La cantidad de residuos sólidos municipales (RSU) generados en la provincia de Lima, capital de Perú, considerada una megaciudad por tener una población de más de 10 millones de habitantes, está aumentando a un ritmo elevado. Lima genera aproximadamente 9 901 toneladas/día de RSU (Municipio de Lima, 2021), y se prevé que aumente con el tiempo debido al crecimiento de la población. Hoy en día este hecho está afectando la infraestructura existente y representa un desafío para los gobiernos locales de Lima, que tienen que disponer sus RSU en otros vertederos fuera de Lima. El estudio investiga las emisiones de metano del relleno sanitario El Zapallal en Lima, Perú, y sugiere posibles estrategias de mitigación para reducir las emisiones de gases de efecto invernadero, destacando el potencial de una reducción del 30% en las emisiones.

The Andes plays an important role in the providing of ecosystem services, however, the greatest threat it faces today is soil contamination by heavy metals, which constitutes a risk in the interaction of man and the environment, in this understanding it is necessary to promote research in the mountainous region in activities that contravene the sustainable development of the region. In this sense, the objective of this study is to evaluate the level of soil contamination by heavy metals by means of the geo-accumulation index and to predict the influence of pH and organic matter on the distribution of metals in the soil. The methodology involved the extraction of four soil samples obtained in an area adjacent to the Paxa stream, where mining waste was dumped; the total concentration of Arsenic, Barium, Cadmium, Copper, Chromium, Lead, Nickel and Zinc was evaluated by the optical emissi...

This article seeks to determine the levels of carbon monoxide (CO) in the air in the busiest streets of modern Lima to which pedestrians are exposed. To measure the concentration of CO, measurements were taken five days a week at three different times of the day, considering the hours with the highest traffic congestion. Also, several factors were considered, such as traffic level, time of day, day of the week, and type of transport. The measurements were taken with a Cheffort portable CO detector, and the results were recorded continuously and in real time to identify if there is a correlation between the factors and the level of this pollutant. As a result, it was determined that there is a direct and statistically significant relationship between the level of traffic and the level of carbon monoxide. In addition, the days with the highest concentration are Fridays with an average of 3...
