MONITORING OF LANDSCAPE COMBINATIONS AND CONCOURSES IN THE HUNGARIAN DANUBE-BEND

In Hungarian Danube-bend the flora of the area is very diversified due to climatic factors. Numerous species of flora characteristic of the area are under protection. The Danube-bend and vicinity is one of the most well-known part of Hungary, rich in historical relics and in natural assets. The city of Vac occupies a central place in the Danube-Bend Region. Among Vac's attributes, we can find rare and invaluable cultural and historical values. The most significant natural attribute is the Grove of Vac near the Danube bank. The example of the Grove of Vac is of country-wide importance in many aspects - it is part of the Duna-Ipoly National Park - though local protection is reasonable regarding the treatment and links because of the pollution of the environment. The natural advantages are affected by air pollution due to the increased industrial, commercial, and economic life of the city. Nowadays, the research of environmental pollution comes to the front because of the importance of heavy metals in the landscape classification. Even though the heavy metals are a natural component of the environment, we have to look them toxic materials. This paper focuses on the pollution analysis I carried out with various plant samples. It shows the main toxicology pollutants present in different landscape combinations and concourses. In tree specie, like Salix alba, near the band of No. 2 motorway I observed 5-8 times more values as compared with samples from the Duna-Ipoly National Park and nearly all kinds of heavy metals was elevated in Plantago major. In the life of the ecosystem, the primary source of heavy metals is the No. 2 motorway and the secondary is the pollution of the Danube bank.
