摘要
Microwave digestion-inductively coupled plasma mass spectrometry(ICP-MS)was used to analyze the sources of lead in farmland soil and rice in the Jiulongjiang River Basin.The results suggested that the source of lead in rice was differ from that in soil.There were four main sources of lead in farmland soil:natural source,agricultural source,industrial source and fossil fuel source,among which natural source,agricultural source and industrial source contributed more.There were four main sources of lead in rice:natural,agricultural,industrial and fossil fuel sources,and more importantly,fossil fuel sources.The comparison of lead isotope composition with potential sources(^(206)Pb/^(207)Pb,^(208)Pb/^(206)Pb,^(208)Pb/^(207)Pb)can provide a scientific basis for the identification and treatment of heavy metal lead pollution sources in farmland soil and rice in the Jiulong River Basin.
