Between 1999 and 2020, there were twelve rapid alerts on dioxins in palm fatty acid distillate (PFAD) products, six of which associated with hydrogenated distillates (HPFADs). In oil refineries for food feed, refined PFADs can be processed into HPFADs. This study investigated the effect hydrogenation products contain OCDD impact profiles toxic equivalent (TEQ) level. Palm spiked octachlorodiben...

The authors examined cancer mortality in a historical cohort study of 21,863 male and female workers in 36 cohorts exposed to phenoxy herbicides, chlorophenols, and dioxins in 12 countries. Subjects in this updated and expanded multinational study coordinated by the International Agency for Research on Cancer were followed from 1939 to 1992. Exposure was reconstructed using job records, company...

In animal studies, exposure to dioxins has been associated with disrupted development of the male reproductive system, including testicular maldescent. Some polychlorinated biphenyls (PCBs) have also dioxin-like effects. In addition, one previous case-control study has reported an association between congenital cryptorchidism and colostrum PCB levels. We performed a case-control study to evalua...

BACKGROUND We conducted a population-based human exposure study in response to concerns among the population of Midland and Saginaw counties, Michigan, that discharges by the Dow Chemical Company of dioxin-like compounds into the nearby river and air had led to an increase in residents' body burdens of polychlorinated dibenzofurans (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like...

● Summary ● Introduction ● What are the major sources of dioxin and related compounds in the human diet? ● How do food animals become contaminated with dioxin and related compounds? ● How can dioxin contamination in food animals be decreased? ● Have there been any serious incidents of contamination of food products with dioxins above background levels recently? ● What activities involving dioxi...

 Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (“dioxins”) is a term used to refer to a group of 210 compounds with similar chemical structures  Most of these compounds pose no health hazard at the levels commonly found but 17 of them are of more toxicological concern  The most toxic dioxin is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and most of the available data ...

EXECUTIVE SUMMARY The emission of dioxins is perceived widely as a major environmental impact of combustion processes. This paper reports the results of an extensive study of published data on a) the physical and chemical properties of dioxins and their environmental transport mechanisms; b) the measured impacts of dioxin emissions on the environment and on public health.; c) the rate of format...
