Fig. 2From: Paradigms to assess the human health risks of nano- and microplasticsEstimating <1 μm NP concentrations by rescaling >1 μm MP concentration data to the nanoscale, using empirical particle size distributions spanning both nano- and microplastic size ranges. Error propagation (not shown) is accounted for via Monte Carlo simulations. For this proof of principle graph, data were taken from Lambert and Wagner [224]Back to article page
