Environmental fate and exposure; neonicotinoids and fipronil
There is strong evidence that soils, waterways, and plants in agricultural environments and neighboring areas are contaminated with variable levels of neonicotinoids or fipronil mixtures and their metabolites, and this provides multiple routes for chronic exposure of nontarget animals. Expand
Systemic insecticides (neonicotinoids and fipronil): trends, uses, mode of action and metabolites
A review of the global literature shows a growing body of evidence that persistent, low concentrations of these insecticides pose serious risks of undesirable environmental impacts and a global evaluation of the potential collateral effects of their use is timely. Expand
Translocation of Neonicotinoid Insecticides from Coated Seeds to Seedling Guttation Drops: A Novel Way of Intoxication for Bees
It is shown that leaf guttation drops of all the corn plants germinated from neonicotinoid-coated seeds contained amounts of insecticide constantly higher than 10mg/1, with maxima up to 100 mg/1 for thiamethoxam and clothianidin, and up to 200 mg/ 1 for imidacloprid. Expand
Assessment of the environmental exposure of honeybees to particulate matter containing neonicotinoid insecticides coming from corn coated seeds.
Experimental results show that the environmental release of particles containing neonicotinoids can produce high exposure levels for bees, with lethal effects compatible with colony losses phenomena observed by beekeepers. Expand
Rapid analysis of neonicotinoid insecticides in guttation drops of corn seedlings obtained from coated seeds.
Current results confirm that the physiological fluids of the corn plant can effectively transfer neonicotinoid insecticides from the seed onto the surface of the leaves, where guttation drops may expose bees and other insects to elevated doses of neurotoxic insecticides. Expand
Aluminium toxicity and metal speciation: established data and open questions
Histopathological findings in humans and extensive toxicological investigation in vivo and in vitro point to an unambiguous neurotoxic potency of AI(III). Experimental toxicology with aqueous AI(III)Expand
An RP-HPLC determination of 5-hydroxymethylfurfural in honey The case of strawberry tree honey.
The bias-free method allows a complete determination of HMF from HA to the baseline level and is faster and more precise than the RP-HPLC official method: the detection and quantification limits are 1.9 and 4.0mgkg(-1), respectively. Expand
Aerial powdering of bees inside mobile cages and the extent of neonicotinoid cloud surrounding corn drillers
A new trial involving mobile cages has been established and consists of making rapid passes with single bees inside cages fixed to an aluminium bar, an innovative biological test to verify the hypothetical efficiency of driller modifications. Expand
Different approaches to the study of chelating agents for iron and aluminium overload pathologies
Aim of this paper is to illustrate the research on different classes of ligands, which are intended as possible chelating agents for the treatment of human pathologies correlated to iron and aluminium overload. Expand
Secondary organic aerosol formation from isoprene photooxidation during cloud condensation–evaporation cycles
The impact of cloud events on isoprene secondary organic aerosol (SOA) formation has been studied from an isoprene / NOx / light system in an atmospheric simulation chamber. It was shown that theExpand
