| 摘 要： | 目的:研究成都、镇江、太原、天津4城市的成人膳食和血液中主要重金属的差异以及相关性。方法:用ICP-MS、双道原子荧光光度计测定膳食和血液中的5种重金属元素的浓度,并对重金属元素在城市间的差异以及血液与膳食中重金属的关系进行了统计分析。结果:4城市的成人膳食和血液中重金属含量差异有统计学意义,成都、镇江的膳食重金属含量高于太原、天津,但血液中的重金属含量成都、太原高于天津、镇江;血液中Cd、As分别与膳食中Cd、As的相关有统计学意义;除膳食中Hg与As的比值外,4城市成人血液、膳食中重金属比值差异均有统计学意义,血液与膳食间的多数重金属元素比值相关有统计学意义。结论:4城市成人膳食、血液中重金属含量差异一定程度上反映了城市环境的差异;膳食是血液中Cd、As重要来源,而血液中Cu、Hg、Pb可能与空气污染有关;重金属比值可能是反映血液和膳食中重金属间关系,以及环境污染状况的更好指标。 |
