Saúde, Economia e meio ambiente formam um tripé de importante discussão para tomadas de decisões de causa e efeito de cunho político e social. Outrossim, este artigo busca apresentar como as decisões políticas, com participação popular, têm sido edificadas frente a produção de conhecimento da comunidade científica. A interface e o panorama de discussões foram prospectados a nível internacional e nacional, sendo feita a investigação epistemológica da conexão entre economia, saúde e ecologia e como estas são aplicadas pelo poder público, e como este faz a sua avaliação hermenêutica com a ciência pura. Sendo possibilitado acessar que a estruturação política e econômica estão direcionadas a um modelo de investigação centrado no problema, na resultante, de forma desagregada e simplista. Em ampla visão, é perceptível que a produção de conhecimento na vigilância da saúde ainda ocorre de forma muito reducionista e fracionada, sem levar em consideração a diversidade de fatores envolvidos nas questões ambientais, carecendo muitas vezes de uma interdisciplinaridade e sistemática de conhecimentos tão importantes na pesquisa analítica da conexão entre economia, saúde e meio ambiente.

On November 5, 2015, the rupture occurred of the Fundão dam of the mining company Samarco, located in the sub-district of Bento Rodrigues-MG, 35 km from the center of the Brazilian municipality of Mariana-MG, approximately 16.000 Olympic pools of mining residue circulated through the district of Bento Rodrigues in a period of only 11 minutes. The plume of this environmental impact extended approximately 800 km in the Rio Doce basin, between Minas Gerais and Espirito Santo. The Ipiranga river, located between Linhares and São Mateus, was one of the last sites affected by the waste from the Doce river basin, having contact with the sea in the Urussuquara-ES restinga, a place that is a nursery of biodiversity, especially the marine and estuarine ichthyofauna, besides being of great importance for artisanal fishing and ecotourism. The present study aimed to monitor the Ipiranga River and Urussuquara Beach for all seasonal seasons, beginning in September 2017 and ending in May 2018, the following variables were analyzed: dissolved oxygen, electrical conductivity, hydrogenation potential (pH), transparent, temperature, depth and total dissolved solids, comparing them to the Resolution CONAMA n°. 357, de 17/03/2005, with the purpose of evaluating the quality of estuarine and marine waters. The results found were alarming and evident foci of negative impacts on the aquatic ecosystem and society dependent on artisanal fishing for their subsistence.

A investigação multifatorial é uma técnica de análise que pode ser usada simultaneamente para explorar o relacionamento entre inúmeras variáveis alicerçadas em fatores independentes. O procedimento é calcado no exercício epistemológico e no empirismo do observador. Na pesquisa e análise epidemiológica, é ferramenta cabal para o entendimento profundo da história evolutiva de uma doença, donde a doença sempre tem início em ações que geram a degradação ambiental, isto é, a doença é o resultado final de um efeito cascata que tem sua gênese no desequilíbrio ambiental e a sua manutenção por ações deletérias do Estado fundamentado em um modelo econômico neoliberal. A interface e o panorama de discussões deste trabalho científico foi edificado na interdisciplinaridade, tendo base nas ciências políticas, sociais e biológicas, possibilitando assim um esquema de investigação da sinergia e homeostase da doença, outrossim como objeto de estudo foram investigadas as principais doenças tropicais brasileiras e o coronavírus (COVID-19).

The objective of this work was to evaluate the forest restoration of the basin of Guapiaçu river in Cachoeiras de Macacu, Rio de Janeiro state, using the families of Termites as tools for environmental assessment. We analyzed the population fluctuation and feeding guilds of the families of Termites: Kalotermitidae, Rhinotermitidae and Termitidae. Six sampling points were arranged along Guapiaçu river, five points being inferred in reforestation carried out in the basin and a point in a regeneration control area. Quantitative and qualitative surveys followed standard protocols and the samples were obtained directly, without baits. Thirty species within 25 genera were identified and the family Termitidae was the most frequent. The termite fauna of the control point P06 was the richest. From the frequencies of occurrence of the species related to their trophic guild, an ecological evaluation table of the environments was proposed. The P05 area, rich in plant species, presented the greatest similarity to the natural regeneration area P06. The majority of the species was classified as xilophagous.

