丹江口出现重大国际新闻，看来设立特区 实行直辖 为时不晚

丹江口设立特区8

丹江口：出现重大国际新闻，看来丹江口设立中国特区，实行中央直接管辖，为时不晚！
可以说，名山下出秀水，武当山下丹江口水，山水一体化丹江口设立中国特区，实行中央直接管辖，是时代必行，大势所趋！

从昨天开始，境外媒体包括今天香港南华早报以及联合国其他国际组织，高度关注丹江口，稍后我会详细报道，或者另外单独开帖，希望大家持续关注丹江口设立特区帖子。

Beijing drinking water reservoir found to contain levels of lead '20 times WHO standard'

2015年7月16日 10:52 阅读 22

A major reservoir supplying drinking water to Beijing and many other cities in northern China has been found to contain heavy metal pollutants at levels far above safe standards, according to a new study by mainland Chinese scientists.

Levels of lead in the Danjiangkou reservoir were found to be 20 times the maximum safe level set by the World Health Organisation, at more than 200 micrograms per litre, a 20-fold increase from 2007 to 2010, the researchers found.

The news comes in the same weak researchers in Hong Kong found "excessive" levels of lead in the drinking water of some public housing estates.

The WHO standard for a safe level of lead in a surface water source is 10 micrograms per litre. The maximum level regarded as safe by the United States Environmental Protection Agency is 15 micrograms. China's own national surface water quality standards call for levels to remain under 50 micrograms.

The study, published in the peer reviewed Journal of Environmental Informatics, found that levels of lead in the reservoir outstripped all of these guidelines.

Professor Zhang Quanfa, a researcher with the Chinese Academy of Sciences’ Wuhan Botanical Garden and lead scientist of the long term observation project, declined an interview due to the sensitivity of the issue.

Whether the water from Danjiangkou reservoir was still drinkable “was not a question I am able to answer,” he told the South China Morning Post.

The water from Danjiangkou reservoir, which straddles Henan and Hubei provinces, supplies more than 60 per cent of taps in Beijing, according to the municipal government.

Excessive lead in drinking water can lead to a host of health problems, and can be especially dangerous to infants and children, according to the US EPA.

Lead poisoning can cause delays in physical or mental development with detectable deficits in attention span and learning abilities in children, while in adults the symptoms include kidney problems and increased blood pressure.

It is unclear how the results of the study relate to current drinking water in Beijing. The data collected by the researchers dates back to 2010 and they did not reveal more recent figures.

The water from Danjiangkou also receives extensive treatment at water processing plants before it reaches individual households. The Beijing government said it used advanced technologies and stringent regulations to ensure the quality of drinking water for its residents.

The new study, which collected samples from eight locations across the reservoir, found other kinds of pollutants that exceeded safety standards, including arsenic and chromium, which can lead to cancer and skin problems.

The scientists’ findings contradicted assessments of water quality conducted at Danjiangkou by the Chinese government.

The Ministry of Water Resources said last month that the reservoir had been rated Grade 1, meaning lead levels were below 10 micrograms per litre, for more than 70 per cent of the time it has been in use. Lead levels in the reservoir have never fallen below Grade 2 on the national standards, between 10 and 50 micrograms per litre, the ministry said.

The Danjiangkou reservoir held 29 billion tons of water at the end of 2014 with a surface area of around 450 square kilometres. Its dam was 0.8 km downstream of the junction of the Han and Dan rivers in Hubei and Henan.

By the end of last year the government had spent more than 200 billion yuan on the water diversion project with the main canal exceeding 1,400 km in length.

The South-North Water Transfer Project is designed to funnel more than 14 billion tons of water per year from the Yangtze River region to more than 20 large and medium size cities in the north, with Beijing's water supply given top priority.

“Greater efforts must be made to reduce nitrogen, arsenic and lead pollution for water conservation in the reservoir,” the researchers said in their paper.

They said the increased levels of lead may be caused by an increase in vehicle exhaust pollutants in the upper Han river basin area, as well as mining related activities.

境外媒体以及世界卫生组织公布报告，丹江口水库含铅量严重超标，即超过世界卫生组织20倍，就在昨天，也就是2015-07-18日，从北京传来好消息，丹江口入选中国好水颁奖仪式在北京举行，丹江口又荣获这一国家级殊荣，难道境外媒体报道与丹江口水污染超标有关吗？稍后看微博
