Assessment of Existing Fate and Transport Models for Predicting Antibiotic Degradation and Transport in the Aquatic Environment: A Review

Water, Journal Year: 2023, Volume and Issue: 15(8), P. 1511 - 1511

Published: April 12, 2023

In recent years, the use of antibiotics for human medicine, animal husbandry, agriculture, aquaculture, and product preservation has become a common practice. The application leave significant residues in different forms, with aquatic environment becoming critical sink accumulating antibiotic residues. Numerous studies have been conducted to understand removal persistence environment. Nevertheless, there is still huge knowledge gap on their complex interactions natural environment, mechanism, monitoring fate Water quality models are practical tools simulating transport pollutant mass This paper reports an overview physical, chemical, biological elimination mechanisms responsible degradation surface water systems. It provides in-depth review commonly used quantitative models. An effort made provide compressive modeling philosophy, mathematical nature, environmental applicability, parameter estimation, prediction efficiency, strength, limitation study information linking paradigms kinetics simulation aiming at issues regarding current model development future perspectives help users select appropriate assessment management.

A novel energy-water-carbon coupling system optimization management model based on water environmental carrying capacity under the influence of climate change

Energy Strategy Reviews, Journal Year: 2024, Volume and Issue: 53, P. 101424 - 101424

Published: May 1, 2024

Under climate change, the ability of water bodies to maintain ecology and human activities becomes more fragile, leading shortages. The change in carrying capacity environment further intensifies management difficulties resource-environment-economic system. This study aims establish a comprehensive framework that integrates an interval fuzzy program environmental assessment model obtain optimal state energy-water-carbon coupling system by promoting industrial structure adjustment. It is demonstrated 10 % reduction carbon emissions leads 15 increase Huangshui watershed. influence total energy consumption show downward trend. Water per unit output, emission policies are highly related main control points for policymakers. developed simultaneously considers optimization capacity, assists formulating balanced promote sustainability regional environ-economic

Evaluation of Algal Control Measures in Eutrophic Reservoirs Based on Aquatic Ecosystem Models

Water, Journal Year: 2024, Volume and Issue: 16(11), P. 1494 - 1494

Published: May 24, 2024

The frequency of freshwater cyanobacterial blooms is increasing globally due to climate change and eutrophication, particularly in reservoirs. Reservoir ecosystems exhibit unique characteristics, there a complex relationship between factors such as light, temperature, nutrient salts, hydrology, algal growth. impact the other on growth varies significantly among different Thus, it crucial assess effectiveness various control measures implemented This study conducted comprehensive assessment by establishing eutrophication model for Shanzi Fuzhou City. incorporated meteorology, carbon dynamics, cycling, biological communities. diverse management was systematically evaluated. findings demonstrate that water level, reducing salts sediments, implementing ecological fish stocking effectively suppressed varying degrees improved nitrogen phosphorus levels. Lower levels had significant reproduction, while sediment reduction minimal effect. Conversely, lower did not improve concentrations reservoir, whereas noticeable Consequently, strategies should prioritize external implementation stocking.

Development of an Ecosystem Model Considering Sediment Redox Processes in Enclosed Water Bodies

Water, Journal Year: 2024, Volume and Issue: 16(13), P. 1879 - 1879

Published: June 30, 2024

This study investigates enclosed water bodies to understand the intricate interactions among physical, chemical, and biological processes. A one-dimensional model, integrating sediment ecosystem components, was developed analyze oxygen depletion, nutrient dynamics, influence of organic matter on concentrations due stratification. Oxygen were derived by combining results from a vertical diffusion model with model. The dissolution, adsorption, desorption inorganic substances in bottom mud react differently under anaerobic aerobic conditions, necessitating separate formulations for reduction oxidation reactions In Lake Biwa, Japan’s largest lake, dissolved levels have decreased despite regulatory efforts since 1970s, prompting an investigation into causes oxygen-depleted masses. thus applied examine consumption Biwa’s deep sediments, shedding light anoxia bodies. emphasizes significance sediments quality models their implications ecosystems. Furthermore, adaptive nature this allows its application various bodies, including freshwater reservoirs, lakes, saltwater bays.
