Scientific Opinion on an application by Syngenta (EFSA-GMO-DE-2009-66) for placing on the market of herbicide tolerant and insect resistant maize Bt1…
2015
Question number: EFSA-Q-2009-00444 on request from Competent Authority of Germany; The EFSA GMO Panel previously assessed the four single events combined to produce a four-event stack maize Bt11 × MIR162 × MIR604 × GA21 and did not identify safety concerns. In this opinion, the EFSA GMO Panel assesses the four-event stack maize and all its subcombinations independently of their origin. No new data on the single events, leading to modification of the original conclusions on their safety, were identified. The molecular, agronomic, phenotypic and compositional data on the four-event stack maize did not give rise to safety concerns and there is no reason to expect interactions between the singl…
IPMWORKS, a European network of pionneer farmers engaged to demonstrate cost-effective IPM-based strategies with low pesticide use
2022
Integrated Pest Management (IPM) is based on a diversity of pest management measures(prevention, non-chemical control, best practices for optimizing pesticide efficiency, etc.).These are combined at the farm level to enable reduced reliance on pesticides, and thereforea decrease in the exposure of the environment and people to pesticides. Rare pioneer farmersthroughout Europe are testing such IPM strategies and are succeeding in achieving goodoutcomes with low pesticide inputs. However the majority of European farmers still relyheavily on pesticides, with major environmental and societal impacts, because most of themhave not adopted a comprehensive, farm-level and holistic IPM strategy so f…
Determination of pesticide residues in honey bees, pollen and beeswax: assessing pesticide hazard in spanish apiaries
2020
Pollinator decline is an emerging worldwide problem with serious repercussions on agriculture and environment. Around one third of human food relies on insect pollination, and most of the flowering plants need pollinators to survive. Honey bee is the main pollinator in environments where anthropogenic pressure has reduced the number of native pollinators, like urban, rural and agricultural areas. The main cause of beekeeping crisis is parasite Varroa destructor and secondary infections associated with the mite. Pesticide contamination and nutritional deficiencies, combined with the parasite, can act synergistically and reduce survival of bee colonies. Honey bees patrol extensive areas when …

Risk assessment of exposure to organic chemicals in children and mothers using human biomonitoring
2022
Today, global chemical manufacturing is increasing each year, making environmental pollution and exposure to chemicals a serious public health problem linked to the development of many non-genetic diseases. Approximately, 70 % of chemicals consumed in Europe in 2019 were hazardous for human health. These harmful substances can enter to the food chain and remain in the environment, making humans exposed to them mainly by ingestion, inhalation or dermal exposure. Consequently, exposure to chemicals should be continuously monitored for assuring health protection of citizens by two ways: i) studying their presence in environmental compartments, such as water, food, soil or air, by environmental…

L'exclusion au Moyen Age
2007
1 article en italien, 1 article en castillan traductions en français; Dans ces actes du colloque organisé par le Centre d'Histoire médiévale de l'Université Jean Moulin - Lyon 3, en mai 2005, se trouvent exposées les principales causes de l'exclusion sociale et politique au Moyen Age. Hormis l'hérésie qui n'est pas le sujet de ce colloque, les motifs d'exclusion sont en effet nombreux : mépris des ethnies réprouvées, dégoût ou crainte de la maladie, rejet de la vieillesse, condamnation de la sexualité, ostracisme politique. Les communications insistent sur les méthodes et les marques de l'exclusion : signes distinctifs, ségrégation, relégation, expulsion, injures, recours aux exceptions jur…
Pesticīdu izplatība hidroekosistēmās un to potenciālā ietekme uz ūdens organismiem
2020
Pesticīdu patēriņš pasaulē ir ļoti liels. Pateicoties plašajam pielietojumam pesticīdi nokļūstot hidroekosistēmās, un ir plaši izplatīti vidē. Pesticīdu radītais piesārņojums piesaista pētnieku uzmanību, jo šo pesticīdu darbīgās vielas var būtiski ietekmēt ūdens ekosistēmas un to kvalitāti, sekojoši dzīvnieku un cilvēku veselību. Pētījuma mērķis ir noteikt plaši izplatītu pesticīdu potenciālo ietekmi uz ūdens organismiem. Izmantojot divas biotestēšanas metodes : mikroaļģu augšanas inhibēšanas testu un akūto vēžveidīgo imobilizācijas testu. Papildus biotestēšanai, tika veikta lauksaimnieku aptauju, kuras gaitā tika apkopoti dati par lauksaimnieku izmantotajiem pesticīdiem, to uzglabāšanu un …
Questua, sacrificio e banchetto rituale nelle feste campestri della Sardegna
2019
La questua di denaro, di alimenti e di capi di bestiame, il sacrificio di questi ultimi e il banchetto collettivo sono ancora oggi fra le azioni rituali più importanti delle feste campestri della Sardegna. Attraverso la descrizione e l’analisi di alcuni casi di studio, il contributo si propone di indagare l’importanza del cibo in ambito festivo. Durante il banchetto, infatti, si creano e si rinnovano relazioni e gerarchie, si esalta l’abbondanza e il consumo, si ribadisce l’appartenenza alla comunità e al culto comunitario. Il cibo, in sostanza, diviene un importante e imprescindibile strumento di comunicazione sociale. The begging of money, food and livestock, the sacrifice of the latter a…
Multi-elemental EDXRF mapping of polluted soil from former horticultural land.
2004
The distribution of major and trace elements was systematically investigated by use of energy dispersive X-ray fluorescence spectrometry (EDXRF) on a former horticultural soil. The purpose of the study was to combine mapping of soil element concentration levels with multivariate statistics for characterisation of soil metal pollution in relation to previous and present land use. A 1-ha study site was chosen from a former horticulture where a previous preliminary survey indicated increased concentration levels of toxic elements. The soil was sampled from the top 20 cm of the soil surface in a 10×10-m grid-like pattern covering the 1-ha study area. In addition, three soil profiles were studie…
