ABSTRACT
Thirty-four metals were analyzed by ICP-MS. Among these elements, anthropogenic silver, gadolinium and platinum, were representative markers of medical activities in hospital and urban wastewater. On working days, median hospital wastewater concentrations for anthropogenic silver, gadolinium, and platinum were approximately three, 13 and 27 times higher respectively than the Municipal wastewater. A drastic reduction of their emission was observed during non-working days (minus 94 % for gadolinium and 87 % for platinum). A large percentage of these metals are not trapped in the Treatment Plant, i.e. 88 % for gadolinium and 69 % for platinum. More than 4 kg and 350 g for gadolinium and platinum are respectively discharged per year in the River Seine. Therefore, it is imperative to eliminate these elements in the Plant.
