We observed, both in the leaves and roots of the vegetables examined, that the concentration of fluoride was in each case higher in vegetable samples in Łosień, 6 km from the “Katowice” Steel Works (fluorine emitters), than in the vegetable samples grown in Nowy Sącz, 200 km from the “Katowice” Steel Works (in the area of relatively low fluorine pollution). The highest F content was characteristic...
BCF1 (bioconcentration factor after the one day of exposition) value of BaP [benzo(a)pyrene] in strain A-8, Chlorella vulgaris Beijerinck 1890 (Chlorella BB) was studied. The algae were cultured in a modified Ku¨hl-Lorentzen liquid medium at room temperature, under continuous illumination and stirring for 24 hours. The final average value of BCF1 equalled 2100 ± 140 for BaP initial concentrations...
There was developed a little-work-consuming and non-expensive microdiffu- sion method of carboxyhaemoglobin determination in bloody in low range concentration. It can be used in the assessment of passive smokers' exposure to carbon monoxide. The amount of blood neccessary for the determination was 0.15 ml. An average precision of the developed method of the carbon monoxide determination (converting...
Stwierdzono uzależnione od gatunku papierosów, duże zróżnicowanie zawartości fenoli lotnych z parą wodną w Równym strumieniu dymu papierosowego, ich współwystępowanie w dymie tego samego gatunku papierosów w podobnych proporcjach oraz znaczną toksyczność dawek badanych fenoli pobieranych przez palaczy po wypaleniu 20 papierosów w ciągu doby.
This paper reports that selected low molecular hydrocarbons, i.e. hexane, cyclohexane and benzene added to cultures of the alga Scenedesmus obliquus (Chlorococcales), grown under auxotrophic and sterile conditions, inhibit the growth and stimulate the accumulation of cell wall carotenoids. The maternal cell walls contain: canthaxanthin, astaxanthin and its oxidation products, i.e. astacene and semiastacene,...
An inhibition of growth of Chlorella vulgaris, Beijerinck 1980 laboratory cultures carried out under different conditions caused by benzene, phenol and catechol was investigated. Each of the investigated substances was added to the culture medium at 4 or 5 different concentrations, directly before inoculation. The cultures were carried up to the stationary phase of growth. The density of alga cell...
Our objective was the assessment of algal medium harmfulness for in vitro fibroblasts. The algal medium was from Chlorella cultures (Beijerinck 1890) grown in the presence of benzene, which was added before the inoculation of culture. The medium contained, besides the benzene residues, its various metabolites formed during culture, among them phenol and catechol. Its addition to fibroblast cultures...
