The El Valle Volcanic Complex, located in the province of Cocle, Panama, presents geological characteristics that could be linked to public health problems. This study focuses on municipalities San Juan de Dios, Pajonal, and Caballero, where water is consumed directly from springs (groundwater outcrops). region has a high incidence non-traditional chronic kidney disease (nt-CKD) may associated with natural presence potentially toxic elements (PTEs) water. aimed analyze concentration PTEs...
The Herrera township (86.0 km2), located in La Chorrera, is Panama’s leading pineapple production area. Ensuring sustainable agricultural management this region crucial for long-term productivity, resource conservation, and environmental protection. This study evaluates soil irrigation water quality to provide insights into improved practices. Soil samples were analyzed pH, EC, OM, SM, CEC, texture, content of Al, Ca, Cu, Fe, K, Mg, Mn, N, P, Si, Sr, Zn. Water samples, including surface...
Mine tailings are a potential source of environmental pollution because they typically contain potentially toxic elements (PTEs) and the residue chemical compounds used during extraction processes. The Remance gold mine (NW Panama) is decommissioned with mining activity records dating from 1800s several periods abandonment. Very little remediation work has been performed, waste exposed to climatic conditions. This study aimed evaluate PTEs cyanide contents in after operations ceased some 20...
The derelict Remance gold mine is a possible source of pollution with potentially toxic elements (PTEs). In the study area, diverse waste has been left behind and exposed to weather conditions, poses risks for soil, plants water bodies, also health local inhabitants. This sought perform an ecological risk assessment mining areas incomplete remediation, including: (i) characterizing geochemical distribution PTEs; (ii) assessing by estimating load index (PLI) potential (RI); (iii) soil...
Los suelos expansivos son característicos de regiones tropicales, presentando grandes cambios volumétricos cuando su contenido agua varía; estos suelen presentar problemas estructurales en las cimentaciones provocados directamente por el comportamiento del material sobre cual han sido construidas. Para controlar la expansión se emplean materiales cementantes, como carbonato calcio (CaCO3), que es un mineral encuentra muchas partes planeta exoesqueletos animales marinos, residuos actividades...
La piña es el segundo cultivo perenne tropical con más importancia a nivel mundial después del banano, aportando 20% volumen total de frutos tropicales. calidad la panameña deleite nacional y mercados internacionales como Europa Estados Unidos, siendo Chorrera mayor productor país. El objetivo este estudio realizar un muestreo geoquímico aplicado labores agrícolas, fin generar mapas geoquímicos pH conductividad eléctrica que sean utilidad producción finca en estudio. se realizó una malla...
Abstract The supply of water to populations is a basic need that has been threatened more frequently in recent years due climate change, which renders seeking other sources essential. hydrochemistry the groundwater aquifer located UTP Tocumen was characterized by previous research determine its possible use as source drinking and irrigation water. objective this study characterize soil rock hosting acquire information about them with view possibly exploit an alternative To end, 10-m-depth...
Abstract: The Remance gold mine, in Veraguas, Panama, has been widely affected by mining activity, whose last exploitation period was between 1989 and 1999, the company Minera S.A. Previous studies have reported that stream sediments are severely polluted; terrace represented a serious ecological risk high presence of concentrations potentially toxic elements (PTEs. In addition, study also showed soil health, evaluated through DHA (dehydrogenase activity) factor, is more than soils....
<p><strong>Abstract</strong></p><p>The Remance gold mine, in Veraguas (central Panama), had its last mining operation 1999, using the cyanidation process for Au separation. As a result of this activity, three waste tailings were exposed to weather, addition mine dumps and open pit areas. Currently area is inhabited by peasants who develop subsistence agriculture livestock. Therefore, objective study has been evaluate...
<p>The inadequate treatment of waste materials in mine tailings, the closure stage not carried out correctly, carries risks due to residues potentially toxic elements (PTEs) that it may contain. In Panama, environmental regulations are recent, and even so strictly enforced, leaving a problem for adjacent communities. Such is case Remance Gold Mine, Veraguas, Panama; this area has been exploited intermittently over hundred years, by different companies; last period exploitation...
Abstract The aim of the present study is to assess combined use geotechnical and electrical geophysical methods determine water quality rocks mechanics in an aquifer. aquifer studied located Tocumen sector Panamá City, southeast city, where there a need possible this provide drinking and/or irrigation based on its quality. To end, 10 m well was perforated sampled characterize host soil rock trough granulometry, Atterberg limits, measure physicochemical parameters perform chemical analysis,...
