A systematic review was conducted in this study with the aim of analyzing soil salinization in Latin America. Manuscripts published in the region over the past ten years in both English and Spanish that had undergone blind peer review in journals indexed in the databases of Copernicus...

The present study aimed to analyze the linear correlation between the production variables of biofuel based on cocoa (Theobroma cacao L.) mucilage in the city of Calceta - Manabí. The issue addressed was the generation of waste from cocoa farming, leading to contamination of aquifers and the...

Shrimp activity is associated with the impact of bacterial communities. Therefore, this research aimed to evaluate the influence of the bacterial microbiota on the organic matter content of the soil of the shrimp lagoon in La Segua- Ecuador. Starting from a descriptive approach, the field...

The objective of the study was to evaluate the presence of microplastics on San Vicente beach to understand the extent of plastic pollution that currently exists on the beaches. For the quantification and classification of microplastics, the variables were considered: size (> 1 mm and < 4) and color; 10 sampling transects were georeferenced, for extraction a sieve was used to eliminate unwanted particles, while for the water samples the vacuum filtration procedure was used; Finally, the colonization dynamics of microbial Biofilm was carried out in the laboratory. The results indicated the presence of microplastics with a concentration of 16.5 units/kg, with sizes of 1 mm, 2 mm, 2.36 mm and 4 mm, it was evident that the 7 units/kg of microplastics are white in color. (1 mm and 2.36 mm) and 1 unit/kg of blue and white color (2.36 mm and 4 mm). Regarding Biofilm colonization, M3 shows the highest amount with 737 CFU/ml. It is concluded that the study of microplastics on beaches is essential to study the behavior of the ecosystem.

Activated sludge generated by wastewater treatment plants contains high concentrations of pathogenic microorganisms and organic matter, posing a significant environmental challenge. The objective of this research was to achieve sludge stabilization using the Bokashi technique. A completely randomized design (CRD) was employed, comprising four treatments with four replicates each. Treatment 1 (T1) consisted of 35% sludge and 65% Bokashi, Treatment 2 (T2) included 45% sludge and 55% Bokashi, Treatment 3 (T3) comprised 55% sludge and 45% Bokashi, and Treatment 4 (T4) had 65% sludge and 35% Bokashi. Statistical analyses demonstrated that T3 yielded superior results for sludge stabilization, exhibiting optimal parameters, including a moisture content of 46.35%, carbon content of 42.73%, nitrogen content of 1.55%, a pH value of 6.4, and a stabilized temperature range of 30-31 ºC. These findings suggest the potential for efficient alternatives in stabilizing sludge from wastewater treatment plants, making it suitable for agricultural applications.

The purpose of this research was to determine the quality of water for bovine consumption on livestock farms in the El Progreso parish - Galapagos by applying a quality index following the Brown methodology proposed by the National Sanitation Foundation of the United States. Information was collected from the livestock farms through a socio-environmental diagnosis of the area, where five localities were considered: San Joaquín, Las Goteras, Cerro Verde, Puerto Chino and El Progreso from which fifteen livestock farms were selected for the respective sampling of the sources. of water. Therefore, nine parameters were considered for the analysis of the respective water sources: pH, TDS, Fecal Coliforms, electrical conductivity, hardness, nitrites, phosphates, temperature and turbidity. Of the total livestock farms monitored, three of them presented a rating of Good quality in a range of 70 to 90, while the remaining farms recorded values with a Medium classification, which are those that recorded AQI values between 51 to 70 according to the criteria established by the NSF. This research highlights the importance of frequently carrying out analyzes of the water sources from which cattle drink to determine the quality of the resource, and also provide technical advice to ranchers in the area on the management and cleaning of the reservoirs.
