摘要:
采用萘(Nap)、菲(Phe)、荧蒽(Flt)、苯并(a)芘(BaP)和茚并(1,2,3-cd)芘(InP)5种不同苯环数的多环芳烃(PAHs)混合溶液施入土壤,制成不同浓度PAHs污染土壤盆栽种植菜心,研究菜心对土壤中不同种类PAHs的吸收和积累规律。结果表明,菜心根部、茎部、叶片中的PAHs含量随着PAHs处理浓度的增加而升高;菜心植株内不同部位的PAHs含量表现为:根部>叶片>茎部;菜心叶片中的PAHs含量在定植后17 d内快速上升,17~24 d上升速度明显减慢,定植后24 d低浓度处理和CK叶片中的PAHs含量出现下降趋势。菜心植株中低环类PAHs(2~3个苯环)的含量占PAHs总量的77.61%~90.3%,高环类PAHs(4~6个苯环)的含量占PAHs总量的9.70%~22.39%。菜心植株对土壤中5种PAHs的富集能力大小为Phe>Nap>Flt>BaP>InP,菜心根部对BaP和InP的富集能力远大于茎部和叶片。
