Comunidade quilombola no sul brasileiro: identidade, memória e sustentabilidade no Vale do Ribeira Resumo:O presente artigo pretende estabelecer uma reflexão acerca das comunidades quilombolas localizadas no estado do Paraná, em especial a comunidade do João Surá. O processo percorrido nos últimos anos da invisibilidade histórica à emancipação política, contribuiu para o lançamento das bases que vão proporcionar aos comunitários a reconstrução da sua identidade cultural. Mesmo que submetido aos pressupostos da sociedade hegemônica, estes atores sociais irão reforçar as suas práticas sociais como preservação da memória como resistência. Palavras-chave: Identidade; Memória; Sustentabilidade Abstract:This article seeks to establish a reflection on the maroon communities located in the state of Paraná, in particular the community of John Sura. The process covered in the last years of historical invisibility political emancipation, helped to launch the grassroots community that will provide the reconstruction of their cultural identity. Even if subjected to the assumptions of the hegemonic society, these social actors will enhance their social practices as preserving the memory as resistance.
Fresh coconut (Cocos nucifera) water, a popular beverage in tropical countries, is often exposed to pesticide contamination due to agricultural practices. Thus, this work proposed the simultaneous determination of 36 pesticides in fresh coconut water samples using liquid-liquid extraction, drying assisted by a household microwave oven, and gas gas chromatography-mass spectrometry (GC-MS) analysis. Limits of detection varied from 5.4 (disulfoton) to 9.6 ng L-1 (parathion-methyl). Nine pesticides residues were detected (dimethoate, γ-HCH, β-HCH, 4,4’-dichlorodiphenyldichloroethylene, endosulfan II, 4,4’-dichlorodiphenyldichloroethane, 4,4’-dichlorodiphenyltrichloroethane, endrin ketone, and methoxychlor) with concentrations from < limit of quantification to 5,768.34 ± 1.64 ng L-1. Dimethoate was quantified in all samples, indicating its recent use. The proposed methodology offers several advantages, including the use of small sample volumes and solvent extraction, which eliminates the need for costly cartridges and reduces waste production. Additionally, the obtained results can be valuable for regulatory agencies, aiding in the mitigation of environmental damage and the protection of human health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
