The effect of ozone on the removal effectiveness of ...

The degradation of d-limonene by UV/O3 was also investigated for comparison. The experiments were conducted with a quartz photoreactor under various gas flow rates (600-1600 mL min(-1)), d-limonene concentrations (0.5-9 parts per million [ppm]), and relative humidity (RH) (20-80%). The d-limonene removal efficiency of TiO2/UV/O3, TiO2/UV, and ...

PubMed

Both UV-B and O3 exposure enhanced similar Cu,Zn-superoxide dismutase isoforms. New isoforms of peroxidases and ascorbate peroxidase were synthesized in tt5 plants irradiated with UV-B. UV-B radiation, in contrast to O3, enhanced the activated oxygen species by increasing membrane-localized NADPH-oxidase activity and decreasing catalase activities.

The Greenhouse effect: impacts of ultraviolet-B (UV-B ...

The joint effects of UV-B, CO2 and O3 are poorly understood. Based on the literature of plant response to individual stress factors and chemical and physical climatology of North America, we conclude that nine different crops may be sensitive to the joint effects: three grain and six vegetable crops (sorghum, oat, rice, pea, bean, potato, lettuce, cucumber and tomato).

Treatment of winery wastewater by ozone-based advanced ...

11-05-2010 · The effectiveness of different ozone-based advanced oxidation processes (O 3, O 3 /UV and O 3 /UV/H 2 O 2) on the treatment of winery wastewater was investigated in a pilot-scale, bubble column reactor.At the natural pH of the wastewater (pH 4) the effectiveness of each AOP followed the sequence: O 3 /UV/H 2 O 2 > O 3 /UV > O 3 > UV-C. The rate of chemical oxygen demand (COD) and …

Effect of Elevated CO2, O3, and UV Radiation on Soils

06-02-2014 · In this work, we have attempted to review the current knowledge on the impact of elevated CO 2 , O 3 , and UV on soils. Elevated CO 2 increases labile and stabile soil C pool as well as efficiency of organic pollutants rhizoremediation and phytoextraction of heavy metals. Conversely, both elevated O 3 > and UV radiation decrease inputs of assimilates to the rhizosphere being accompanied by ...
