Article Synopsis
- Current chemical safety assessments often overlook that humans and ecosystems are exposed to multiple chemicals simultaneously, leading to potentially harmful unintentional mixtures that can endanger the environment.* -
- The study utilized the NORMAN database to analyze cumulative environmental risks in European freshwater ecosystems, finding that a significant percentage (39%) of monitored sites exhibited mixture risks exceeding safety thresholds.* -
- The findings suggest that even small reductions in chemical concentrations can significantly improve the protection of water bodies, highlighting the importance of integrating mixture assessments into regulatory frameworks for better environmental safety.*
Humans are exposed to bisphenol A (BPA) mainly through the diet, air, dust, skin contact and water. There are concerns about adverse health effects in humans due to exposure to bisphenol A (BPA). The European Food Safety Authority (EFSA) has extensively reviewed the available literature to establish a temporary Tolerable Daily Intake (t-TDI).

Experiments have been performed on interstellar ice analogues under ultra high vacuum conditions by molecular deposition at 14 K on a gold surface. A combination of reflection absorption infrared spectroscopy (RAIRS) and temperature programmed desorption (TPD) is used to derive spectroscopic and thermodynamic properties of the ices.

This study presents the first systematic infrared characterisation of the A. vinosum enzyme, with emphasis on the spectro-electrochemical properties of the inactive/active transition.
