The three-year field experiment comprised 7 treatments: a non-fertilized soil (control treatment) as well as a soil fertilized with mineral fertilizers, cattle manure, green waste compost, sewage sludge, compost from sewage sludge and straw as well as with a mixture of sewage sludge and hard coal ash. Maize cultivated for silage was the test plant. The lead content in the above-ground parts of plants and in the soil was determined using ICP-AES method. During the research, no lead pollution of the soil or the above-ground parts of the maize was found. No statistically significant effect of fertilization on the lead content in the maize was found or the fertilized plants contained considerably less of the element than the control plants. The lowest weighted mean content of lead was found in the maize fertilized with the green waste compost, sewage sludge as well as with the compost from sludge and straw. Soil with the lowest lead content was the soil of the treatment fertilized with organic materials. The soil fertilized with the green waste compost (all the years), sewage sludge (2 year) as well as with the mixture of sludge and ash (1 and 2 year) contained significantly more lead than the soil fertilized with mineral fertilizers.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68904591","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}

Such modifiers include organic metal salts which are soluble in fuels and tend to form metal oxides under combustion process conditions, improving the oxidizing properties of fuels. The modifier, described in this paper was used in liquid fuel combustion tests, showing a desirable effect of reducing CO, NOx and hydrocarbon emissions. For such modifiers to be approved for use, examination of their physico-chemical, toxicological and ecotoxicological properties is required according to REACH Regulation. REACH is intended, first of all, to provide appropriate protection to the environment and human health, while striving to maintain competitiveness of European enterprises in the global market. Discussed in this paper are the results of selected tests of the effect of an iron-based modifier for liquid fuels on human health and on the land and air and the aquatic environment. The modifier was subjected to physico-chemical analyses, and toxicological and ecotoxicological tests in accordance with good laboratory practice and OECD guidelines. The test results indicate that the modifier is a safe substance, posing no hazard to human health or the environment.","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":"68904666","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 was examined by analyzing the influence of the atmosphere with various oxygen content on the decomposition rate of the polypropylene composite. It has been found that in the air atmosphere, the initial decomposition temperature is close to 200 C. Lowering the oxygen concentration in the atmosphere to 2 % results in increase of composite decomposition temperature to almost 240 C. Decomposition components were identified in the methylene chloride extract from composite and in the condensed reaction products. Rate of decomposition conversion at initial stage below 0.2 was estimated as a system of equations: zero order path r = k1 for polypropylene degradation and first order path r = k2[O2] for oxidative decomposition. A brief safety analysis is performed identifying the possibility of exceeding an explosion limit under certain conditions. The best way of mitigating the fire/explosion hazard is lowering the oxygen content below 2 % vol., especially for processing of recycled polypropylene.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68905300","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}

As a model of surfactant linear alkylbenzene sulphonate (LAS) was used. Different concentrations: 10, 100 and 200 mg/dm of LAS was applied. The granulometric analysis showed that the pure activated sludge was composed of particles with a size of 1 m to 2 mm. The largest and fastest changes in the distribution of sludge floc size after the addition of a surfactant at a concentration of 100 mg/dm were observed. The flocs with a diameter above 0.8 mm disappear and the average diameter over volume of particles decrease from 0.29 to 0.19 mm. Doubling the dose of surfactant causes the flocs aggregation. The sludge flocs capability for break-up and aggregation is not proportional to the concentration of LAS. Addition of LAS to the sludge results in decrease of the sludge volume index. This study showed that granulometric measurement may help to estimate an impact of chemical substances contained in wastewater on activated sludge.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"22 1","pages":"51-56"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68905057","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}
