December 12, 2019 - Concerns have been raised about the potential emission of dioxins from PVC incineration, particularly from municipal waste but also from PVC production plants. However, due to strict regulation and improved production technologies the problem has nearly been eradicated. When an organic substance is incinerated in the presence of chlorinated ...

March 3, 2023 - Dioxins are environmental pollutants and are part of a family of compounds that share distinct chemical structures and characteristics. They are formed when products containing carbon and chlorine burn, especially plastic, paper, pesticides, or other products where chlorine is used in the ...

Gaseous chlorine is poisonous and classified as a pulmonary irritant. It has intermediate water solubility with the capability of causing acute damage to the upper and lower respiratory tract. Chlorine gas has many industrial uses, but it was also once used as a chemical weapon in World War ...

Concerns have been raised about potential emission of dioxins from PVC incineration, particularly from municipal waste but also from PVC production plants. ... When an organic substance is incinerated in the presence of chlorinated compounds, dioxins are generated unintentionally due to incomplete ...

In the October issue of this newsletter, in the article entitled "The Shortage of Credible information on Dioxin," there was a two-paragraph description of a literature review prepared for a March 1990 seminar of the Chlorine Institute, presented by George L.

Dioxins are highly toxic and ubiquitous compounds that are unintentional by-products of several chemical processes on earth. According to the earth po…

Welcome to ETDEWEB World Energy Base (or more simply, ETDEWEB) where you can search and explore literature references and many full text documents not typically available through conventional sources. ETDEWEB is no longer being fully supported as of mid-2014, and there are no new records being ...

Dioxins and dioxin-like compounds are primary examples of persistent organic pollutants that induce toxicity in both wildlife and humans. Over the past 200 years these compounds have been almost exclusively generated by human activity and have left ...

Heterogeneous reactions account for dioxin and furan formation in the post-combustion region. They comprise two reaction pathways: (1) The de novo synthesis, in which the carbonaceous matrix burns with simultaneous oxidation and chlorination. Low oxygen concentrations (less than 2%) may diminish ...

July 20, 2019 - Dioxin are not a building materials or interior products health concern because human exposure overwhelmingly comes from the food we eat.

April 18, 2016 - Chlorine dioxide is one powerhouse sanitizer that is getting more attention recently as food processors look for more efficacious products to help them win the sanitation battle.

Backyard burning of waste materials creates higher levels of dioxins than industrial incinerators and is particularly dangerous because it releases pollutants at the ground level where they are more readily inhaled or incorporated into the food chain.

Dioxins are mainly formed as an unintentional by-product from combustion processes involving organic matter, chlorine compounds and a catalyst, e.g. copper. Formation of trace concentrations of dioxins may take place in any fire or combustion process based on natural or man-made organic materials.

The first reports that it is possible to emit dioxins from the heat and power generation sector are from the beginning of the 1980s. Detailed research proved that the emission of dioxins might occu...

Humans can come into contact with chlorine gas during short-term, high-level exposures due to traffic or rail accidents, spills, or other disasters. By contrast, workplace and public (swimming pools, etc.) exposures are more frequently long-term, low-level ...

Hay, A. Chlorinated dioxins and the environment. Nature 289, 351–352 (1981).

This study examined the concentrations of DRCs including chlorinated, brominated, mixed halogenated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs, PBDD/Fs, PXDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) in surface soil samples from the Agbogbloshie e-waste recycling site in Ghana. PCDD/F and PBDD/F concentrations in open burning ...

December 9, 2024 - Chlorine dioxide is a chemical compound with the formula ClO2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C. It is usually handled as an aqueous solution. It is commonly used as a bleach.
