Workplace air - Determination of particulate lead and lead compounds - Flame and electrothermal atomic absorption spectrometric methods

This document specifies flame and electrothermal atomic absorption spectrometric methods for the determination of the time-weighted average mass concentration of particulate lead and lead compounds in workplace air.
These methods are typically applicable to personal sampling of the inhalable fraction of airborne particles, as defined in ISO 7708, and to static (area) sampling. It can be applied to other health-related fractions as required.
The sample dissolution procedure specifies hot plate or microwave assisted digestion, or ultrasonic extraction (see 11.2). The use of an alternative, more vigorous dissolution procedure is necessary when it is desired to extract lead from compounds present in the test atmosphere that are insoluble using the dissolution procedures described herein (see Clause 5).
The flame atomic absorption method is applicable to the determination of masses of approximately 1 µg to 200 µg of lead per sample, without dilution[1]. The electrothermal atomic absorption method is applicable to the determination of masses of approximately 0,01 µg to 0,5 µg of lead per sample, without dilution[1].
The ultrasonic extraction procedure has been validated for the determination of masses of approximately 20 µg to 100 µg of lead per sample, for laboratory-generated lead fume air filter samples[2].
The concentration range for lead in air for which this procedure is applicable is determined in part by the sampling procedure selected by the user (see 10.1).

Zrak na delovnem mestu - Določevanje svinca in svinčevih spojin v delcih - Plamenska in elektrotermijska atomska absorpcijska spektrometrijska metoda

Ta dokument določa plamenske in elektrotermijske atomske absorpcijske spektrometrijske metode za določanje časovno obtežene povprečne masne koncentracije svinca in svinčevih spojin v delcih v zraku na delovnem mestu.
Te metode se običajno uporabljajo za osebno vzorčenje inhalabilne frakcije delcev v zraku, kot je opredeljeno v standardu ISO 7708, in za statično vzorčenje (območja). Uporabljati jih je mogoče tudi za druge frakcije, povezane z zdravjem.
Postopek raztapljanja vzorcev določa razkroj s pomočjo grelne plošče ali mikrovalovne pečice oziroma ultrazvočno ekstrakcijo (glej točko 11.2). Uporaba alternativnega, močnejšega postopka raztapljanja je potrebna, kadar želimo izločiti svinec iz spojin, ki so prisotne v preskusni atmosferi, a jih ni mogoče raztopiti s tu opisanimi postopki raztapljanja (glej odstavek 5).
Plamenska atomska absorpcijska metoda se uporablja za določanje mas, ki brez redčenja znašajo približno od 1 µg do 200 µg svinca na vzorec[1]. Elektrotermijska atomska absorpcijska metoda se uporablja za določanje mas, ki brez redčenja znašajo približno od 0,01 µg do 0,5 µg svinca na vzorec[1].
Postopek ultrazvočne ekstrakcije je potrjen za določanje mas, ki brez redčenja znašajo približno od 20 µg do 100 µg svinca na vzorec, za vzorce zračnih filtrov za svinčene hlape[2].
Razpon koncentracije svinca v zraku, pri katerem se uporablja ta postopek, je delno določen s postopkom vzorčenja, ki ga izbere uporabnik (glej točko 10.1).
