Microplastic abundance in atmospheric deposition within the Metropolitan area of Hamburg, Germany

Only few studies investigated the input of microplastic particles via the atmosphere, so far. Here, we present results on microplastic concentrations in the atmospheric deposition in the metropolitan region of Hamburg. In total, six investigation sites were equipped with three bulk precipitation samplers each and sampled biweekly over 12 weeks (12/17–03/18). Three sites were located in a rural area south of Hamburg comprising one open field site...
