AIMS To evaluate mortality in New Zealand phenoxy herbicide producers and sprayers exposed to dioxins. METHODS Phenoxy herbicide producers (n = 1025) and sprayers (n = 703) were followed up from 1 January 1969 and 1 January 1973 respectively to 31 December 2000. A total of 813 producers and 699 sprayers were classified as exposed to dioxin and phenoxy herbicides. Standardised mortality ratios...
