  Hi Naumanaslam, Please note I am not a chemist but most test laboratories would use EN 71 Part3 to look for the presence soluble Aresenic, for total content they would use a Mass Spectrophotometer technique. If you need specific information relating Aresenic in Cotton you would be better contacting  Cotton Incorporated in the USA http://www.cottoninc.com
