An Estimation of Air Pollutant Emissions from Open Rice Straw Burning in the Red River Delta
Keywords
Air pollutant emission, environmental pollution, rice straw burning, Red River delta
Abstract
This study aims to estimate the air pollutant emissions into the asmostphere caused by open rice straw burning after rice crop harvest in the Red River delta. The results revealed that the emission of CO2 is the largest, between 1.2 – 4,7 million tons per annum when the burning rate varies from 20-80%. The emission of CH4 is between 1.0 – 3.9 thousand tons per year while CO pollutant emission is between 28.3 – 113.2 thousand tons per year. The GHG emission from open rice straw burning in the Red River delta could cause the environmental damage from 19.05 to 200.3 million USD per year depending upon on open rice straw burning rate (20-80%) and on the market price of CO2 emission right in the world. Enhanced use of rice straw for mushroom production, biofertilizer,and power generation... could be the relevant ways that should be studied for mitigating the open rice straw burning in the Red River delta in the coming time.
