Polychlorinated dibenzodioxins (PCDDs), or simply dioxins, are a group of long-lived polyhalogenated organic compounds that are primarily anthropogenic, and contribute toxic, persistent organic pollution in the environment.
Tsing Yi, sometimes referred to as Tsing Yi Island, is an island in the urban area of Hong Kong, to the northwest of Hong Kong Island and south of Tsuen Wan. With an area of 10.69 km2 (4.13 sq mi), the island has been extended drastically by reclamation along almost all its natural shore and the annexation of Nga Ying Chau (牙鷹洲) and Chau Tsai. Three major bays or harbours, Tsing Yi Lagoon, Mun Tsai Tong and Tsing Yi Bay (青衣灣) in the northeast, have been completely reclaimed for new towns.
Yam O is a bay located on the northeast shore of Lantau Island, in the New Territories of Hong Kong. It is part of the Ma Wan constituency of the Tsuen Wan District Council.
Penny's Bay or Chok Ko Wan is a bay in north-eastern Lantau Island, and had been a port since the Ming dynasty. The bay has since been reclaimed and is the site of the Hong Kong Disneyland Resort, which consists of the Hong Kong Disneyland theme park, Disneyland Hotel, and Disney's Hollywood Hotel, and the Inspiration Lake. During the COVID-19 pandemic, it became home to Penny's Bay Quarantine Centre. It is connected by a highway and a rail connection on the MTR Disneyland Resort line to Sunny Bay station.
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. High vapor pressure correlates with a low boiling point, which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility.
Rambler Channel is a body of water in Hong Kong that separates Tsing Yi Island from Tsuen Wan and Kwai Chung in the New Territories. The channel separates the two landmasses by 900 metres at its widest point.
Pillar Island or Tsing Chau was an island in the Kwai Chung area of Hong Kong, sitting at the mouth of Gin Drinkers Bay, by the side of the Rambler Channel, opposite Tsing Yi Island.
Dibenzofuran is a heterocyclic organic compound with the chemical structure shown at right. It is an aromatic compound that has two benzene rings fused to a central furan ring. All the numbered carbon atoms have a hydrogen atom bonded to each of them. It is a volatile white solid that is soluble in nonpolar organic solvents. It is obtained from coal tar, where it exists as a 1% component.
Tsing Yi Lagoon, or Tsing Yi Tong, was a lagoon on the east shore of Tsing Yi Island in Hong Kong. Its water came from a stream in the nearby valley of Liu To and its outlet was at Tsing Yi Bay. It acted as the shelter for nearby boat people, especially after large-scale land reclamation in Tsuen Wan and Kwai Chung. Once their boats moved into the lagoon, they never moved out. This was because their boats were too old for fishing far away. The lagoon was unable to escape the fate of development. Both the lagoon and the neighbouring Tsing Yi Bay, were reclaimed for new towns. The boat people were forced to give up their boats and were relocated to public housing estate on the island. After reclamation, the northern portion became Tsing Yi Estate and the remainder became temporary housing areas, which were later demolished.
Tsing Yi Bay was a bay on the east side of Hong Kong's Tsing Yi Island, beside the Rambler Channel, approximately on the site of modern-day Tsing Yi Park. The whole bay was reclaimed for the development of new town. Before reclamation, it was surrounded by places known as Tsing Leng Tsui, Sheung Ko Tan (上高灘), Ha Chung Mei, Tai Wong Ha and Tsing Yi Town. The names of these places have since changed, and can now be translated, approximately, as Grand Horizon, Green Field Garden, Fung Shue Wo Road, Tsing Yi Estate and Tsing Yi Garden.
Tsing Yi Pier or Tsing Yi Ferry Terminus (青衣渡輪碼頭) was a ferry pier on Tsing Yi Island, Hong Kong. It replaced Tsing Yi Town old pier that was buried during land reclamation. There were ferries to Tsuen Wan and Central. The service ceased to exist and the pier was free for public use thereafter.
Tsing Yi Heung Sze Wui Road is one of the oldest roads on the Tsing Yi Island, Hong Kong. It was built to connect Tsing Yi Town and Tsing Yi Bridge when the bridge was being built. The name "Tsing Yi Heung Sze Wui" derives from the local Cantonese pronunciation of Tsing Yi Rural Committee. After the reclamation of Tsing Yi Lagoon and Tsing Yi Bay, the road ended at Chun Kwan Temple. The office building of the Tsing Yi Rural Committee is very close to the temple, though it is on Fung Shue Wo Road. Tsing Yi Fire Station and Tsing Yi Police Station are also on the road.
Tai Nam Wan, or Nam Wan, was a bay on the south coast of Tsing Yi Island, Hong Kong. The bay was reclaimed for Tsing Yi Power Station operated by China Light and Power. As there is another south bay, Nam Wan (南灣), near Sai Tso Wan to the west of the island, some people refer to this bigger one as big south bay. The Chinese name Nam Wan (南環) is a mistaken form of Nam Wan (南灣). The two characters for Wan in Cantonese are pronounced identically except for the tone.
1,2-Dioxin is a heterocyclic, organic, antiaromatic compound with the chemical formula C4H4O2. It is an isomeric form of 1,4-dioxin (or p-dioxin).
Luk Keng Pier is a small public pier adjoining Luk Keng Village, Yam O, Lantau Island, Hong Kong. There is only a kai-to ferry route to and from Tsing Lung Tau in Tsuen Wan for villagers to travel to the urban area. This closed transportation relationship between Yam O and Tsing Lung Tau explains why Northeast Lantau is part of the Tsuen Wan District, instead of the Islands District. It was the only public transportation for Luk Keng Village and the whole of Yam O before Sunny Bay station on the MTR opened.
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 the case of dioxin-like PCBs and PBBs, unwanted minor components of intentionally produced mixtures.
The American Creosote Works Superfund site is an inactive wood-treating facility in Pensacola, Florida. The 18-acre site is located about 600 yards north of the confluence of Bayou Chico and Pensacola Bay at 701 S "J" Street. The Superfund program of the United States Environmental Protection Agency (EPA) is responsible for cleaning up the nation's most contaminated land and responding to environmental emergencies, oil spills, and natural disasters.
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo-p-dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') with the chemical formula C12H4Cl4O2. 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.
Tin Ka Ping Secondary School is an English medium (EMI) secondary school located in Fanling, Sheung Shui, Hong Kong, founded in 1994. With subsidy from the government, it provides students with various amenities such as practice rooms for extensive arts, audio-visual equipment and sports facilities.
