Significant differences between the contaminated and uncontaminated implant groups were determined using Student's t-test for independent samples.
In the RDS, no differences were found between the contaminated and the reference site for any metal in the K. mollis specie (P > 0.05); however for the A. lechuguilla and J. dioica species differences were found (P < 0.05) (with the exception of Zn in A. lechuguilla and Pb in J. dioica).
Regarding the total diversity of the RDS (Table 3), a statistically significant difference was registered (P < 0.05), between the contaminated and the reference site.
The difference between radioactivity values of the contaminated untreated soil and the contaminated treated soil is 30,9 DPM/g, which corresponds to the total extracted radioactivity, and represents 35.6% of the initial radioactivity.
There was no statistically significant difference between survival of contaminated and uncontaminated operations when we analyzed THRs and TKRs together, with either revision for any reason or aseptic loosening as endpoint.
Differences between cycle threshold (Ct) values of purified RNA samples in presence and absence of RT were typically > 20, corresponding to a 40-fold difference between RNA over contaminating DNA concentration, confirming the quality of RNA isolates.
There was no statistical difference between the incidence of S. enterica contaminated tomato plants, rhizoplane or phyllosphere, with and without X.
For this work, the experiment showed no significant differences between control and contaminated organisms.
Indeed, differences between controls and contaminated treatments were mainly due to an overall reduction in densities of the most abundant species in contaminated treatments.
