Analysis of water quality in Roda D’Água Brook, Uberaba River tributary, MG

Revista Brasileira de Ciência Tecnologia e Inovação (2023)

Larielly Regina Santos Silva Ronielson Gaia da Silva Iara Uliana Moraes Sampaio Danilo Henrique Monteiro Marangoni Thamires Amorim de Sousa

Water resources degradation reflexes the environmental crisis caused by both increased anthropic demands and population growth, which lead to changes in consumption habits, pollution generation and lack of basic sanitation. The cost to treat water for public supply and to recover water springs is high, with emphasis on the relevance of preserving and taking care of water-use procedures. The Water Quality Index (WQI), which assesses waterbodies’ contamination, is the monitoring method adopted in Brazil. The aim of the present study is to assess the quality of water in Roda D’Água Brook, Uberaba City, Minas Gerais State, Brazil, based on WQI. It was done to diagnose this brook’s environmental health. To do so, physical, chemical, and microbiological parameters were assessed. Results have shown that the WQI value recorded for the herein assessed brook is too low, and its water was classified as having very poor quality, since its WQI values were lower than 25 – this number is considered dissatisfactory. Thus, although there was no industrial waste in its water, feces discharge from livestock farms close to this waterbody can be blamed for the frame, given the presence of thermo-tolerant coliforms in the assessed water. Therefore, this water must be avoided for human consumption and for leisure activities; moreover, it is recommended to take migratory actions to reduce anthropic impacts, since the brook’s content is used by the municipal government to water plants in the city. Thus, integrating policies associated with the accountable municipal bureaus are suggested and they must aim at guiding companies and local community, based on environmental policies that exceed the simple development and monitoring of projects focused on mitigating these water-spring issues.

Abiotic dynamics in an area of occurrence of the golden mussel: Limnoperna fortunei (Dunker, 1857), in a stretch of the Rio Grande

Concilium (2023)

Paulo Ricardo da Silva Camargo Afonso Pelli

Physical-chemical parameters can influence the distribution of organisms in space and time. Limnoperna fortunei, a bivalve originating in China, is an example of an organism with high plasticity and wide geographic distribution. A decade after its introduction in the Rio Grande Basin, studies of physicochemical parameters are still scarce. Thus, the objective of this work is to describe the dynamics of physical-chemical parameters in the Lower Rio Grande Basin. For this, the physical-chemical parameters were analyzed: temperature; pH; oxidation potential; Electric conductivity; turbidity; dissolved oxygen and total dissolved solids. A Principal Components Analysis; and a Non-Metric Scaling Analysis were performed. Finally, to verify significant abiotic differences between the points, a comparative analysis was performed. The study demonstrated that even with the effects of seasonality acting on the points, the two stretches of the Lower Rio Grande Basin showed similarity in the abiotic parameters, reflecting environmental stability; what may be positively influencing the population stabilization of Limnoperna fortunei.

FATOR DE CONDIÇÃO DE Melanoides tuberculata (Otto Friedrich Müller, 1774), EM UM TRECHO DO BAIXO RIO GRANDE

Acta Biologica Brasiliensia. (2022)

Luciano Henrique de Paiva João Vitor Sicari Martins Leonardo Ceccacci Lages Álisson Borges Leal Bárbara Cristina Lemos Lucas

Atualmente, uma das principais causas de extinção de espécies é a introdução de espécies exóticas. Melanoides tuberculata é uma espécie de molusco gastrópode tropical e subtropical de água doce, de origem africano-asiática. São prolíficas e generalistas. As populações adaptam-se bem em diversos ambientes aquáticos interiores, incluindo antrópicos. Apresentam distintos atributos, incluindo o fator de condição, que expressa a relação entre uma variável bidimensional e outra tridimensional dos organismos. O fator de condição pode ser utilizado em vários organismos diferentes, como crustáceos, moluscos, peixes, anuros ou mamíferos. O objetivo deste trabalho foi descrever a relação alométrica em Melanoides tuberculata. Foram coletados 90 indivíduos de Melanoides tuberculata. A função que melhor descreveu o fator de condição para Melanoides tuberculata foi a relação da largura das conchas de com seu volume, na função de potência.