The Atlantic Forest is the largest biome in the State of São Paulo, one of the most biodiverse ecosystems complexes on the planet, considered a conservation hotspot. This work aimed to list the plant species through the classification of the life forms of RAUNKIAER (1905), improved by CABRERA & WILLINK (1973). The survey of the species was carried out by prospecting’s in 54 quadratic plots of 36 m2, evenly distributed in a forest fragment of 48,010.91 m2. There recorded 97 species distributed in 47 families, with predominance Myrtaceae. The survey was carried out in December 2017, of the total number of species collected in the area of the fragment: 63 are trees, 17 are herbaceous, 6 are epiphytic, 4 are lianas, 3 are shrubs, 2 are palm trees, one is arborescent and one scandent. It is worth noting the registration of the vulnerable species Euterpe edulis, all botanical material is in the Herbarium RBR - UFRRJ - Institute of Biological and Health Sciences.

Hibiscus L. is one of the largest genera of Malvaceae, Southeast Brazil has six endemic species of 14 native species, mainly distributed in cerrado. These Hibiscus are hairy shrubs, with showy flowers of pink corolla, dark base, 5-toothed staminal tube apex, loculicidal capsule of 5 cells. The species inhabit wet ecosystems of the atlantic rainforest and cerrado. After the last study of Hibiscus taxonomy evidencing four endemic species from Minas Gerais state, showed to have the largest endemism center of Hibiscus in Brazil, therefore, using IUCN classification methodology, we indicated H. hilarianus and H. multiformis as vulnerable, H. itirapinensis as endangered and H. mariae as critically endangered. The species are represented by small isolated populations distributed at the mountains and plateaus between Espinhaço mountain range and Planalto Paulista, considered a region with great endemic biodiversity. According to the previously analysis, it is recommended specific studies with techniques and appropriate methodology to research the development and evolutionary characteristics of hibiscus species in Minas Gerais state.

Los niveles de compuestos xenobióticos volcados en los ambientes acuáticos, han aumentado de forma alarmante como resultado de la actividad antropogénica sobre el medio ambiente. Los metales pesados se diferencian de otros compuestos tóxicos por ser absolutamente no degradables, pudiendo acumularse en los componentes del ambiente, como las aguas subterráneas de una región, donde poseen sus concentraciones naturales aumentadas, debido a las actividades antrópicas en los ecosistemas, las aguas subterráneas de regiones en las ciudades, industrias, carreteras, emprendimientos inmobiliarios, garimpos, basurales y viviendas humanas presentan diversas alteraciones en cuanto a las concentraciones permitidas por ley para metales pesados. Para esta realidad ambiental deletérea, la subcuenca del río Estrela, ubicada en el municipio de Duque de Caxias-RJ, tiene uno largo histórico de contaminación por metales pesados, frente a las actividades antrópicas sobre la región. Gran parte de la población local utiliza las aguas subterráneas de la región para consumo humano, animal y en actividades agrícolas, con eso se realizó el sondaje de las aguas subterráneas para evaluar su toxicidad en cuanto a la concentración de metales pesados en referencia a la Resolución No 420/2009 del Consejo Nacional del Medio Ambiente (CONAMA). Para los 18 metales (Aluminio, Arsén, Bario, Boro, Cadmio, Plomo, Cobalto, Cobre, Cromo, Hierro, Manganeso, Molibdeno, Níquel, Selenio, Zinc, Antimonio, Mercurio y Plata) analizados, para un de lineamento muestral de 5 puntos en la subcuenca del río Estrela, se constata una alta concentración de 15 metales potencialmente peligrosos a la salud humana y el bienestar animal y vegetal.

The objective of this work was to evaluate the forest restoration of Guapiaçu river basin in Macacu, RJ, using the families of coleobrocas as tools for environmental assessment. We analyzed the fluctuation of the families of Coleoptera: Cerambycidae, Lyctidae, Anobiidae, Bostrichidae and Curculionidae. Six sampling points were arranged along the river, five points being inferred in reforestation carried out in the basin and a point in the control area of natural regeneration the amount of Guapiaçu river. The collection period started in January 2013, and ended in December 2015. Through quali-quantitative data, there is a greater population density of sub-family Scolytinae in periods of high temperature and humidity and areas more populated by pioneer species used in forest restoration. After the end of the monitoring period, we proposed a model of environmental assessment through the frequency of occurrence of families of coleobrocas collected in forest fragments.
