Ecotoxicology of phenylphosphonothioates.

abstract：BACKGROUND:The upward trend in industrial nations in the incidence of male genitourinary (GU) conditions may be attributed to increased exposure to endocrine disruptors. Polybrominated biphenyl (PBB), a brominated flame retardant, is one such suspected endocrine disruptor. OBJECTIVE:We investigated the relationship be...
