Abstract

Beeswax from ten Belgian hives was analyzed for the presence of more than 300 organochlorine
and organophosphorous compounds by LC-MS/MS and GC-MS/MS. Traces of 18 pesticides were
found and not a single sample was free of residues. The number of residues found per sample
ranged from 3 to 13, and the pesticides found could be categorized as i) pesticides solely for
agricultural (crop protection) application, ii) pesticides for mixed agricultural and apicultural
(veterinary) application.
The frequencies and quantities of some environmental pollutants are reason for high concerns.
Most alarming was the detection of lindane (gamma-HCH) and dichlorodiphenyltrichloroethane
(DDT; including its breakdown product dichlorodiphenyldichloroethylene, DDE), two insecticides
that are banned in Europe for several years or even decades. The present comprehensive residue
analysis, however, also reveals residues of pesticides never found in beeswax before, i.e. DEET,
propargite and bromophos
