Sound pollution is an ever growing problem in modern society, and especially urban environments. In this paper, we investigate if how artificial sounds can improve the experience of visitors park with a lot traffic noise. By using mobile app, control sound playback by selecting natural they like, such as birds or waterfall, setting volume. This process adding to existing environment results aug...

Important problem of modern environmental epidemiology is study and assessment of air-pollution health effects. For reasonable assessment, it is very important that the models used must be epidemiologically sound and robust in terms of the persistence of the model behavior during changes in the model parameters. For the solving this problem, we introduce notion of ”adequate models” which is sim...

Although it is well known that metals pollution can cause neurotoxic effects, scientists are currently divided about the neurodegeneration hypothesis. That is, some scientists accept, while others fail to accept, the hypothesis that metals/metalloids, at exposure levels below those capable of causing neurotoxicity, can cause neurodegeneration—progressive or worsening neurological disease. Partl...

Submerged arc welding contributes to approximately 10% of the total welding. Approximately 10% -15% of the flux gets converted into very fine particles termed as flux dust before and after welding, due to transportation and handling. If welding is performed without removing these very fine particles from the flux, the gases generated during welding are not able to escape, thus it may result int...

Background and Objective: Indoor air pollution in hospitals could be a serious health threat to the patients, medical staff, and visitors. In previous studies, the importance of paying attention to air quality during the Coronavirus pandemic has been proven. In this study, the effect of visiters' presence under normal conditions and the imposition of hospital restrictions at the time of pandemi...

Successful implementation of water-quality management requires accurate scientific knowledge of water systems and sound judgment about environmental policy. This dual requirement calls for interactions between water scientists, managers, and policy experts who can jointly interpret and synthesize the data necessary for decision-making. With regard to non-point source (NPS) pollution in the Unit...
