This paper concerns the characterization of temporal and spatial variability of thermal and air quality conditions within the area of Gdańsk – a port city The classification of thermo-physiological conditions was done with the use of UTCI (Universal Thermal Climate Index) and the quality of air was determined with the use of CAQI (Common Air Quality Index). The analysis was done on the basis of meteorological...
For the primary purpose of minimizing carbon dioxide emissions in a megalopolis, an optimization model that remarkably reduces carbon emissions for the megalopolis, which is based on the inexact chanceconstrained linear programming (ICCLP) method and incorporates interval linear programming (ILP), and chance constrained programming (CCP), has been constructed. The corresponding net emissions of carbon...
This paper studies organic matter (OM) and nitrogen (N) distributions at different depths of an earthworm packing bed, and the N distribution in situ solution in artificial soil (AS). The contents of OM, nitrate nitrogen (NO₃-N), ammonia nitrogen (NH₃-N), and total nitrogen (TN) changed along with the depth of AS. The results of N concentration in situ solution indicated that 35 cm to 40 cm thickness...
Pharmaceutical wastewaters are generated through complex manufacturing processes that contain a variety of organic and inorganic constituents, and are usually characterized by a high concentration of chemical oxygen demand (COD), suspended solids, dissolved solids (salts), toxicity, and refractory compounds. In this paper, wet peroxide oxidation (WPO) was adopted to treat pharmaceutical wastewater...
An allocation scheme of water pollutant reduction is the key procedure to implement a watershed total maximum daily load (TMDL) program. In order to improve the equity for the allocation scheme of water pollutant load reduction, five indexes involved in allocation processes were selected from fields associated with society, environment, economics, and resources. The weights of these indexes were determined...
Polish waste management systems currently are under development and modernization in order to adjust to European Union standards. Mechanical biological waste treatment systems installed in so-called regional municipal solid waste treatment plants are being developed. This type of plant needs to be operated in order to obtain required levels of recycling and waste recovery and to limit the amount of...
Our paper presents a study on the middle reaches of the Ina River. Select physical and chemical indicators were analyzed in order to evaluate water quality. It was determined that the studied river was subjected to strong anthropopressure, and factors declassifying river water included CODCr, TP, general hardness, and alcalinity. A high level of biogenic elements was additionally increased by pollution...
The aim of this study was to review papers about odor emissions from livestock production published between 1997 and 2013. The study concerned three animal species: poultry, swine, and dairy cattle. The results of the research are presented in different units, making it difficult to compare them. For this purpose, the odor emission factors were converted with respect to 1 LU (livestock unit=500 kg)...
LCA is a popular tool widely used to assess the environmental impact of waste management systems, which is illustrated by the substantial number of LCA computer models specifically addressing this subject. Due to the complex nature of waste management modelling and the range of country-specific data, as well as lack of harmonization, it has been observed that there are large discrepancies between...
Soil erosion caused by natural or anthropogenic factors represents a widespread problem with a range of negative environmental consequences. Various measures and works are being carried out to mitigate and prevent the direct and indirect effects of erosion. These actions often cannot be implemented in a whole region prone to erosion due to limited financial or human resources. Therefore, identifying...
An evaluation of OCP residue (OCPs = α, β, δ, γ-HCH isomers, p,p’-DDE, p,p’-DDD, p,p’-DDT) from the CauBay River and the KieuKy area in Vietnam was carried out. The CauBay has played an important role in irrigated water supply for agriculture activities in KieuKy downstream. The OCP concentrations of sediment and soil samples were analyzed and results indicated the wide extent of contamination of...
Traditional ploughing cultivation can contribute to soil erosion as well as to other symptoms of soil degradation, leading to a decline in its biological and production potentials. An alternative to conventional tillage is offered by simplified cultivation systems consisting of shallower and less intensive interference into the soil physical structure or even complete abandonment of cultivation treatment...
The majority of ecological research on the food web has so far focused more on sea and lake ecosystems than on peatbog habitats. The primary objectives of this paper were to analyze the protozoa, metazoa, and macroinvertebrate assemblages in different types of peatbogs, and to assess the influence of potential predators on protozoa communities. Sampling was done in six peatbogs from May to October...
The aim of our study was to determine the potential of forest woody waste biomass as a source of renewable energy. The research is a case study of one forest division in Poland. The research was made in Staszów Forest Division, Świętokrzyskie Voivodeship, eastern Poland. The division is part of the Regional State Forest Directorate in Radom and covers a forest area of 19,335.12 ha. The research covers...
Agricultural activity results in water pollution from nitrogen and phosphorus compounds. Increased concentrations of nitrogen compounds pose a threat to animal and human health. The purpose of this study was to determine the impact of agriculture in a catchment basin on the level of surface water pollution from biogenic compounds. Spatial analysis of the land cover was conducted using GIS and was...
Spatial diversity and total area of thermal-humid regions have been assessed and, in addition, climatic water balance values have been calculated, employing specific time-frames up until the year 2020. The latter calculations have been performed taking into account temperature averages for the period 1971-2000, and constant precipitation. In order to designate thermal-humid regions the Daunbenmiere...
Two rice varieties, one perchlorate-tolerant (Gannuoxiang, GN) and the other perchlorate-sensitive (IR65598-112-2, IR), were exposed to 20, 200, and 400 mg/kg soil perchlorate to investigate their physiological responses and perchlorate accumulation. It was found that perchlorate decreased leaf chlorophyll content in both rice varieties. The activities of superoxide dismutase (SOD) and catalase (CAT)...
Global warming and climate change have become issues that recently have caused much concern in the world. Countries that perform their economic activities without thinking about future generations have had to focus on “sustainability” issues since local and global environmental issues have been experienced. In this context, global warming problems have become one of the most important environmental...
Electroplating sludge and associated waste products comprise complex mixtures of metallic elements and may cause serious environmental pollution if discharged without treatment. An effective light industrial process is modified to selectively extract and recover copper and nickel from electroplating sludge. The procedure was developed on a laboratory scale and validated in a small pilot plant. Extraction...
Polybrominated diphenyl ethers (PBDEs) are a class of synthetic halogenated organic compounds used in numerous polymer-based commercial and household products such as textiles, furniture, and electronics, to increase their flame ignition resistance and to meet increasingly strict fire safety standards. Release of PBDEs to the environment can occur during manufacturing and processing operations, throughout...
