  The presence of possible blends in the spectral region of the Li resonance
line at 6708 A in solar-type metal-rich stars is investigated using high
resolution and high signal-to-noise spectroscopic observations. Our analysis
does not confirm the identification of a weak absorption feature at 6708.025 A
with the low excitation TiI line proposed by Reddy et al. (2002). Our spectrum
synthesis suggests that the unidentified absorption is most probably produced
by a high excitation SiI line originally proposed by Muller et al. (1975).
Reanalysis of the Lithium-6/Lithium-7 isotopic ratio in HD82943 was performed
by taking the SiI line into account and using new VLT/UVES spectra of HD82943
with a signal-to-noise ratio close to 1000. We confirm the presence of
Lithium-6 in the star's atmosphere while the updated value for the isotopic
ratio is f(Lithium-6) = 0.05+-0.02.
