CHEMICAL-ANALYSIS OF RAIN AND SNOW SAMPLES FROM CHERNOGOLOVKA RUSSIA BY IC, TXRF AND ICP-MS/

Data are reported for a first measurement campaign for a great number of cations (the range of concentrations for main components is given i n ng/mL: Na: < 70-880; Mg: 12-160; Al: < 7-120; K: 200-1600; NH4+: 250 0-9000; Ca: 300-2500; Fe: < 140-1200; Zn: 20-320) and anions (HCOO-: 1 00-1800; CH3COO-: 400-14500; C2O42-: < 100-460; NO2-: < 20-55; NO3-: 6 60-9900; SO32-: < 100-1150; SO42-: 450-19700; Cl-: 170-3200) in rain a nd snow samples of the Chernogolovka region 80 km northeast of the cen tre of Moscow. These data serve as a first assessment of the situation of the atmosphere in this region. For the determination of fluoride, formate, acetate, nitrite, bromide, nitrate, sulfite, and sulfate by I C, a relevant development of the method was carried out. For some meta llic cations, a critical quality control was achieved by parallel meas urements with ICP-MS, TXRF, and IC. Furthermore, time resolved measure ments were performed for a rain event. Filtration experiments were und ertaken to differentiate between the presence of a series of elements and species in liquid or solid state in the collected aqueous samples.
