eng	A practical approach to “greening” the multielemental analysis	In this work, main goal was sample downsizing, limiting of the pretreatment steps before ICP-OES/MS analysis and using a low-consumption sample introduction system, which resulted in considerations of: (i) salinity of digests, (ii) matrix effects (ME), and (iii) the environmental footprint of both methods. Possible downsizing of sample mass or final volume of digest is closely connected with the analytical performance of the ICP-OES/MS methods (limits of detection) and, on the other hand, with the degree of salinity of samples. Higher amount of total diluted salts allowed to be introduced to the ICP-OES (up to 30 % w/v, in the ICP-MS only 0.1% w/v) increases the ME risk. The ME was discussed as an effect of individual components or mixtures (Li, Na, K, Ca, Mg, Rb, Ba, La, and acids up to 20 g L-1) in connection with sample introduction system used. Using of the ICP-OES with the low-consumption introduction system resulted to a “nearly matrix-independent” method more environmentally friendly than the ICP-MS method analyzing the same downsized sample.
