An update of the Worldwide Integrated Assessment (WIA) on systemic insecticides. Part 2: impacts on organisms and ecosystems
New information on the lethal and sublethal effects of neonicotinoids and fipronil on organisms is presented in this review, complementing the previous 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, while not much new information has been gathered on soil organisms. The impact on marine 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 classneonicotinoids and fipronil. , withContinued large scale – mostly prophylactic – use of these persistent organochlorine pesticides has the potential to greatly decreasecompletely eliminate 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 (van der Sluijs et al. 2015)
Formação para merendeiras: uma proposta metodológica aplicada em escolas estaduais atendidas pelo programa nacional de alimentação escolar, em Salvador, Bahia Professional training for school lunch cooks: a methodological experiment done in state schools supported by the National School Feeding Program in Salvador, Bahia, Brazil
OBJETIVO: Descrever uma experiência de formação desenvolvida para merendeiras de escolas atendidas pelo Programa Nacional de Alimentação Escolar. MÉTODOS: Trata-se de um estudo descritivo, cujo objeto de análise foi um curso realizado para merendeiras de 97 escolas estaduais, em Salvador (BA). A definição e a implementação da formação apresentou três etapas: sondagem de conteúdos e metodologias junto às merendeiras, desenvolvimento das atividades de formação e avaliação da metodologia do curso pelas merendeiras. RESULTADOS: A consulta às merendeiras possibilitou a indicação dos conteúdos de maior interesse e a metodologia a ser utilizada. O curso teve duração de 20 horas, em turmas de aproximadamente 35 pessoas, e foi realizado em unidades escolares. O programa da atividade apresentou conteúdos diferenciados, incluindo: o Programa Nacional de Alimentação Escolar, a merendeira no sistema da alimentação escolar, princípios de nutrição e alimentação e boas práticas de produção. Como recursos metodológicos foram adotados: teatro, exposição dialogada, oficinas, gincana, experiências práticas, jogos interativos, atividades em grupo, aplicação de formulários e um módulo que contemplava todas as apresentações. Ao final do evento, as merendeiras avaliaram o curso segundo os seguintes aspectos: explicação dos conteúdos, recursos utilizados, ritmo das atividades, atendimento às perguntas, apreensão dos conteúdos, aspectos positivos e negativos e sugestões. CONCLUSÃO: A experiência evidenciou a possibilidade de orientar a construção de um novo modelo de formação, mediante a contribuição e a valorização da consulta ao público-alvo, o que permitiu uma ressignificação das práticas tradicionais de formação e proporcionou maior chance de êxito, devido às demandas específicas apresentadas pelos próprios participantes.<br>OBJECTIVE: This study reports a professional training experiment directed at school lunch cooks in state schools supported by the National School Feeding Program. METHODS: This descriptive study was carried out among school lunch cooks from 97 state schools, in Salvador (Bahia , Brazil). Definition and implementation of the professional training consisted of three stages: a preliminary survey among the cooks in search of contents and methodology, professional training activities and the subjects' assessment of such activities. RESULTS: The preliminary survey pointed to both those contents of major interest among the cooks and the methodology. Professional training activities were designed as a 20-hour event for groups of about 35 people, taking place in school units. The activity program carried a number of different contents, including the National School Feeding Program, the school lunch cooks in the school feeding system, feeding and nutrition principles, and Good Manufacturing Practices. Methodological resources comprised dramatization, dialogued presentations, workshops, group contests, practical activities, interactive games, form completion, guided group activities and a printed brochure with all presentations. At the end of the event, an assessment was requested from the subjects as to the following features: content presentation, resources employed, pace of activities, question answering, content learning, positive and negative aspects as well as suggestions. CONCLUSION: The experiment showed the feasibility of building a new professional training model by using and valuing the contributions from the target subjects, thus allowing the reframing of traditional professional training practices and increasing the chances of success, since the subjects' specific demands were taken into account
