up cultivation can contribute valorization this add viability regions adequate nutritional composition supplementation humans animals.
