👉 External fumes refer to airborne pollutants and harmful substances that originate from sources outside an enclosed space, such as industrial emissions, vehicle exhaust, chemical spills, or natural occurrences like wildfires. These fumes can include particulate matter (like dust and soot), gases (such as carbon monoxide, sulfur dioxide, and nitrogen oxides), and volatile organic compounds (VOCs). They pose significant health risks, contributing to respiratory issues, cardiovascular diseases, and even cancer when inhaled over prolonged periods. The quality of the air outside can vary greatly depending on factors like weather conditions, urbanization, and industrial activity, making it crucial to monitor and manage external fumes to protect public health and the environment.
