Item Atmospheric Aerosols and Air Quality in the 2022 Dry Season in Huancayo-Perú(Universidade Federal do Rio de Janeiro, 2022) Angeles Vasquez, Roberto; Angeles Suazo, Julio Miguel; Abi Karam, Hugo; Flores Rojas, José Luis; Suarez Salas, Luis; Lavado-Meza, Carmencita; Angeles Suazo, Nataly; Boza Ccora, Fernando; De la Cruz-Cerron, Leonel; Zarate Quiñones, RosaThis work presents results of Aerosol Optical Depth (AOD) and Direct Radiative Force (DRF) at the top of the atmosphere (TOA), obtained during monitoring campaigns carried out at the Huancayo Observatory of the Geophysical Institute of Peru (OH-IGP ) in April and August 2022. In these campaigns, a Sun CIMEL photometer was used to measure the microphysical and optical properties of aerosols at wavelengths ranging from 340 to 1020 nm, and a low-cost Purple-air sensor to quantify the concentration of material particulate (PM), in fine and coarse modes. The AOD results indicated values in the range 0.06-0.22. The daily averages of PM2.5 and PM10 did not exceed Peru’s current Environmental Quality Standards (50 μg/m3 and 100 μg/m3 ). The air quality index (AQI) calculated for PM2.5 and PM10 was classified as good. On some days during the campaigns, the air quality was classified as moderate. These results contribute to a better understanding of the current climatic conditions of the Peruvian Altiplano.Item Efecto del material particulado y humedad de suelo en Huancayo y Pampas/Perú(Universidad Pública de El Alto, 2024-12) Angeles Suazo, Julio Miguel; Angeles Vasquez, Roberto; Chavarría Márquez, Esmila Yeime; Lavado-Meza, Carmencita; Huamani Astocaza, Luz Luisa; Cusiche Huamaní, Mery LuzEl material particulado (MP) es un contaminante atmosférico que representa un importante desafío para la calidad del aire en diversas ciudades, entre ellas Huancayo y Pampas, Perú. El objetivo de este artículo es analizar el comportamiento del material particulado y la humedad del suelo en Huancayo y Pampas, Perú. Se centra en la investigación cuantitativa, el estilo de investigación es de carácter descriptivo. La muestra son los datos de material particulado y la humedad del suelo. El diseño fue descriptivo. El resultado fue un estudio teórico experimental sobre la influencia del material particulado (PM2.5) emitido en Pampas y Huancayo, indicando que afecta la calidad del aire y del suelo; concluyendo que las concentraciones promedio de PM10 (20 y 95 ug/m3) y PM2.5 (63 y 100 ug/m3) en Huancayo y Pampas respectivamente; donde de manera fina no se encuentran dentro de los estándares de calidad ambiental.Item Evaluation of the physical-chemical parameters of the Viñas River in Peru(Politechnika Lubelska – Lublin University of Technology, 2024) Chavarría Márquez, Esmila Yeime; Meza Mitma, Pabel Mariano; Lavado-Meza, Carmencita; De la Cruz-Cerrón, Leonel; Angeles Suazo, Nataly; Angeles Suazo, Julio MiguelIn the annex of Viñas, Pampas district, Tayacaja Province, Huancavelica department, Peru, they lack the benefit of a drinking water treatment plant and consume water directly from the river, which is also used for livestock and agricultural activities, and waste is dumped, Therefore, the objective of the study was to analyze the physical-chemical parameters of the Viñas River and compare it with drinking water. The evaluation was performed according to the Jefatural Resolution N° 010-2016-ANA and a Hanna brand multiparameter water analyzer was used to evaluate temperature, total dissolved solids (TDS), dissolved oxygen, conductivity, pH, salinity, biochemical oxygen demand (BOD) and chemical oxygen demand (COD). In addition, ANOVA and Tukey tests, Hierarchical Cluster Analysis and Pearson correlation tests were performed. It was determined that none of the samples analyzed exceeds the ECA for water (DS 004-2017-MINAM), nor LMP (DS 031-2010-SA), in addition, if there are significant differences between samples. On the other hand, the parameters that influence the water quality of the Viñas River are STD (975 mg/L), BOD (58 mg/L) and COD (250 mg/L). It is concluded that the habitants of Viñas consume water according to Peruvian standards, even though it comes directly from the river; therefore, there is a need to improve the water purification systems in the annex.
