TL;DR: In this article, an in vitro study involving the use of high-performance liquid chromatography equipped with an electrochemical detector (HPLC-EC) showed that EDU does not serve as an antioxidant to remove OH free radicals.

TL;DR: In a field experiment with rice (Oryza sativa L. cv. Saket 4) grown under ambient and supplemental ultraviolet-B (UV-B) radiation at 20 % ozone depletion, differences in gas exchange, concentrations of photosynthetic pigments, anthocyanins and flavonoids, biomass accumulation, catalase and peroxidase activities, and contents of ascorbic acid and phenol were determined as mentioned in this paper.
Abstract: In a field experiment with rice (Oryza sativa L. cv. Saket 4) grown under ambient and supplemental ultraviolet-B (UV-B) radiation at 20 % ozone depletion, differences in gas exchange, concentrations of photosynthetic pigments, anthocyanins and flavonoids, biomass accumulation, catalase and peroxidase activities, and contents of ascorbic acid and phenol were determined. Decline in photosynthesis was associated with reductions in stomatal conductance and concentrations of photosynthetic pigments. Enhanced UV-B radiation (eUV-B) increased the contents of flavonoid and phenolic compounds in leaves. Peroxidase activity increased and catalase activity was always lower at eUV-B. The total plant biomass decreased at eUV-B.

TL;DR: Soil mineral nutrient status has been found to modify the response of wheat plants and yield data have suggested that Malviya 234 is more responsive to nutrient status and showed lower reductions due to SO2exposure.

TL;DR: In this article, the authors quantify the spatial and temporal variations in the concentrations of total suspended particulate matter and dust fall rate around a cement factory situated in a dry tropical area.
Abstract: Air quality monitoring was conducted to quantify the spatial and temporal variations in the concentrations of total suspended particulate matter and dust fall rate around a cement factory situated in a dry tropical area. Particulate matter showed a linear spatial decrease as one moves away from the source. Concentrations of TSP often exceeded permissible limits up to 2 km SE of the source. Dust fall rate was quite significant up to 5 km SE. Dust fall rate was maximum during winter, while TSP levels were maximum during summer.
