The significance of local meteorological stations in research planning
87-91Views:186The goal of research planning is to optimize human and material resources while maximizing efficiency. If there are databases that can be used as a substitute for own data collection, effective research can be facilitated by reallocating resources. In the case of environmental studies, the knowledge of the climatic conditions of the study period is known to be a key factor in research planning process.
In the present study, the data of our meteorological station in our research area (known as “Szamárháti Tanya”, Kesznyéten, Hungary) was compared with the measurements of meteorological stations operated by the competent water authority. Stations were taken into the study within a 10 and 20 km radius over a period of 21 months, to determine which provided more relevant data from the area.
During the evaluation of results, the relationship between the local and regional weather stations were determined, and deductions were made from the obtained results to support the decision which of the targeted investigations could be of greater benefit.

Examination of lead absorption ability on chernozem soil and the observation of the accumulation effect of Lactusa sativa L. in pot experimentation
101-104Views:115In our research a chernozem soil sample formed on loess was collected from an area under cultivation. Our aim was to determine the lead adsorption capacity using a soil column experiment. The study showed saturation of lead content of the soil. The lead accumulation capacity of Lactuca sativa L. was measured in the sections of roots and leaves applying pot experiments. It could be observed that the lettuce accumulated lead easily from the chernozem soil. The lead content was increased in the analyzed sections of the plants against an increasing lead content.
