title: [A study on the relationship between malignant tumour mortality and environmental pollution in Beicun countryside of Datong City].
abstract: The paper reports investigations on malignant tumor mortality in Beicun countryside of Datong city, with Hua yuan tun countryside as the control group. The result showed that malignant tumor mortality (117.04/10(5)) in Beicun countryside was significantly higher than that in the control group (61.06/10(5)). The nitrate and nitrite in drinking water and five kinds of vegetables in Beicun countryside were significantly higher than those in the control group (P < 0.05 - P < 0.001). Serum Cu and Cu/Zu levels in the inhabitants of Beicun countryside were significantly higher than those in the control group (P < 0.001 and P < 0.01). The benzo (a) pyrene and airborne particulates in Beicun countryside area were higher than those in the control group area. The results showed that the malignant tumor mortality was strongly correlated with severe pollution of vegetables, drinking water and air.
