Survey of Arsenic concentration in the goat's blood, wool and liver at Kurdistan Province, Iran

In Ghorveh area, city of Kurdistan provinces in Iran, there are channels of arsenic and other geogenic toxic chemical compounds. The aim of this study is to determine the level of arsenic in goat`s blood, wool and liver at Ghorveh and other villages.  ۵۵ goats including both sexes in the age groups less than ۱ year, ۱-۳ years and above ۳ years were randomly chosen, and their blood and wool were collected as samples of the study, in addition to these samples ۱۰ goat’s liver also were taken from the slaughterhouse of the mentioned area to be examined. The results indicated that arsenic concentration in the sample’s blood was significant higher than normal levels (Mean values are more than ۱۲.۰۳۸±۵.۰۲۵ ppb comparing to the normal amount that is ۲.۹۲ ppb), which shown significant difference statistically (p≤۰.۰۵). The mean concentration of arsenic in the wool and liver of goats are ۱۸.۵۶۶±۱۰.۰۲۶ ppb and ۹.۸۲۳±۳.۲۴۵ ppb respectively, which in comparison to the normal concentrations do not show significant difference statistically (p≥۰.۰۵). Also there is no significant correlation between arsenic concentration existing in the goat’s blood, wool and liver and variables of age and sex (p≥۰.۰۵).However, being high level of arsenic concentration in the blood of goats reveals the high level of arsenic in the environment and food of Ghorveh area which can be a serious threat to public health and other creatures. So, it is advised to do further and comprehensive studies in large scale.
