The history of a chlorpyrifos spill: Cartagena, Colombia
Abstract Due to an operational error, a small amount of chlorpyrifos (an organophosphorus compound) entered the marine bay of Cartegena, Colombia. The resulting fish kill was extensive (17 tons). To hasten the degradation process, the contaminated sediment, the main source of chlorpyrifos to the Bay, was periodically removed. In addition, the exact amount spilled is unknown. Thus, rates of disappearance can only estimated. Under the physical conditions in the Bay of Cartagena, the half-life in water is about 9 days and in fish 11 days. The Bay showed considerable recovery from the biological and chemical effects of the chlorpyrifos spill in 23 days, i.e., chlorpyrifos was below the limits of detection (at or <0.3 μg/L) in the water. During days 3–6 of this study, residue levels in live fish caught were below the level that would cause a human health problem upon their consumption.
