Abstract
El estudio analizó el impacto ambiental del Complejo Industrial Ventanas (CIV) en el valle de Puchuncaví, considerando elementos traza presentes en el suelo, un biomonitor vegetal (Cupressus macrocarpa) y el material particulado. Los resultados mostraron que las actividades del CIV generan altos niveles de metales pesados como cobre (Cu), plomo (Pb), zinc (Zn) y níquel (Ni) en todas las matrices analizadas. Estas concentraciones superan los estándares internacionales, lo que representa riesgos significativos tanto para el medio ambiente como para la salud humana. El análisis estadístico identificó patrones claros de contaminación vinculados principalmente a actividades antropogénicas, aunque también se observaron aportes de fuentes naturales. Esta situación afecta negativamente la biodiversidad y el bienestar de las personas, subrayando la necesidad urgente de implementar tecnologías para capturar emisiones, desarrollar programas de restauración ambiental y ajustarse a regulaciones internacionales. Además, la relación entre las matrices estudiadas confirmó que comparten fuentes comunes de contaminación. En conclusión, los resultados destacan la importancia de combinar diversas metodologías de análisis para evaluar de manera integral el impacto ambiental y desarrollar estrategias de gestión sostenible para la región.
The study analyzed the environmental impact of the Ventanas Industrial Complex (VIC) in the Puchuncaví valley, considering trace elements present in the soil, a plant biomonitor (Cupressus macrocarpa) and particulate matter. The results showed that VIC activities generate high levels of heavy metals such as copper (Cu), lead (Pb), zinc (Zn) and nickel (Ni) in all the matrices analyzed. These concentrations exceed international standards, posing significant risks to both the environment and human health. The statistical analysis identified clear patterns of contamination linked mainly to human emissions, although contributions from natural sources were also observed. This situation negatively affects biodiversity and human well-being, underscoring the urgent need to implement technologies to capture emissions, develop environmental restoration programs and comply with international regulations. In addition, the relationship between the studied matrices confirmed that they share common sources of pollution. In conclusion, the results highlight the importance of combining diverse analysis methodologies to comprehensively assess environmental impact and develop sustainable management strategies for the region.