ATIVIDADE REPELENTE DE EXTRATOS DE LOURO EM Nauphoeta cinerea (Olivier, 1789)

Acta Biologica Brasiliensia. (2022)

Anna Clara Balbina Silva Afonso Pelli

A procura por plantas medicinais tem crescido devido a seus compostos bioativos, propriedades antimicrobianas e, em particular pelo apelo ecológico. Podem ser alternativas para o controle de diferentes insetos, com a vantagem de serem naturais e, eventualmente, não prejudicarem o ambiente. Objetivou-se com este trabalho avaliar a ação repelente de Laurus nobilis L., sobre Nauphoeta cinerea (Olivier, 1789). Foram utilizados três indivíduos, sendo dois marcados com corretivo líquido à base de água, sendo um com tinta azul e o outro com tinta vermelha. Um terceiro exemplar permaneceu sem marcação. Estes foram mantidos em caixa plástica, cuja tampa foi retirada e colocada um sombrite, o fundo da caixa foi dividido em quadrantes numerados. Foram ofertados alimento e água ad lib. Em um dos quadrantes foi depositada pequena porção de diferentes tipos de extrato vegetal de Laurus nobilis L. Os animais foram acompanhados por um período de duas horas. Os dados apontaram maior eficácia com o uso do vegetal in natura e a seco com o mesmo nível de eficácia em repelência. A utilização de extratos vegetais utilizando Laurus nobilis pode ser uma alternativa na repelência de insetos; não apenas pelo fácil preparo, mas, especialmente quando a meta é a sustentabilidade, quer seja econômica, social e ambiental.

The effect of noise pollution on animal welfare - a case study in balb/c mice

Seven Editora eBooks (2023)

Jaciara Andrade Ramos Karina F. Devienne Afonso Pelli

The quality of life is determined primarily by the quality of the environment. Many variables act on the environment, including noise pollution, present in everyday life. According to the World Health Organization, above 55 db, the body begins to suffer the impact of noise, causing mild stress and excitement. One of the main responses is activation of the hypothalamic-pituitary-adrenal axis, causing the release of glucocorticoids. These hormones act on the energy metabolism, increasing the amount of free fatty acids in the bloodstream. Thus, changes in lipid metabolism have been reported after stressful situations. In this experiment we used Mus musculus balb/c mice submitted to chronic sound stress, at 90dB, for 30 days, at night, from 8 pm to 2 am the next day. The animals were euthanized by decapitation after anesthesia, and the blood collected was used to measure cholesterol, triglycerides, and glucose. During the experiment the animals' weight was monitored, and there was no considerable variation between the control and experimental groups. Regarding the biochemical parameters, there were statistically significant differences in the levels of cholesterol, triglycerides, and glucose. The significance levels, or p values, were 0.067 (p less than 6.7%); 0.053 (p less than 5.3%), and 0.000 (p less than 0.0009%), respectively. With the present study, it can be concluded that stress hormones interfere with cholesterol, triglyceride and glucose metabolism. The chronic noise stress model can be considered a good environmental stress model that mimics urban stress.

