Ocena Udziału Huty Katowice W Poziomie Opadu Pyłu, Ołowiu I Kadmu Na Powierzchnię Terenu Wokół Zakładu, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the results of modeling of deposition on the land surface of dust, lead and cadmium emitted from the "Katowice" Steelworks. The calculations were carried out in the vicinity of the location of the dust deposition measuring points existing around the plant. Computational data were compared with the results obtained from direct measurements for the same calendar year. The responsibility of this plant in shaping the level of dust and heavy metal deposition in the region of the protective zone was determined.

English title: Participation of the "Katowice" Steelworks in the level of dust, lead and cadmium deposition …

Air Sampling With Solid Phase Microextraction, Jacek A. Koziel, Fabio Augusto, Janusz Pawliszyn

Jacek A. Koziel

Solid phase microextraction (SPME) presents many advantages over conventional analytical methods by combining sampling, pre-concentration and direct transfer of the VOCs into a standard gas chromatography (GC) system. Since its introduction SPME has been applied to the sampling and analysis of environmental samples including airborne VOCs and particulates. The first part of this paper presents theory of air sampling with SPME and an overview of the a few current methods for quantitative air sampling and VOC determination with SPME using grab (‘instantaneous”) and time-weighted average (TWA) modes. The second part of this paper is focused on the recent development of …
