[Estimation of arsenic accumulative intake and residents' health effects in an air pollution area--relationship between arsenic accumulative intake level and arsenicism prevalence].
This paper reports the results of epidemiological survey on health effects of residents exposed to arsenic in a pollution area and estimation of arsenic accumulative intake level (EAAIL) based on calculating accumulative rice consumption and via inhalation way. 795 persons were sampled randomly from the polluted area, among whom 674 persons and 83 persons were diagnosed with Chronic Arsenic Absorption (CAA) and Chronic Arsenicism (CA) according to the National Diagnose Standard respectively. There were 60.98% CAA in 30 years old and younger age-groups and 97.59% CA in 30 years old and older age-groups. The one youngest case of CA occurred in 15 years old age group, while its EAAIL was at 1846.47 mg. The highest EAAIL was at 8706.47 mg. The rate of CA had gone obviously up at 30 years old age group. Its EAAIL was at 3833.42 mg. One equation of relationship between the rate of CA (%) and EAAIL (mg) was fitted by means of curve fitting, its is followed: Y = X1.843/e12.694 -2.866, r2 = 0.945.
