Conceptual Model: Environmental Pollution on the Arrayanes Bridge

Conceptual Model: Environmental Pollution on the Arrayanes Bridge, Arequipa, Peru 1. Sources of Pollution Vehicular Traffic: Gas emissions (co, Nox, SO2, coVs) from vehicles crossing the bridge. Suspended particles (PM10 y PM2.5) caused by brake wear, tires, and pavement. Fuel and oil spills that can contaminate nearby soils and water bodies. Construction and Maintenance of the Bridge: Particulate matter and other debris generated during bridge construction or maintenance. Chemicals used in bridge preservation, such as paints and solvents. Local Industry and Commercial Activities: Discharges of industrial wastewater that may affect bodies of water near the bridge. Dust and particulate emissions from nearby commercial and industrial activities. 2. Routes and Paths of Exposure to Air: Dispersion of air pollutants such as gases and suspended particles from the bridge to nearby residential and commercial areas. Direct inhalation of pollutants by people who transit or live near the bridge. Water: Surface runoff carrying pollutants from the bridge to the Chili River or nearby streams. Infiltration of contaminants into underground water bodies due to spills or runoff. floor: Deposit of particles and chemicals on the surrounding soil, affecting the quality of soil and plants. Bioaccumulation of heavy metals and other contaminants in vegetation that could enter the food chain. 3. Human Recipients: Local residents: People who live near the bridge and are exposed to pollutants on a long-term basis. Workers and passers-by: Drivers, pedestrians, and cyclists who use the bridge daily. Local ecosystems: Nearby bodies of water: Like the Chili River, that could be affected by pollutants carried by runoff.
