endosulfan diol is then degradated into a set of related metabolites, including endosulfan ether, endosulfan hydroxyether, endosulfan carboxylic acid, and endosulfan lactone.
of them, 109 substances were predicted to end up as perfluorinated sulfonic acids, including pfos, and 61 as perfluorinated carboxylic acids (dimitrov et al., 2004).
