STATISTICAL
This study was used software SPSS v.18 for the descriptive and inferential data analysis. Descriptive statistics were number and percentage to describe the personal characteristic such as age and body mass index. The arsenic contamination in soil, water and urine didn’t show in mean value because max and min value of the contamination was very different and did not show normal distributions. So the median and inter quartile range (IQR) were used to describe the arsenic contamination in soil, water and urine [17]. Inferential statistic was the Mann-Whitney U test statistic for comparing the difference of arsenic in urine and environment between two groups. Spearman’s rho correlation test was used to compare and describe the relationship of urinary arsenic level with arsenic contamination in environment and behavioral factors.
