Combined XRF and integrated SAXS experimental results. (a) Scatter intensity map of a scanned algae based on the number of illuminated pixels from each scattering pattern (0.2 s exposure per point). (b) Algae isolated from (a) using μ + σ as a threshold. (c) Cell isolated from the integrated SAXS map based on (b). (d) Mn, (e) Fe and (f) Zn distribution maps of a scanned Ni-exposed algae with an indication of the accumulation centre (50 µg l−1 Ni, 48 h exposure). |
