Summary: Rice is a crucial staple crop for billions of people, but its consumption can lead to exposure to chemical contaminants such as mycotoxins and metalloids. This study evaluated the presence and human exposure to AFB1, OTA, ZEN, and InAs in Portuguese rice samples. AFB1 was found in 4.8% of the samples, exceeding the European MPL, while ZEN was present in 88.89% of the samples. InAs was detected in all samples, but none exceeded the MPL. There was no correlation between mycotoxin and InAs contamination. AFB1 exceeded the provisional maximum tolerable daily intake, with children being the most vulnerable group.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
