Item type:Article, Access status: Open Access , An attempt to identify traffic related elements in snow(Wydawnictwa AGH, 2013) Adamiec, Ewa; Wieszała, Robert; Strzebońska, Magdalena; Jarosz-Krzemińska, ElżbietaThe main objective of this article is an attempt to use snow as an indicator in the process of assessing and identifying vehicle-derived elements pollution. The aim of the present study is to characterize traffic-related elements in snow collected from three sites: a parking place, a highway and a relatively unpolluted airfield. Several recent studies suggest that road traffic is considered to be one of the major sources of environmental pollution in urban areas. In order to avoid the problem of low emission from household furnaces, samples were collected far away from residential buildings. Snow located near roads with heavy traffic seems to be a very useful tool and indicator of traffic-related elements released into the environment. Snow acts as a natural filter for various chemical elements and particles. Snow is an efficient scavenger of aerosol and air pollutants, usually remains on the ground for sampling after the event, moreover, snowmelt contaminates soil. In the present study filtered (0.45 µm) samples of melted snow were analyzed with ICP-MS. The results show significantly higher concentrations of elements in snow collected at the parking lot and at the highway when compared to samples taken from a relatively unpolluted airfield. Research on exploitation dust (break, tire, clutch) was performed with SEM-EDS.Item type:Article, Access status: Open Access , Contamination assessment of Krakow Valleys Landscape Park’s surface and wastewaters(Wydawnictwa AGH, 2014) Strzebońska, Magdalena; Jarosz-Krzemińska, Elżbieta; Adamiec, EwaThis research consisted of a physico-chemical evaluation of the streams and wastewaters within Krakow Valleys Landscape Parkin the Kluczwody, Bolechowicka, Będkowska and Kobylańska valleys. The following set of parameters were determined in the samples: pH, Eh, conductivity, oxygen content, concentration of metals' cations and selected anions. The results revealed that the wastewaters discharged as well as the streams that feed into the Rudawa river are mainly polluted with nitrates. Additionally, the examined wastewaters contained a high concentration of phosphate exceeding class II purity maximum permissible values.Item type:Article, Access status: Open Access , The effect of de-icing roads with salt on the environment in Krakow (Poland)(Wydawnictwa AGH, 2019) Kostka, Anna; Strzebońska, Magdalena; Sobczyk, Maciej; Zakrzewska, Marta; Bochenek, AnnaThe de-icing of roads and streets in the winter season is a necessity in many European countries, where the mean day temperature drops below 0°C for long periods. Among the many chemicals used for winter road maintenance, the most popular in Poland is sodium chloride in various forms and mixtures, due to its relatively low price and availability. This agent, however, contributes to the increase of salinity in the soil environment and may lead to disturbances in soil properties and premature plant necrosis. The impact of the usage of chloride salts on the soil environment was researched in Krakow’s city centre by means of the examination of soil samples collected prior to the de-icing season (November) and afterwards (February) as well as snow samples taken in February. A general deterioration of the examined parameters (pH, conductivity, chloride concentrations, carbonate concentrations) was observed after the winter season, but still the results for most samples did not pose a serious threat to the soil environment or plants. This was mainly the result of the fact that the winter seasons in European countries have become increasingly mild and warm, which contributes to decreased usage of chloride salts. However, the state of soils in the Main Square was disturbing, as demonstrated by the clearly elevated chemical parameters of samples, despite a ban on the use of salt in this area. These results indicate the most probable reason for the withering of trees growing there, leading to them being frequently replaced.Item type:Doctoral Dissertation, Access status: Metadata only , Wpływ powodzi 1997 roku na zanieczyszczenie dorzecza Odry metalami ciężkimi(Data obrony: 2000) Strzebońska, Magdalena
