The objective of this study was to optimize and characterise extraction methods to examine the effects of wood ash application on polycyclic aromatic hydrocarbons (PAHs) concentrations in run-off waters for the evaluation of their distribution by storage in the different compartments (free and bound to dissolved organic matter, DOM), what influence their stability and persistence. The feasibility...
A spectrofluorimetric method for the determination of oxytetracycline (OTC) in medicated feeds and premixes is described. OTC is used alone without combination with other tetracyclines. The method involves sample dissolution in methanol:water (50:50) in the case of medicated premixes, and triple extraction with 1% (w/v) Na 2 .EDTA methanol:water (50:50) in the case of medicated feeds. Determination...
