Summary: The study assessed alterations in thyroid function and serum lipid levels in relation to exposure to PCBs and three chlorinated pesticides in Akwesasne Mohawk adults. The findings suggest only small and inconsistent associations between serum PCB levels and thyroid function, with the most significant observations being strong positive associations between TSH and T3 with serum lipids, and a negative association with fT4 in women. Further research is needed to understand the respective roles of thyroid hormones and PCBs in regulating serum lipids.

Summary: Exposure to radiofrequency electromagnetic radiation from mobile phones and Wi-Fi devices can have negative effects on male reproductive hormones, potentially leading to a reduction in testosterone levels. However, the impact on gonadotrophic hormones is still inconclusive, with studies showing conflicting results influenced by various factors such as energy absorption and duration of device use. Therefore, limiting the use of wireless devices is recommended to minimize potential risks to male reproductive function.

Summary: Most ovulation prediction kits currently available only provide a rough estimation of ovulation time and do not track the post-ovulation period. This exploratory study found that non-intact LH immunoreactivity derived from degradation products remains detectable at peak levels from LH surge until ovulation and during the early postovulatory period. This suggests that non-intact U-LH-ir could be a promising marker for evaluating the post-surge segment of the fertility window.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.
