It is reported ' Reporter Sun GuoGen) Recently, the top periodical of international environmental scientific circles - -Magazine of " environmental science and technology " issued relevant straws and burnt and formed air pollution " Quantitative to melt and study " Newest achievement. This research reveals, only 2004, reaches 23 million, 250 million tons of and 280,000 tons respectively if the corn, wheat, 3 kinds of crops straws of rice burn the gaseous pollutant CO, CO2 and NOx total amount discharged; The national straw was burnt and discharged " Multiloop aromatic hydrocarbon " With " multiloop aromatic hydrocarbon of alkyl " The total amount of waiting for the harmful substance is 1088 tons and 379 tons respectively. This research is called " the tiny particle spreads the multiloop aromatic hydrocarbon discharge in burning with the agricultural straw ", headed the list of signers in the seminar to finish by Chen Jianmin, Professor of Fudan University Department of Envorinmental Science and Engineering. Chen Jianmin introduces, so far, our country burns and " contributes " the air pollution in the straw of the crops , the measurement of influence degree of air quality monitors the respect, has been lacking the quantitative research approach to melt all the time. The seminar, through designing large-scale aerosol smog case, specialized combustion furnace and advanced atmospheric particulate matter of sign,etc. measuring system developed by oneself, to the intersection of our country and 3 main the intersection of crops and straw ' Corn, wheat, rice) Output and burning the proportion situation, provide straws and burn melting to discharge the characteristic accurately and quantitatively of gaseous pollutant, particulate matter and multiloop aromatic hydrocarbon of multiloop aromatic hydrocarbon and alkyl discharged. Meanwhile, this research shows in discharging the analysis of geographical distribution of the intensity, the agricultural straw burns and discharges " multiloop aromatic hydrocarbon " With " multiloop aromatic hydrocarbon of alkyl " It is Henan Province at most; The largest one is Shandong that the particulate matter discharges the intensity.
