The samples of liver, kidneys and testes were collected from wild pheasants shot in the Podkarapacie region in contaminated (n = 5) and clear (n = 5) areas. Tissues were examined for the cadmium and lead concentrations by AAS method, as well as the activity of five hydrolases. The major site of cadmium accumulation were kidneys, the levels of Cd found in liver and testes were by 5-fold and 30-fold lower (P < 0.05), respectively. Similarly, Pb concentrations observed in the liver and testes were lower than in kidney, by 1.5-fold and 6-fold, respectively. The presence of four glycosidases and arylsulphatase in all examined tissues was demonstrated and N-acetyl-D-glucosaminiadase (NAG) was identified as the most active enzyme in all studied tissues. Significant differences (P < 0.05) were observed only in the level of NAG activity in liver of pheasants inhabiting the contaminated area as compared to the birds from the clear region (control group). We conclude that the determination of NAG in birds organs can be used as biomarker of environmental exposure to cadmium.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68904609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In studies as extractant was used: water, EDTA, acetic acid, formic acid, DTPA, ammonium lactate and calcium lactate. For analysis has been taken wool after one year cultivation of tomato and cucumber and wool after two years of mixed cultivation. The main aim of the analysis was to determine which extractant allows the greatest recovery of the iron from waste mineral wool. Current trends in the agriculture development and the fertilizer industry are aimed at maximizing the recovery of nutrients from waste for re-use. Demonstration of the effectiveness of the recycling of valuable trace elements contained in the mineral wool can make develop a method of wool utilization profitable. In addition, the high cost of fertilizer components makes a new type of medium containing nutrients obtained by extraction from mineral wool waste, can be an interesting option in the future. Implementation of this type of process is consistent with the objectives of Sustainable Development, as well as the environmental policy of the European Union. The proposed way to get iron from mineral waste wool consists of following steps: drying at 30 C for 24 hours, grinding to particles with a sieve size of 0.40 nm, extraction and phase separation. The studies included the effect of time, temperature and type of extractants on the efficiency of the process. The iron content in the samples was determined by spectrophotometric method based on the ferric ion complex of 2,2-pyridyl in a solution at pH of 3.1.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68905001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is one of the factors leading to increased interest in monitoring tests for their quality. Heavy metals are major water pollutants in Poland. The aim of this study was to determine seasonal variability in concentrations of cadmium, lead, zinc and copper in various reservoirs and water courses in the Wielkopolska region. Water samples were collected from lakes, large and small rivers and drainage ditches. These water bodies differ in land use in the surrounding. These were mostly rural. The study was conducted during the growing season from May to December 2012. Quantitative analysis of heavy metals was performed on the AA spectrometer Agilent 280Z. The results showed high seasonal variation in heavy metal contents in different water bodies. The concentrations of cadmium and zinc mainly depend on the date of discharge to water. Lead concentrations were caused by emissions and depended mainly on cultivation measures in fields. The highest concentration of copper was observed in the lakes, which could be due to the use of compounds that eliminate algal blooms. Under Polish law, all water bodies are classified into water quality classes I or II intended for drinking. Living conditions for cyprinids and salmonids were satisfactory in all the locations.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68905547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to estimate conditions of the environment in the vicinity of cement plant moss bag biomonitoring method was used. The aim of the study was to assess the relationship between the extent of air pollution with 40 K, 137 Cs, 210 Pb and the distance from the cement plant. The share of various radiation sources in the total 210 Pb activity concentration in mosses after exposure was also analyzed. Sampling sites were located in the forest near Opole (PL), in a line and at different distances from the cement plant. In test two types of moss bags, exposed simultaneously in the same places, were used. In the studies, activity concentrations of gamma-radioactive isotopes were determined in samples of moss before and after the exposure. In investigations the gamma-spectrometer with a germanium detector was used. From the obtained results the Relative Accumulation Factors ( RAF ) were calculated. In order to assess the extent to which radionuclides activity depends on the distance from the cement plant, correlation coefficients were calculated. It is hard to estimate the trends of radionuclides activity concentration changes with distance from the cement plant due to substantial discrepancies in the results. No significant relationship of radionuclides deposition on the distance from the cement plant was noticed.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68905360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subject of the study was a synthetic municipal waste water treatment plant effluent containing inorganic and optionally organic substances and to which the investigated micropollutants were added at a concentration of 500 g/dm. The obtained results were compared in terms of the degradation of the selected compounds in deionized water. It was found that the efficiency of the photocatalysis depends significantly both on the environmental matrix and physico-chemical properties of the compounds present in the treated waste water. The highest degradation efficiency was observed for the synthetic effluent that contained only inorganic substances. The degradation of bisphenol A and 17 -ethinyl estradiol exceeded 90 % (after 60-minute irradiation) and 17 -estradiol was decomposed completely. The observed phenomenon can be attributed to the process termed as sensitized photocatalysis, which was enabled by inorganic substances present in the synthetic waste water. This phenomenon was not observed for the synthetic effluent that contained both inorganic and organic substances, and moreover the degradation efficiency of the micropollutans was lower. These observations were also confirmed by the results regarding the decomposition of the compounds in deionized water. In order to describe the course of photocatalytic oxidation reaction rate constants were determined as well as degradation half-lives using the Langmuir-Hinshelwood kinetic model.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"92 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68905371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
