Opis:
Introduction. Man is the only being that has created an artificial environment, or civilization. The development of civilization entails changes in the environment. The rapid growth of the impact of human economic activity has led to such changes that are able to threaten not only other living creatures but also themselves. Increasing environmental pollution are well-known factors negative influencing on human environment. Is now a global problem. Anthropogenic pollution contribute to the unfavorable demographic changes and grooving number of health problems of the population. Unfavourable demographic changes manifest themselves as not only increment in the number of deaths and malformations (defects in the reproductive organs), but also as decrement in the fertility rates being the consequence of increasing the growing problem of couples infertility. There is observed the increasing role of male factor in the couple infertility problem. In some developed countries its participation rate reaches 50%.Objective. The aim of the study is to assess the impact of environmental pollution on human development and reproductive function of male gonads.Material and methods. The study was carried out using the method of data analysis published in the works and scientific reports.Current state of knowledge. The paper presents information on identified environmental pollution with proven adverse effects on the development of the gonads and the their reproductive function. There are also known possible negative impacts of environmental pollution on carcinogenesis in male gonads.Wider awareness of the negative impact of environmental pollution and attempts put emphasis on primary prevention can give better long-term effects than increasing spending on the therapies of developmental disorders as well as gonadal dysfunctions symptoms including fertility problems.Conclusions.Among the environmental pollutants there are many chemicals adversely affecting the organogenesis as well as reproductive function of testicles.Many of these contaminants are pesticides or chemicals currently approved for use in agriculture and industry, including the food and cosmetics industry.Those chemicals, adversely affecting organogenesis and testicular generative function, are present in air, water and foods, packaged foods and everyday objects - including clothes (ingredients sponges), perfumes, creams and detergents.The increase in environmental pollution coincides with the deterioration of sperm quality and reduction in male infertility in highly civilized countries.Striving for continuous reduction of the environmental seems to be necessary to stop the growing problem of couples infertility.

Opis:
In the paper, the authors made an analysis of mechanisms of the toxic components formation of exhaust gases in the direct injection engines. The genesis as well as the typical engine construction solution with the use of direct injection in diesel engines and these with positive ignition was developed. The typical construction solution of the Common Rail (CR) system, which is one of many elements increasing the purity of exhaust gases, was also presented. The basic advantages of direct injection, especially in case of the positive ignition engine, were also briefly described. Then, the mechanism for the formation of toxic components of exhaust gases in the direct injection diesel engines was presented. Moreover, the definition and dependency on the indicated mean effective pressure were shown, and the closed indicator graph, which is indispensable to calculate values of this pressure, was also (graphically) presented. In this paper, the mechanisms and processes, with the use of which it is possible to reduce the emission of toxic components of exhaust gases, were quoted. The exhaust gas recirculation with the EGR valve, which allows supplying the exact amount of gases to the engine inlet system, is such an example. The advantages of using this type of solutions were described, and a typical construction solution was presented in the diagram. The paper was completed with a conclusion, which emphasised the importance of direct injection on reducing the emission of toxic components of exhaust gases.

Opis:
Exhaust gas emissions from ships are increasingly polluting the air environment seriously. Therefore, the MARPOL 73/78 Annex VI is applied for all ships from 2017, Annex VI provided that the concentrations of NOx,SOx CO contained in ship’s exhaust gases must be less than 6.4 g/kWh, 0.6 g/kWh, and 5.5g/kWh respectively. Today, there are many solutions to reduce pollution emissions from exhaust gas of ships, such as improving combustion, using oil emulsion, using biofuel,…However, these solutions also have a handful of disadventages such as being unable to thoroughly resoulve problems, high cost, and very difficult to improve the quality of ship exhaust gas emissions for old ships. Exhaust gas treatment method uses a centralized treatment system where exhaust gas from the thermal engines is taken in a centralized treatment system before discharging into the air. After centralized treatment system, in comparision with raw exhaust gas, soot can be reduced by 98%, NOx can be reduced by 75%, SOx can be reduced by 80%. This method of treatment is not only low cost, good quality but also make marine heat-engines still use traditional fuels as well as need not improve its structure.

Opis:
Electric vehicles are increasingly present on the roads of the whole world. They have the opinion of ecological vehicles, not polluting the environment. Society is more and more often persuaded to buy electric cars as an environmentally friendly solution but is this for sure? Electric cars need quite a lot of electricity accumulated in batteries to drive on a long range. During the charging process, this energy is obtained from the electricity network, to where it is supplied by power plant. Electricity production from renewable sources is a privilege for the rare. However, electric cars are charged from the electricity grid, which in large part energy comes from non-renewable fuels. The efficiency of energy production in power plants and the energy transmission and conversion chain causes that only part of the energy produced in this way goes to the vehicle’s wheels. Although the power plants are equipped with more and more efficient exhaust gas cleaning systems, they do not clean them up to 100%. Sulphur, nitrogen, mercury and heavy metals remain in the exhaust. The article is an attempt to answer the question whether the total emission of toxic components associated with the use of an electric vehicle is not bigger than in a traditional internal combustion engine.

Opis:
The commonness of metal contamination, even at considerable distances from industrial centers and intensively used economic areas, has become the interest of many researchers. The issue of evaluating the state of the environment with the help of living organisms has become a very important part in the control of the natural environment. Honey bee (Apis mellifera L) is a good bioindicator as it is inextricably linked to the natural environment in which it lives. The aim of the research, and at the same time the main assumption of the study, was to evaluate the effectiveness of honeybees (Apis mellifera L) as bioindicators for the presence of Cu, Cr, Zn, Mn, Fe in the urban area (example of Bialystok city). The study includes pilot studies covering three sampling periods (March, June and September 2015). Analyses of metals were made by ASA method. The results showed the presence of Cu, Cr Zn, Mn and Fe in all bees samples. An increased content of Cr in bees was also found, which may be the result of the presence of this element in the environment (air, soil, water, plants, pollen) and in the impregnation agent applied to protect wooden elements of the bee hive. The research showed seasonal variation of metals in bees bodies. The main sources of studied metals in bee samples seem to be motorization, industry, and municipal economy within the urban area. Statistical calculations showed a common origin of majority of studied metals. Bee studies for metals contents can be an important element of a bio-monitoring of changing natural environment as a consequence of anthropogenic activity.

Samples of 5 vascular plant species: Achillea millefolium L., Artemisia vulgaris L., Festuca gigantea (L.) VILL., Ranunculus acris L. s. str. and Vicia angustifolia L. were collected near Fuel Storage Station, Chemical Fibre Factory “Wistom” in Tomaszów Mazowiecki and Sewage Treatment Plant in Sulejów. Genotoxicity of environmental pollution was analysed using micronucleus assays in pollen mother and root tip cells in comparison with plant material collected in the Tatra and Babia G óra National Parks. Abnorm alities in morphology of plants growing in polluted areas were also found. The cytogenetical analyses revealed positive correlation between the percentage of micronuclei and the presence of heavy metals in soil. Pollen mother cells (germ line) were found more susceptible to DNA damage as compared with root tip cells (somatic line).
