BACKGROUND: Although the maternal fish consumption is supposed to have beneficial effects on development of infants, it may be harmful for child cognitive development since fish is a common source of methylmercury. PURPOSE OF THE STUDY: Purpose of the study was to describe the usual pattern of fish consumption during pregnancy in Poland and explain the variability of prenatal mercury exposure due to fish intake by mothers. The other endpoint of the study was the assessment of the cognitive and psychomotor development of infants related to prenatal mercury exposure over the 3-year follow-up. MATERIAL AND METHODS: The study sample consisted of 374 infants born at 33-42 weeks of gestation between January 2001 and March 2003 to mothers attending ambulatory prenatal clinics in the first and second trimesters of pregnancy. Total mercury level in whole cord blood was measured and the Bayley Scales of Infant Development (BSID-II) was used to assess the mental (MDI) and psychomotor developmental index (PDI) in children at 12, 24 and 36 months of age. RESULTS: Self-reported weekly amount of fish consumption during the first two trimesters of pregnancy correlated positively with umbilical cord mercury concentrations (r(s)=0.22, p<0.0001). The corresponding correlation coefficient for the fish consumption in the third trimester of pregnancy was 0.21, p<0.0001. There was an inverse association between mercury exposure and both MDI (beta regression coeff.=-2.8, p=0.01) and PDI scores (beta coeff.=-2.3, p=0.04) at 12 months of age. Subsequent BSID-II testing at 24 and 36 months did not confirm significant association between exposure and cognitive or psychomotor function. The estimates of association between mercury prenatal exposure and the development of infants, which were based on the longitudinal analysis of all BSID-II measurements done in the follow-up (generalized estimating equations statistical model) showed that the performance deficit observed at 12 months of age was of border significance. 相似文献

The article presents the results of screening research on acute toxicity of groundwater contaminated by leachates to the bacterium Vibrio fischeri (ToxAlert 100® test) and crustacean Daphnia magna (Daphtoxkit F? magna test according to PN-EN ISO 6341), as well as on chronic toxicity to D. magna (test according to ISO 10706). The groundwater samples were taken from seven large city landfills in the Pomeranian province (Poland), which were open before 1990 and designed without proper attention to being leak-tight. Due to the lack of either European or Polish classification of ecotoxicological qualities of surface and underground waters, an attempt was made to evaluate the ecotoxicological quality of the examined waters on the basis of the Helsinki Committee's recommendations for industrial effluents, the classification of sediment according to Krebs (Krebs F. The pT-value as a classification index in aquatic toxicology. GIT Edition Umweltanalytik-Umweltschutz 1988;1:57–63) and the classification system of toxicity levels for natural waters and sewers, recently proposed by Persoone et al. (Persoone G, Marsalek B, Blinova, I, Törökne A, Zarina D, Manusadzianas L, Nalecz-Jawecki G, Tofan L, Stepanova N, Tothova L, Kolar B.

The growing interest of citizens in environmental issues is reflected in the mission statements and actions of non-governmental organisations (NGOs), defined as bodies that are voluntary, non-profit and independent of public authority. The article analyses the activities of Polish NGOs with regard to the environmental dimension of sustainable development. The overarching research question posed in this article refers to the extent to which entities of the third sector adopt, implement and appropriately report the implementation of the principles of sustainable development. The empirical basis for the analysis has been found in the statements made by public benefit organisations, as well as in data concerning the activities of NGOs from publications covering the concept of sustainable development. 相似文献

The aim of this study was to compare recoveries of organochlorine pesticides (heptachlor, α-HCH, β-HCH, γ-HCH, op'-DDD, pp'-DDD, pp'-DDE, op'-DDT, pp'-DDT) from fish muscle dried by two alternative methods: (i) grinding with anhydrous sodium sulphate and (ii) freeze drying. Pesticide residues content was determined by gas chromatography-mass spectrometry (GS-MS) method. For four pesticides (γ-HCH, α-HCH, heptachlor and pp;-DDD) in four of five fish species, higher recoveries were obtained from the freeze-dried samples. For five remaining pesticides, correlations between fish species and drying method were not found. The results of this study do not clearly indicate which drying method caused lower losses of analytes. Recoveries from the freeze-dried samples ranged from 69.9 to 117.6 %, while recoveries from the samples ground with sodium sulphate varied from 64.4 to 126.7 %. Either of the methods gave satisfactory recoveries and they both can be used interchangeably. 相似文献

Obsolete pesticides were stored in Poland from the middle sixties until the late eighties of the 20th century mostly in underground disposal sites, called "pesticide burial grounds" or "pesticide tombs". The total amount of pesticide waste and packaging materials disposed of in these landfills exceeded 20000 Mg. Typically, the content of a pesticide tomb was dominated by organochlorine pesticides (comprising 10-100% of the total waste volume) with DDT as the prevailing compound. Other pesticide types, such as phosphoroorganic, carbamate insecticides, dinitrophenols, phenoxyacids, and inorganic compounds were stored in smaller quantities, usually not exceeding 10-20% of the total waste volume. With the growing awareness of the threats that these landfills posed to the environment, the first inventory for the whole country was made in 1993 and remediation was initiated in 1999. The total amount of waste, which had to be removed from the known pesticide tombs (hazardous substances, contaminated soils, construction materials etc.) was about 100000 Mg. According to the National Waste Management Plan, the reclamation of pesticide tombs was assumed to have been finished by the end of 2010, however, this goal has not been achieved. The aim of this review is to present a historical perspective of pesticide burial grounds in Poland with an emphasis on their creation, function, inventory, and remediation. Based on unpublished reports, and other published materials of limited availability written in Polish, this review may serve as a source of information for representatives of other countries, where remediation of pesticide burial grounds is still in progress. The experience gained over a ten-year period, when restoration of pesticide tombs was implemented in Poland, reveals that there are many obstacles to this action arising not only from technical, but also from economic and social issues. 相似文献

