Fig 3. a-b: Bar graphs with element weight fractions within entire neutrophils throughout PMA stimulation for the elements P, S, K, Cl, K, Ca, Mn, Fe, Co (upper graph, Fig 3a) and for Ni, Cu, Zn, Se, Br, Sr and Pb (lower graph, Fig 3b).

Fig 3

Neutrophils from control culture are indicated in green, 1 h PMA-stimulated neutrophils in blue and 2 h PMA-stimulated neutrophils in red. Weight fractions are expressed in %, ppm or ppb in a (different) logarithmic scale. Weight fraction values are normalized to the Compton intensity of neutrophil “0h_donorA_ cell1”. Error bars are based upon Poisson counting statistics and the certified uncertainty values of NIST SRM1577C “Bovine liver”.
