El presente estudio tuvo como objetivo: Identificar los Aspectos Ambientales Significativos del Mercado Arenales de Ica, 2020. Material y métodos: Investigación básica, descriptiva, no experimental, teniendo como unidad de análisis macro el espacio físico del mercado, y los aspectos ambientales. Se utilizaron técnicas de observación, y análisis in situ, se llevó a cabo en una inmersión inicial y otra definitiva, para recoger los datos, se utilizaron fichas de recolección de datos, bitácora, mapas de sitio y multimedia, y el modelo de la “metodología para la identificación y Evaluación de Aspectos Ambientales de la Universidad Nacional de Colombia”. Resultados: Los factores que normalmente inciden en las condiciones ambientales e higiénicas del Mercado son: Descarga y vertido de aguas residuales, acumulación y control de los residuos sólidos, Instalaciones sanitarias...

In the oxidation ponds, there is an alarming accumulation of sedimentable organic matter, despite the absence of direct tributaries. Although the presence of potentially contaminating elements is suspected, their origin and repercussions still require clarifi cation. It is necessary to determine the organic matter to assess the value of sedimentat ion in this context. Th e study aimed to evaluate the concentration of sedimentable organic matter without effl uent discharge in the Parcona Lagoon, Ica-Peru. Th e Walkley-Black method was used to determine the organic matter in the sediments. After preparing the sample with specifi c reagents, absorbance at 590 nm was measured using a DR-5000 UV-vis spectrophotometer, with reference standards for calibration. A concentration was found at the fi ve sampling points of 3.87; 4.13; 2.96; 3.44; and 2.21 mg/kg, respectively. Th e concentration of o...

The objective of the study was to describe the environmental cost of the biodegradable transformation coefficient in effluents from oxidation ponds, Ica, Peru. In January and February 2023, effluents from the oxidation ponds of Angostura Limón, Yaurilla and Pueblo Nuevo were sampled. Biochemical oxygen demand (BOD5.20) and chemical oxygen demand (COD) were determined where the concentrations were compared with the maximum permissible limit of Supreme Decree 004-2017 MINAM - Peru. With the data, the environmental cost was estimated by a quotient between the cost of assessment (COA) and the regulatory prevention cost (CONP). The values were BOD5.20 = 203.1 mg.L-1 and COD = 405.0 (Angostura Limón), BOD5.20 = 273.1 mg.L-1 and COD = 450.8 mg.L-1 (Yaurilla) and BOD5.20 = 366.5 mg.L-1 and COD = 628.0 mg.L-1 (Pueblo Nuevo). The environmental cost was equal to 0. The BOD5.20 and COD values exce...
