“…Concentrations of 4NP in coastal sediments are of greater concern. While the bioavailability of 4NP to pelagic organisms decreases with partitioning to particulates, benthic organisms are still affected (Madrid et al, 2020). Oligochaetes and insects in benthic communities have demonstrated bioaccumulation and show sublethal effects of 4NP (Mäenpää & Kukkonen, 2006).…”

“…Sorption-desorption phenomena determine the fate of organic micropollutants in WWTPs. Moreover, the interaction of organic pollutants with activated sludge in uences their bioavailability to microorganisms and the subsequent biodegradation during biological treatment (Madrid et al 2020). The lack of data on SS contamination by organic pollutants, possibly due to the complexity of the matrix, and the potential negative effects on the environment, such as the possibility of migration from soils to crops, are…”

This study presents a thorough evaluation of emerging and priority micropollutants in sewage sludge (SS), through the lens of environmental insights, by developing and implementing an integrated analytical approach. A quick, easy, cheap, effective, rugged and safe (QuEChERS) extraction method, coupled with gas chromatography and liquid chromatography, was optimized for the determination of 42 organic compounds. These include organophosphorus pesticides, organochlorine pesticides, pyrethroid pesticides, organophosphate ester flame retardants, polybrominated diphenyl ethers, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons. The optimization of the dispersive-solid phase for clean-up, combined with the optimization of chromatographic parameters, ensured improved sensitivity. Method validation included assessments for recovery, reproducibility, limit of detection (LOD), and limit of quantification (LOQ) assessments. Recoveries ranged from 59.5–117%, while LODs ranged from 0.00700 µg g− 1 to 0.271 µg g− 1. Application of the method to seven SS samples from Portuguese wastewater treatment plants revealed the presence of sixteen compounds, including persistent organic pollutants. Notably, the quantification of α-endosulfan, an organochlorine pesticide, was consistently observed in all samples, with concentrations ranging from 0.110 µg g− 1 to 0.571 µg g− 1. Furthermore, the study encompasses the analysis of agronomic parameters, as well as the mineral and metal content in SS samples. The study demonstrates that the levels of heavy metals comply with legal limits. By conducting a comprehensive investigation into the presence of micropollutants in SS, this study contributes to a deeper understanding of the environmental and sustainable implications associated with SS management.

“…Due to its high protein content and global mass production (approximately 11 million Mg of d.m. in the EU (Madrid et al 2020)), sewage sludge can be a source of plant biostimulators (including peptides or free amino acids). The increased bioavailability of these compounds can only be achieved by composting or hydrolysis (Xu and Geelen 2018).…”

This literature review outlines the most important—agricultural and non-agricultural—types of sewage sludge management. The potential of waste sludge protein hydrolysates obtained by chemical sludge conditioning was reported. The discussed areas include acidic and alkaline hydrolysis, lime conditioning, polyelectrolyte dewatering and other supporting techniques such as ultrasounds, microwave or thermal methods. The legislative aspects related to the indication of the development method and admission to various applications based on specified criteria were discussed. Particular attention was devoted to the legally regulated content of toxic elements: cadmium, lead, nickel, mercury, chromium and microelements that may be toxic: copper and zinc. Various methods of extracting valuable proteins from sewage sludge have been proposed: chemical, physical and enzymatic. While developing the process concept, you need to consider extraction efficiency (time, temperature, humidity, pH), drainage efficiency of post-extraction residues and directions of their management. The final process optimization is crucial. Despite the development of assumptions for various technologies, excess sewage sludge remains a big problem for sewage treatment plants. The high costs of enzymatic hydrolysis, thermal hydrolysis and ultrasonic methods and the need for a neutralizing agent in acid solubilization limit the rapid implementation of these processes in industrial practice.
