Item Avaliação da contaminação por metais pesados em solos urbanos da Região Metropolitana do Recife: bioacessibilidade e correlação com NDVI(2024-03-07) Mello, Lucas José Souza de; Biondi, Caroline Miranda; Lins, Simone Aparecida da Silva; http://lattes.cnpq.br/7329862411748916; http://lattes.cnpq.br/8326756664758702; http://lattes.cnpq.br/8741487779369891Urban pollution by heavy metals is a subject of great socio-environmental relevance due to its potential deleterious effects on human and ecological health. Remote sensing, particularly the use of the Normalized Difference Vegetation Index (NDVI), emerges as a promising tool to assess vegetation health and potential impacts of soil contamination. In this regard, the present study aimed to evaluate the total contents and bioaccessibility of heavy metals in urban soil of the Recife Metropolitan Region and its chemical characteristics, obtain the NDVI of the sampled areas, and correlate it with the total metal contents analyzed. The research was conducted in the Recife Metropolitan Region (RMR), where samples of surface soil were collected in distinct urban areas and their points were georeferenced. The samples were analyzed for pH values, Organic Carbon, Soil Cation Exchange Capacity (CTC), and total heavy metal contents using Energy Dispersive X-ray Fluorescence (pXRF). Metal contents were compared with Quality Reference Values, and in vitro assays were performed to determine metal bioaccessibility in the soil. For NDVI estimation, images obtained from the CBERS-4A satellite with 8m spatial resolution were used, and buffers with radii of 55, 110, and 220m were applied to demarcate the area to be analyzed based on the sampled points. The results revealed high levels of heavy metals in urban areas of the RMR, exceeding the Quality Reference Values for the state of Pernambuco, yet the metals exhibit low bioaccessibility. Regarding the size of the analyzed area, there was no significant difference in relation to the values obtained. Additionally, a negative correlation was observed between most soil metal contents and NDVI, meaning that as NDVI increases, metal contents decrease.Item Eucalipto e biochar para fitoatenuação da poluição do solo por cádmio(2022-10-07) Paraizo, Taciana da Silva; Freitas, Eliane Cristina Sampaio de; Silva, Fernando Bruno Vieira da; http://lattes.cnpq.br/4818569008052606; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/3371289066528888Phytoattenuation is a promising technique to mitigate the deleterious effects of heavy metals toxicity, promoting an environmentally safe management of land use with crops of economic value. The use of biochars can reduce the mobility of metals and provide improvements in soil fertility, promoting safe management in polluted environments. In this sense, the present work aimed to (i) evaluate the immobilization and compartmentalization of Cd in the soil with the application of doses of a filter cake biochar (CB); (ii) assess changes in soil fertility in response to biochar application; (iii) to evaluate the growth, mineral nutrition and Cd accumulation in two eucalyptus species (Corymbia citriodora and the hybrid Eucalyptus urograndis × Eucalyptus urophylla) cultivated in a polluted soil treated with biochar; (iv) to evaluate the amelioration of the stress caused by Cd through the physiological parameters of the plants treated with biochar; and (v) evaluate the regeneration of polluted soil quality through microbiological indicators. Two experiments were carried out sequentially: the first experiment was a sorption assay. The soil was incubated with doses of biochar (0, 2, 4, 8, 12, 16, 24 and 30% m/m) for 64 days and at the end of this period, the availability and chemical fractionation of Cd in the soil were analyzed. and chemical attributes related to soil fertility; the second experiment was carried out in a greenhouse, with two species of eucalyptus grown in pots for 65 days in soil polluted by Cd, with and without the application of 5% CB. After cultivation, the growth parameters were evaluated; the levels of N, P and Cd in the tissues of the plants; chlorophyll a fluorescence parameters and photosynthetic pigments; and biomass together with soil microbial activity. From the results obtained, it was possible to infer that (i) the filter cake biochar can be indicated as a mitigating agent of soil pollution by Cd; (ii) both eucalyptus species associated with the application of 5% BT were tolerant to Cd toxicity; (iii) the cultivation of eucalyptus with the application of biochar promoted improvements in the microbiota of the soil polluted by Cd, a sensitive indicator of environmental quality; and (iv) phytotechnology using the eucalyptus species C. citriodora and the hybrid E. urograndis × E. urophylla plus the application with 5% CB showed potential to attenuate the effects of Cd in polluted areas.Item Uso de espécies florestais na fitorremediação do solo contaminado por cádmio(2019-07-17) Veloso, Aline da Silva; Marangon, Luiz Carlos; Silva, Fernando Bruno Vieira da; http://lattes.cnpq.br/4818569008052606; http://lattes.cnpq.br/6130999923981614; http://lattes.cnpq.br/1011075155653039Cadmium (Cd) contamination of soils represents a potential risk to human and environmental health. The use of forest species as a metal phytoremediator can be an economically and ecologically sustainable choice when associated with silicate fertilization, which will alleviate metal toxicity to plants. In this sense, the study aimed to evaluate: the tolerance of two forest species (Casearia sylvestris Swartz and Machaerium aculeatum Raddi) cultivated