W materiale polimerowym stosowanym jako separator elektrod w akumulatorze kwasowo-ołowiowym oznaczano zawartość kadmu, ołowiu i rtęci. W kontekście obowiązujących przepisów dotyczących wprowadzanych do obrotu baterii i akumulatorów oraz przetwarzania zużytych baterii i zużytych akumulatorów porównano wyniki badania próbek separatora przed użyciem w procesach elektrochemicznych oraz próbek odpadowych. W badaniach separatora [poprzedzonych analizą jakościową tworzywa metodami: skaningowej mikroskopii elektronowej/spektrometrii dyspersji energii promieniowania rentgenowskiego (SEM/EDS) i spektroskopii w podczerwieni z transformacją Fouriera (FT-IR)] wykorzystano nowoczesny aparat do mikrofalowego roztwarzania próbek w połączeniu z techniką absorpcyjnej spektrometrii atomowej z atomizacją w płomieniu (FAAS) i analizatorem rtęci. Zastosowane procedury analityczne weryfikowano na podstawie wyników badania certyfikowanego materiału odniesienia (PE-LD) zawierającego śladowe ilości analitów.

Results of cadmium, lead and mercury determination in the polymeric material used as an electrode separator in the lead-acid battery have been presented. Samples of the separator before use in the electrochemical processes and the waste separator samples have been compared with reference to the existing laws on batteries and accumulators and waste batteries and accumulators. In the polymer separator examination [preceded by a qualitative analysis of the material using scanning electron microscopy/ energy dispersive X-ray spectrometry (SEM/EDS) and Fourier transform infrared spectroscopy (FT-IR) techniques], a modern UltraWAVE digestion system combined with flame atomic absorption spectrometry (FAAS) technique and a DMA-80 Direct Mercury Analyzer has been used. The quality of metal determination results has been evaluated using a certified PE-LD reference material containing trace amounts of analytes.

W artykule scharakteryzowano metodę absorpcyjnej spektrometrii atomowej wykorzystującą automatyczny analizator rtęci AMA 254 jako jedną z technik pomiarowych zawartości rtęci. Zwrócono szczególną uwagę na zasadę działania analizatora rtęci AMA 254, jego precyzję oraz granicę oznaczalności stosowanego urządzenia. Dokonano szereg pomiarów materiału odniesienia, zwalidowano metodę, a następnie oznaczono zawartość rtęci w wielu surowcach stosowanych w przemyśle budowlanym. Porównano otrzymane wyniki z obowiązującymi aktami prawnymi oraz z danymi dostępnymi w literaturze.

The article describes the method of atomic absorption spectrometry using an automatic mercury analyzer AMA 254 as one of the techniques of measuring the mercury content. Special attention is paid to the mercury analyzer AMA 254 principle of operation, its precision, and the analyzer limits of quantification. There have been a series of the reference material measurements, Methods was validated. Then many raw materials and products used in the construction industry was analyzed for mercury content. We compared these results with the prevailing laws and the data available in the literature.

Comparison studies have been performed on determination of total mercury in wet deposition by two analytical methods. The studies were carried out in the period of March to November 2009 at the sampling point located near intensive traffic in Southern Poland (Zabrze). The difference between these two methods consisted in preparation of samples for analysis and in the type of measuring device. In both cases, the method of cold vapour atomic absorption spectrometry (CV-AAS) after reduction of SnCl2 was used by means of a mercury analyzer model MA-2 produced by Nippon Instruments Corp. or of a mercury analyzer RA-915+ produced by LUMEX. Good agreement of the results have been obtained (relative error of the determination between the methods varied from 18% to 40%). Both analytical methods can be considered equivalent and used as a reference to each other. Quantity assessment of mercury wet deposition in southern Poland is lower than in 90 s, but still much higher in comparison with other countries in Europe and worldwide (ca. 30 μg·m -2·year -1.

Intensive research has been carried out to measure and explain the presence, distribution and incredible accumulation ability of several metals in edible mushrooms. Mushrooms in contrast to green plants can store large amounts of particular trace elements. Special attention has been drawn to assess possible danger to human health connected with mushroom consumption. The distribution of Cd, Se and Hg was investigated in edible mushrooms collected from forest sites situated in the Lodz region. The quantitative analysis of metals was carried out by the flame atomic absorption spectrometry technique with the exception of Hg, which was determined by a mercury analyzer.

Determination of trace elements in combusted materials has always been an interesting field of environmental studies. Particulate matter, in particular, is a serious problem which, can lead to air pollution especially by heavy metals emissions in urban and industrial areas. There is a considerable concern about the elevated level of mercury released during combustion and the proportion of anthropogenic mercury in the environment. Nowadays, small-scale installations have been identified as a significant source-pathway for mercury pollution, particularly those that use coal. A total amount of mercury was determined using Mercury Analyzer. The investigated material consists of bottom ash, fly ash, slag, soot or dust. The obtained results varied according to the type of the material and plant. The developed methodology was checked by carrying out the analysis of certificate material of Soil NCS ZC 73001 and the reference material of Soil-7.
