👉 The term "baghdad fumes" typically refers to the noxious, sulfurous gases that historically emanated from the ancient city of Baghdad, particularly from the nearby marshes and industrial activities, including coal burning and chemical processes. These fumes are characterized by a strong, acrid smell often described as reminiscent of rotten eggs or sulfur. The pollution was exacerbated by the city's industrial growth and the use of coal in various sectors, leading to significant air quality issues. While modern regulations and cleaner technologies have reduced these emissions, the legacy of historical pollution still lingers, contributing to the persistent odor that has become synonymous with Baghdad's industrial past.
