Microplastics are pollutants formed from fragmented plastics and also industrially manufactured for personal care cosmetic products. They range 1 µm to 5 mm ubiquitous in the environment due their tiny size, lightweight, wide applications. Ecotoxicological studies have shown that they can induce multiple harmful effects on exposed organisms humans. Wastewater treatment plants (WWTPs) drawn interest of researchers regulatory bodies worldwide as a point source microplastics discharge environment. In absence standardized methodology, microplastic monitoring WWTPs has been marked by distinct variations sample processing analytical procedures which limit comparison results. This review provides detailed analysis methods patterns, analytical, size characterization, quantification WWTPs. According procedural steps extraction reported reviewed studies, 12 patterns three categories approaches (single, dual, multiple) were identified. quantified using gravimetry method, mass sub-sample method (based extrapolation) with latter being most applied technique. Microplastic characterization accomplished two main methods: sieve-based technique computing-based

Understanding the Water Quality Changes of the Typical Plain River Network Area Using Comprehensive Assessment Methods

Sustainability, Journal Year: 2024, Volume and Issue: 16(20), P. 8766 - 8766

Published: Oct. 10, 2024

Water quality assessment is an important method for understanding the spatial-temporal variation characteristics of water quality. Therefore, present study has been performed to evaluate a typical plain river network area in Changzhou City, Jiangsu, China, where system characterized by reciprocal flow and diverse pollution sources. The samples from 2017 2021 were comprehensively assessed using comprehensive methods that combine single-factor index (SFPI) with multivariate statistical analysis. Initially, analyses conducted exceedances correlations SFPI was applied classify categories. Furthermore, principal component analysis (PCA) cluster (CA) employed reduce dimensionality indicators group monitoring sections similar characteristics. results indicate overall City lightly polluted trend improvement. primary pollutants identified are total phosphorus (TP) ammonia nitrogen (NH3-N). This highlights organic pollution, self-purification capacity, eutrophication bodies most significant factors affecting sampling sites classified into three groups (good, moderate, poor). this provide theoretical reference environment management ecological protection areas.

Pollution Characteristics and Eutrophication Assessment in Plain River Network Areas: A Case Study of the Beijing–Hangzhou Grand Canal (Changzhou Section)

Water, Journal Year: 2024, Volume and Issue: 16(23), P. 3353 - 3353

A comprehensive understanding of water-quality spatiotemporal variations is essential for the long-term management aquatic environments. However, absence indicators that fully capture extent eutrophication, lack monitoring data, and complexity water pollutants sources have limited research on pollution characteristics eutrophication assessments in plain river network areas. In this study, based data Beijing–Hangzhou Grand Canal (Changzhou section), temporal spatial distribution nutrient salts, as well status body, were revealed by using trophic level index (TLI) method. Meanwhile, main defined, targeted control measures proposed. The results showed deterioration more pronounced during non-flood season, with significantly higher concentrations ammonia nitrogen (NH3-N) total phosphorus (TP) compared to flood season. Additionally, analysis nitrogen-to-phosphorus (N:P) ratio suggested some sampling sites exhibited limitation. assessment indicated most sections are eutrophic, S8 S2 being heavily polluted at risk cyanobacterial blooms. primary identified agricultural runoff, domestic sewage, industrial discharges. To address these issues, it was recommended reduce external while focusing internal (1. Enhance livestock poultry farming; 2. Upgrade wastewater purification facilities; 3. Establish ecological protection zones along riverbanks) enhance ecosystem restoration. coordinated watershed-wide approach crucial improving quality region. findings study provide a scientific basis environment

The Ecological Effect of Ship Canals on Wetlands

Water, Journal Year: 2024, Volume and Issue: 16(22), P. 3324 - 3324

Published: Nov. 19, 2024

Ship canals, which play a crucial role in facilitating transport, exert significant and long-term impacts on wetland ecosystems. For social economic development, numerous countries have put forward plans for ship canals. This paper reviews the literature ecological effect of canals ecosystems, identifies research gaps, suggests future directions. typically involve high construction intensity, usually including river regulation, locks, water diversion navigation. The effects wetlands refer to changing hydrological processes, degrading quality, eliminating botany, disturbing animals, increasing threats. cumulative impact can either alter trend succession or degrade biodiversity. Thus, there is need further elucidate mechanisms by affect enhance practices protection associated with develop robust evaluation system green canal projects.

Abstract Major cities are particularly affected by the escalating issue of municipal solid waste (MSW) pollution. Among various forms waste, plastic is especially concerning due to its persistence and tendency fragment into microplastics. This study focuses on Jangli River located in Semarang City, Indonesia, quantify characterize riverine microplastic pollution assess impact nearby a MSW Temporary Processing Site (TPS). Through water sampling, field observations, laboratory analysis, we identified classified microplastics color type, determining their abundance across different river points. Our findings reveal correlation between proximity processing site increased levels. Specific hotspots along were after location TPS, highlighting areas with highest contamination. research underscores urgent need for targeted interventions manage mitigate secondary pollution, specifically Indonesia’s waterways, advocating effective environmental control measures protect aquatic ecosystems.
