The use in folk medicine of and recent studies on DNA damage by oxidative stress mechanisms have motivated this study. We investigated the biotoxicological effects of trimeroside from this plant. Aqueous extract from aerial parts of was fractioned by flash chromatography for further isolation by thin-layer chromatography.

Article Synopsis
- Coal extraction emits significant amounts of coal dust, which is harmful and exposes miners to potential genotoxic effects and oxidative stress.
- A study of 128 male participants showed that those exposed to coal had increased DNA damage and micronucleus frequencies compared to unexposed individuals.
- Despite some biochemical differences, such as increased superoxide dismutase activity in exposed individuals, the findings highlight the urgent need for protective measures and educational programs for coal miners to mitigate these health risks.
During coal combustion, hazardous elements are discharged that impair environmental quality. Plant cover is the first available surface for the atmospheric pollutants in terrestrial ecosystems. The aim of this study was to evaluate genotoxicity in the aqueous extract of the native plant, Baccharis trimera, exposed to coal and emissions from a thermal power plant (coal-fired power plant in Candiota, Brazil), correlating seasonality, wind tunnel predominance, and presence of inorganic elements.
