4, it can be seen that EVAO
has almost no char residue and the char residue mass of other samples is higher than that of EVA0, especially for EVA5.
4.2 Comparing the risk values using the EVAO
Mean concentrations of plasma selenium measured at EVAO
were significantly higher in surviving individuals [mean (SD), 1.10 (0.20) [micro]mol/L [than in those who died [1.01 (0.20) [micro]mol/L; P <[10.sup.-4]].
7, it can be found that EVA1 shows lower decomposition rate in the second step but higher in the First step than EVAO
. The incorporation of LDH lowers the decomposition rate of the Second step but accelerates the loss of acetic acid.
