Occurrence of Li in groundwaters and plants from Dobrogea karst area, Romania

A positive association of Li consumption with the potentially protective and beneficial for human health was reported (Barjasteh-Askari et al. 2020). Drinking water, grains, or vegetables can be a significant source humans. Microdoses intake may have antisuicidal, mood-stabilizing, antidepressive, antimanic effects (Knudsen 2017; Ng 2019). The assessment naturally occurring concentrations in water food sources different regions present high interest wellbeing locals. In this study, versatile quantitative ICP-MS method determination plant samples optimized, relationship between Li, macroelements (Na, Mg, Al, K, Ca, Fe, Mn), microelements (Cr, Co, Ni, Cu, Zn, Pb, Sr, Ba, V, As, Cd, Pb) concentration assessed. Contents micro- were measured groundwater (Praporgescu-GWR27, Closca-GWR28, Sipote-GWR29, Tufani-GWR30) (ryegrass—Lolium sp., nettles—Urtica mint—Mentha sp.) collected from Dobrogea karst area, Romania. results indicated an acceptable precision all studied matrixes reproducibility 2.46 4.22% developed method. case highest GWR27 followed by GWR28 (12.2 5.6 µg/L), while plant’s samples, Lolium sp. (11.1 8.8 mg/kg DW) had concentration.
