Elemental Monitoring Of Rainwater Samples By Inductively Coupled Plasma Mass Spectrometry, Antalya, Türkiye, 11 - 14 Mart 2020, ss.190
Trace elements become a part of biogeochemical cycles in the atmosphere after being introduced into the environment by natural and anthropogenic sources.1 After atmospheric deposition and recycling in the environment globally, these elements are deposited by rain, snow, dry fallout, and over 80% of wet deposited trace metals are dissolved in rainwater, reaching the vegetation canopy at the end.2 Therefore, studies of the occurrence and determination of heavy metals in ground, surface or harvested rain waters is an important issue for the human health and environment.3 In international monitoring programs also, measurement of heavy metals in wet deposition is becoming an increasingly central role in the production of basic data.4
Rainwater samples were collected from the terrace of EGE-MATAL for 24 hours at different times in the same season from 2017 to 2018 in the Izmir city center/Turkey. Up to 20 elemental levels in acidified 56 samples were determined without digestion by an Elan 9000 ICP-MS composed of a Ryton cross-flow nebulizer coupled to a Scott-type double-pass spray chamber, standard glass torch and nickel sampler/skimmer cones. Recovery studies and three certified water samples were used for validation purposes. Interference possibilities were assessed by isotopic analysis.
