👉 Fumes are airborne particles or vapors that can be released from various sources, such as industrial processes, vehicle exhaust, and chemical reactions. When these fumes are emitted into the atmosphere, they can travel significant distances before settling on surfaces or being inhaled by people and animals. The term "borders" in this context refers to the edges or limits where these fumes spread, often influenced by wind patterns, topography, and local environmental conditions. In areas with industrial activity or high traffic, fumes can accumulate near borders, such as near factories, highways, or ports, potentially affecting air quality and posing health risks to nearby communities. Effective management of these emissions is crucial to mitigate their impact on public health and the environment.
