“…By integrating both epidemiological and toxicological perspectives, our study provides a holistic and comprehensive view of the multifaceted risks posed by PFAS exposure. This approach allowed us to draw connections between real-world health trends observed in human populations and the mechanistic insights gained from controlled laboratory experiments using in vivo rodent models [28] [29].…”

This research provides a comprehensive analysis of the health impacts of Perand Polyfluoroalkyl Substances (PFAS) through an integration of epidemiological and toxicological studies. The study identifies significant correlations between PFAS exposure and adverse health outcomes, including thyroid dysfunction, elevated cholesterol levels, and increased risk of specific cancers. Utilizing a mixed-methods approach, the research combines a systematic review and meta-analysis of recent literature with in vitro and in vivo toxicological experiments. The epidemiological analysis reveals increased risks of thyroid dysfunction, cholesterol elevation, and certain cancers among PFASexposed individuals. Toxicological findings further corroborate these results, showing dose-dependent cytotoxic effects in human cell lines and endocrine disruption in rodent models. The study emphasizes the importance of regulatory measures to mitigate PFAS exposure and the urgent need for more comprehensive research into their long-term effects. The integration of epidemiological and toxicological data underscores the significant health risks posed by PFAS, highlighting the necessity of immediate action to limit exposure and develop safer alternatives.

“…The sample is fragmented at a temperature between 500 and 1400 °C in the presence of helium and at low pressure, creating fragments that are introduced into the GC system. No sample pretreatment is required and the amount of sample can be within the range of 5–200 μg [ 91 , 94 , 95 ]. This methodo-logy makes it possible to simultaneously identify the type of polymer and organic filler and determine the chemical composition of MPs using spectral libraries and databases.…”

“…Nuclear magnetic resonance (NMR) spectroscopy is used to identify MPs because it provides information about the molecular structure, crystallinity, and branching of monomers in copolymer compounds [ 10 , 91 , 95 ]. The principle of NMR is that the magnetic properties of atomic nuclei are used to obtain chemical information.…”

Microplastics are small plastic pieces with sizes less than 5 mm. They are becoming a global concern due to the potential risk to human health. The potential risks of microplastics may be greater for infants because they do not have sufficiently developed metabolizing enzymes, have less ability to remove microplastics, and have highly sensitive target organs. Infants should be breastfed for the first six months of life. Breast milk is considered to be the most complete and suitable source of nutrition. However, if breastfeeding during this period is not possible, it is necessary to use formulas designed for infant initial feeding. Infants may be exposed to higher levels of MPs through infant foods or plastic products. The aim of this study is to describe the possible sources of exposure to microplastics such as the human placenta, plastic feeding bottles, and toys as well as the presence of released microplastics in infant feces, breast milk, and infant formulas. There is still not enough data available for this study area. Therefore, it is necessary to pay increased attention to minimizing the negative effects of microplastics on human health.

“…The positive value of entropy (ΔS°) of 54.41 J/(mol K) indicates that the system is becoming more disordered, while a negative value of Gibbs free energy (ΔG°) indicates a spontaneous and thermodynamically favorable process. Therefore, it can be concluded that the adsorption of DZN onto PE MPs is an exothermic, highly disordered, and spontaneous process (Jiménez-Skrzypek et al 2021).…”

MPs have raised significant public concern due to their role as carriers of organic contaminants in aqueous solutions. DZN is a non-systemic organophosphorus pesticide that poses risks to human and environmental health. This study aimed to investigate the adsorption of DZN onto PE MPs by examining factors such as PE dose, reaction time, pesticide concentration, and pH through experimental runs based on the Box‒Behnken model. According to the Langmuir model, the maximum adsorption capacity of PE for DZN was 0.35 mg/g. The results indicated that the highest adsorption rate of DZN (92%) was observed in distilled water, while the lowest adsorption rate (57%) was observed in municipal wastewater. The ΔH° and ΔS° values were obtained as − 0.16 kJ/mol and 54.41 J/(mol K), respectively. Therefore, regarding negative ΔG° values, it can be concluded that the adsorption of DZN onto PE MPs is an exothermic, highly disordered, and spontaneous process. The findings indicate a reduction in the adsorption rate of DZN as the concentrations of interfering compounds increase. These findings offer understanding of the interaction between MPs and organic contaminants, emphasizing the need for further studies and approaches to reduce their harmful impact on human health and the environment.
