Water Sampling

Polycyclic aromatic hydrocarbons (PAHs) in water pose a serious threat to human health due to their toxic effects. This manuscript evaluates various drinking water treatment processes to remove these compounds from drinking water, in order to assure the quality of water intended for human consumption.
Microplastics are emerging pollutants in aquatic and terrestrial environments. In the last years, several case studies and reviews have been published about microplastics in freshwater and marine environments. However, no standardized methods are available for sampling and sample preparation. Based on literature research, this review presents different techniques and methods for sampling as well as the preparation of microplastic samples from water, sediment and biota of freshwater and marine environments.

Microplastics are widespread contaminants, virtually present in all environmental compartments. However, knowledge on sources, fate and environmental concentration over time and space still is limited due to the laborious and varied analytical procedures currently used. In this work we critically review the methods currently used for sampling and detection of microplastics, identifying flaws in study design and suggesting promising alternatives.

This review provides insight into the abundance, origin, distribution and composition of MPs in the sea surface and water column of the Mediterranean Sea. Literature data on MP particles on the sea surface showed an evident heterogeneous distribution and composition, with marked geographical differences between Mediterranean sub-basins. A standardized protocol for water sampling, extraction and detection of plastic debris is strongly recommended.
Microplastics pollution in aquatic ecosystems has aroused increasing global concern, leading to an explosive growth of studies regarding microplastics published in the past few years. To date, there is still a lack of standardized methodologies used for the detection of microplastics within environmental samples, thus hampering comparison of the reported data.
As emerging contaminants, antibiotic resistance genes (ARGs) have become a public concern. This study aimed to investigate the occurrence and diversity of ARGs, and variation in the composition of bacterial communities in source water, drinking water treatment plants, and tap water in the Pearl River Delta region, South China. Various ARGs were present in the different types of water. Among the 27 target ARGs, floR and sul1 dominated in source water from three large rivers in the region.
