Chlorinated organic pollutants constitute a significant category of persistent due to their widespread presence in the environment, which is primarily attributed expansion agricultural and industrial activities. These are characterized by persistence, potent toxicity, capability for long-range dispersion, emphasizing importance eradication mitigate environmental pollution. While conventional methods removing chlorinated encompass advanced oxidation, catalytic bioremediation, utilization biochar has emerged as prominent green efficacious method recent years. Here we review biochar's role remediating typical organics, including polychlorinated biphenyls (PCBs), triclosan (TCS), trichloroethene (TCE), tetrachloroethylene (PCE), organochlorine pesticides (OCPs), chlorobenzenes (CBs). We focus on impact material properties adsorption mechanisms organics. This highlights use sustainable eco-friendly pollutants, especially when combined with biological or chemical strategies. Biochar facilitates electron transfer efficiency between microorganisms, promoting growth dechlorinating bacteria mitigating toxicity organics through adsorption. Furthermore, can activate processes such oxidation nano zero-valent iron, generating free radicals decompose compounds. observe broader application bioprocesses treating soil, reducing impacts. Conversely, water-based integrating proved more effective, leading superior purification results. contributes theoretical practical pollutants.

It is urgent to find alternatives fossil fuels mitigate the effects of climate change. High light intensity during microalgal growth can promote lipid and carbohydrate accumulation (feedstocks biofuels). However, more research needs be done concerning effect this factor on productivity biochemical composition from a phase point view. This study evaluated impact high intensities (291, 527 1107 μmol m−2 s−1) Chlorella vulgaris in synthetic wastewater, nutrient assimilation late-exponential stationary phases. Under highest intensity, higher rate (0.54 ± 0.02 d−1) maximum (166 13 mg/L were achieved. Also, removal efficiencies at reached 97.0 0.2 % 98.2 0.1 for nitrogen phosphorus, respectively. all tested phase, microalgae also achieved (>95 %).
