01/01/2009 - "Studies on human exposure to PCDD/Fs and the possible effects on hypermineralization of teeth as well as an epidemiological study to reveal increased cancer risk were also conducted. "
01/01/1997 - "Several studies have been conducted to assess the exposure of a cohort of former herbicide-producing workers to PCDD/F and other potential carcinogenic substances and to evaluate the morbidity and mortality, especially for cancer, but also for other causes of death. "
01/15/2013 - "Our results indicated that there was a dose-response relationship between PCDD/F exposure and cancer mortality among foundry workers."
12/01/2012 - "The lifetime excess cancer risks from exposure to PCDD/Fs and PBDD/Fs via inhalation ranged from 0.7 × 10⁻⁵ to 5.4 × 10⁻⁵, or approximately 80 cancer cases in the Taizhou population."

10/01/2008 - "The estimated human intakes of PCDD/Fs originating from pork in the South Korean diet were calculated as 0.029 and 0.019 pg TEQkg(-1) body weight day(-1) for the upper bound exposure in 2002 and 2005, respectively. "
10/01/2006 - "The mean PCDD, PCDF, and DL-PCB intake (total toxic equivalents) via food was estimated 5.34, 3.37, and 2.28 pg World Health Organization (WHO)-TE/kg of body weight (kg-bw) per day for the three age groups 0-6 (breastfeeding excluded), 7-12, and 13-94 years old, respectively. "
08/01/2006 - "For infants of 5 months the chronic exposure to PCDD/F and dioxin-like PCB was 1.1pg WHO-TEQ (toxic equivalents) per kilogram body weight (bw) per day (95th percentile: 1.7pg WHO-TEQ/kg bwxd), which mainly originated from infant formula and vegetables and increased to 2.3pg WHO-TEQ/kg bwxd (95th percentile 3.7pg WHO-TEQ/kg bwxd) for infants just over 1 year old eating the same food as their parents. "
05/01/2006 - "Children receive higher exposures to PCDD/Fs from food than adults on a body-weight basis but those exposures are below the World Health Organization's tolerable daily intake. "

10/16/2012 - "The PCDD/PCDF and PBDD/PBDF emission factors for the burn piles were 50 times higher than those from the burn box likely due to the dominance of smoldering combustion in the burn piles."
09/04/2012 - "To understand the effect of leaf-surface pesticides on emissions of PCDD/F during biomass burns, nine combustion experiments simulating the open burning of biomass were conducted. "
