👉 Existing fumes refer to airborne contaminants released into the atmosphere from various sources, such as industrial processes, vehicle exhaust, and chemical manufacturing. These fumes can include a range of substances like volatile organic compounds (VOCs), particulate matter, carbon monoxide, and heavy metals, which can pose significant health risks when inhaled over prolonged periods. Common sources include factories, construction sites, and even everyday activities like painting or using solvents. The presence of these fumes can lead to respiratory issues, irritation of the eyes and throat, and long-term health problems if exposure is chronic. Proper ventilation and regulatory controls are essential to mitigate their impact on air quality and public health.
