岳麓山空气负离子及空气质量变化研究

采用空气离子测量仪,于2003年10月～2004年9月对岳麓山及其周围地区的空气正、负离子浓度进行了测量,并用相应的方法对其空气质量作了评价.结果表明,岳麓山正、负离子之比的单极系数q值较小,空气离子评价系数CI值均大于0.7,空气质量良好;空气负离子浓度的垂直变化明显,山体中部明显高于山顶和山麓地带,且非核心景区高于核心景区;空气负离子浓度和空气质量1月最低,9月最高,夏、秋两季相当,春季好于冬季;空气负离子浓度的日变化规律(6:00～19:00)为清晨和中午低,上午和傍晚高,一天中存在2个峰值;下雨后空气负离子浓度和空气质量要好于下雨前,两者差异显著.而晴天空气负离子和空气质量要略好于阴天,但两者差别不明显;不同功能区空气负离子浓度和空气质量差异显著,其大小依次为:风景区＞大公园＞小公园＞商业区＞一般交通线＞交通干线＞汽车站.     

Uptake and accumulation of phenanthrene and pyrene in spiked soils by Ryegrass(Lolium perenne L.)

Phytoremediation has long been recognized as a cost-effective method for the removal of polycyclic aromatic hydrocarbons （PAHs） from soil. A study was conducted to investigate the uptake and accumulation of PAHs in root and shoot of Lolium perenne L. Pot experiments were conducted with series of concentrations of 3.31-378.37 mg/kg for phenanthrene and those of 4.22-365.38 mg/kg for pyrene in a greenhouse. The results showed that both ryegrass roots and shoots did take up PAHs from spiked soils, and generally increased with increasing concentrations of PAH in soil. Bioconcentration factors（BCFs） of phenanthrene by shoots and roots were 0.24- 4.25 and 0.17-2.12 for the same treatment. BCFs of pyrene by shoots were 0.20-1.5, except for 4.06 in 4.32 mg/kg treatment, much lower than BCFs of pyrene by roots （0.58-2.28）. BCFs of phenanthrene and pyrene tended to decrease with increasing concentrations of phenanthrene and pyrene in soil. Direct uptake and accumulation of these compounds by Lolium perenne L. was very low compared with the other loss pathways, which meant that plant-promoted microbial biodegradation might be the main contribution to plant-enhanced removal of phenanthrene and pyrene in soil. However, the presence of Lolium perenne L. significantly enhanced the removal of phenanthrene and pyrene in spiked soil. At the end of 60 d experiment, the extractable concentrations of phenanthrene and pyrene were lower in planted soil than in non-planted soil, about 83.24%-91.98% of phenanthrene and 68.53%-84.10% of pyrene were removed from soils, respectively. The results indicated that the removal of PAHs in contaminated soils was a feasible approach by using Lolium perenne L.
