“…Although drugs have many benefits and restore human health, improper disposal of expired and unused drugs causes them to enter waterways, pollute the environment, and affect the growth of aquatic plants and bacteria [ 108 ]. The excretion of unmetabolized drugs and narcotics from the body is another source of contamination of wastewater with pharmaceutical pollutants [ 13 ]. Also, the entry of pharmaceuticals into the drinking water supply, coupled with frequent exposure to these substances, can enhance the body’s resistance to drug effects during the progression of illness [ 109 ].…”

“…Also, due to their combination with chlorine, drugs can cause serious diseases such as respiratory diseases and mucous membrane irritation. In recent years, with the increase in the use of drugs due to the coronavirus disease, the amount of pharmaceutical pollutants in wastewater has grown significantly, and the issue of removing these pollutants has become more important than before [ 13 ]. Among the porous biopolymers that can be used to remove pollutants such as drugs is starch, which is the second most abundant biopolymer on the surface of the Earth.…”

“…Environmental concerns regarding water treatment are not only limited to the removal of pollutants, but a sustainable environment through sustainable consumption is also important [ 13 ]. As a result, the use of approved methods and materials in circular engineering can reduce these concerns [ 14 , 15 , 16 ].…”

The increasing awareness of the importance of a clean and sustainable environment, coupled with the rapid growth of both population and technology, has instilled in people a strong inclination to address the issue of wastewater treatment. This global concern has prompted individuals to prioritize the proper management and purification of wastewater. Organic pollutants are very persistent and due to their destructive effects, it is necessary to remove them from wastewater. In the last decade, porous organic polymers (POPs) have garnered interest among researchers due to their effectiveness in removing various types of pollutants. Porous biopolymers seem to be suitable candidates among POPs. Sustainable consumption and environmental protection, as well as reducing the consumption of toxic chemicals, are the advantages of using biopolymers in the preparation of effective composites to remove pollutants. Composites containing porous biopolymers, like other POPs, can remove various pollutants through absorption, membrane filtration, or oxidative and photocatalytic effects. Although composites based on porous biopolymers shown relatively good performance in removing pollutants, their insufficient strength limits their performance. On the other hand, in comparison with other POPs, including covalent organic frameworks, they have weaker performance. Therefore, porous organic biopolymers are generally used in composites with other compounds. Therefore, it seems necessary to research the performance of these composites and investigate the reasons for using composite components. This review exhaustively investigates the recent progress in the use of composites containing porous biopolymers in the removal of organic pollutants in the form of adsorbents, membranes, catalysts, etc. Information regarding the mechanism, composite functionality, and the reasons for using each component in the construction of composites are discussed. The following provides a vision of future opportunities for the preparation of porous composites from biopolymers.

“…Currently, the concentration level of several micropollutants is regulated; nevertheless, they are a minimal part of the possible substances of health concern that can be present in the effluents among the following categories: pharmaceuticals and their metabolites, personal care products, pesticides, flame retardants, plasticizers, oxidation treatment by-products, etc. [ 1 , 2 ]. A non-target analysis approach can be used to identify unknown substances and isolate multipollutant signatures related to specific sources using HPLC-HRMS methods [ 3 , 4 , 5 ].…”

(1) Background: Monitoring effluent in water treatment plants has a key role in identifying potential pollutants that might be released into the environment. A non-target analysis approach can be used for identifying unknown substances and source-specific multipollutant signatures. (2) Methods: Urban and industrial wastewater effluent were analyzed by HPLC-HRMS for non-target analysis. The anomalous infiltration of industrial wastewater into urban wastewater was investigated by analyzing the mass spectra data of “unknown common” compounds using principal component analysis (PCA) and the Self-Organizing Map (SOM) AI tool. The outcomes of the models were compared. (3) Results: The outlier detection was more straightforward in the SOM model than in the PCA one. The differences among the samples could not be completely perceived in the PCA model. Moreover, since PCA involves the calculation of new variables based on the original experimental ones, it is not possible to reconstruct a chromatogram that displays the recurring patterns in the urban WTP samples. This can be achieved using the SOM outcomes. (4) Conclusions: When comparing a large number of samples, the SOM AI tool is highly efficient in terms of calculation, visualization, and identifying outliers. Interpreting PCA visualization and outlier detection becomes challenging when dealing with a large sample size.
