Figure 7
The relationships between δ18Oc(VSMOW) and δ18Odw values are shown for individuals who had resided in Canada during tissue formation (n = 41). Colours indicate the MV or non-MV residence, and shapes indicate the type of drinking water sampled for its δ18Odw value. The different line types show the regression line between δ18Oc and δ18Otap values for Eq. (2): δ18Oc(VSMOW) = 0.11 (± 0.09) × δ18Otap(VSMOW) + 23.29 (± 0.98); [df = 32; \(\overline{R }\)2 = 0.01], δ18Odw values including both tap and surface water values for Eq. (3): δ18Oc(VSMOW) = 0.16 (± 0.08) × δ18Odw_1(VSMOW) + 23.77 (± 0.82); [df = 35; \(\overline{R }\)2 = 0.09] and δ18Odw values for all samples for Eq. (4): δ18Oc(VSMOW) = 0.15 (± 0.07) × δ18Odw_2(VSMOW) + 23.65 (± 0.78); [df = 37; \(\overline{R }\)2 = 0.08].
