Marine eutrophication, primarily driven by nutrient over input from agricultural runoff, wastewater discharge, and atmospheric deposition, leads to harmful algal blooms (HABs) that pose a severe threat marine ecosystems. This review explores the causes, monitoring methods, control strategies for eutrophication in environments. Monitoring techniques include remote sensing, automated situ sensors, modeling, forecasting, metagenomics. Remote sensing provides large-scale temporal spatial data, while sensors offer real-time, high-resolution monitoring. Modeling forecasting use historical data environmental variables predict blooms, metagenomics insights into microbial community dynamics. Control treatments encompass physical, chemical, biological treatments, as well advanced technologies like nanotechnology, electrocoagulation, ultrasonic treatment. Physical such aeration mixing, are effective but costly energy-intensive. Chemical including phosphorus precipitation, quickly reduce levels may have ecological side effects. Biological biomanipulation bioaugmentation, sustainable require careful management of interactions. Advanced innovative solutions with varying costs sustainability profiles. Comparing these methods highlights trade-offs between efficacy, cost, impact, emphasizing need integrated approaches tailored specific conditions. underscores importance combining mitigate adverse effects on

Rhizosphere is a crucial area in comprehending the interaction between plants and microorganisms constructed wetlands (CWs). However, influence of photoperiod, key factor that regulates photosynthesis rhizosphere microbial activity, remains largely unknown. This study investigated effect photoperiod (9, 12, 15 hours/day) on pollutant removal underlying mechanisms. Results showed 15-hour treatment exhibited highest efficiencies for COD (87.26%), TN (63.32%), NO3--N (97.79%). enhanced photosynthetic pigmentation root which increased transport oxygen soluble organic carbon to rhizosphere, thus promoting nitrification denitrification. Microbial community analysis revealed more stable co-occurrence network due complexity aggregation treatment. Phaselicystis was identified as connector, responsible transferring necessary sources, ATP, electron donors supported optimized nitrogen metabolism CWs. Structural equation model emphasized importance plant-microbe interactions through substance, information, energy exchange. These findings offer valuable insights CWs design operation various latitudes rural areas small-scale decentralized systems.
