What harm does drinking the landscape of eucalyptus forest do to human body? Thank you, everyone.

In fact, with the development of industrialization, mountains and rivers will be polluted, which is unsafe to drink and has health risks. The reasons are as follows: ◆ 1 Zhongshan City is one of the cities with the most serious acid rain in Guangdong Province. Acid rain is mainly composed of acid gases such as sulfur dioxide and nitrogen oxides produced by the combustion of fossil fuels, which are absorbed and dissolved by rainwater after complicated atmospheric chemical reactions. Mountains and rivers originate from rain and are formed by gathering atmospheric rainfall through mountainous terrain. Although the natural filtration of mountains and rivers by sandy soil will remove some harmful components to human health, there is no difference between mountains and rivers polluted by acid rain and acid rain. Acid rain is harmful to human health in two aspects. One is direct harm: acid rain will obviously stimulate cornea and respiratory mucosa, and will cause respiratory diseases, leading to pinkeye and bronchitis; Can make children's immunity decline, easy to be infected with chronic pharyngitis and bronchial asthma, leading to an increase in the prevalence of eyes and respiratory tract in the elderly. Second, indirect harm: acid rain reacts with soil, which can precipitate heavy metals such as mercury, lead and cadmium contained in soil and pollute mountains and rivers. These heavy metals cannot be decomposed in water. Drinking mountains and rivers containing heavy metals for a long time will cause headache, dizziness, insomnia, forgetfulness, insanity, joint pain, stones, cancer and so on. After accumulating a certain amount in the body. Especially the cells, organs, skin, bones and spirit of digestive system and urinary system. ◆ Second, the mountains with rich vegetation will have mountains and rivers all year round. Similarly, mountainous areas with rich vegetation are places where snakes, insects, rats, ants, frogs, birds or other wild animals like to inhabit and live. Many of these species will carry pathogenic bacteria or parasites on their bodies or bodies. Rainwater or mountains and rivers will flow through their places of activity, and will be polluted by their places of activity, and feces or carrion will carry pathogenic bacteria or parasites. Drinking landscapes containing pathogenic bacteria or parasites will cause diseases. ◆ Third, the litter accumulated on the mountain for many years will turn into humus. Once humus is soaked in water for fermentation, it will undergo anaerobic reaction, producing toxic and harmful substances such as sulfide and nitrite, which are also carcinogens. ◆ Suggestion: Don't drink raw mountain water (some water dispensers can only be heated to 90 degrees, so don't install mountain water on the water dispenser for direct drinking); Don't wash fruit with mountains and rivers. For the health of the whole family, the conditional suggestion is to buy bottled water to drink. If you drink 3 barrels of water a week, and each barrel of water is calculated as 10 yuan, then the cost of buying water for one month is less than 150 yuan. Less than 150 yuan can make a family drink water safely, so why not? If you drink mountain and river diseases, according to the current level of medical charges, it is more than this money to see a doctor.
