Water chemistry of seven lakes in Belarus and Ukraine 2014 to 2016

    Dataset

    Description

    Data comprise water chemistry measurements (major alkali and alkali-earth element water concentrations and trace element concentrations) recorded over two years at seven lakes in Belarus and Ukraine at distances from 1.5 to 225 km of the Chernobyl Nuclear Power Plant (CNPP). The lakes include Glubokoye, Yanovsky lakes and Cooling Pond (high (H) contaminated lakes), Svyatoye Lake (medium (M) contaminated lake) and Stoyacheye, Dvoriche and Gorova lakes (low (L) contaminated lakes).,After filtration on a 0.2 micrometre mesh size filter and acidification (2% v/v of HNO3 65% trace metal grade, Sigma), major alkali and alkali-earth element water concentrations (Na, Mg, S, K and Ca in mg/L, mean ± SD, n = 3 per lake) and trace elements concentrations (As, Sr, Cd, Cs, Pb and U in micro g/L, mean +/- SD, n = 3 per lake) were measured in the 7 lakes with quadrupole-based ICP-MS system (Model iCAPQ; Thermo Scientific) equipped with CCTED, ‘collision cell mode’ (7% Hydrogen in Helium) with kinetic energy discrimination (KED) to eliminate polyatomic interferences. Samples entered the ICP-QMS through an auto-sampler (Cetac ASX-520) via a nebuliser (Thermo-Fisher Scientific; 1mL min-1) and spray chamber. Internal standards were introduced to the sample stream via a separate line including Ge (50 micro g/L), Rh (20 micro g/L) and Ir (10 micro g/L) in 2% HNO3. Two sets of external mulit-element calibration standards for major elements (0-30 mg/L) and trace elements (0-100 micrograms per litre) were prepared from Certiprep(TM) multi-element stock solutions. After filtration on a 0.45 micrometre mesh size filter and preservation (1% v/v of ZnCl2 50% w/v), concentrations of inorganic macronutrients (NO3-, NO2- and PO43- in μg/L, mean +/- SD, n = 3 per lake) were determined using a QuAAtro segmented flow nutrient analyser with autosampler (SEAL Analytical, UK). Analysis was done according to standard procedures.,
