Summary: This study analyzed the concentration of PAEs in fruit juice samples and conducted a risk assessment on their potential non-carcinogenic and carcinogenic effects. The results showed that PAEs were detectable in the samples but remained below the specific migration limits set by the EU. Health risk assessments based on consumption patterns indicated negligible non-carcinogenic health risks associated with the consumption of fruit juices across all age groups.

Summary: This study reports the levels of bisphenol A (BPA) and bisphenol S (BPS) in eight different types of dialyzers currently on the market. BPA and BPS were detected in dialyzers made with BPA- and BPS-containing materials, except for one new type of dialyzer. Based on the established tolerable intake, the margin of safety suggests that adverse effects are unlikely to occur in hemodialysis patients exposed to BPA and BPS quantified in this study. However, the safety limits of BPA and BPS in these dialyzers may need to be re-evaluated in the future as more data and information about their toxicity become available.

Summary: Animal-derived food plays a significant role in human exposure to bisphenol compounds, with limited studies on the source of bisphenols in animal feed. This study examined the occurrence of BPs in animal feed packaging and their migration into feed, confirming that BPA can migrate from plastic packaging into solid feed. Results show that contact time and initial BP concentration affect the migration extent, expanding knowledge on the origin of BPs in the food chain.

Summary: Based on breastmilk samples collected from 9 provinces in China in 2014, it was found that BPA was the predominant BP, followed by BPF and BPS. There were no differences in BPA, BPF, BPS, or total BP levels between urban and rural regions or northern and southern regions. The high contribution of BPF in breastmilk samples, accounting for over 20%, indicates the need for attention to BPA analogues.

Summary: There is increasing scientific evidence that certain pharmaceuticals are present in marine ecosystems at concentrations that can have adverse effects on the organisms that inhabit them. However, there is currently limited scientific literature on the accumulation of these compounds in different species, as well as the relationship between their presence and the adverse effects they cause. Efforts have been made to optimize and validate analytical methods for determining pharmaceutical residues in marine organisms through the study of sample treatment, cleanup, and subsequent analysis. This literature review provides a summary of commonly used techniques and their analytical features for determining pharmaceutical compounds in aquatic organisms at various trophic levels over the past 10 years.

Summary: There is growing evidence that certain pharmaceuticals in the environment pose a potential risk to ecosystems through biota exposure. This review aims to summarize the research and factors involved in assessing the bioaccumulation of pharmaceuticals in aquatic organisms, and provide a critical review of the bioconcentration and bioaccumulation factors of these compounds in different trophic levels. The most commonly studied pharmaceuticals are antidepressants, followed by diclofenac and carbamazepine. Field studies yield more reliable data than laboratory tests for assessing the true environmental impact.

Summary: This study evaluated the occupational exposure to PAHs in a specific petroleum refinery in Albania. The main exposure route was inhalation in a highly contaminated work environment. Serum samples from workers were collected and analyzed. A cloud-point extraction method was used to isolate and concentrate PAHs from samples. Gas chromatography/mass spectrometry analysis showed that the PAHs present in the serum were primarily pyrogenic PAHs. The bioaccumulation trend of the PAHs in the workers was found to be dependent on their physical location within the workplace.

Summary: The bioconcentration kinetics of atenolol and carbamazepine in marine organisms were assessed under controlled laboratory conditions. Carbamazepine showed higher uptake and excretion rates, resulting in a higher bioconcentration factor (BCF), while both were below the limits set by the European Union. The measured BCF using kinetic data showed differences compared to those predicted using steady-state concentrations, possibly due to the steady state not being reached. Specific to the organisms, atenolol exhibited different bioconcentration patterns in different species, with Holothuria tubulosa having the highest BCF. The study also highlighted tissue differences within Holothuria tubulosa. This work is the first to model the bioconcentration of atenolol and carbamazepine in holothurians and anemones.

Summary: The study aimed to investigate the impact of different oils (EVOO, refined olive oil, HOSO, and RSO) and intermittent deep-frying on the levels of GD, MCPDs, and AA in pre-fried French fries. The results showed that the content of MCPDs, GD, and AA were influenced by the time and type of oil used. The migration of MCPDs and glycidols in French fries during frying was observed, along with the formation of new compounds. EVOO exhibited the lowest MCPDs and GD content, while HOSO resulted in the lowest AA levels.

The results suggested that BPF in nails was associated with overweight/obesity in children, while the highest concentrations of BPAF in saliva showed an inverse association. No significant associations were found between exposure to BPA or its analogs and overweight/obesity in other biological matrices.

Summary: The continuous contamination of the environment by a high variety of pollutants is a global concern. Among these pollutants, endocrine disrupting chemicals (EDCs) are particularly problematic due to their persistence and toxicity. Conventional treatments are not sufficient to remove EDCs, making bioremediation a promising alternative. Microbial communities, enzymes, and fungi have shown potential in efficiently transforming EDCs into non-hazardous end products. Certain aerobic bacteria such as Sphingomonas, Achromobacter, and Pseudomonas have proven to be highly effective in removing EDCs such as nonylphenols, bisphenols, and parabens.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.

Summary: This work proposes a rapid and sensitive spectroscopic method for detecting melamine in food products using rare-earth Terbium-doped Graphene Quantum Dots (Tb-GQDs) synthesized by microwave and simple chemical conjugation methods. The synthesized Tb-GQDs show a spherical shape with a size of approximately 6 nm and a quantum yield of 52%. The maximum detection limit for melamine concentration in milk and milk products is found to be 0.31 μM. The dual emitting Tb-GQDs provide a sensitive and effective platform for real-time detection of melamine in food samples, particularly in milk, and show promising potential in the food industry.
