Investigation of PCDD/Fs, Dioxin-Like PCBs and Metal Element in Honey from Taiwan and Mainland China

Abstract

Honey has always been the center of focus, not only because of its valuable nutrition, but also because of its use as an environmental indicator. In this context, 10 honey samples from Taiwan and Mainland China were collected to detect concentration of 17 PCDD/Fs, 12 dioxin-like PCBs and 27 metal elements by HRCG/HRMS and ICP-MS. The main goal was to investigate the difference between honeys of diverse geographical origins and to validate the feasibility of honey being an environmental bioindicator. The result showed lower concentration of PCDD/Fs and dioxin-like PCBs than their MDLs, indicating it was not feasible using honey as the indicator for these compounds in the environment. The result for metal elements showed a higher concentration of K, Na, Mg and Ca in honey from Taiwan than those from the Mainland. Toxic element, As, Ba, Pb, Cd, Cr, Ag, were all found present in honey from the Mainland; while only three of those, Ba, Pb, Cd were detectible in honey from Taiwan. This could imply a much more complex pollution source in the Mainland than in Taiwan

Antioxidant Activities and Heavy Metal Contents of Castanea Sativa Honey

“…Pb has not a beneficial role in human metabolism and can cause health problems (Aghamirlou et al, 2015). The determined Pb content in Sample 3 was lower than the acceptable limits and the following findings in Slovenia (5.94 mg kg -1 ) (Golob et al, 2005), Italy (2.37 mg kg -1 ) (D' Ambrosio and Marchesini, 1982) and was higher than the results from Poland (0.048 mg kg -1 ) (Przybylowski and Wilczynska, 2001), Taiwan and mainland China (0.007-0.029 mg kg -1 ) (Wang et al, 2012).…”

Heavy metals determination in honey samples using inductively coupled plasma-optical emission spectrometry

“…Antonescu and Mateescu [ 44 ] reported that no samples of Rumanian honey contained Cd and As, while it contained lead of 0.1–200 μgkg -1 in the range within the limits imposed by the last regulations of the Codex Alimentarius [ 45 ]. The measured lead concentration was almost higher than those found in honey samples from china (33.98 μgkg −1 ) [ 17 ], Croatia (65.2 μgkg −1 ) [ 4 ], New Zealand (0.017 mgkg −1 ) [ 38 ], Turkey (17.6–32.1 μgkg −1 ) [ 25 ], Poland (0.048 mgkg −1 ) [ 21 ], Romania (0.07 μgkg −1 ) [ 42 ] and in samples from Taiwan and mainland China (0.007–0.029 mgkg −1 ) [ 46 ]. However, the lead concentrations found in this study were lower than those found in honeys from Italian areas (2370 μgkg −1 ) [ 47 ], Slovenia (5.94 mgkg −1 ) [ 20 ] and Italy (620 μgkg −1 ) [ 39 ].…”

Dioxin Analysis of Bee Pollen Pellets Collected by Apis mellifera L. in Rural Area of Turkey

“…Since honeybees travel long distances and come in contact with many plants and also the sources of toxic chemicals in the environment (Kim et al, 2013;Mohr et al, 2014). Although residues of persistent organic pollutants (POPs) have been found in honey samples, such as organochlorine pesticides (Erdogrul, 2007;Wang et al, 2010;Kujawski, Pinteaux, & Namiesnik, 2012), non-dioxin-like polychlorinated biphenyls (ndl-PCBs) (Herrera, 2005;Lie, 2005;Erdogrul, 2007), PCDDs, PCDFs, and dl-PCBs (Wang et al, 2012;Mohr et al, 2014), only one study (Roszko et al, 2016) could have been found for pollen samples on non-dioxin like and dioxin like PCBs. This study aimed to determine the PCDDs, PCDFs, dl-PCBs and ndl-PCBs levels in bee pollen.…”
