Development of a monitoring network on Lake Balaton, Hungary

Autor: József Hlavay, Klára Polyák

Publikováno v: Microchemical Journal. 79:137-143

A monitoring system has been developed to characterize the bottom sediments of Lake Balaton. Samples were collected inside of the lake, from the top layers to 60 cm in depth. The samples were dried at room temperature and then sieved through 2-mm and

Evaluation of combined measurement uncertainty of the determination of Mn content in sediment samples

Autor: Klára Polyák, József Hlavay

Publikováno v: Accreditation and Quality Assurance. 6:310-316

Combined uncertainties of an analysis of elemental content of sediment samples were evaluated. A monitoring system has been designed and implemented for the characterization of the environmental conditions of Lake Balaton in Hungary. Sediments sample

Fractionation of elements in sediment samples collected in rivers and harbors at Lake Balaton and its catchment area

Autor: Márta Weisz, Klára Polyák, József Hlavay

Publikováno v: Microchemical Journal. 67:207-217

A monitoring system has been developed to characterize the water quality of Lake Balaton. Sediment samples were collected in rivers and harbors around the lake and its catchment area. A modified four-step sequential leaching procedure was applied for
