Turkish State Railways
The State Railways of the Republic of Turkey ( tr, Türkiye Cumhuriyeti Devlet Demiryolları), abbreviated as TCDD, is a government-owned national railway company responsible with the ownership and maintenance of railway infrastructure in Turkey, as well as the planning and construction of new lines. TCDD was formed on 4 June 1929 as part of the nationalisation of railways in Turkey. The Turkish State Railways own and maintain all public railways in Turkey. This includes railway stations, ports, bridges and tunnels, yards and maintenance facilities. In 2016, TCDD controlled an active network of of railways, making it the List of countries by rail transport network size, 23rd-largest railway system in the world. Apart from railway infrastructure, TCDD also owns several rail transport companies within Turkey as well as a 50% share of the İzmir-area commuter rail system, İZBAN. Prior to 2017, TCDD also operated all railways in Turkey. However, with the government taking steps to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TCDD Taşımacılık
TCDD Taşımacılık A.Ş. ( en, TCDD Transport, reporting mark TCDDT) is a government-owned railway company responsible for the operations of most passenger and freight rail in Turkey. The company was formed on 14 June 2016, splitting off from the Turkish State Railways (TCDD) to take over railway operations, while TCDD would continue to administer railway infrastructure. TCDD Taşımacılık officially began operations on 1 January 2017. TCDD Taşımacılık operates trains on a network of over within 59 of the 81 provinces in Turkey. Organisation TCDD Taşımacılık is a government-owned company responsible for the operation of passenger and freight railways within Turkey, including logistical centers and train ferries, using infrastructure owned and maintained by the Turkish State Railways. Passenger Operations TCDD Taşımacılık operates passenger rail service on most of its network. Passenger trains service most major cities in Turkey, although a few are without tra ...

2,3,7,8-Tetrachlorodibenzodioxin
2,3,7,8-Tetrachlorodibenzo-''p-''dioxin (TCDD) is a polychlorinated dibenzo''-p-''dioxin (sometimes shortened, though inaccurately, to simply 'dioxin')Tuomisto, Jouko (2019) Dioxins and dioxin-like compounds: toxicity in humans and animals, sources, and behaviour in the environment. WikiJournal of Medicine 6(1): 8 , https://doi.org/10.15347/wjm/2019.008 with the chemical formula CHClO. Pure TCDD is a colorless solid with no distinguishable odor at room temperature. It is usually formed as an unwanted product in burning processes of organic materials or as a side product in organic synthesis. TCDD is the most potent compound ( congener) of its series (polychlorinated dibenzodioxins, known as PCDDs or simply dioxins) and became known as a contaminant in Agent Orange, a herbicide used in the Vietnam War. TCDD was released into the environment in the Seveso disaster. It is a persistent organic pollutant. Mechanism of action TCDD and dioxin-like compounds act via a specific ...

Dioxins And Dioxin-like Compounds
Dioxins and dioxin-like compounds (DLCs) are a group of chemical compounds that are persistent organic pollutants (POPs) in the environment. They are mostly by-products of burning or various industrial processes - or, in case of dioxin-like PCBs and PBBs, unwanted minor components of intentionally produced mixtures. Some of them are highly toxic, but the toxicity among them varies 30,000-fold. They are grouped together because their mechanism of action is the same. They activate the aryl hydrocarbon receptor (AH receptor), albeit with very different binding affinities, leading to high differences in toxicity and other effects. They include: * Polychlorinated dibenzo''-p-''dioxins (PCDDs), or simply dioxins. PCDDs are derivatives of dibenzo''-p-''dioxin. There are 75 PCDD congeners, differing in the number and location of chlorine atoms, and 7 of them are specifically toxic, the most toxic being 2,3,7,8-tetrachlorodibenzodioxin (TCDD). * Polychlorinated dibenzofurans (PCDFs), or ...
