hi ,i work as tubing inspector in Bahrain.we inspect used tubing of 2 3/8"e; dia on-site during pull-out.frequently we have to clean off physically those black sticky oily residue on the outer surface of tubing.my question is will this black residue from oil well posses any health risks like radio activity or cancer causing chemicals or asbestos content which are long term health risks.?
