Immobilization of potentially toxic metals using different soil amendments

The in situ stabilization of potentially toxic metals (PTMs), using various easily available amendments, is cost effective remediation method for contaminated soils. In the present study, we investigated the effectiveness of apatite and commercial mixture of dolomite, diatomite, smectite, bentonite, alginate and zeolite on Pb, Zn, Cd and Cu stabilization by means of decreasing their bioavailability in contaminated soil. We also investigated the impact of apatite and Slovakite applications on soil functionality and quality, as assessed by glucose-induced soil respiration, dehydrogenase, acid and alkaline phosphatase and beta glucosidase activity. Both amendments resulted in increased soil pH and decreased PTM potential bioavailability.

Comparison of efficacy of contact and systemic acting copper formulations for control of apple scab (Venturia inaequalis Cooke)

It was found out that new systemic acting copper formulations can provide comparable rate of apple scab control on fruits as traditional contact acting formulations, therefore application of them can significantly contribute to the reduction of annual cooper rates applied per hectare of orchard.

Validation of the method for the determination of some wine volatile compounds

Volatile compounds were determined with discontinuous liquid-liquid extraction and GC MS detection. It was determined, that the method is linear with square correlation coefficient ranging from 0.961 to 0.999. Limits of quantitative determination range from 0.52 μg/L to 14.8 μg/L. Recoveries range from 71.1% to 105.7% except for two compounds with lower recoveries. Measurement uncertainty ranges from 5.0% to 28.9%. According to the validation, the method is suitable for the determination of at least 24 volatile compounds common to wine. A practical method application was presented on Zelen wine variety from two different production procedures.
