Cím:Determination of Recent Concentration of DDT and its Metabolites in Breast Milk in the Teaching of Behaviors of Persistence Organic Compounds / Zoltán Juvancz, Edina Garai, Loránt Szabó, Rita Boda-Kendrovics, Gabriella Köteles-Suszter
Megjegyzések:The problem of the persistent organic pollutants (POP) is an important part of the education program of Environmental Studies. The literature data refer several unwanted side effects of the intensive use of DDT. On the other hand the widely spread malaria epidemic infection makes the use of DDT necessary even today. The occurrence of DDT and its metabolites is a good representative of the persistency of such pollutants in the human breast milk. The samples were donated by university students and young teachers. This way the students could get personal involvement of the topic and measurements. The conventional and QuEChERS sample treatments were applied and their effectiveness were compared. GC-ECD instrumental analyses were used with parallel columns to demonstrate the selectivity and sensitivity of the required analysis. The results demonstrate the presence of DDE traces in breast milk of the majority of Hungarian mothers, even after the agricultural use of DDT was banned in 1968. No fresh DDT pollution was recognized in the tested samples. Correlations were established among the DDE contents of the breast milk samples and the ages and weights of the tested mothers. The measurements also show the persistency and biomagnificational feature of DDT. The educational aspects of each step of the applied procedures are emphasized in this paper. The analytical processes allow a deep insight for the environmental analysis for environmental engineering students. These offer a manual and theoretical practice with real samples, for improving the environmental attitudes.
