👉 Spanish fumes, often referred to as "humo español," are a term used to describe a persistent, unpleasant odor that some people experience in regions with high levels of air pollution, particularly in Spain. This odor is typically characterized by a sulfurous, metallic, or chemical smell, often described as reminiscent of old pipes or industrial waste. The source of these fumes is primarily linked to the burning of fossil fuels, especially coal and oil, which is common in certain industrial areas and during specific events like fireworks displays. The phenomenon is not unique to Spain but is notably more pronounced in regions with less stringent environmental regulations, leading to significant public health concerns and occasional protests over air quality issues.
