In recent years, the diverse industrial practices and human inputs widely disseminated emerging contaminants (ECs) throughout environmental matrices, which is of great concern. Even at low concentrations, ECs pose major ecological problems and threaten human health and the environment’s biota. Consequently, people’s interest and concerns on the widespread dissemination of environmentally connected ECs of great concern as developed due to their scientific understanding, technical innovation, and socioeconomic awareness. Increased detection of contaminants may occur from climatic, socioeconomic, and demographic changes and the growing sensitivity of analytical techniques. Hence, this article reviews the determination of ECs in ecological specimens, from aquatic setup (river water, marine water, and wastewater), sludge, soil, sediment, and air. Sample collection and the quality measures are summarized. The preparation of samples, including extraction and cleanup and the subsequent instrumental analysis of ECs, are all covered. Traditional and recent extraction and cleanup applications to analyze ECs in samples are reviewed here in this paper. The detection and quantification of ECs using gas chromatography (GC) and liquid chromatography (LC) linked with various detectors, particularly mass spectrometry (MS), is also summarized and explored, as are other possible techniques. This study aims to give readers a more excellent knowledge of how new and improved approaches are being developed and serve as a resource for researchers looking for the best method for detecting ECs in their studies.

Biopolymers have received a lot of interest recently, and academic and industrial research on biopolymers has been refocused. These biopolymers comprise naturally occurring substances as well as artificial substances created from naturally occurring monomers. Plastics have the potential to be replaced by biopolymers because they are hazardous to the environment and rely on nonrenewable resources like petroleum for production. Due to the overwhelming interest in biopolymers, characterization tools and processes have emerged as crucial components in biopolymer research to examine and enhance the characteristics and functionality of materials based on biopolymers. When evaluating the performance of these bio-nanocomposites, using the right tools for characterization is crucial. This review concentrated on high-level analytical methods for characterizing biopolymers, biopolymer-based composites, and their derivatives structurally, physically, and chemically. The most common analytical instrument methods based on microscopy (Optical, laser scanning confocal, scanning tunneling, scanning probe, differential dynamic, scanning, and transmission electron) and spectroscopy (Fourier transform infrared, X-ray diffraction, and Raman). The use of these tools for characterization in current research studies is also highlighted in order to demonstrate how the biopolymer under study might be used in various applications.
