Analysis of Littering in the protected areas of the Czech Republic
Hejdová, Jiřina ; Benešová, Libuše (advisor) ; Kotoulová, Zdenka (referee)
The problems of litter are now getting to the forefront of attention in the realm of waste research. The phenomenon of littering is monitored especially in towns, but not so much outside the urbanized areas. Waste represents, for both esthetic and conservationist reasons, an undesirable phenomenon. This holds true for the protected areas in particular. This Master's Thesis is concerned with the analysis of litter, which should be the first step in the prevention and solution of the problems of littering. Three protected landscape areas and two national parks were chosen for this survey. Two tourist trails were selected in each protected area - the main and the minor one. The collection of litter was carried out in spring, summer and autumn. Collected waste was categorized at first and then a number of pieces, weight and volume were set for each category concerned. The largest amount of litter was collected in the National park Krkonoše and the smallest in the Protected landscape area Kokořínsko. The largest number of litter pieces is represented by cigarette waste, followed by plastic and hygienic waste. PET bottles were the most common type of litter pieces found in the category of beverage containers. Three quarters of all litter was found on the main trails. The most litter was collected in the...

Výsledky prezentované v závěrečné zprávě lze shrnout: 1. Přirozený dřevní odpad je možno charakterizovat jako standard, se kterým je nezbytné jiné rostlinné projekty použité jako energetickou biomasu srovnávat. 2. Energetické rostliny pěstované na polích obdělávaných běžnými pěstebními postupy jsou těmito postupy a půdním biotopem velmi výrazně ovlivněny z hlediska složení inertní složky sušiny biomasy. 3: Většina druhů energetických rostlin jsou charakteristické zvýšenou schopností čerpat z půdy významná množství těžkých kovů, pokud jsou v půdě obsaženy. 4. Emisní charakteristiky CO, THC a persistentních látek lze ovlivnit konstrukčním řešením spalovacího zařízení. 5. další významnou podmínkou nízkých emisí je standardní příprava paliva. 6. Absolutních emisí persistentních látek typu PCDD/F a PAH lze pro standardizovaná paliva a na kotlích umožňujících zaručit vhodné podmínky dosáhnout takových, že splňují požadavky na tyto látky stanovené pro velká spalovenská zařízení dle nařízení vlády č. 354/2002 Sb. 7. Absolutní emise látek typu PCB jsou u biopaliv řádově nižší než požaduje nařízení vlády č. 354/2002 Sb.
