HEAVY METAL CONCENTRATION AND DISTRIBUTION OF SNOW AND LICHEA SAMPLES IN URBAN AREA: CASE STUDY OF JELGAVA

(STEF92 Technology, 2017-06-20, Jovita Pilecka)

Industrialization and urbanization have led to environmental contamination with heavy metals worldwide. In urban environment, the large inputs of anthropogenic contaminants in atmosphere are arising from mobile sources and stationary sources.Taking samples from all depth of snow, data can be obtained from persistent snow cover to the sampling time. Snow samples were collected in each sampling plot taking from 1.0 to 1.5 kg of snow. The average depth of snow was between 6 and 10 cm. The aim of study was to determin...

The European Union has set a target to cut its greenhouse gas emission levels by 80% to 95% until 2050, if compared to 1990. Agricultural soil is an important carbon store and food provider in the world as well as greenhouse gas emission reducer via carbon sequestration. In order to assess the climate change mitigation effectiveness of the measures, it is necessary to obtain statistically significant data before and after the implementation. The greenhouse gas measurements from soil are commonly determined using s...

THE CHANGES OF LAKE HYDROLOGICAL CYCLE: A CASE STUDY OF LAKE USMA IN LATVIA

(STEF92 Technology, 2017-06-20, Inga Grinfelde, Anda Bakute, Kristine Steinberga, Jovita Pilecka)

Lake Usma is unique with hundred years' old nature reserve and Natura 2000 territories in one part of the lake and developing the tourism industry in other part of the lake. During last ninety years, the water level of Lake Usma increased for approximately one meter, which caused coast erosion, changed soil ground water level in large territories around it and it is regarded to be a major factor for lake ecosystem functioning. To find sustainable management solution of Lake Usma, there is a necessity to understand...
