“…These stems from ecotoxicology assays, where fullerenes were observed to cause the immobility of the water flea Daphnia magna (Lovern and Klaper, 2006) and packing in the gut thus causing high concentrations in the organisms' wet mass basis (Tervonen et al, 2010). On the other hand, acute toxicity tests have reported that fullerenes cause only minor or negligible effects to aquatic organisms (Tervonen et al, 2010;Pakarinen et al, 2011;Fraser et al, 2011;Petersen and Henry, 2012). There is a lack of conclusive data on chronic exposures; some evidence on benthic invertebrates has been reported (Waissi-Leinonen et al, 2012;Pakarinen et al, 2011;Oberholster et al, 2011) and even fewer studies of chronic toxicity to water flea D. magna (Tao et al, 2009).…”
