英国代写：水对人类的重要性
淡水是地球上维持生命所必需的最重要的元素之一。它是所有人的生命线。水的重要性在于身体需要50%-60%的水。在当今时代，水被用于许多任务，包括灌溉、农业和其他一些事情。除此之外，水还用于许多其他任务。它可以简单地看作是大自然给所有人的礼物。人体需要大量的水。用于饮用的水应该是非常健康的。这是很重要的，因为饮用水应该没有各种杂质。一般来说，供应给人类的水来自管道。这些管道中的水并不完全纯净。因此，确保来自管道的水适合饮用是非常重要的。与水有关的公共场所最重要的问题之一是水含铅问题。这种铅很容易进入水中，对人的生命非常有害。此外，一些化学废水也污染水。它是另一种危险的水污染物(世界卫生组织，2004)。化学水污染可能包括一些化学废水，如来自工业的金属和溶剂。这些化学品是有毒的，如果服用，可能是有害的。此外，农药是另一种可能污染水的有害化学物质。另一种污染物是生物膜。它是在一个表面收集无机、有机和无机、活的或死的材料(世界卫生组织，2003)。由于饮用水管道中的生物膜，存在着许多问题。这些可能会导致一些问题，如细菌水平的增加，味道和气味的变化，红色和黑色的水的问题。
人类对健康生活的追求近三十年来，香港的经济发展和人民的知识水平不断提高。80年代，香港发展迅速。信息通信技术也得到了长足的发展，特别是互联网已经发展成熟。这个地方被改变了从一个工业现代商业城市(Misiūnas, 2008)。随着经济条件的改善，人们开始追求更加奢侈的生活方式。通过经济发展的优势，人们可以提高他们的知识，拓宽他们的视野。在这种情况下，人们会从不同的渠道学习和发现新的信息。与此同时，人们会更关注他们的健康或关注改善他们的生活质量。
公共租住房屋是解决香港居民生活问题的最重要的房屋政策。众所周知，这个小城市人口密度很高。高层实用的政府补贴租赁住宅楼可以容纳720户家庭和3000人(Tamminen et al.， 2008)。2015年6月，在租住公屋启正村发现饮用水铅含量超标。引起了人们对饮用水质量的高度预期和担忧。如果供水管道中含有铅，铅就会进入饮用水。这种物质通常在黄铜水龙头和含铅焊料的管道中发现。铅会进入水中，尤其是在热水系统中。目前在香港，建筑物内部的配水系统，特别是从水表到住宅单位末端水点的配水管道，普遍采用铜水管输水。因此，这一问题引起了人们对其与健康有关的重要问题的更多关注。
考虑“预防”是消除问题的最好方法，虽然没有百分之百的安全或理想的材料在世界上，但我们可以考虑选择更合适的材料来防止事故。另一方面，也将对适当和适当的工作程序进行评价，并加强监测，以满足人类的安全水质。

One of the most important elements which are essential for the sustenance of life on earth is fresh water. It is something which forms to be lifeline for all. The importance of water is such that the body needs 50%-60% of water. In the present times, water is being used for a large number of tasks including irrigation, agriculture and a number of other things. In addition to this, water is used for a number of other tasks. It can simply be regarded as the gift which is provided by the nature to all the human beings. The human bodies require water in abundance quantities. The water which is used for drinking should be very healthy. This is important as the drinking water should be free from all kinds of impurities. In general the water which is being supplied to human beings comes from the pipelines. The water which is present in these pipelines is not completely pure. Thus, it is very important to ensure that the water which comes from the pipe is fit for drinking. One of the most important problems related to water in the public areas is the problem of water consisting of lead. This lead can easily go into water and can be very harmful for the human life. In addition to this a number of chemical effluents also pollute water. It is another kind of hazardous water pollutant (World Health Organization, 2004). Chemical water pollution may include a number of chemical effluents such as metals and solvents from the industry. These chemicals are poisonous and if taken, may be hazardous. In addition to this the pesticides is another hazardous chemical which may pollute water. Another pollutant is the biofilm. It is the collection of inorganic and organic and inorganic, living or dead material which is being collected at a surface (World Health Organization, 2003). As a result of the biofilm in drinking water pipes, there are a number of problems. These can cause a number of problems such as the increase in the bacterial levels, taste and odor changes, red and black water problems.
The Human Pursuit of more Healthier of Life In Hong Kong, the economic developed and the peoples continuously improve their level of knowledge in last 30 years. At 80’s, Hong Kong was growing quickly. The information and communication technology was also advance expansion especially the internet has become mature developed. The place was changed the nature from an industrial to a modern commercial city (Misiūnas, 2008). The people was started to pursue a more luxury lifestyle by the improvement on their economic condition. By the advantages on the economic development, the peoples would allow to enhance their knowledge to widening their sight. Under the circumstances, the people would learn and found the newly information from different channels. Meanwhile, the people would more focus on their health or concerning on improvement their lifestyle quality.
Lead Problem Found in Drinking Water at Public Estate Public rental estate is the most important housing policy to solve the living problem for Hong Kong. As know, this small city containing with high population density of people. The high rise and practical government’s subsidized rental residential building would allow accommodating around 720 household and 3,000 peoples in a single building (Tamminen et al., 2008). In the June 2015, the excessive lead containing in drinking water at the public rental estate – Kai Ching Estate was discovered. There was caused highly anticipate and worried about the drinking water quality. Lead can enter to the drinking water if the service pipe is containing with lead. The matter was commonly found in brass faucets and piping with lead solder. The lead can get into the water especially in hot water system. Nowadays in Hong Kong, the copper water pipes is very common to adopted for conveying the water for distribution system inside the building especially at the distribution pipe from the water meter to the end water points of residential flat. Therefore, the problem was drawn much more attention about their vital issues which concerning on health.
Consideration “Prevention” is the Best Way to Eliminate the Problem although there do not have the one hundred percent safety or ideally material in the world but we could allow to considerate to choose the much more suitable material to prevent the incident. On the other hand, the evaluation on the adequate and proper working procedure and enhancing the monitoring would also be achieve to satisfy the safe water quality for the humans.
