arsenic intakes from spices and sheep tail (donbeh) in a high oesophageal cancer area: pilot study from iran

arsenic is a carcinogenic and toxicant element widely found in the environment and might be part of causation web of oesophageal cancer (oc), which has one of the highest incidence rates in golestan province, northeast iran. in this pilot study, we collected 10 sheep tail (donbeh) and 9 mixed spices samples, as widely consumed foods in the region, from main counties in the province and analyzed for arsenic concentrations using aoac atomic absorption spectrophotometry method. findings showed that arsenic levels in all samples were less than the safe level of 1 ppm. total arsenic intake from sheep tail and mixed spices sources were estimated at 4.68 and 4.24 µg/day in men and women, respectively. therefore, the study suggests that arsenic intake from these commonly consumed foods do not seem as a major hazard for oc etiology.
