The aim of this a pioneering research is to investigate linear alkylbenzenes (LABs) as biomarkers of sewage pollution in sediments collected from four rivers and estuaries of the south and east of Peninsular Malaysia. The sediment samples went through soxhlet extraction, two-step column chromatography purification, fractionation and gas chromatography-mass spectrometry (GC-MS) analysis. Principal component analysis (PCA) with multivariate linear regression (MLR) was used as well for source apportionment of LABs. The results of this study showed that total LAB concentration was 36-1196 ng gdw. The internal to external isomer ratios (I/E ratio) of LABs were from 0.56 to 3.12 indicated release of raw sewage and primary and secondary effluents into the environment of south and east of Peninsular Malaysia. Our research supported that continuous monitoring of sewage pollution to limit the environmental pollution in riverine and estuarine ecosystem.

Estuarine mangroves are crucial for trapping microplastics and contributing to coastal protection; however, their effectiveness during extreme weather events remains unclear. This study investigated the effects of typhoons on microplastic dynamics within the watershed-estuary-offshore system and the changes in the role of estuarine mangroves. Surface water from the Shenzhen River and sediments from estuarine mangroves were sampled after typhoons (Saola and Haikui) and during periods of stable hydrodynamic conditions.

Sand mining is ubiquitous given the universal demand for aggregate materials for construction and other manufacturing industries. This demand is mostly met by mining fluvially derived sediment from rivers and estuaries, resulting in extensive, enduring changes to the morphological, physico-chemical and biological characteristics of aquatic ecosystems. The extent of these activities in South Africa is largely unknown due to the dynamic, ephemeral, and often clandestine operations, which are mainly located in remote or inaccessible areas.

Microplastics (MPs) pollution has emerged as a global concern. To mitigate the potential threats by MPs, particularly to coastal regions, it is crucial to comprehend the environmental behavior of MPs and their affiliated chemicals. In the present study, we collected floating MPs using a Manta net (0.

Researchers and environmental managers need big datasets spanning long time periods to accurately assess current and historical water quality conditions in fresh and estuarine waters. Using remote sensing data, we can survey many water bodies simultaneously and evaluate water quality conditions with greater frequency. The combination of existing and historical water quality data with remote sensing imagery into a unified database allows researchers to improve remote sensing algorithms and improves understanding of mechanisms causing blooms.

Article Synopsis
- - This study examined microplastics (MPs) and their associated microbial communities in the Sarno River, its estuary, and coastal area during January 2020 using advanced scientific techniques.
- - Significant differences were found in MP concentrations and microbial compositions across the three locations, with the estuary having particularly high levels of MPs, indicating a potential threat to coastal ecosystems.
- - The research identified that the Comamonadaceae family dominated in freshwater and MP-attached communities, emphasizing the role of microplastics in facilitating the spread of certain microbes as they travel from river to sea, underscoring the need for effective management strategies.
