RESUMO: O manguezal é um ecossistema costeiro, presente em diversas partes do mundo, provedor de diversos serviços ecossistêmicos desde a provisão de alimentos a influência das mudanças climáticas. Devido ao desenvolvimento da sociedade, este ecossistema tem sido submetido a significativos impactos proveniente das atividades antropogênicas. Diante disso, o objetivo deste trabalho foi avaliar os impactos ambientais ocasionados em áreas de mangue que sofreram modificações resultantes de atividades antrópicas (cultivo agrícola, desmatamento, construção civil) comparando com área de mangue conservado. Esta pesquisa se deu através da análise da sequência temporal de imagens aéreas (Google Earth), e análise da qualidade do solo mediante coletas em campo para avaliação dos indicadores químicos e biológicos nos diferentes sistemas de uso do solo. Por se tratarem de alterações permanentes e que afetaram o tipo do solo e a cobertura do mesmo, foram obtidas diferenças significativas entre as características químicas e biológicas dos quatro ambientes, com os diferentes sistemas de uso. O manguezal tem sofrido impactos negativos pelo manejo inadequado e ocupação do solo. A continuidade da intervenção antrópica no mangue dará prosseguimento ao desaparecimento deste ecossistema a longo prazo. Dentre os atributos químicos e biológicos utilizados para as análises realizadas, o alumínio e os organismos edáficos foram os que permitiram maior contribuição para descriminação do grau de perturbação das áreas de cultivo agrícola, desmatada e transição construção civil/manguezal.

ABSTRACT: The mangrove is a coastal ecosystem that is present in different parts of the world. It provides various ecosystem services from food supply to the influence of climate change. Due to the development of society, this ecosystem has been subjected to significant impacts from anthropogenic activities. Therefore, the objective of this research was to evaluate the environmental impacts caused in mangrove areas that have undergone modifications as a result of anthropic activities (agricultural cultivation, deforestation, civil construction) compared with those of conserved mangrove areas. This research took place through the analysis of the temporal sequence of aerial images (Google Earth) and soil quality analysis through field collections to evaluate the chemical and biological indicators in the different land use systems. As these are permanent changes that affect the type of soil and its coverage, significant differences were obtained between the chemical and biological characteristics of the four environments, with different usage systems. The mangrove has been negatively impacted by inadequate management and land occupation. Continuity of anthropic intervention in the mangrove will promote the disappearance of this ecosystem in the long term. Among the chemical and biological attributes used for the analyses that were performed, aluminum and edaphic organisms were the ones that allowed the greatest contribution of distinction from the degree of disturbance in areas of agricultural cultivation, deforestation and civil construction/mangrove transition.

The growth of tourism and its infrastructure has led to an increase in the amount of solidwaste, that provoke a negative environmental impact on these destinations. The Francês beach is located in the city of Marechal Deodoro (Brazil) and, despite having a large part of its income concentrated in the tourism sector, no study was carried out to evaluate the perception and management of solid waste generated by tourism in Francês beach. The objective of this paper was to identify the levels of knowledge about solid waste management, as well as the environmental management activities and the environmental perception of the managers of lodging of the French beach in Marechal Deodoro. The research had a qualitative and quantitative character, being carried out interviews with managers of the lodges, application of forms with structured and semistructured questions and the completion of the field diary. The sample had a non-probabilistic character for convenience and for definition of the same were established three criteria: registration in the Ministry of Tourism, means of lodging with a maximum of 30 housing units and interest in participating in the research. After the survey, 21 establishments were able to participate, however, two showed no interest. The forms were applied during the months of July and October 2017. Based on the results obtained, one can affirm that adequate management forms are still evident, because actions such as separation of garbage and training of employees on environmental issues have not yet been carried out for more than 70% of the enterprises surveyed. It is important to highlight that more than 80% of them do not have any policies to minimize the generation of waste in their enterprises. Therefore, there is a real need in the area for works focused on environmental education involving the entire tourism trade, so that a greater awareness of the environment for this sector is created.

