“…PAHs have been described as carcinogenic compounds difficult to degrade and accumulating in food chains (Whyte et al, 2000). PCBs are organic chlorine compounds that can be absorbed by the soil through organic matter and accumulate in the food chains (Valizadeh et al, 2021).…”

The main objective of this thesis was to evaluate metabolomics changes in humans and fish as a response to food/feed consumption. To alleviate the environmental impact of animal production and maximize the use of resources, the valorization of meat by-products might be an attractive alternative. A meat product containing heart and aorta tissue from pork was designed and analyzed for fatty acid and metabolite composition. In comparison with a control of similar qualities, the designed meat product (or test product) showed higher monounsaturated fatty acid and tyramine levels and lower levels of sugars. The test meat product was used in a randomized controlled clinical trial to test for potential health effects in patients showing atherosclerosis symptoms. Patients receiving the test product showed a decrease in blood levels of low-density lipoproteins, total cholesterol, atherogenic index and triacylglycerols. To reduce the impact of animal production on ecosystems, the replacement of feed ingredients by a microbial alternative was realized. In this study, vegetable oils included in the feed of Arctic char (Salvelinus alpinus) were replaced by biomass of the oleaginous yeast (Rhodotorula toruloides). The analysis of the yeast biomass showed safe levels of pollutants and heavy metals. Fish growth and muscle fatty acid profile were similar to the control. A higher liver weight and hepatosomatic index were observed in fish fed including the yeast biomass, albeit no significant difference in liver fat content or in hepatic enzyme activity was observed. Quantification of plasma metabolites revealed higher levels of metabolites involved in energy pathways such as one-carbon metabolism and gluconeogenesis. In conclusion, this thesis showed that metabolomics can be applied to evaluate effects of food/feed at the molecular level in complex systems. It adds knowledge on the effects of meat by-product consumption in the particular case of atherosclerosis symptoms. The fish feed trial showed the possibility of feed modification with a specific yeast.

“…The heterogeneous photocatalyst is efficient for removing highly hydrophobic POPs from the environment. The surface, pore-volume, and structure of the semiconducting material are deciding parameters to consider while selecting the ideal catalyst [111,112]. The surface properties and crystal structure of the material can be tuned to boost the degradation efficiency of the photocatalyst [113].…”

Persistent organic pollutants (POPs) have become a major global concern due to their large amount of utilization every year and their calcitrant nature. Due to their continuous utilization and calcitrant nature, it has led to several environmental hazards. The conventional approaches are expensive, less efficient, laborious, time-consuming, and expensive. Therefore, here in this review the authors suggest the shortcomings of conventional techniques by using nanoparticles and nanotechnology. Nanotechnology has shown immense potential for the remediation of such POPs within a short period of time with high efficiency. The present review highlights the use of nanoremediation technologies for the removal of POPs with a special focus on nanocatalysis, nanofiltration, and nanoadsorption processes. Nanoparticles such as clays, zinc oxide, iron oxide, aluminum oxide, and their composites have been used widely for the efficient remediation of POPs. Moreover, filtrations such as nanofiltration and ultrafiltration have also shown interest in the remediation of POPs from wastewater. From several pieces of literature, it has been found that nano-based techniques have shown complete removal of POPs from wastewater in comparison to conventional methods, but the cost is one of the major issues when it comes to nano- and ultrafiltration. Future research in nano-based techniques for POP remediation will solve the cost issue and will make it one of the most widely accepted and available techniques. Nano-based processes provide a sustainable solution to the problem of POPs.

“…The selection of a certain bioremediation approach is made in close correlation with the soil characteristics, level of contamination, concentration of pollutant(s), biota availability, etc. (Valizadeh et al 2021;Karimi et al 2022;Yuan et al 2022). In a holistic approach, in-soil degradation of waste and bioremediation of soil are complex, interrelated processes, and both of them have significant environmental impact.…”

Vegetal fibers from different sources, including wood fibers and plant-derived fibers, together with polymer plastics per se (natural, synthetic, and their blends), as well as their combinations as composite materials may generate significant amounts of wastes. These will undergo degradation process under exposure to different environmental factors including microorganisms, climatic changes – e.g. droughts, oxygen, temperature, soil dynamics, UV radiation, etc. This survey offers a concise review of degradation under environmental conditions, mainly after in-soil exposure, of waste made of polymer materials and natural fibers. It also describes the most common methods for evaluation of bioconversion and degradation, as well as the structural properties after degradation (e.g. macroscopic investigation; weight loss; spectrometry – UV, FTIR, NMR; X-ray diffraction for crystalline changes; SEM microscopy; and thermal stability).
