The research realized in La Bóveda in Calceta (Ecuador) with the aim to determine the impact of the agriculture activities in La Bóveda where the quality of the water of run-offs to the reservoir Sixto Durán, to reach the accomplishment´s aim was proceeded to determine the agriculture activities of the community study, realizing topographic, hydrological maps and the use of soil, in addition you poll and cards to corroborate the obtained information, then there was realized the qualities´ valuation water for it there were realized three monitors which are included two in rainy weather and the other in dry one Damming Sixto Durán Ballén). The water quality valuation was done by means the methodology proposed Brown in 1970, which consists of 9 parameters included in Coliformes Fecales, Potential of Hydrogen, Biochemical Lawsuit of Oxygen, Nitrates, Phosphates, Change of Temperature,...

La investigación se realizó en el sitio La Bóveda de la parroquia Calceta (Ecuador) con el objetivo de determinar la incidencia de las actividades agropecuarias del sitio la Bóveda en la calidad del agua de escorrentías al embalse Sixto Durán Ballén, para alcanzar la realización del objetivo se procedió a determinar las actividades agropecuarias de la comunidad en estudio, realizando mapas topográficos, hidrológicos y de uso de suelo, además encuestas y fichas para corroborar la información obtenida, luego se realizó la valoración de la calidad del agua, para ello se realizaron 3 monitoreos los cuales están comprendidos, 2 en época lluviosa (escorrentías) y uno en época seca (Embalse Sixto Durán Ballén), la valoración de la calidad del agua se realizó mediante la metodología propuesta por Brown la cual consta de 9 parámetros comprendidos en coliformes fecales, po...

Evalúa la influencia de la actividad antropogénica en la calidad del agua del embalse La Esperanza, para su uso doméstico y agrícola según las normativas de la OMS y la FAO, para lo cual se realizaron análisis físicos-químicos y microbiológicos, para determinar el estado de eutrofización del Embalse, la calidad del agua cuyos valores fueron interrelacionadas con el indicador (ICA) y preparar un Plan de Buenas Prácticas Agrícola. Escogiéndose cinco puntos de muestreos, correspondientes a las desembocaduras al embalse de los efluentes: Rio Grande, Rio Caña grande y Rio Barro respectivamente y también dos puntos estratégicos en el vaso del embalse georreferenciando estos puntos, muestreando y analizando de acuerdo a protocolos de Standard Methods (2005), Índice de Estados Trófico propuesta por Toledo et al., 1985 y la OCDE 1982; obteniendo como resultado, Según el (IETM) ...

This research focused on the analysis of the ecotoxicological effects of ballast water transported by ships arriving from international trips to the port of Callao on juveniles of Odontesthes regia regia (Pejerrey), through an acute bioassay that determined the mortality of more than 50% of the organisms from the C3 concentration; as well as an evaluation of physicochemical and microbiological parameters that revealed pH values ​​outside the normal range of marine waters with the presence of heterotrophic bacteria in quantities of 210 units. Likewise, the management of the waste that the ships disposed of through naval devices and aquatic reception facilities during the years of 2017 to 2019 in 11 seaports of Peru was evaluated, being the port of Callao the largest receiver with 1,044.95 m3 of mixtures oily and 385.71 t of waste and the port of Chancay the one of lower transfer with ...

The fish oil and flour industry is one of the main productive activities in the country, however, the volumes of organic waste discharged into the marine environment are high. Life Cycle Analysis (LCA) is applied with an emphasis on liquid residues in fishing plants in Huacho, Carquín and Vegueta in Huaura. Lime. The research is applied, descriptive and comparative, it develops a qualitative - quantitative approach. According to ISO 14001, the significant environmental aspects identified include the reception and storage of raw materials, cooking, draining, pressing, separation, centrifugation, grinding, drying, dosing of antioxidant, bagging, energy generation, evaporation of cola water, broth treatment, industrial effluent treatment, machinery maintenance. In the matter and energy balance for a plant of 84 MT / hour, the production yield is fish / flour: 4,150 and for Fish / Oil: 6,30...

ABSTRACT. The objective of this research is to identify the self-purification capacity of the organic matter of the Carrizal River, factors that influence its quality, starting from the point of discharge of wastewater from the oxidation pond in the city of Calceta to the water purification plant "La Estancilla. Several monitoring and analyses were performed, such as flow, pH, temperature, dissolved oxygen and organic matter, using the Protocol for Monitoring Water Resources of Peru, taking 4 points before, during and after the discharge of domestic wastewater, with a sample at a white point as a reference, taken during the low water season of 2019 (September, October and November). For the definition of these points, an information survey of the study area was carried out with ArcGis v10.4.1 software using a georeferenced map with the sampling locations. Organic matter (BOD5) was analyz...
