Humans are potentially exposed to microplastics through several exposure pathways including food, drink, and air. So far little is known about the occurrence of microplastics in indoor environments especially in connection with industrial activities dealing with the use of raw materials potentially enriched with micron sized plastics.
In the present study, the indoor air of an industrial unit turning sewage sludge into fertilizer products has been characterized for microplastics content. Collected samples have been investigated by both a thermo-analytical method (pyrolysis-GCMS) and a vibrational microscopy (µ-FTIR) method
