Summary: This study conducted a survey in the Mekong Delta and found no relationship between rice arsenic concentration and speciation with soil levels, but a strong correlation was observed between rice and groundwater arsenic concentrations. The study hypothesizes that surficial sediments with high concentrations of arsenic may serve as sources of arsenic to downgradient shallow aquifers.

Summary: Dietary supplements sourced from marine environments, such as fish oils and seaweed-based supplements, can be a potential source of arsenic exposure. A study found high total arsenic concentrations in supplements made from seaweed, krill, and calanus oil, as well as in unprocessed fish and fish liver products. Inorganic arsenic was detected only in seaweed samples, while arsenic hydrocarbons were found in unprocessed fish and fish liver oil, and calanus oil. Pregnant women who consumed fish oil supplements had higher urinary arsenic concentrations, including arsenobetaine and dimethyl arsenic.

Summary: The study investigated the pattern of arsenic uptake and its influence on plant growth in bean and lettuce at different developmental stages. The human health risk from consuming these arsenic-laced vegetables was also determined. The results showed that arsenic had an impact on the biomass of plant parts, but the changes were not significant. The concentration of arsenic in the plants increased with the increase in arsenic concentration in the irrigation water. Lettuce had higher transfer factor at the young stage, while bean had the highest transfer factor at the flowering stage. The concentration of arsenic in lettuce was significantly higher than that in bean, posing significant health risks.

Summary: In this study, the agglomeration behavior and fate of food-grade titanium dioxide (E 171) in human gastrointestinal digestion (GID) were thoroughly investigated using various physicochemical techniques. The study revealed that TiO2 particles were resistant to GI dissolution and showed potential for bioaccumulation. Additionally, single-particle ICP-MS (spICP-MS) was used to characterize the agglomeration degree in the small intestine, demonstrating that E 171 remains dispersed in the small intestine at concentrations reflecting human exposure.

Summary: Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) evaluated the safety of a carotenoid-rich extract from yellow/orange tomatoes, which is proposed to be used as a novel food ingredient. The extract contains phytoene, phytofluene, beta-carotene, zeta-carotene, and lycopene, and is produced through supercritical CO2 extraction. The applicant intends to use the extract in cereal bars, functional drinks, and as a food supplement for individuals above 15 years old. However, due to insufficient safety data and potential exceedance of acceptable daily intake for lycopene, the Panel concluded that the safety of the extract has not been established under the proposed conditions of use.
