    Lead Content in Edible Wild Mushrooms in Northwest Spain as Indicator of Environmental Contamination (1998)
    Springer
    Archives of environmental contamination and toxicology 34 (1998), S. 330-335 
    Details
    ISSN: 1432-0703
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering , Medicine
    Notes: Abstract. Lead content was determined in wild growing mushrooms collected from two different areas in the Province of Lugo (NW Spain). It has been analyzed by graphite furnace atomic absorption spectrometry in 95 samples of 13 species (7 mycorrhizals and 6 saprophites). In an assessment of lead concentrations, the following factors have been considered: species and ecology, morphological portion, and traffic pollution. The average lead concentration of the samples was 1 ppm dry weight (dw). Saprophite species presented higher levels than mycorrhizal ones (〈1 ppm), Coprinus comatus reaching the maximum mean concentration with 2.06 and 2.79 ppm of dw in the hymenophore and the rest of the fruit body. Morphological portion, statistically, did not show significant difference between the two portions; however, Macrolepiota procera always presented lead high levels in the hymenophore in all samples. The effect due to traffic pollution has been specially observed in Coprinus comatus, presenting the highest concentration with values of 6.51 and 10.43 ppm, respectively, in samples collected in the city center. This species, as other researchers have indicated, could be considered as an indicator by lead contamination. The contribution of mushrooms to the weekly intake of lead was calculated and the posible health risk for the consumer is pointed out. These data are of great importance in view of toxicology and partly environmental protection.

    Metabolism and Cytotoxicity of Chlorpropham (CIPC) and Its Essential Metabolites in Isolated Rat Hepatocytes During a Partial Inhibition of Sulphation and Glucuronidation Reactions: A Comparative Study (1998)
    Springer
    Archives of environmental contamination and toxicology 35 (1998), S. 89-96 
    Details
    ISSN: 1432-0703

    Notes: Abstract. The changes in metabolism and cytotoxicity of chlorpropham (CIPC) and its major metabolites, 4-hydroxychlorpropham (4-OH CIPC), 3-chloroaniline, and 3-chloroacetanilide were investigated in isolated rat hepatocyte suspensions after a partial inhibition of sulphation and glucuronidation and the two reactions combined in an attempt to assess the part of each of them in the enhanced CIPC toxicity observed in vivo after D-galactosamine treatment. With sulphation and glucuronidation effective, CIPC has a cytolytic effect and reduces intracellular ATP and K+ level while 4-OH CIPC has a weak cytolytic effect but modifies ATP and K+ level in a greater extent than CIPC. Inhibition of sulphation does not affect the cytotoxicity of CIPC or 4-OH CIPC because there is a compensatory increase in the amount of 4-OH CIPC glucuronide formed and the level of free 4-OH CIPC always remain low. In contrast, when incubations are carried out with either CIPC or 4-OH CIPC, the presence of D-galactosamine leads to a decrease of glucuronide and sulphate conjugates accompanied, respectively, by a 3.6-fold and 6.9-fold increase of the free 4-OH CIPC level in the culture medium. This alteration of the metabolism is followed by a marked reduction of ATP synthesis with a concomitant modification of cell permeability. The cytolytic effect is due to CIPC itself, whereas the effect on energy supply was attributed to free 4-OH CIPC. The results demonstrate a combined effect of free 4-OH CIPC and D-galactosamine on intracellular ATP level that could account for the partial inhibition of sulphation. This change in the CIPC metabolism could explain the increased CIPC toxicity observed in vivo after D-galactosamine pretreatment.

    Accumulation of Mercury in Edible Macrofungi: Influence of Some Factors (2000)
    Springer
    Archives of environmental contamination and toxicology 38 (2000), S. 158-162 
    Details
    ISSN: 1432-0703

    Topics: Energy, Environment Protection, Nuclear Power Engineering , Medicine
    Notes: Abstract. The levels of mercury in terrestrial ecosystems are generally very low, but the strong accumulation in some species of macrofungi is an exception from this rule. Mercury contents of 41 samples of edible mushrooms fruiting bodies representing eight species (six wild and two cultivated) were determined by an anodic stripping voltammetric technique (ASV) using a gold disc as the working electrode. Wild fungi were collected in unpolluted and polluted areas in the Province of Lugo (NW Spain). Influence of some factors (ecology, species, traffic pollution, and morphological portion) and the importance of mushrooms as a dietary source of mercury have been studied. Wild saprophytic species showed higher levels (ppm DW) than mycorrhizals species, with the exception of Boletus pinicola. There were significant differences according to the species analyzed (p 〈 0.001), the highest average content of mercury was found in Boletus pinicola (7.37 ppm DW), and the range was 0.35–33.07 ppm DW for hymenophore and 0.18–20.30 ppm DW for the rest of the fruit body. The cultivated species accumulated lower than wild species because the mean life is shorter. The traffic pollution factor did not show significant differences, so mushrooms are not realiable bioindicators of traffic pollution by mercury. Hymenophore was always the morphological portion that contained the highest mercury levels (p 〈 0.05), and the mean ratio of hymenophore/rest of the fruit body was 2.13. The mercury concentrations were compared to literature data and levels set by legislation, and the contribution of mushrooms to the weekly intake of mercury per person was evaluated. The possible health risk for people is pointed out.

    Notes: Abstract We investigated the effects of urban drainage on thewater quality of springs feeding drinking waterfountains in Lugo, a city in northwest Spain. Theparameters determined were electrical conductivity,dry residue, pH, dissolved O2, NO3 -,NO2 -, NH4 +, Cl-, organicmatter, turbidity, colour, Fe, Mn, Cu and Zn. The datawere analysed with the aid of principal componentsanalysis and cluster analysis. The first two axesextracted by principal components analysis of thesamples-by-variables matrix represented (a) salinecontamination, strongly influenced by degree ofdilution, and (b) organometallic contamination,strongly influenced by redox conditions.Within-location temporal variation in water qualitywas probably largely due to seasonal variation inrainfall amounts.