in a soil contaminated by Cd and submitted to silicate adduction; bioaccumulation and distribution of Cd and Si, as well as changes in plant nutritional status. The experiment will be carried out in a greenhouse in a completely randomized design in a 2 x 2 factorial arrangement (two forest species: M. aculeatum and C. sylvestris; combined with 0.0 and 200.0 mg kg-1 Si). with three repetitions. The soil used in the experiment was collected at a depth of 0.0 - 0.2 m and characterized chemically and physically. The soils were weighed 9 kg for each pot. Soil contamination was induced with CdCl2.H2O above 10.0 mg kg. Subsequently, they were treated with Si as calcium silicate and then a seedling of each species was transplanted to each pot. The experiment was collected after four months of transplantation. The seedlings were collected and separated in shoots and roots; soil samples were also collected. Soils and plants were extracted and the contents of Cd and Si were determined; In the vegetal tissues the contents of N, P, K, Ca and Mg were determined. The results were submitted to descriptive statistical analysis, ANOVA (one way p <0.05) and Tukey test (p <0.05). The results showed that M. aculeatum presented better tolerance to Cd and when associated with Si obtained higher root biomass and better nutritional status, as well as Si influenced the translocation of Cd to shoot. Although Cd bioaccumulation was more significant in C. syvestris, its development was affected by biomass loss and poorer nutritional status. The distribution of Cd in both species presented the highest concentration in the root. Evaluating the best yield and biomass results, tolerance and nutritional status, M.aculeatum demonstrated potential as a phytostabilizer of cadmium contaminated soil.Item Avaliação quali-quantitativa dos planos de gestão de qualidade ambiental submetidos à Agência Estadual de Meio Ambiente de Pernambuco(2022-05-25) Barbosa, Sandra Dias; Freitas, Eliane Cristina Sampaio de; Souza, Viviannne Lucia Bormann de; http://lattes.cnpq.br/4200588308108261; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/7636706492175339Faced with the needed to conserve biodiversity, actions to recover degraded areas and restore native vegetation are essential to ensure the maintenance and quality of natural resources. The recovering and forest recomposing program demand adequate planning, and in the state of Pernambuco the CPRH Environmental Quality Management Plan exists as an instrument for the control and monitoring of projects that have a polluting potential. The objective of this project was to carry out the evaluation of the Environmental Quality Management Plans - PGQA, in quantitative and qualitative terms, seeking to identify the species and families most indicated in the plans; the risk of species extinction; origin, endemism and distribution. The use of 259 species was identified, comprising 52 families, the most used being the Fabaceae Family. These have an average area of 70,316ha. Having found 23 species in common use among all the plans, with the highest occurrence being Hymenaea courbaril, the extinction analyzes were carried out within the CNCFlora databases where it was identified that 4 species were classified as endangered and IUCN red list where Vochysia oblongifolia and Senna multijuga were identified as endangered. It is worth mentioning that some species were not considered for a risk classification, considering that the absence of this information directly impacts the adoption and implementation of strategies for biodiversity conservation, which may interfere with the quantity and availability in the environment.Item Análise qualitativa de espécies plantadas no bairro da Encruzilhada, Recife-PE(2019-07-15) Nascimento, Isabelly Meg Freitas do; Feliciano, Ana Lícia Patriota; http://lattes.cnpq.br/9184673853412326; http://lattes.cnpq.br/4744657711055499The disorderly growth in urban centers has compromised the quality of life of the population, and the dispute between the environment and the anthropic constructions brought structural problems to the urban environment. The search for the minimization of the impacts caused by this lack of planning is based on the idea of a sustainable environment, which refers to economic growth taking into account the environmental variables, therefore, the urban forestation represents a mean to achieve this objective, and also exercises a primary role in providing physical and psychological benefits to the population. The present study aimed to carry out the qualitative inventory of a planting carried out in 2016 in the neighborhood of Encruzilhada, in the city of Recife-PE. The following qualitative parameters were evaluated: tree name, CAP, phytosanitary status, tree size, height of first bifurcation, canopy status with regard to phytosanitary status and torso status in relation to tortuosity and bifurcation, height total, need for maintenance. The results obtained showed that after three years of planting, only 29% of the individuals planted in the year 2016 were lost, in relation to the species found the following results were obtained: 29,58% Pata de Vaca (Bauhinia monandra Kurz), 26,76% of Resedá (Lagerstroemia indica L), 22,54% of Ipê Branco (roseoalba (Ridl.) Sandwith) and 21,13% of Sabonete (Sapindus saponaria L). Regarding the plant health, 62,94% were in good conditions, 24,48% under regular conditions, 11.89% under bad conditions and 0,70% were dead. In the maintenance needs, 55,30% of the trees need pruning, 25,76% did not require any type of maintenance and 18,94% needed other types of maintenance.
