Heavy metals originating from industrial runoff, agricultural practices, urbanization, and natural geological processes persist in coastal sediments due to their low degradation rates high stability. Their cycling is influenced by sediment dynamics, water circulation, complex interactions with biological chemical factors. metal pollution demonstrates serious risks biota, including fish, shellfish, algae, marine mammals through mechanisms such as bioaccumulation biomagnification. These lead biodiversity loss, habitat degradation, reduced ecosystem functionality. Current mitigation strategies for control regulations remediation techniques show promise but face challenges implementation. Emerging technologies nanotechnology bioremediation offer innovative solutions require further validation. Knowledge gaps understanding the long-term ecological impacts of heavy contamination optimizing management diverse ecosystems. Coastal ecosystems are vital supporting providing essential services, they increasingly threatened pollution—a pervasive environmental challenge that demands urgent attention. This review investigates sources, characteristics, pathways, impacts, associated environments. The synthesizes findings recent literature, employing a systematic approach analyze anthropogenic biogeochemical governing cycling. Future research should focus on addressing these interdisciplinary approaches, integrating advanced modeling techniques, stakeholder engagement, sustainable practices. By prioritizing efforts, we can safeguard services escalating threats pollution.

Mitigating cadmium contamination in soil using Biochar, sulfur-modified Biochar, and other organic amendments

International Journal of Phytoremediation, Год журнала: 2025, Номер unknown, С. 1 - 14

Biochar is a novel approach to remediating heavy metal-contaminated soil. Using various organic amendments like phyllosilicate-minerals (PSM), compost, biochar (BC) and sulfur-modified (SMB), demonstrates superior adsorption capacity stability compared unmodified (BC). The mechanisms of SMB are identified for its potential increase soil-pH reduce available cadmium (Cd). study reveals the BC in immobilizing Cd contaminated demonstrated highest Cd, followed by BC, PSM, with capacities ranging from 7.47 17.67 mg g-1. Both exhibit high (12.82 g-1, respectively) low desorption percentages (4.46-6.23%) at ion strengths 0.01 0.1 mol-L-1 pH levels 5 7. showed higher (17.67 g-1) lower percentage BC. mechanism involves surface-precipitation, exchange, formation Cd(OH)2 CdCO3 precipitates, as well interactions between sulfur, leading more stable-Cd CdHS+ compounds. Adding 1% increased soil significantly reduced demonstrating pollutant remediation. underscores promise providing sustainable solution Cd-contaminated

Bioremediation of Sulfamethazine Contaminated Environments by Bacillus cereus J2

Water, Год журнала: 2025, Номер 17(4), С. 468 - 468

Опубликована: Фев. 7, 2025

Sulfamethazine (SM2), a prevalent sulfonamide antibiotic, is commonly detected as an environmental pollutant. Microbial degradation serves important approach to treating SM2 contamination. In this study, SM2-degrading strain, identified Bacillus cereus J2, was isolated from the activated sludge that had been cultured using exclusive carbon source, which demonstrated exceptional capabilities. Under optimized conditions (30 °C, initial OD600 = 0.1, pH 8), strain J2 completely degraded 50 mg/L within 36 h. The also showed high efficiency for other sulfonamides, such sulfamethoxazole and sulfadiazine, could grow normally in mixed system containing these compounds. growth kinetics with source conformed well Haldane model (R2 0.925), revealing strain’s maximum specific rate determined be 0.066 h−1 (µmax) at concentration of 51.35 mg/L. Seven intermediate products were TQ-LCMS analysis, suggesting three potential pathways SM2. These findings suggest holds significant promise bioremediation SM2-contaminated environments.
