ISO 15202-3:2004规定了使用电感耦合等离子体原子发射光谱法分析按照ISO 15202-2规定从按照ISO 15202-1规定收集的空气颗粒物样品中制备的试验溶液的程序。规定了方法开发、性能检查和常规分析方法。
只要使用合适的分析波长,该程序不会受到明显的光谱干扰。然而,不准确的背景校正和/或不充分的矩阵匹配可能会对结果产生不利影响。
ISO 15202-3:2004适用于以下已设定限值的金属和类金属的非排他性清单:;然而,没有关于ISO 15202中规定的任何样品溶解方法有效性的信息-
2对于斜体字的元素:
铝、锑、砷、钡、铍、铋、硼、铯、镉、钙、铬、钴、铜、铪、铟、铁、铅、锂、镁、锰、汞、钼、镍、磷、铂、钾、铑、硒、银、钠、锶、钽、碲、铊、锡、钛、钨、铀、,钒、钇、锌和锆。
ISO 15202-3:2004不适用于单质汞的测定,因为未使用ISO 15202-1规定的取样方法收集汞蒸气。
所得结果可用于评估工作场所暴露于金属和类金属的情况,以便与限值进行比较。
ISO 15202-3:2004 prescribes a procedure for the use of inductively coupled plasma atomic emission spectrometry for analysing test solutions prepared as prescribed in ISO 15202-2 from samples of airborne particulate matter collected as prescribed in ISO 15202-1. Method development, performance checks and a routine analysis method are prescribed.
The procedure suffers from no significant spectral interferences, provided that suitable analytical wavelengths are used. However, inaccurate background correction and/or inadequate matrix-matching can adversely affect results.
ISO 15202-3:2004 is applicable to the following non-exclusive list of metals and metalloids for which limit values have been set; however, there is no information available on the effectiveness of any of the sample dissolution methods specified in ISO 15202-2 for those elements in italics:
aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, caesium, cadmium, calcium, chromium, cobalt, copper, hafnium, indium, iron, lead, lithium, magnesium, manganese, mercury, molybdenum, nickel, phosphorus, platinum, potassium, rhodium, selenium, silver, sodium, strontium, tantalum, tellurium, thallium, tin, titanium, tungsten, uranium, vanadium, yttrium, zinc and zirconium.
ISO 15202-3:2004 is not applicable to determination of elemental mercury, since mercury vapour is not collected using the sampling method specified in ISO 15202-1.
The results obtained may be used for the assessment of workplace exposure to metals and metalloids for comparison with limit values.
