The mediterranean’s karst basin waters is the topic of this research paper. The aim of the research is to help protect the karst underground waters through wastewater management of the basin’s area. The main difficulty for our research was a shortage of knowledge in the identification of the karst’s hydrological system, such as in the case of a researched system where the system’s inlet and outlet...
This study investigated the solid waste characterization of the city of Kocaeli. With this aim solid waste groups were analyzed for sub-municipalities of the city. Representative sampling points were determined in municipalities with populations over 5,000. Four different socio-economic groups (the downtown district plus low, intermediate, and high income levels) were investigated in the study. Characterization...
Our study aimed to determine the effects of conventional diesel fuel modification with biodiesel addition on the activity of soil microbiota. Diesel fuel, biodiesel and their mixture in a concentration of 5% (w/w) were introduced into soils – light loamy silty sand and light silty loam. Based on the obtained results, reduction in the content of live microbial biomass was found, irrespective of the...
Twelve consecutive seasonal surveys were carried out in Klaipeda port, Lithuania, in 2006-08. Water parameters such as temperature, pH, salinity, dissolved oxygen, particulate material, nutrients (N/NH₄⁺, N/NO₂⁻, N/NO₃⁻, P/PO₄³⁻), petroleum hydrocarbons, and heavy metals (Cu, Zn, Ni, Pb, Cr, Cd, Hg) were determined in both the surface and near-bottom water horizons. Total contamination of port waters...
The Legnica-Głogow Copper Mining District has been the site of metal mining for more than 50 years. Intensive environmental actions have, more recently, been aimed at reducing emissions of harmful substances in the region. We compared the blood lead concentrations of children resident in the copper smelting district in southwestern Poland in 1995 and 2007. The sample included 1,405 children, 7-15...
Street-side trees in cities are characterized by poor health, with high salinity and pH, that leads to an early death. The main reason is soil salinity caused by winter road maintenance using salt (NaCl). Our research comprised three species of trees. A dependency was determined between their vigour and health and the content of biogenic elements, typical pollution, and indicators of ionic balance...
School buildings typically serve a number of functions simultaneously, owing to which they seem to be especially exposed to the expansion of fungi with wide enzymatic capabilities, including fungi of the genus Penicillium. In total, 34 isolates belonging to 20 species were obtained within two schools. The most frequently isolated species included: Penicillium chrysogenum, P. waksmanii, and P. citrinum...
Deposition rates of atmospheric particles were determined using previously published ²¹⁰Pb data in soils and air. The dry deposition velocities for moorland and woodland soils were 2.2±1.8 and 9±2 mm・s⁻¹, respectively. The ²¹⁰Pb concentration in rain was calculated to be 94±10 mBq・L⁻¹. The large (~4 times) deposition velocities in woodland relative to moorland soils is an indication of the degree...
A three-year field experiment was conducted in 2002-04 to evaluate the effects of soil tillage and weed control methods (including herbicides and their mixtures) on the content of polyphenols in edible potato tubers, cv. Wiking. The results obtained indicated that the content of polyphenols in non-peeled and peeled tubers depend on the methods of soil tillage and weeding, as well as on the years of...
Crude oil is a complex hydrocarbon whose introduction into the environment may be hazardous to aquatic and human life, and consequently a threat to natural resources. The severity of the impact of crude oil depends on a variety of factors, including characteristics of the oil itself, natural conditions such as water temperature and weather, and the sensitivities of receiving or impinging biota. As...
The purpose of our study was to assess whether the chemical composition of drinking water in the city of Szczecin, Poland, creates the correct environment in the oral cavity for promoting regeneration processes in the mineralized tissue of teeth. The drinking water samples were collected from a water treatment station, as raw and treatment water, and from consumer’s water pipes. The concentration...
Our study assesses environmental lead and fluoride pollution in West Pomeranian forests in Poland, on the basis of chemical analysis of antlers and skull bones of roe deer (Capreolus capreolus L.) from the surroundings of Szczecin and Drawsko Pomorskie, Poland. Lead was measured by atomic absorption spectrometry, and fluorides by using an ion-selective electrode. Our study indicates greater lead contamination...
The present work was planned to determine the median lethal doses (LD₅₀) and to evaluate the haematological and biochemical changes, and histopathological effects of the essential oils from eucalyptus Eucalyptus globules L. and clove Eugenia caryophyllus on liver and kidney of albino rats. The LD₅₀ was 2,334.4 and 3,597.5 mg/kg b.w. of eucalyptus and clove oils, respectively. Obtained data revealed...
Our study was a biological evaluation of soil contamination near a non-operating pesticide tomb. The soil contaminated with pesticides had a negative effect on the growth of crustaceans such as Heterocypris incogruens (Ostracodtoxkit test) and the development of plants such as Lepidium sativum, Sinapis alba, and Sorghum saccharatum (Phytotoxkit test). This adverse effect persisted up to 5 years following...
After a flood in 1997 that affected the basin of the upper and central Odra River (on selected dam reservoirs, including drinking water reservoirs), the operational water fill ordinates were lowered in order to increase the flood capacity of the reservoirs. One of these reservoirs is the Słup. Its main functions include: compensation of water outflow from the Nysa Szalona and flood protection. This...
The aim of our study was to investigate acute and chronic effects of the oil cleaner Simple Green (SG), crude oil (oil), crude oil and SG mixture (oil-SG) on rainbow trout (Oncorhynchus mykiss) in early development stages (embryos, larvae). The acute effects of SG, oil, and oil-SG mixture on rainbow trout embryos and larvae were investigated. The 96-hour LC50 values for embryos/larvae were: SG – 1,270/1,040;...
In this paper, an attempt is made to characterize PM₁₀ imission field in the area of Warszawa with regard to PM content of the metals As, Cd, and Ni. Particulate matter concentration measurements were performed within this agglomeration with the use of many measuring methods, different not only in respect of the sampler operation rules, but also of the accuracy, sampling frequency, and separation...
The aim of our study was to determine species biodiversity of yeasts and yeast-like fungi in the stratum of surface water of Lake Tyrsko, as well as to evaluate the condition of waters of that lake based on the isolated species of fungi. The study was carried out from June 2007 to June 2008. The isolation and determination of the number of fungal colonies were conducted with the use of the membrane...
Results of lead and cadmium contents in soil adjacent to European highway E30 in the East of Poland were presented in the study. Soil samples were collected at three distances: 0, 50, and 100 m from the track, and at two depths: 5-15 cm and 35-45 cm. Soil pH, content of silt and clay particles, organic matter content, types of underlaying rock and land use methods were tested. The total contents of...
The objective of this study was to compare chemical and microbial properties of sandy mine soils under young Scots pine, silver birch, and mixed pine-birch forest stands. The measured properties included the contents of organic C (Corg) and total N (Nt), the Corg-to-Nt ratio, pH, microbial biomass, basal respiration, and activities of dehydrogenase, acid phosphomonoesterase, and urease. Community...
