Chemical pesticides can present toxic effects to human beings, and they are classified based on chemical characterization, presenting 300 active substances and more than 2000 different formulations. Their overuse can represent a significant risk factor to human health. Therefore, it is essential to investigate the putative association between health harms and pesticides because this information can be helpful for monitoring and controlling pesticide exposure. This study aims to analyze secondary data about pesticides and their effects on genes and disease phenotypes leading to health harm. For this, we used information about pesticides available on the Ministry of Agriculture, Livestock Breeding, and Supply documents. We also use the Set Analyzer tool available on the Comparative Toxicogenomics Database (CTD) to verify a putative association between pesticides and their specific chemical groups to human diseases. Finally, we use variance analysis to evaluate them for statistical purposes. Results showed that 127 chemical groups could be found in food, and they are classified into eight functional classes of pesticides used against pests in food crops. These functional classes are acaricides, bactericides, fungicides, herbicides, insecticides, molluscicides, nematicides, and plant growth regulators. Furthermore, data obtained from the CTD showed a predominance of digestive, nervous, respiratory, and skin diseases as the significant harms caused by pesticide exposure. Results also showed that all the pesticides’ functional classes affect genes associated with cancer development. Considering all the 127 chemical groups, we identified 145321 genes affected by these substances: 49733 genes affected by acaricides, 26832 genes affected by fungicides, 22687 genes affected by herbicides, 42681 genes affected by insecticides, 15842 genes affected by molluscicides, 15842 genes affected by nematicides, and 17217 genes affected by plant growth regulators. Organophosphates are the primary chemical group responsible for genetic effects, mainly leading to cancer and nervous system diseases. So, we conclude that seven different chemical groups can affect genes associated with cancer development and also concluded pesticide use could be related to genes effects and diseases development which can lead to health harms.
A percepção ambiental surgiu como meio de identificar a relação entre os indivíduos e o meio ambiente, buscando verificar as formas como as pessoas percebem o meio ambiente. Dessa forma, o presente estudo visou identificar aspectos relacionados à percepção ambiental de corpos d’água das cidades de Palmeirais-PI e Beneditinos-PI, com o intuito de discutir sobre a frequência, ações de preservação, qualidade da água do rio Parnaíba e do açude Taboquinha, respectivamente. Sendo assim, a pesquisa foi realizada com estudantes de uma escola do município de Palmeirais-PI e cidadãos do município de Beneditinos-PI. Para tal pesquisa, utilizou-se como instrumento de coleta de dados, em ambas as cidades, um questionário estruturado. Diante desse pressuposto, os resultados mostraram que, embora a maioria dos alunos conheçam o rio Parnaíba, desconhecem a ocorrência de ações de prevenção da poluição das águas fomentadas pela escola. Além disso, para os alunos, as atividades de passeio e recreação são as que mais lhes sugerem a utilidade das águas do rio Parnaíba, enquanto uso educativo é quase inexistente. Nesse sentido, observou-se o distanciamento desses alunos de parte de sua realidade local. No que diz respeito aos resultados obtidos com frequentadores do açude Taboquinha, na cidade de Beneditinos-PI, verificou-se a ausência de ações de preservação ambiental, haja vista que os moradores mencionam a má qualidade da água. Assim, concluiu-se que há necessidade de se implantar políticas públicas de conscientização dos frequentadores do açude, a fim de preservar o meio ambiente e ainda assim manter o turismo local. Palavras-chave: Rio Parnaíba. Açude Taboquinha. Percepção ambiental. Educação ambiental. Environmental perception study: different perspectives about water bodies in municipalities in Northeast Brazil Abstract Environmental perception emerged as a means of identifying the relationship between individuals and the environment, seeking to verify the ways in which people perceive the environment. It is also a way to verify the forms as people perceive the environment. This study aims to identify aspects related to the environmental perception of water bodies in the cities of Palmeirais-PI and Beneditinos-PI, in order to discuss the frequency, preservation actions, water quality of the Parnaíba river and the Taboquinha reservoir, respectively. Therefore, the research was carried out with students from a school in the city of Palmeirais-PI and citizens of the city of Beneditinos-PI. For such research, a structured questionnaire was used as a data collection instrument in both cities. Given this assumption, the results showed that, although most students know the Parnaíba River, they are unaware of the occurrence of water pollution prevention actions promoted by the school. In addition, for students, walking and recreation activities are the ones that most suggest the utility of the waters of the Parnaíba River, while educational use is almost non-existent. In this sense, it is observed that these students are distant from part of their local reality. With regard to the results obtained with users of the Taboquinha reservoir, in the city of Beneditinos-PI, there was an absence of environmental preservation actions, given that the residents mention the poor quality of the water. Thus, it was concluded that there is a need to implement public policies to raise awareness among the weir visitors, in order to preserve the environment and still maintain local tourism. Keywords: Parnaíba River. Taboquinha Reservoir. Caatinga.
<p dir="ltr"><span>Atualmente, a utilização de pesticidas químicos em culturas agrícolas tem se tornado cada vez mais frequente. A cafeína é uma das moléculas psicoativas mais consumidas em todo o mundo, no entanto, pouco se sabe sobre as aplicações que ela possui no cenário agrícola. Dessa forma, a presente pesquisa almejou prospectar a utilização da cafeína como um biopesticida em bases nacionais e internacionais de artigos e patentes. Para tal, a busca científica e tecnológica, com palavras-chave e combinações específicas, se deu nas seguintes bases: SciELO, PubMed, INPI, EPO, LATIPAT, USPTO e WIPO. Os resultados para as buscas de artigos e patentes revelaram, de forma geral, que pouco tem sido explorado acerca das atividades biológicas nematicida e larvicida da cafeína. Portanto, conclui-se que novos estudos com a cafeína, voltados para o controle de inimigos naturais de culturas, são promissores para o desenvolvimento de novas tecnologias agrícolas. </span></p><div><span><br /></span></div>
