Article Synopsis
- Pantanal, a unique biome in Brazil, is rich in diverse plant and animal species, including native rice varieties Oryza latifolia and Oryza rufipogon, which are significant due to increased rice consumption worldwide, particularly in Asia and Africa.
- The average rice consumption is about 160 g/day, but it poses health risks due to potential ingestion of harmful substances like toxic metals.
- This study analyzed seven types of Brazilian rice for essential and toxic elements; findings indicated that chromium levels were highest in native species, and all varieties had risks associated with inorganic arsenic, highlighting the need for further research on contamination and its health implications.
This research evaluated the in vitro acaricidal activity of extracts from 21 plant species from the Pantanal of Mato Grosso do Sul. During stage I, a larval immersion test was performed using three extract concentrations (5%, 20%, and 40%). During stage II, we used only plants that showed over 95% efficiency at the 40% concentration in stage I in an amount sufficient for the adult immersion test.
