“…Therefore, the plant species of origin dictates the presence of antioxidant compounds and subsequent bioactive traits, in addition to contaminants such as pesticides and heavy metals (Almeida-Muradian et al, 2005;Campos et al, 2008). Various studies exemplify the use of apiculture biomarkers in the detection of heavy metals (i.e., lead, cadmium, chromium, and nickel), pesticides, and other anthropogenic environmental contaminants, including aromatic hydrocarbons, perfluorinated compounds, and phthalates (Formicki et al, 2013;Gómez-Ramos et al, 2016;Porrini et al, 2003;Tuzen et al, 2007;Üren et al, 1998).…”

E. Mejías, C.J. Gómez, P. Gareil, N. Delaunay, and G. Montenegro. 2018. Characterization of phenolic profile alterations in metal-polluted bee pollen via capillary electrophoresis. Cien. Inv. Agr. 45(1): 51-63. Bee pollen is a conglomerate of plant pollens, and its nutritional contents include bioactive compounds with antioxidant/antiradical potentials. These potentials are conditioned by botanical origin. In Chile, the native flora is diverse and promising in terms of bioactive compounds, but many plants grow in metal-polluted areas. The associated bioaccumulation could negatively affect the antioxidant/antiradical abilities of bee pollen. To assess the relationship between the bioaccumulation of metals and the antioxidant activity of pollen, complete bee pollen was collected near and far from the Llaima Volcano, albeit in ranges that ensured the same botanical origins. Mellisopalynological analysis determined Escallonia rubra pollen was the most abundant native flora in complete bee pollen. Therefore, E. rubra pollen collected near and far from the Llaima Volcano was evaluated for the following: phenolic compounds via colorimetric assays; antioxidant activity via ferric reducing/antioxidant power assays; antiradical activity via 1,1-diphenyl-2-picrylhydrazyl radical assays; and metal contents via inductively coupled plasma optical emission spectrometry. Llaima samples had higher Cu and Fe but lower Mn contents and lower antioxidant and antiradical capacities than did the control samples. These results were supported by subsequent fortification assays in Llaima E. rubra samples. In fortified samples with significantly higher metal contents, antiradical and antioxidant abilities decreased. Moreover, shifts in migration times were found for naringenin, rutine, and caffeic acid after capillary electrophoresis (CE) analysis in fortified samples. In conclusion, the results indicated an inverse correlation between metal contents and antioxidant/ antiradical potentials in bee pollen.

“…In honey harvested in 1984 the average Pb concentration in honey was 0.2 mg/ kg (Bogdanov et al, 1986). In honey harvested (Höffel, 1982;Bogdanov et al, 1986;Uren et al, 1998;Petkov et al, 1998;Fakhim-Zadeh, 1998;Devillers et al, 2002b;Kantonales Laboratorium Basel-Stadt, 2002) 0.02-0.8 blossom (Altmann, 1983;Yazgan et al, 2002) 0.02-0.52 honeydew (Bogdanov et al, 1986;Uren et al, 1998) Contaminants of bee products 3 between 2000 to 2002 it was 0.04 mg/kg (Kantonales Laboratorium Basel-Stadt, 2002). The results, published in different studies show, that lead contamination of honey in polluted and non polluted areas is not significantly different, due to the considerable natural variation of the data (Höffel, 1982;Altmann, 1983;Bogdanov et al, 1986;Jones, 1987;Conti et al, 1998;Yazgan et al, 2002).…”

Contaminants of bee products

2005

-Bee products can be contaminated from different sources. The contamination can arise from beekeeping practices or from the environment. Environmental contaminants are covered in the first part of the review. They are: the heavy metals lead, cadmium and mercury, radioactive isotopes, organic pollutants, pesticides (insecticides, fungicides, herbicides and bactericides), pathogenic bacteria and genetically modified organisms. The second part of the review discusses contaminants from beekeeping. The main ones are acaricides: lipophylic synthetic compounds and non-toxic substances such as organic acids and components of essential oils; and antibiotics used for the control of bee brood diseases, mainly tetracyclines, streptomycine, sulfonamides and chloramphenicol. Other substances used in beekeeping play a minor role: para-dichlorobenzene, used for the control of wax moth and chemical repellents. The degree of contamination of honey, pollen, beeswax, propolis and royal jelly by the different contaminants is reviewed. Honey / beeswax / propolis / royal jelly / contamination / residues

“…Bees fly intensively in a radius of up to 3 km, and for this reason they and their products can serve as bioindicators for the contamination of the area (Bogdanov et al, 2003). A number of authors have used honey bees and/or their products for monitoring environmental pollution (Antonescu and Mateescu, 2001;Devillers et al, 2002;Nanda et al, 2003;Sevimli et al, 1992;Tong et al, 1975;Tüzen, 2002;Uren et al, 1998;Veleminsky et al, 1990). Air and water contain heavy metals from industry and traffic, which can contaminate the bee colonies and their products (Piro and Mutinelli, 2003).…”
