Dioxin pollution in Japan: History and future Dioxin pollution in Contrary to the commonly speculated combustion source as a major pollution source, the study revealed that agrochemicals were the major sources of dioxin in the 1960s and 1970s and still contributing about half of the pollution in the current surface.
INVENTORIES OF DIOXINS AND INVENTORIES OF DIOXINS AND OTHER BY Basic methods for determining emission factors are Measured releases to each medium from individual sources ( bottom up ) per unit of activity; Estimated releases to each medium based on a range of values measured for releases to an entire source.