Monitoring of the total content of polycyclic aromatic hydrocarbons (PAHs) in arable soils in Poland 总被引:9,自引:0,他引:9
The paper provides comprehensive information on the level of contamination of arable soils in Poland with polycyclic aromatic hydrocarbons (PAHs). Extensive monitoring studies were carried out to determine the content of the 16 priority PAHs in 216 soil samples collected in 2005 throughout arable lands (0-20 cm layer) in Poland. Locations of sampling points reflected the differences in regional industrialisation and urbanisation as well as in the characteristics of soils. The content of Sigma16PAHs ranged from 80 to 7264 microg kg(-1) with a median of 395 microg kg(-1) and with a dominance of 4-6 rings hydrocarbons (74% of total PAHs). Soil properties affected the PAHs content to a limited extend. The organic matter content was the only parameter correlated significantly (although weakly) with the concentrations of Sigma16PAHs; the strength of this relationship was more pronounced in soils with elevated OM content. The various molecular markers pointed to a prevailing pyrogenic origin of the PAHs in Polish arable soils, with minor contribution from liquid fuels combustion and traffic emissions. Two different Polish systems for classification of agricultural soils (providing for the content of Sigma9PAHs and Sigma13PAHs) indicate that the percentage of contaminated arable soils in Poland does not exceed 10%. Multivariate methods enabled an evaluation of spatial trends in Sigma16PAHs concentrations, an identification of regions with very low PAHs content (East part of the country), and a recognition of small industrial/urbanised areas of higher risk. 相似文献

Twenty samples of the moss species Hylocomium splendens and Pleurozium schreberi were collected at 10 sites of the Holy Cross Mountains (south-central Poland) and analyzed for 16 polycyclic aromatic hydrocarbons and 33 elements. The ring sequence of PAHs in the moss samples is: 4 (92-1040 ng x g(-1))>3 and 5 (21-272 ng x g(-1))>6 (<5-131 ng x g(-1)). H. splendens accumulates PAHs more effectively than P. schreberi, and therefore the former may be regarded as a better bioindicator of PAHs. No correlation was found between concentrations of PAHs and elements. However, both H. splendens and P. schreberi shows different bioaccumulative capabilities depending on the plant communities. The mosses growing in the dry pine forest Cladonio-Pinetum reveal higher levels of Fe, Na, Sr, Ti, Cr, Mo, Ni, V and higher mean concentrations of summation operator16 PAHs, whereas those from the continental coniferous forest Querco roboris-Pinetum are highlighted by elevated levels of B, Ca, K, Mg, Mn, P, Rb and Sb and lower mean concentrations of summation operator16 PAHs. These differences seem to be brought about by a higher biodiversity of the second forest type and its higher productivity that favors more effective cycling of elements. 相似文献

Protected areas due to their long-term protection are expected to be characterized by good water quality. However, in catchments where arable fields dominate, the impact of agriculture on water pollution is still problematic. In Poland, recently, the fertilization level has decreased, mostly for economic reasons. However, this applies primarily to phosphorus and potassium. In order to evaluate the impact of agriculture on water quality in a protected area with a high proportion of arable fields in the aspect of level and type of fertilization, complex monitoring has been applied. The present study was carried out in Wielkopolska National Park and its buffer zone, which are protected under Natura 2000 as Special Areas of Conservation and Special Protection Areas. The aim of the study were (1) to assess the impact of agriculture, with special attention on fertilization, on groundwater, and running water quality and (2) to designate priority areas for implementing nitrogen reduction measures in special attention on protected areas. In our study, high nitrogen concentrations in groundwater and surface waters were detected in the agricultural catchments. The results demonstrate that in the watersheds dominated by arable fields, high nitrogen concentrations in groundwater were measured in comparison to forestry catchments, where high ammonium concentrations were observed. The highest nitrogen concentrations were noted in spring after winter freezing, with a small cover of vegetation, and in the areas with a high level of nitrogen application. In the studied areas, both in the park and its buffer zone, unfavorable N:P and N:K ratios in supplied nutrients were detected. Severe shortage of phosphorus and potassium in applied fertilizers is one of the major factors causing leaching of nitrogen due to limited possibilities of its consumption by plants. 相似文献

The effects of ten generational zinc or cadmium pre-exposure on metal tolerance among beet armyworm Spodoptera exigua individuals were compared. These effects were assessed in animals from the 11th generation, reared on a diet either uncontaminated or contaminated with metal (cadmium or zinc). The survival rate of larvae and the degree of metal accumulation (in larvae, pupae and moths; among larval organs: gut and fat body) were analysed. Catalase, superoxide dismutase and glutathione transferase activity in larval organs of individuals subjected to different metal treatments were also measured. Animals transferred from control rearing to metals (cadmium or zinc) in the 11th generation, as well as those from multigenerational zinc treatment, but not from multigenerational cadmium treatment, had a significantly lower survival rate than control animals. Insects from the groups with the high metal treatment had high bioaccumulation factors (above 3.7 and 2.3 following cadmium and zinc, respectively). Cadmium (but not zinc) pre-exposure had a significant effect on metal accumulation in larvae. Multigenerational metal pre-exposure seemed to have mainly a negative effect on glutathione transferase activity in the gut of larvae from the 11th generation, in the case of the individuals exposed to metal other than that used in pre-exposure treatment or kept in control conditions. However, in the case of zinc pre-exposure, such effect was only apparent when zinc was replaced by cadmium. The long-term effect of cadmium on catalase activity in larvae was found. 相似文献
