Perchlorate is an environmental contaminant that is found in drinking water and a variety of foodstuffs, but many questions regarding its uptake, transport, and persistence in higher plants remain unanswered. In a series of hydroponic experiments, a stable-isotope tracer of perchlorate (95% 37ClO4(-)) was utilized to determine the extent of in vivo metabolism and of phloem re-translocation of perchlorate at low (i.e., nmol/kg of fresh weight (FW)) concentrations in lettuce. Chlorate and… CONTINUE READING
