Long-term hazards of polychlorinated dibenzodioxins and polychlorinated dibenzofurans. [PDF]

Environmental Health Perspectives, 1980
During January 10-11, 1978 in Lyon, France, a joint National Institute of Environmental Health Sciences/International Agency for Research on Cancer ad hoc Working Group considered and discussed the feasibility of coordinating epidemiological studies on the long-term hazards associated with the chlorinated dibenzo-p-dioxins and chlorinated dibenzofurans

Quantum Chemical Investigation of Polychlorinated Dibenzodioxins, Dibenzofurans and Biphenyls: Relative Stability and Planarity Analysis

Molecules, 2020
All the possible polychlorinated aromatic compounds in the classes of dibenzodioxins (PCDDs), dibenzofurans (PCDFs), and biphenyls (PCBs) were studied by the quantum chemical methods of HF/6-311++G(d,p), B3LYP/6-311++G(d,p), and MP2/cc-pVTZ.

Environmental contamination of free-range hen with dioxin

Journal of Veterinary Research, 2021
The transfer of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) from a contaminated environment into the food chain is a serious consumer safety problem.

Persistent Halogenated Organic Pollutants in Deep-Water-Deposited Particulates from South China Sea

Toxics, 2023
POP data are limited in the marine environment; thus, this study aimed to investigate background persistent organic pollutant (POP) levels in oceanic deep-water-deposited particulates in the South China Sea (SCS).

Quantifying the importance of the atmospheric sink for polychlorinated dioxins and furans relative to other global loss processes. [PDF]

, 2006
Previous attempts to establish global mass balances for polychlorinated dioxins and furans (PCDD/Fs) have focused on the terrestrial sink, thereby neglecting deposition to the oceans and atmospheric losses.

Comprehensive monitoring of chlorinated aromatic and heteroaromatic pollutants at sites contaminated by chlorine production processes to inform policy making

Emerging Contaminants, 2020
The production of chlorine by the chlor-alkali process using graphite electrodes was one of the largest sources of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDFs) in history with estimates in the kg TEQ range for individual factories. In

Assessment of the feed additive consisting of betaine anhydrous (3a920) for all animal species for the renewal of its authorisation (Genencor International B.V.). [PDF]

EFSA J
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of betaine anhydrous (3a920) as a feed additive for all animal species. In the context of the renewal application, the applicant requested a change of the authorised specifications ...

Placental Markers of Human Exposure to Polychlorinated Biphenyls and Polychlorinated Dibenzofurans [PDF]

Environmental Health Perspectives, 1987
Our studies have evaluated biochemical changes in placentae from humans exposed to rice oil contaminated with polychlorinated biphenyls (PCBs) and polychlorinated dibenzofurans (PCDFs) in Taiwan. Placentae were obtained from nonsmoking women 4 to 5 years after the exposure had occurred. The exposed individuals ingested approximately 1 to 3 g PCBs and 5

Monitoring of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and polychlorinated biphenyls in Estonian food; pp. 193–200 [PDF]

Proceedings of the Estonian Academy of Sciences, 2011
Persistent organic pollutants are mainly compounds that include chlorine, which are posing a threat to human health and impairing living organisms and ecosystems due to their toxicity, persistence, and bioaccumulation.

Time series data (2008–2023) of polychlorinated dibenzo-p-dioxins, dibenzofurans and polychlorinated biphenyls in bivalves from Shellfish Production Areas of the Basque coast (SE Bay of Biscay)

, 2023
The accumulation of contaminants in aquatic organisms is of concern to human health due to the potential for exposure through the consumption of seafood. This dataset presents the levels of 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs),
