    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-09-15) Liberato, Jamilly Crystini dos Santos; Gomes, Carlos Marcelo Maciel; Lenz, Tiago de Moraes; Lenz, Tiago Moraes; Gomes, Carlos Marcelo Maciel; Barbosa, Ammaury Franklin Benvindo
    This work aimed to analyze the use of pesticides in rice plantations in Ipiranga, a village of Igreja Nova, AL, and the impacts generated in the lives of farmers and the environment. Its methodology was composed of two parts, among them a descriptive qualitative research with the completion of a questionnaire and a field visit, in which interviews were conducted with farmers who cultivate rice. When asked about the use of pesticides and the types applied, 100% of respondents said they use such technology, and all use herbicides, 95% use insecticides and 5% use fungicides. About 74% of the interviewees stated that they receive guidance on the use, and the care that should be taken, and the other 26% stated that they do not. When we asked about the storage and disposal of the packages: for the first, 79% stated that they have a specific place for its storage, 16% stated that they have a shed, but not specific for its storage, and 5% stated that they store them in the back of the house; for the second, 5% stated that the packages are collected by the store where they bought the substances, 32% stated that they are collected by the district, 5% stated that they deliver them to one of the aforementioned, 5% keep these packages, 16% throw them in the conventional garbage, 5% keep them, and 37% incinerate them. Regarding the use of some personal protective equipment (PPE), 74% said they used it and 26% said they did not, the most used being: mask (57%), gloves (43%), long pants and closed (43%), long sleeve shirt (29%), boots (21%), hat (21%), and cape (7%). Of those who did, the most common symptoms were: headache (50%), dizziness (50%), skin irritation (37.5%), nausea (25%), chest pain (25%), sleepiness (25%), decreased vision (12.5%), and pain on one side of the body (12.5%). Regarding damage to the environment, 100% of the farmers said that they did not notice any difference in the local vegetation, in the quantity and variety of animal species, and in the quantity and quality of water. In conclusion, farmers use pesticides in their rice fields, even though they have minimal knowledge about their harmful effects. This work suggests the need for public rural assistance policies to make farmers more aware of the use of pesticides in crops.

    Risco de extinção das abelhas no Brasil: causas, consequencias e soluções
    (2025) Azevedo, Leandro Melo de; Pinheiro, Pablo; Pinheiro, Pablo; Christiano, Daniel; Lenz, Tiago de Moraes
    Bees are essential to maintaining biodiversity and the harmonious functioning of the planet. It is based on this premise that concerns arise about potential threats that may affect them. This paper shows that habitat loss, use of pesticides, diseases, poor nutrition, commercial agriculture, illegal trade in beehives, and light pollution are the main contributors to the advancement of the problem in question. It also presents the possible consequences resulting from the absence of these pollinators, such as the impacts on pollination and agriculture, loss of biodiversity, imbalance in ecosystems, and food and nutritional crises. Finally, the creation and preservation of habitats, regulation and control of pesticide use, monitoring and research on bee health, encouragement of organic agriculture, agroecological practices, environmental education, and public awareness are highlighted as preventive strategies that can be applied in order to circumvent the risk of extinction faced by these insects.
