Abstract
- International audience; Surface waters from three catchments having contrasting land-uses (forested, agricultural, and urban) were sampled monthly and analysed for nanoparticulate titanium dioxide (NPs-TiO2) by single particle ICPMS and electron microscopy. We report one-year of data for NPs-TiO2 having average number and mass concentrations of 9.1 x 108 NPs-TiO2 particles L-1 and 11 μg NPs-TiO2 L-1 respectively. An increase in concentration during warmer months is observed in the forested and agricultural catchments. Both concentrations of NPs-TiO2 are within the range of recently reported values using similar analytical approaches. The positive correlations for NPs-TiO2 mass concentration or particle number with the concentration of some trace elements and DOC in the forested and agricultural catchments suggest the detected NPs-TiO2 in these two systems are mostly from geogenic origin. Additionally, microscopy imaging confirmed the presence of NPs in the three catchments. Furthermore, the land-area normalized annual flux of NPs-TiO2 (1.65 kg TiO2 year-1 km-2) was highest for the agricultural catchment, suggesting that agricultural practices have a different impact on the NPs-TiO2 dynamics and exports than other land-uses (urban or forestry). A similar trend is also found by the reanalysis of recent literature data.
