Introduction and objective: This paper is concerned with the harmful impact of nitric oxides (NOx) and particulate matter (PM) on humans. The objective was to determine which source of emission is the most urgent in terms of its reduction.Abbreviated description of the state of knowledge: In published epidemiological studies multiple notifications indicating the harmful impact of particulate matter on human health can be found. The harmful impact is underscored by the increase in the number of hospitalisations owing to diseases of respiratory and cardio-vascular systems, as well as by the rise in general fatality rate. The analysis of the PM impact on the human body is prompted by the fact that its detrimental effects are not clearly defined. Additionally, nitric oxides contribute to the increased number of exacerbations of respiratory disease and are a factor increasing susceptibility to development of local inflammation. Conclusions: The following study is meant to show that the air pollution which derives from vehicles (NOx and PM) has a significant impact on human health. This applies particularly to residents of cities and big towns. This issue has gained special importance in Poland. According to the data from the Central Statistical Office, the increasing number of vehicles in use and their age lead to increased emission of the pollutants considered.

Opis:
Introduction. Molecular studies have confirmed the silent circulation of enterovirus (EntV) and hepatitis A virus in the environment, even in the absence of clinical manifestation. Viral pathogens are among the major causes of disease outbreaks, particularly in the bigger cities and both in the developed and underdeveloped nations. Materials and method. Between June 2016 – June 2017, 97 samples of drinking water, river water polluted with sewage and blood were selected and obtained from high risk communities in Pakistan. Negatively charged membrane filters were used to concentrate the virus, followed by the use of specific PCR primers set for quick identification of the waterborne viruses. Results. Enteroviruses were recovered from 40%, 28.57% and 33.33% of river water polluted with sewage samples in Lahore, Islamabad and Rawalpindi, respectively, while the presence of 13.13% and 11.76% of viral load was also confirmed in the drinking water of Lahore and Rawalpindi, respectively. A high prevalence of HAV (12.5% and 21.05%) was also verified in the clinical samples. Phylogenetic analysis indicated close resemblance of HAV isolates with the Indian strains. This study is the first ever comparative analysis of the EntV and HAV isolated from environmental samples and clinical specimen on a molecular level. Conclusions. The parallel surveillance of EntV and HAV in the river water polluted with sewage, and clinical samples is quite helpful for controlling and reducing the disease burden of the waterborne illnesses.

Opis:
Introduction. Inaudible but ubiquitous environmental infrasound undoubtedly affects the frame of mind and health of humans. Objective. The object of the study is to prove that civil engineering objects can be sources of infrasound, and a review of the literature on effects of infrasound on the health of people and animals. Methods. Computer simulation of an air flow around a typical element of outdoor infrastructure. The simulation was carried out using the author’s computer programme, based on Discrete Vortex Method algorithms. Results and conclusions. The numerical experiment clearly proved that industrial objects can be sources of infrasonic noise during windy weather. The picture of air flow around a cylinder shows that regular turbulent motion is a source of sound with one dominating frequency. The sound once generated propagate far from its source. Frequency and intensity of the sound depends on wind velocity and shape of the object. Further research in this area are advisable.
