AB  - In this study, pigmentation (Chlorophyll a, Chlorophyll b and carotenoid),bioaccumulation, and oxidative stress response upon boron particles exposurewere investigated in Chodatodesmus mucronulatus, unicellular algae. The Effectsof acute exposure was measured by growing algae in BG-11 media supplementedwith varying concentrations of boron particles for 72 h. Nano boron has increasedchlorophyll content for 48 h. However, as exposure time was prolonged, nanoboron was toxic to the algae. Micro boron particles also indicated similar effects.Nano boron increased chlorophyll b at 48 hours. On the other hand, levels ofchlorophyll b seem to decrease for the remaining part. Bioaccumulation of theboron particles did not notably change upon varying particle concentration. Nanoboron particles toxicity is conclusively seen at 72 h of exposure. Additionally,nano boron particles are concluded to be more toxic than micro boron to theChodatodesmus mucronulatus.
