Summary
The value relations of lead, chromium, nickel and cadmium as detected by automatic monitoring devices and recoderd by chemical analysis from monthly samples of the honey, pollen and larvae of honey bees are reported and discussed. The experiment was conducted at Modena in 1989 using five monitoring stations deployed around the city, each consisting of two hives. No positive correlation between the values for the biological matrices and for the abiological data was found, although there appears to be a certain latency of the pollutant in the former as compared to the latter. In most cases the plotted trends of the data, especially for lead in honey, are overlapping.
