Original title: Qualität der Bienenprodukte und die Verschmutzungsquellen. Teil 1: Schadstoffe aus Umwelt und Landwirtschaft. Teil 2: Belastung aus der Imkerei. Part 1 considers the possible effects of heavy metals, radioactivity, organic pollutants and pesticides. Levels of residues found in honeys and other hive products vary with the area, levels of atmospheric pollutants are higher in honeydew honeys than in floral honeys. However, values are generally within the permitted limits. Swiss beeswax samples (1994-2000) and 27 honey samples (1997-2001) did not contain detectable levels of 37 organochlorine or 32 organophosphorus pesticides. Part 2 reports on the presence of various acaricides in honey and beeswax comb. In year 2000 the presence of banned antibiotics (against foulbrood) was confirmed in about 6% of Swiss honeys. Para-dichlorobenzene (used against wax moth) was present in 14%of honeys in 1997 and 54% in 2002. It is concluded that contamination of honey and other hive products is mainly due to the use of chemicals in beekeeping.
