The distribution of arsenic in the region of Katowice is described. In the sedimentation velocity of arsenic different related from distance of distribution in rainy period and sun period. For the given direction wind the surface load of suspended dust were investigated. The concentration of arsenic in air and in fallout changed in relation to wind velocity and inversion layer height.

The content of Cu, Pb, Zn, Fe, Cd and S in the upper soil layer of meadow ecosystems surrounding the steelworks "Huta Katowice" was investigated. Sampling plots were located at a different distance and direction from the plant, but in a similar type of meadow community and soil. Spatial and seasonal variability of the investigated elements content was found. Such results indicate that the investigated area was polluted both by that steelworks and by the industrial plants situated in the Industrial Region of Upper Silesia.

This paper presents results of a study on determination of the concentration of Cd, Pb, Cu and Zn in neoplastic and peri-neoplastic lung tissues from 110 subjects of two regions of different degrees of environmental pollution: Wielkopolska (75) and Upper Silesian Industrial District (35). The concentrations of the metals were determined by the method of differential pulse anodic stripping voltammetry (DPASV). The mean values (in mug/g wet tissue) obtained for the inhabitants from Wielkopolska were: Cd - 0.56; Pb - 0.45; Cu - 1.98; Zn - 12.93 in the neoplastic tissue and Cd - 0.88; Pb - 0.40; Cu - 1.96; Zn - 12.80 in the peri-neoplastic tissue. For the inhabitants from the Upper Silesian Industrial District (USID) the corresponding values were: Cd - 0.63; Pb - 0.25; Cu - 1.61; Zn - 20.63 in the neoplastic tissue and Cd - 1.37; Pb - 0.06; Cu - 1.66; Zn - 19.20 in the peri-neoplastic tissue. Concentrations of Cd were higher in peri-neoplastic tissues than in the neoplastic ones in the subjects from both groups. The highest concentrations of Pb and Cu were found in tissues of the inhabitants from Wielkopolska, while the highest concentrations of Cd and Zn were in tissues of those from Upper Silesian Industrial District.

Lead, cadmium, zinc, manganese, chromium, cobalt, copper, and molybdenum concentrations were measured in 50 samples of placenta tissues. The samples came from Tychy in the Upper Silesian Industrial District (Poland), where the population is exposed to enormously increased levels of heavy metals. GFAAS technique was used. Various methods of ashing samples were examined. Wet ashing under pressure in the teflon bomb at 110°C with HNO, and wet ashing under normal pressure with HN03 + H202 are considered to be the best ones. Mean concentrations of metals in the placenta were determined. Coexistence of increased levels of various metals was checked. Concentration of heavy metals in the samples coming from the polluted industrial territory is higher than in those collected in cleaner regions.

W pracy przedstawiono wyniki badań dotyczące częstotliwości występowania na strzałach l'mus nigra raków drzewnych, których powstawanie przypisano Crumenulopsis sororia. Podano wymiary drzew porażonych w porównaniu z drzewami nie porażonymi oraz przeprowadzono wielostronny analizę miejsc rozwoju raków na strzałach.

The study was carried out in 1990 in the experimental area in Pniowiec, situated in the Świerklaniec forest management unit. The area was established in 1973 in 90-year-old Scotch pine stand growing in fresh coniferous forest site in zone of moderate pollution with industrial emissions. The purpose of establishing this area was to study I he growth, development and survival of trees planted under the various variants of convert inn of old stand. The results оf the analysis of Hie occurrence of tree cancers caused by Crumenulopsis sororia on stems of" living trees of Pinus nigra (2315 trees on 24 experimental plots) are presented in this paper. The cancers were found on 1267 (54,7%) trees. Most often they were present on trees planted on the streep clear cut area. On a single stem there were one to eight places where the cancer has developed. Out of 2161 cancers found most (65,0%) were in the initial stage of development. Taking all experimental plots into consideration 76,5% of cancers developed on stems in vicinity of whorls. The cancers were situated on all sides of the stem, but most often they were formed on northern side Above all they were formed in the basal part of a tree. Trees taller and of higher diameter were attacked a little more frequently

Badano narażenie na tlenek węgla wybranych grup ludności związane z zamieszkiwaniem terenów uprzemysłowionych i paleniem papierosów. Badaniami objęto grupy osób nienarażonych, narażonych środowiskowo i niepalących, nienarażonych środowiskowo palaczy papierosów. Wskaźnikiem narażenia było stężenie HbCO we krwi. Określono udział poszczególnych źródeł w narażeniu mieszanym na tlenek węgla.

The aim of the work was an estimation of the effect of smoking on environmental exposure to CO people living in industrial area of Sosnowiec (a city situated in Upper Silesia) and Tomaszów Lubelski (not much industrially town situated at the border of Roztocze National Park). The investigated material was vein blood of 102 blood donors from Sosnowiec and 103 blood donors from Tomaszów Lubelski both smokers and non-smokers. The level of CO exposure was estimated by determination of carbon monoxide haemoglobin (HbCO) concentration in blood by Wolfs method in Antczak's adaptation. It was stated that average HbCO concentration at non-smokers from Sosnowiec (2,09%) was about 0,9% higher than the one at non-smokers from Tomaszów Lubelski (1,17%). An increase of HbCO concentration in blood of non-smokers from Sosnowiec as compared with non-smokers from Tomaszów Lubelski included also 50 and 90 percentile. In relation to 50 percentile it was 2,05 and 1,0% and in relation to 90 percentile 2,4 and 3,7% respectively. The influence of external environment on CO exposure at smokers was estimated on the base of HbCO determination in blood before starting smoking. It was 2,77 at smokers from Sosnowiec and 1,41% at smokers from Tomaszów Lubelski. Analysing the effect of smoking on smokers exposure to CO it was stated that HbCO concentration in blood in both groups increased linearly with the increase of the number of smoked cigarettes, and average increase per one cigarette was 0,43% for smokers from Sosnowiec and 0,57% for smokers from Tomaszów Lubelski. On the base of the obtained results the following conclusions were drawn: 1. industrial and communal environment contamination with carbon monoxide influences considerably the exposure of both smokers and non-smokers. 2. smoking effects significantly more the exposure of people (smokers) to carbon monoxide than environmental pollution in the investigated industrial area. 3. the exposure to carbon monoxide at smokers up with the environmental exposure.