Glória Beatriz da Silva Honorato Afonso Pelli

O corrego Gameleira esta situado ao sul do Municipio de Uberaba-MG, com sua nascente proxima a Avenida Filomena Cartafina, passando por varias propriedades e desaguando no rio Grande. Esta sujeito a interferencias antropicas, principalmente pelos efluentes do Distrito Industrial III (DI III) de Uberaba. Visando subsidiar a avaliacao da qualidade de agua, nos meses de maio, agosto e dezembro de 2001, foram realizadas coletas e posterior analise das variaveis, em duas estacoes de coleta: uma antes (Estacao I) e outra apos o corrego Gameleira receber efluentes do DI e III de Uberaba (Estacao II). Nesta pesquisa quantitativa, foram mensuradas as variaveis: temperaturas do ar e agua, condutividade eletrica, turbidez, pH, alcalinidade total, oxigenio dissolvido, demanda bioquimica de oxigenio, fosforo total, nitrogenio total e amoniacal e coliformes fecais; alem da amostragem da comunidade bentonica, com concha de mao, sendo a amostra fixada com formol. Os organismos foram identificados, contados e preservados em alcool 80%. Foram calculados os indices bioticos associando-os a integridade biotica. As aguas da Estacao II apresentaram em relacao a Estacao I, uma elevacao do pH, condutividade eletrica, alcalinidade total, demanda bioquimica de oxigenio, fosforo total, nitrogenio total e amoniacal, coliformes fecais e uma diminuicao do oxigenio dissolvido. O grupo taxonomico mais abundante da comunidade bentonica nas Estacoes I e II foi o Filo Arthropoda, seguido do Annelida e Nematoda. A Ordem que teve uma maior representabilidade foi a Diptera na Estacao I e Coleoptera na Estacao II. Os indices apontaram tendencias de melhores condicoes ambientais para a Estacao I. EVALUATION OF WATER QUALITY IN TWO STRETCH OF GAMELEIRA STREAM, UBERABA/MG, BASED ON PHYSICOCHEMICAL PARAMETERS AND BENTHIC COMMUNITY ABSTRACT Gameleira stream is located in the South of Uberaba in Minas Gerais State, with its source near Filomena Cartafina Avenue. It crosses various properties,flows into the Rio Grande river and is subject to human interferences, mainly by effluent from the III Industrial District (III ID) of Uberaba. Aiming to evaluate water quality sediment and water samples were collected in May, August and December 2001.Physical, chemical, bacteriological analyses and sampling of the benthic community in two stations, one before (Station I) and another (Station II) after Gameleira stream receive effluent of III ID. were carried out. In this quantitative research air and water temperatures, conductivity, turbidity, pH, total alkalinity, dissolved oxygen, biochemical oxygen demand, total phosphorus, total nitrogen and ammonia, and fecal coliforms, as well biotic indices for benthic community were measured through hand dipper sampling. Sample was fixed with formalin. The organisms were identified, counted and preserved in 80% alcohol. Biotic indices were calculated by associating them to biotic integrity. The water of the Station II compared to Station I, showed an increase of pH, electrical conductivity, total alkalinity, biochemical oxygen demand, total phosphorus, total nitrogen and ammonia, fecal coliforms and a decrease in dissolved oxygen during the period of study. The most abundant taxonomic group of the benthic community at Stations I and II was the Phylum Arthropoda, followed by Annelida and Nematoda. The Order that had a greater representability was Diptera and Coleoptera at Station I and II, respectively. The biotic indices showed trends of improved environmental conditions in Station I.

The light intensity in growth, behavior and skin pigmentation of juvenile catfish Lophiosilurus alexandri (Steindachner)

Latin American Journal of Aquatic Research (2019)

Thaís Garcia Santos Marianne Schorer Jose dos Santos Afonso Pelli Marcelo Mattos Pedreira

The survival of several fish species in captivity depends on their adaptation to the environmental conditions and the biological characteristics. The objective of the study was to evaluate the influence of different light intensity levels in growth, behavior and skin pigmentation in juvenile of Lophiosilurus alexandri . Fishes were exposed to the following luminosities: 0, 218, 278, and 459 lux. The experiment was conducted for 75 days, in a water recirculation system with controlled temperatures and aeration. Catfish juvenile were distributed in 35 L aquariums, at the density of 0.28 ind L -1 . In order to evaluate fish growth, weight, standard-total length, weight gain, food consumption, food conversion, biomass, specific growth rate and survival were measured twice times a month. Also, swimming behavior, skin pigmentation and plasma cortisol levels were evaluated. Light influences L. alexandri feed consumption, food conversion, behavior and plasma cortisol levels. Environments with low light are recommended for the L. alexandri growth.
