Abstract: Microplastics are synthetic polymers with sizes from 1 μm to 5 mm, which can be originated from the breakdown of larger plastic materials or even from direct production in industrial processes. MP have become one of the most discussed pollutants in recent years, being ubiquitous in the most diverse environmental compartments, including being reported in marine ecosystems and coastal environments. In these environments, MP vary dynamically in space and time, with the influence of several factors such as tidal fluctuations, seasonal periods, and the physical characteristics of MP themselves such as shape and density. However, MP pollution in estuaries has been poorly reported when taking into account the influence of daily tidal variations that dynamize estuarine environments. Therefore, the objective of this work is to evaluate the dynamics of MP in the waters of the Cocó River estuary (Fortaleza/CE), facing a tidal cycle. The estuary in question is subject to several anthropogenic impacts, such as the discharge of effluents and the disposal of solid waste, which are sources of MP. Water samples from the estuary were collected on May 30, 2022, over a complete tidal cycle, covering ebb and flood periods, under spring tide conditions, in the rainy season. The collection consisted of consecutive trawls every 2 hours, contrary to the direction of the current, using a 120 μm mesh plankton net with attached flowmeter. The collected samples were analyzed in the laboratory, counting on the steps of sieving, digestion of organic material, separation by density, filtration and inspection of the MP under a magnifying glass for counting and identification as to color, shape and size. The results showed that the abundance of MP increased from ebb to flood tide conditions, with mean values of 16.2 items/m3 at ebb and 27.0 items/m3 at flood. Such results may be related to the likely increase in current velocity under flood conditions, which favored the return of PMs that left at ebb, as well as the resuspension of plastic particles previously sedimented and trapped in the intertidal margins. Characteristically, the predominant forms of MP were fibers (53.7%), followed by films (20.8%) and fragments (13.0%), forms associated with the secondary origin of MP. The colors transparent (34.3%), white (20.1%) and blue (18.5%) stood out from the rest. A range of colors was found, possibly due to the complexity of sources around the estuary.

Abstract: In the mangrove of Rio Pacoti a project is being developed to recover the mangrove vegetation in a degraded area previously occupied by a salt marsh near CEAC/LABOMAR. One of the objectives of the project is to analyze how the pioneer herbaceous plants present in the area influence the development of mangrove species there. In this context, the objective of this work was to monitor the presence of Eleocharis spp. in two sample areas: one with the presence of species of the genus Eleocharis and the other considered a control, without the presence of these species. To this end, we defined 10 quadrants of 4 m2 (2 m x 2 m) randomly distributed in each of the patches and in the control areas. The growth rate was compared between the three collections and between the initial and final periods in each area to obtain the relative growth rate (RGR). The salinity of percolated water and soil temperature were measured with the help of a refractometer and a thermometer, respectively. Sediment samples from the two areas were collected at the beginning and end of the experiment to determine the organic matter content. There were 204 individuals of Avicennia germinans in the Eleocharis spp. area, which had a mean height of 67.61 ± 10.22 cm and mean diameter of 1.11 ± 0.32 cm. In the control area, 20 individuals of A. germinans were counted, which had mean height of 76.93 ± 19.49 cm and mean diameter of 1.32 ± 0.35 cm. The average density of A. germinans. in the Eleocharis spp. patch was 10.2 individuals/m2. In the control area, the mean density of A. germinans was 0.33 individuals/m2. The number of individuals differed significantly between areas (t test; p > 0.05), however the height and diameter of individuals did not differ significantly between areas (t test; p < 0.05). The growth rate, in height, of the mangrove specimens in the patch with Eleocharis spp. was 0.85 cm/month and in the control area was 0.073 cm/month. The data suggest that Eleocharis spp. facilitates recruitment and establishment of A. germinans propagules, but does not facilitate growth and diameter.

Abstract: The quest for sustainable consumption has become relevant worldwide, therefore green products are even seen as luxury items, integrated into what is conventionally called green beauty. Given this scenario, this work aims to investigate the reasons why consumers opt for sustainable cosmetics and what are the potential and limitations of these products within the new market. The circular economy is part of this framework of analysis to demonstrate how local green cosmetics producers in Fortaleza foster such an economy, and how these ventures represent a solution to reduce the impacts that the industry causes on the environment. The research was based on a literature review and on the application of forms for consumers (n=100) and producers of green cosmetics (n=4). The results obtained demonstrate that the greatest motivation for purchasing these cosmetics is the search for a sustainable lifestyle, and, at the same time, the greatest limitation for this choice is the users' place of residence. As for the case analysis of producers and their contribution to sustainable consumption, their responses confirmed that micro-entrepreneurs in Fortaleza seek to apply the circular economy in their businesses and that supporting entrepreneurs is essential for the dissemination of this style of economy.

Abstract: The main objective of this research is to study public health from a socio-environmental perspective in the city of Fortaleza. As well as describing the epidemiological and climatic data, verifying whether there is a relationship and influence of climatic variables on the incidence of selected diseases in the population of the city of Fortaleza. The methodology consists of collecting data on four diseases that are present in the daily life of the municipality. Dengue, Leishmaniasis and Leptospirosis data were extracted from the SIMDA Platform and DATASUS for analysis and tabulation. The first part analyzes the general information of each disease, such as the total number of cases by region and by age group, contextualizing it with other social data such as education, HDI, HDI - income and sanitation coverage index. The second part analyzed the data using basic descriptive statistics, and the third part consists of investigating whether the epidemiological and climatic data have a normal distribution, so the Shapiro-Wilk test was used as a reference value. The fourth part consists of using linear regression, to find out if the generated model explains the number of notified epidemiological cases, where the climatic variables are considered independent, while the number of disease cases are the dependent variables. The climatic variables were analyzed individually, to find out if there is any relationship with the epidemiological variables, and subsequently the correlation coefficient was calculated. The last step was to calculate the incidence of the four diseases for the city of Fortaleza, during the selected period. From the survey, it was possible to verify that the regions V and VI, from Fortaleza, presented the highest number of cases of the diseases, at the same time that they presented the lowest social indicators, during the entire period of analysis; while regional II had the lowest number of cases and while it had the highest values of social indicators, the climatic variables showed a weak correlation with the epidemiological variables. With the regression models it was possible to identify the variables that influence the increase or decrease in cases of Dengue, Leishmaniasis and Leptospirosis in the city of Fortaleza. The incidence rate revealed that the city of Fortaleza presents an epidemic of 10 consecutive years of Dengue. Therefore, it is valid to conclude that the population of regions V and VI are the most vulnerable, with this it is necessary to make efforts by the public power to act efficiently and strategically within the territory, seeking a fair, egalitarian society and in the reduction of vulnerabilities.
