Cleaning while wearing N respirator, gloves, and goggles View a larger version of this image Avoid breathing in mold or mold spores. In order to limit your exposure to airborne mold, you may want to wear an N respirator, available at many hardware stores and from companies that advertise on the Internet. Some N respirators resemble a paper dust mask with a nozzle on the front, others are made primarily of plastic or rubber and have removable cartridges that trap most of the mold spores from entering.
It is less in length only to the Amazon and Nile, and spans so many regions that it has acquired half a dozen names. Only in the lower reaches does this great flood go by its name common to foreigners: For over two centuries the Yangzte has served as a transportation highway and commercial thoroughfare.
Ocean-going vessels can navigate up the river for km and steamers can travel as far as Yichang, km from the sea.
Other important cities dot the shore of the Yangzte, but perhaps none equal the historic significance, both triumphant and tragic, of Nanjing.
Nanjing has become associated with calamity since the Japanese devastated it in Destruction, mass murder, and torture desecrated this prized city ultimately claimingcivilian lives. The Rape of Nanjing is better forgotten for the Chinese who now trade a great deal with Japan.
The city stands as a symbol of Chinese strength and self-sufficiency, a monument of the people on their great river.
The fertile plains provide one of the most profitable areas of agriculture in China. Rice is the world's single most important food crop and a primary food for more than a third of the world's population. China seeks to provide for its increasing population with improved agricultural technology and increase in fertile land.
The Yangtze provides crucial irrigation to the Jiangsu Province which continues to produce abundant harvests. Winding south and leaving the high country, the river meets the world-renowned Three Great Gorges which tower above it in the western Wu Shan Witch Mountains.
Known in the past for their dramatic beauty as well as religious and historical sites, the Three Gorges have recently received much attention due to the building of the controversial dam.
The perilous Xiling Gorge, furthest down river, often stands shrouded in mists. It threatens weary river vessels with whirlpools, rapids, and water cannons that can easily leave even large watercraft upside down. It is known for its skying walls and the accelerated river beneath them.
The Wu Gorge is tranquil and quiet with a deep valley and twelve peaks along its shores. Qutang Gorge boasts great magnificence in a brief eight-kilometre distance. Traditionally the Yellow River civilisation of the Han culture has received the most attention in research of ancient Chinese history.
Not until recently has the Ba and Chu cultures of the Yangzte River civilisation caught the interest of archaeologists and historians. Serious archaeological work began in China in the s focusing mainly on the Yellow River valley. In the s work reached the more difficult terrain around the Yangtze.
As awareness of the cultural richness of the area has increased, so has the threat of losing it. Chinese archaeologists hurry to examine and explore the historical sites and cultural artefacts along the Yangtze that will be submerged beneath the river once it is dammed. It will create a five trillion gallon reservoir hundreds of feet deep and about miles long, able to absorb an earthquake measuring 7.
In Sun Yat-sen, the father of modern China, originated the idea of a hydroelectric dam in the Three Gorges. Only 23 large and medium scale dams and reservoirs existed in China before Soon after they became commonplace and today China has more than 20, dams over 15 meters high, the most of any country in the world.
While critics of these developments are quick to point out that millions of people have undergone resettlement and dam collapses have caused many fatalities, advocates emphasise that these dams have been a helpful power source and a solution to flooding for the Chinese people.
Nine km long power lines will deliver 18 MWe over several regions. The dam is scheduled to be completed inand as construction continues, objecting voices continue to sir a whirlwind of controversy.
Voiced Complaints In the past few years criticism of the Three Gorges dam has come from many quarters but none so significant and those from within China itself. The government claims that the dam will stop the flooding that killed tens of thousands of people in three major floods in the 20th century.
But some hydrologists counter that the Yangzte sediment and shifting floor of gravel will hinder the turbines and build up in the bottom of reservoir, thereby creating more floods.
Dai Qing, a leading investigative journalist and outspoken critic in China, has called the dam a political project that exhibits the folly of socialist economics.
Like many others, Dai feels that there is no platform to express objections against this project in China. Subsequently Dai was jailed for 10 months and her book was banned.
Others have expressed similar complaints to the project including engineers and academics, but many have kept silent due to the heavy-handedness of the government. In the past, government pressure has been effective in controlling the media and regulating the amount of information exposed to the public.
Much information is still banned from publication within China, but the Chinese media have been able to discover and information that was previously withheld. One example is the dam failures of that devastated the Henan province and claimed overlives but was only recently made known to the public.
And while many still fear to offer public criticism against the government within China, it is notable that Dai Qing has been interviewed by numerous foreign press organisations including the BBC.journal article () Apply journal article filter book chapter () Apply book chapter filter discussion paper () Apply discussion paper filter project paper () Apply project paper filter brief () Apply brief filter report () Apply report filter factsheet () Apply factsheet filter book () Apply book filter working paper () Apply working paper filter.
