“…These concentrations are known to cause at least sublethal effects on bees (Decourtye et al 2005), but increased exposure to imidacloprid presence could not be associated with bee mortality due to the presence of other pesticides. Kasiotis et al (2014) used LC-ESI-MS/MS multiresidue analysis to investigate the presence and concentration of 115 pesticides in dead bees, pollen or honey collected by bees, focusing on pollen and honey collected by individuals or public authorities who evidenced specific high losses or bee death incidents in 2011, 2012, and 2013. Among the analyzed dead bees (n = 44), 50% were positive for clothianidin, 14% for chlorpyrifos, 9% for thiamethoxam, and 4.5% for imidacloprid.…”

New information on the lethal and sublethal effects of neonicotinoids and fipronil on organisms is presented in this review, complementing the previous Worldwide Integrated Assessment (WIA) in 2015. The high toxicity of these systemic insecticides to invertebrates has been confirmed and expanded to include more species and compounds. Most of the recent research has focused on bees and the sublethal and ecological impacts these insecticides have on pollinators. Toxic effects on other invertebrate taxa also covered predatory and parasitoid natural enemies and aquatic arthropods. Little new information has been gathered on soil organisms. The impact on marine and coastal ecosystems is still largely uncharted. The chronic lethality of neonicotinoids to insects and crustaceans, and the strengthened evidence that these chemicals also impair the immune system and reproduction, highlights the dangers of this particular insecticidal class (neonicotinoids and fipronil), with the potential to greatly decrease populations of arthropods in both terrestrial and aquatic environments. Sublethal effects on fish, reptiles, frogs, birds, and mammals are also reported, showing a better understanding of the mechanisms of toxicity of these insecticides in vertebrates and their deleterious impacts on growth, reproduction, and neurobehaviour of most of the species tested. This review concludes with a summary of impacts on the ecosystem services and functioning, particularly on pollination, soil biota, and aquatic invertebrate communities, thus reinforcing the previous WIA conclusions .

Mixture-risk-assessment of pesticide residues in retail polyfloral honey

2016

The presence of even tiny quantities of pesticide residues in honey, a traditional healthy product, is a matter of concern for producers, packers and consumers. This paper aims to quantify pesticides in retail brands of polyfloral honey, and to calculate the mixture risk assessment of honey for consumers according to the results obtained from the analyzed samples. A LC-MS/MS multi-residue method was developed and validated for 13 compounds: 11 pesticides (chlorfenvinphos, coumaphos, tau-fluvalinate, amitraz, which are very common in veterinary treatments, and imidacloprid, acetamiprid, simazine, cyproconazole, tebuconazole, chlorpiryphos-methyl, chlorpiryphos, widely used in agricultural practices), and 2 metabolites of amitraz (2,. Results showed that the samples contained pesticide residues at different concentrations; however, the MRL in honey for each of the 11 pesticides was never exceeded. The most common were amitraz (from 1 to 50 µg/kg) present in 100% of the samples, and coumaphos (up to 14 µg/kg) in 63%. The hazard index (HI) for adults was less than 0.002 in all cases, a long way from 1, the value established as the limit of acceptability.Therefore, commercial honey does not represent any significant risk to health. However, considering that residue levels should be present "as low as reasonably achievable" it is deemed necessary to make an effort to reduce their presence by appropriate agricultural and, above all, beekeeping practices due to acaridae treatments.Keywords: Honey; pesticides; Mixture-risk-assessment; MRL; hazard index 2 IntroductionHoney is a highly valued natural product due to its nutritional properties and appreciated therapeutic applications. However, recently, food alerts caused by the detection of antibiotics, pesticides or heavy metals in honey have jeopardized its healthy image (JuanBorrás et al., 2015). Pesticide residues in honey come from environmental pollution and veterinary practices (Totti et al., 2006;Calatayud-Vernich et al., 2016 , 2016). However, this is the first attempt to apply this approach to retail honey.Therefore, the objective of this paper was to quantify the presence of different pesticides (usually found in the routine control analyses of honey samples) in polyfloral labeled brands, and to estimate the mixture risk assessment of the honey for consumers (due to exposure to pesticides) based on the results obtained from the analyzed samples. As a first step, the analytical procedure was validated in order to guarantee the quality of the results obtained. Material and Methods Honey samplesThis study was carried out with supermarket own-brands and well-known brand honey, which represent almost all of the retail sales in the Spanish market. A total of 22 honey samples, labelled as polyfloral were purchased across Spain from different retail outlets.Samples were purchased with as recent a packing date as possible, based on the label information, and were kept frozen until analysis to minimize losses of target compounds.A mixture of 5 polyfloral honeys w...

Neonicotinoids are systemic insecticides used in agriculture for seed treatment as well as in the pest control by spraying during plant growing. Also, they are found as an active substance in different phytosanitary products used in horticulture for winter spraying in fruit plantations when fruit trees are in vegetative rest. Taking into account the former studies on this topic, knowing all what is published regarding this important theme, both for agriculture and for beekeeping, the review is very important for all interested parts. In the present review many of the questions raised by the beekeepers and the scientists from agriculture receive an answer, together with described methods for identifying and quantifying this class of still used pesticide.
