水是自然界一切生命的重要物质基础,是维持人类身体、心理、社会健康不可缺少的核心元素。水作为人体的主要成分与生命的命脉,对人类健康处于主导地位。研究证实,成年人肌体内的水约占体重的1/3以上;每人每天生理需水量约2-3升。研究又表明,人体细胞内一切生命活动的生化反应,都是物质溶于水之后实现的。由此可见,水不仅是人体的主要成分,而且还是细胞赖以生存的生活环境。人体的全部生理活动,如体温调节、营养输送,废物排泄等都要靠水来完成。显然,肌体内始终要保持着水分的动态平衡;倘若肌体一旦缺水或脱水,必定会损害心身健康,严重时危及生命。随着科学技术的高速发展和人们生活水平的不断提高,饮水的污染问题再次引起人们的高度重视。目前,我 Water is an important material basis for all life in nature and is an indispensable core element in maintaining human health, psychology and social health. As the main component of human body and the lifeblood of water, water plays a leading role in human health. Studies confirm that adult body water accounts for about 1/3 of the body weight; physiological water requirement per person per day is about 2-3 liters. Studies have shown that all biological activities of human cells in the biochemical reactions are substances dissolved in water to achieve. Thus, water is not only the main component of the human body, but also the living environment in which the cells depend. All physical activities of the human body, such as thermoregulation, nutrition delivery, waste excretion, etc. must rely on water to complete. Obviously, the body must always maintain the dynamic balance of water; if the body once dehydrated or dehydrated, it will certainly damage the mental and physical health, serious life-threatening. With the rapid development of science and technology and continuous improvement of people’s living standard, the pollution of drinking water once again aroused people’s attention. Currently, I
