Remediation of emerging pollutants using biochar derived from aquatic biomass for sustainable waste and pollution management: a review

Journal of Chemical Technology & Biotechnology, Год журнала: 2023, Номер 99(2), С. 330 - 342

Опубликована: Окт. 30, 2023

Abstract The Coronavirus disease pandemic over the last 3 years has diverted attention of global population from a self‐centred monitory growth to holistic growth, with health and environment as central focus. Pharmaceuticals microplastics have emerged some most prominent environmental contaminants in recent times. Although adsorption is recognized globally low‐cost effective remediation process, removal variety pollutants niches still remains challenge. This review highlights use valorized waste aquatic biomass an adsorbent for withdrawal various emerging (pharmaceuticals, heavy metals). Unwanted invasive plants can be used valuable resource conversion into ideal precursor value product development carbon‐based adsorbents that numerous industrial applications. There lacks comprehensive analysis on biochar, derived biomass, extraction pollutants, especially microplastics. distinctive, timely work will aid expansion research production biochar resource, strengthen their help combat increasing pollution due including pharmaceuticals © 2023 Society Chemical Industry (SCI).

Water hyacinth derived biochar for polycyclic aromatic hydrocarbons removal and oxidative stress study

Environmental Technology & Innovation, Год журнала: 2023, Номер 29, С. 103027 - 103027

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.
