Environmental assessment of engineered nanoparticles (ENPs) and engineered nanomaterials (ENMs) suffer of lack of data on production, emission, transfer, behaviour, toxicity, ecotoxicity and fate in natural compartments. This paper tries to bring factual data of production, content and emission of elements in a colloidal form or in an ENP form from some products, and two waste potential sinks: municipal sewage sludge and non hazardous waste landfill sludge (part of the landfill leachate decanted and concentrated to produce a liquid or solid sludge). The study is focused on mineral ENPs, since routine analytical methods are not available for organic ENPs in complex waste leachates. The declaration of production and importation of ENPs in France in 2014 (400 000 t) include carbon black (> 100 000 t/y), organic pigments (1 250 – 12 500 t/y), miscellaneous organic substances (575 – 5 750 t/y) and mineral ENPs classified here as...
