👉 The Delaware fumes, also known as "Delaware haze," refer to a persistent, unpleasant odor that has plagued residents of the Delaware River Valley, particularly in Wilmington and surrounding areas, for decades. This odor is primarily caused by industrial emissions from chemical plants, refineries, and other manufacturing facilities along the Delaware River. The fumes are a complex mixture of volatile organic compounds (VOCs) and sulfur-containing gases, which can linger in the air and water, creating a pervasive, acrid smell often described as reminiscent of burnt rubber, oil, or even decaying matter. Despite efforts to regulate emissions and improve environmental standards, the Delaware fumes continue to affect public health and quality of life for many residents, leading to ongoing debates about industrial regulation and environmental justice in the region.
