Energy use and sulphur dioxide emissions in Asia

Article Abstract:

The total sulfur dioxide emission in Asia was estimated to be 38 mil tons in 1990, nearly 56% more compared to that of North America. The north-east Asian countries, China, Hong Kong, Japan, Mongolia, Taiwan, and South Korea accounts for about 78 percent of SO2 emissions. Over 80 percent of the total SO2 emissions are attributed to coal use in the region. Industrial sector accounts for 49 percent the SO2 emissions followed by the power sector which contributes 30 percent of the emissions. Check on the SO2 emissions calls for effective control measures.

Amelioration of sulphur dioxide phytotoxicity in wheat cultivars by modifying NPK nutrients

Article Abstract:

Wheat cultivars Malviya 206 and 234 when exposed to 0.15 ppm sulphur dioxide (SO2) for 4 hours per day for 45 days resulted in the reduction of plant length, leaf area, total plant biomass and yield. However, wheat plants with nutrient regime have been found to decrease the level of reduction. Moreover, plants grown under optimal levels of Nitrogen, Phosphorous and Potassium were able to relieve the SO2 induced injury to different extents depending upon the nutrient combinations.

Integrated assessment of sulphur dioxide reduction schemes: Robustness studies, choice of environmental targets and country roles

Article Abstract:

The Abatement Strategies Assessment Model (ASAM) is used to draw up cost effective measures for reducing emissions from sulphur dioxide in Europe, thus improving acidification. The ASAM allows for the needs of a particular environment.
