内容記述 | 石川県金沢市藤江の幹線道路脇において12年間(1999~2010年)の夏と冬の大気粉塵を捕集し、多環芳香族炭化水素(PAH)6種類(pyrene、benz[a]anthracene、chrysene、benzo[b]fluoranthene、benzo[k]fluoranthene、benzo[a]pyrene)およびニトロ多環芳香族炭化水素(NPAH)7種類(1,3-、1,6-、1,8-dinitropyrenes、1-nitropyrene、6-nitrochrysene、7-nitrobenz[a]anthracene、6-nitrobenzo[a]pyrene)をそれぞれHPLC-蛍光検出法、HPLC-化学発光検出法で測定し、その変遷を明らかにした。この間に、PAH濃度は冬63.9%、夏75.6%減少、NPAH濃度は冬88.0%、夏89.2%減少した。また[1-NP]/[Pyr]値は冬と夏ともに著しく減少した。自動車排ガス規制の強化によって排出源としての自動車の寄与率が低下したことが、大気中PAH、NPAH濃度および[1-NP]/[Pyr]値が顕著に減少した主要因と考えられた。 Airborne particulates were collected at a roadside site in Kanazawa, Japan, in the summer and winter, 1999, 2004/2005, 2007/2008 and 2010. The polycyclic aromatic hydrocarbons (PAHs) and nitropolycyclic aromatic hydrocarbons (NPAHs) were determined by HPLC with fluorescence and chemiluminescence detections, respectively. The total concentration of six PAHs (pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene and benzo[a]pyrene) decreased by the factor of 63.9% in the winter and 75.6% in the summer from 1999 to 2010. The total concentration of seven NPAHs (1,3-, 1,6-, 1,8-dinitropyrenes, 1-nitropyrene, 6-nitrochrysene, 7-nitrobenz[a]anthracene and 6-nitrobenzo[a]pyrene) significantly decreased by the factor of 88.0% in the winter and 89.2% in the summer during the same period. The concentration ratio of 1-nitropyrene to pyrene also significantly decreased in this period, suggesting a decrease in the emission amount.
