BALNEABILITY LÁZARO, DOMINGAS DIAS AND PEREQUÊ-MIRIM BEACHES, MUNICIPALITY OF UBATUBA-SP, COMPARED TO URBAN PHYSICAL AND SOCIO-ENVIRONMENTAL ENVIRONMENTS Lis Lakeis Bertan, Regina de Oliveira Moraes Arruda, Renata Aparecida Costa, Antônio Roberto Saad, Anderson Targino Ferreira, Patricia Bulbovas Hueb Revista De Gestao Social E Ambiental, 2024 Objetivo: O objetivo do estudo foi avaliar os principais fatores que afetam negativamente a balneabilidade de praias localizadas no município de Ubatuba, Litoral Norte do Estado de São Paulo.Referencial Teórico: As condições sanitárias das areias das praias e das águas marinhas destinadas à recreação de contato primário é uma preocupação da saúde pública. Neste contexto, avaliar as condições de balneabilidade das praias, e relacioná-las com o uso do solo, os serviços oferecidos pelo poder público, como esgotamento sanitário e coleta de lixo, e a geomorfologia das praias, é de relevante importância.Método: Para realizar o estudo foram utilizados dados da balneabilidade e dos córregos que afluem ao mar das praias do Perequê-Mirim, Lázaro e Domingas Dias, e realizada a análise da salubridade dessas praias. Mapas foram confeccionados utilizando dados do censo demográfico.Resultados e Conclusões: Os resultados obtidos mostraram que a quantidade de domicílios, tipo de uso desses domicílios, sistema de esgotamento utilizado, condutas de gestão ambiental e as características geomorfológicas são os fatores que afetam negativamente a balneabilidade das praias estudadas.Implicações da Pesquisa: Este estudo avança na compreensão da balneabilidade de praias de importante interesse turístico e pode auxiliar na gestão da qualidade das águas destinas a recreação de contato primário.Originalidade da Pesquisa/Valor: Este estudo se destaca por avaliar os fatores que contribuem para a balneabilidade de praias de importante interesse turístico. Seus resultados podem auxiliar na tomada de decisões do poder público.
Critical analysis of the potential of Psidium guajava cv Paluma (guava tree) for ozone biomonitoring under seasonal subtropical climate Beatriz Barbosa de Souza, Marisa Domingos, Carla Zuliani Sandrin Camargo, Patricia Bulbovas Ecological Indicators, 2022 Psidium guajava cv. Paluma (guava) has been emphasized as good indicator of phytotoxic tropospheric O3 levels in studies conducted under both controlled and field conditions. However, its performance as bioindicator was never critically evaluated under subtropical climate featured by well-defined wet and dry seasons. The current field study provided new contributions on this aspect. Guava cv. Paluma plants were exposed to ozone in several locations of a metropolitan region in SE Brazil - which is featured by well-defined climate seasonality - to collect data to be used to describe seasonal and spatial variations in leaf injury index and in other leaf traits. Multilinear biomonitoring model was also adjusted for different O3 pollution descriptors (daily O3 concentration, AOT40, SUM00 and SUM60), meteorological conditions (air temperature and relative humidity, solar radiation, and vapor pressure deficit) and morphological leaf traits (visible leaf injury, leaf area, leaf dry mass, and leaf mass per leaf area). Visible leaf injuries tended to be higher in locations near the industrial pole. Autumn was the season when guava plants recorded the highest leaf injury caused by O3. Linear regression analysis did not indicate significant association between different O3 descriptors and mean leaf injury; however, multilinear regression analysis has shown that other independent variables increased the bioindicator model’s explicability (R2 = 0.67). Mean leaf injury observed for the 3rd, 4th and 5th oldest guava cv. Paluma leaves were predicted based on combined effects of air temperature and relative humidity, as well as on O3 expressed as AOT40. The other leaf traits were excluded from the multilinear model. The adjusted model was validated as significant tool for future studies about air quality in subtropical regions with seasonal climate.
Soil chemical and physical status in semideciduous atlantic forest fragments affected by atmospheric deposition in central-eastern são paulo state, Brazil MIMS Lopes, A Ribeiro Dos Santos, C Zuliani Sandrin Camargo, P Bulbovas, P Giampaoli, M Domingos Iforest, 2015 The expansion of agricultural, urban and industrial areas in the Sao Paulo State (SE Brazil) led to the fragmentation of the original semideciduous Atlantic Forest into small, patchy forest remnants. Anthropogenic activities produce a variety of pollutants affecting many ecological processes in these remaining forest fragments through soil acidification and fertilization. In this study, we investigated the soil chemical and physical status of six forest remnants (Paulinia, Holambra, Americana, Jaguariuna, Campinas and Cosmopolis) differently affected by industrial, rural and urban pollution in central-eastern Sao Paulo in order to determine the soil potential to buffer the inputs of pollutants. Soil samples from 0-10, 10-20 and 20-40 cm depths were collected in the dry and the wet season and the following variables were analyzed: soil texture, pH in CaCl2 solution, exchangeable cations and exchange capacity, organic carbon, total nitrogen, extractable sulfur, phosphorus and heavy metals. Distinct buffering capacities were observed in industrial and in rural and urban areas, primarily due to the natural characteristics of the soils, such as soil texture, acidification and organic matter. The forest soils affected by atmospheric deposition from the industrial complex (Paulinia and Americana) were more sandy and acidic (pH = 3.6) than those near rural and urban sources (pH = 4.5). The optimal chemical conditions (high contents of organic matter, exchangeable bases, nitrogen, phosphorus and sulfur) were found in the clay soils of forest remnants located in Campinas and Jaguariuna, which were more affected by rural or urban pollution than by industrial emissions. Such clay soils provide the highest buffering capacity against environmental impacts in the study region.
