Arsenic
Description
Research hypothesis: “Environmental occurrence and health risk assessment of arsenic in a Middle East country as a systematic review and meta-analysis study”. Iran is the third most populous state with over 82 million people in the Middle East. In Iran like many other countries, geogenic arsenic contamination could affect environmental and human health in some areas. The first case of chronic arsenic poisoning was recognized in Kurdistan province (west of Iran) in 1986. Then, other areas in Iran where there is arsenic contamination continue to be discovered. However, despite a body of valuable works investigating arsenic distribution in various environmental media, there is no comprehensive picture for Iran. So, our study aimed to establish a database and use systematic review and meta-analysis to quantify multimedia arsenic concentrations in this country. In order to better understand which media are more contributing to arsenic exposure of the national population, human health risk assessment was conducted. We think the information will be interesting for readers.
