Bromatologia, Facultad de Farmacia, 15706 Santiago de Compostela, La Corufia, Spain Diastase number and hydroxymethylfurfural content were determined for 115 honeys at 4,16, and 28 months after their extraction. The mean values for all samples show linear relations between diastase number and the logarithm of the time and between the logarithm of the hydroxymethylfurfural content and the time. In these honeys, the long-term effects of heat and storage affect the increase in hy- droxymethylfurfural content to a greater degree; however, given the nature of some samples, the diastase number is the limiting factor for freshness in the short term. The factors determining the freshness date of the honeys were also studied and suggestions made for a quality control rule. INTRODUCTION The composition of honey changes with time, which leads to darkening and loss of aroma and flavor. The diastase number

A practical comparison of single and multiple imputation methods to handle complex missing data in air quality datasets

The aim of this work was to evaluate antimony (Sb) as apotentially valuable tracer of the anthropogenic impact on soilsand estuarine sediments. Antimony was determined in fifteenroadsoils from a medium-size city, La Coruna (NW of Spain);and twelve sediments from two estuaries (La Coruna and Ares-Betanzos). Sb determination was accomplished in a rapid andreliable way by directly measuring the solid samples with anautomatic ultrasonic slurry sampling-ETAAS device. Soil contentsranged from 0.29 to 8.81 μg g-1. A relation between Sbconcentration and motor vehicle intensity was observed.Regarding estuarine sediments, Sb amounted from 0.22 to 1.51 μg g-1, for the La Coruna estuary and 0.24 to 0.71 μg g-1, forthe Ares-Betanzos estuary; higher Sb values were found forcoastal locations whereas lower contents corresponded to `inner'samples. In order to confirm these findings, other pollutantswere studied: As, Cd, Co, Cr, Cu, Ni, Pb, Zn, aliphatichydrocarbons (AH) and polycyclic aromatic hydrocarbons (PAH).These values, along with the Sb ones, were subjected tomultivariate studies intended to elucidate whether Sb correlated(and to what extent) to other well-known anthropogenic pollutants. Thus, Sb became associated to Cd, Cu, Pb and Zn in road soils and to As, Cu, Zn, PAH, Pb and unresolved hydrocarbons, in sediments.
