通过对奇东公路沿线的108团和奇半公路沿线的109团公路两侧土壤和甜瓜铅含量的研究发现,在公路两侧50 m以内、50~100 m范围汽车尾气明显增加了土壤和甜瓜的铅含量;单因素方差分析检验结果表明污染区、次污染区及对照区的土壤铅含量、坐果期甜瓜铅含量、成熟期甜瓜铅含量均有显著差异;相关性分析表明:土壤铅含量、坐果期甜瓜铅含量、成熟期甜瓜铅含量间有极显著的正相关性。
Through the study on the lead contents in soils and melons on the 109th mass road along the 108th and Qibeal along the Qidong Highway, it was found that within 50m on both sides of the highway, the tail gas of 50 ~ 100m range significantly increased soil and melon The results of one-way ANOVA showed that there were significant differences in soil lead content, lead content in melon fruit and melon in ripening time in the polluted area, secondary polluted area and control area. Correlation analysis showed that the contents of lead, There was a significant positive correlation between lead content in melon during fruit setting and lead content in melon at maturity.