El crecimiento del turismo y de la infraestructura turística ha aumentado la cantidad de residuos sólidos, generando un impacto ambiental negativo en los destinos. La Praia do Francês está localizada en el Municipio de Marechal Deodoro (Brasil) y a pesar de que la mayor parte de sus ingresos proviene del sector turístico, no se han evaluado la percepción y el manejo de los residuos sólidos generados por el turismo. Esta investigación busca identificar los niveles de conocimiento sobre la gestión de los residuos sólidos, la gestión ambiental y la percepción ambiental de los gestores de hospedajes en la Praia do Francês. Fue un estudio de carácter cualitativo y cuantitativo, con entrevistas a gestores de los hospedajes y un diario de campo. La muestra no probabilística por conveniencia siguió tres criterios: registro en el Ministerio de Turismo, hospedajes de no más de 30 unidades e interés por participar de la investigación. Los formularios fueron aplicados durante julio y octubre de 2017. Se puede afirmar que la separación de la basura y la capacitación de los empleados sobre temas ambientales, aún no han sido puestas en práctica por más del 70% de los emprendimientos estudiados. Es importante destacar que más del 80% no posee ninguna política para minimizar la generación de residuos en sus emprendimientos. Por lo tanto, existe en el área una necesidad real de trabajos volcados a la educación ambiental que involucren a todo el trade turístico, para despertar mayor consciencia sobre el ambiente en este sector.

Abstract Mangroves are tropical and subtropical flooded forests that generally develop in estuarine areas over unstable sediments protected from the action of waves in the intertidal zone with an environment characterized by a great diversity of fauna and flora. Thus, the present study aimed to evaluate the levels of heavy metals that are absorbed by mangrove oysters, in estuarine systems in the Alagoas coast by determining the concentrations of Fe, Cu, Mn, Zn, Cd and Cr. Two areas, which consisted of both a collection during the rainy season and the dry season, were selected for sampling of mangrove oysters. In each collection, seven samples were collected, at seven different points, where each sample contained four oysters. In the laboratory the oysters were dried at 105°C for 72 hours and then macerated. It was then digested with 10 ml of a solution comprising a combination of 4:1 nitric acid and hydrochloric acid, initially in 1h at 40°C, followed by 3 hours at 140°C. In General, the medians followed the order Zn > Fe > Mn > Cu > Cr > Cd in MMELC and Zn > Cu > Fe > Mn > Cr > Cd in Meirim River. It is concluded that the Crassostrea rhizophorae oysters from the studied environments presented concentrations of all the metals proposed in the research and demonstrates its accumulating and bioindicator character.

A infecção do papilomavírus humano (HPV) é uma das mais freqüentes doenças sexualmente transmissíveis em todo o mundo. A relação entre o HPV genital e oral permanece incerta, assim como o seu papel na carcinogênese oral. O objetivo deste estudo foi verificar a presença do DNA do HPV na mucosa oral e genital de mulheres com infecção genital por HPV, pela técnica de reação em cadeia de polimerase (PCR). FORMA DE ESTUDO: Coorte transversal. MATERIAL E MÉTODO: Trata-se de um estudo piloto, prospectivo, com 30 mulheres, idade de 14 a 51 anos, portadoras de infecção genital por HPV confirmada pelo exame de histopatológico. Todas as pacientes foram submetidas a exame e coleta por raspagem da cavidade oral e genital para pesquisa do DNA do HPV pela técnica PCR. RESULTADOS: Nenhuma das amostras da cavidade oral foi positiva para HPV, enquanto no genital, o HPV foi detectado em 17 (57%) das 30 pacientes, principalmente o HPV 6b e 16. CONCLUSÃO: Os resultados mostraram maior porcentagem do HPV genital em relação à cavidade oral, e sugerem que o HPV genital não parece ser fator predisponente para a infecção oral no mesmo paciente.

Infection by the Human Papilloma Virus (HPV) is one of the most frequent sexually transmitted diseases all over the world. The relationship between oral and genital HPV remains uncertain, as it is with its role on oral carcinogenesis. The goal of the present investigation was to check for the presence of HPV DNA in the oral and genital mucosas of women with HPV genital infection, using the polymerase chain reaction (PCR). STUDY METHOD: Cross-sectional cohort. MATERIALS AND METHODS: this is a pilot and prospective study involving 30 women, aged between 14 and 51 years, with HPV genital infection, confirmed by histopathology. All the patients were submitted to the exam and sample collection by swabbing the oral and genital mucosas in order to test for HPV DNA through the PCR technique. RESULTS: none of the oral cavity samples were positive for HPV, while in the genital tract, HPV was detected in 17 (57%) of the 30 patients, especially HPVs 6b and 16. CONCLUSION: Results show a higher percentage of genital HPV in comparison to the oral cavity, and suggest that genital HPV does not seem to be a predisposing factor for the oral infection in the same patient.
