Abstract

The dataset contains the data on the content of three trace elements (copper, zinc, and iron) in samples of honeybees and wild plants collected from 6 farms. The biological samples were collected during the productive season in two periods of the year (T1=April 2023 and T2=July 2023, except for one farm (Farm3 ), for which only the first sampling is present) from 6 farms located in different Italian regions: one from Emilia-Romagna (Farm1), one from Veneto (farm2), one from Friuli Venezia Giulia (Farm6), and three from Abruzzo (Farm3, Farm4, and Farm5). Of the 6 farms, three were conventionally managed (Farm2, Farm4, and Farm6), while the others were organic (Farm1, Farm3, and Farm5). The farms were also grouped into small (Farm1 and Farm2), medium (Farm3 and Farm4), and large (Farm5 and Farm6) according to the number of hives. Trace elements were analysed using atomic absorption spectrometry after acid digestion of the samples.
