Right now, our rivers, streams, reservoirs, lakes and seas are slowly polluting chemicals, wastes, plastics and many other pollutants. This is the reason that water resources are seriously polluted, negatively affecting human health as well as animals and plants caused by water pollution .
An English poet named Auden once said: "Thousands of people have lived without love, but cannot live without water". However, as we all know, water is so important to our bodies, but a lot of people keep rubbish out every school day. According to experts' estimates, up to 90% of wastewater in Vietnam is discharged directly into the environment without any treatment, this problem has polluted rivers, lakes as well as oceans.
Water pollution is quite common in Vietnam and has a very negative impact on the health of the people. The water source is killing more people indirectly each year and is on the rise over time. In Vietnam, the natural source of water that is potable and harmless to the body is almost zero. If we don't take action, the clean water we can use in the future will be less. quite a lot compared to the present.
As you are reading this article and holding a glass of cool water in hand, I am sure a lot of people will think water pollution is a problem elsewhere, not here. Meanwhile, many water sources in Vietnam have been contaminated with harmful substances such as arsenic, copper, lead, ... found in the tap water used every day.
We do not hope that this can be countered, but there will be a way to reduce water pollution by giving an overview of the polluted water sources, the causes and how we can protect ourselves. protect from pollution.
Water pollution is when toxic substances, chemicals or microorganisms contaminate a stream, river, lake, sea, aquifer or other water source, this water will harm the health of People and the environment.
Water pollution can directly affect our health as well as the animals and plants that come into contact with water, especially animals living in polluted water.
Currently, there are many causes of water pollution and one of the main reasons is caused by human waste. Here is a list of 9 main causes of water pollution:
Industries are producing large amounts of waste containing toxic substances that can seriously pollute the environment and pollute the air and water resources and directly affect us as humans.
hese industrial wastes contain toxic chemicals such as lead, mercury, sulfur, asbestos, nitrates and many more. Many industries do not have wastewater treatment systems that discharge directly into the environment (sewer pipes, rivers, etc.) and then into the sea. It is this dirty waste that causes the water source to change color and temperature and cause danger to the organisms in the water source.
Wastewater and sewage water is the source that directly affects the water sources of rivers and the sea. In these wastewater sources there are many bacteria and chemicals that can harm human health. This is a common cause of many dangerous diseases among many people.
It is well known that organisms present in water sources can indirectly or directly cause some dangerous diseases for humans and animals, when small animals come into contact, can cause pathogens, and when pathogens are present. This relapse can cause a lot of different diseases, directly affecting us. The most common example anyone knows is malaria.
Every day, households provide a large amount of waste such as rubber, glass, plastic, paper, aluminum, ... and a lot of that is discharged directly into the environment (of course we just say The majority, but not all) directly affects the land as well as rivers, streams, ...
These types of waste can take from half a month to 200 years to decompose on their own. When these wastes fall into the water, they not only pollute the water, but also cause serious harm to the animals living in the water.
When we travel on the road by means such as motorcycles, cars, ... the burning process of gasoline creates a considerable amount of smoke and dust in the air, when it rains, toxic gases are present in the air. will flow according to the water source and directly affect the water source.
In addition, the burning of these fuels produces carbon dioxide, which is discharged directly into the environment, leading to global warming.
Chemical fertilizers and pesticides are used by farmers to protect plants from insects and bacteria, they are quite useful for plant growth.
However, these chemicals, when exposed to water, pose many dangers to both animals and plants. When it rains or when watering crops, these chemicals will flow through the water source to streams, rivers, ... negatively affecting the animals in the water source.
A small leak in the drainage pipes could also contaminate the groundwater and make it impossible for the people living nearby to use it for drinking.
Also, when these leaking pipes become more serious without being repaired in time, this leaking water will flow to the surface and this will be a great place for mosquitoes and pathogenic insects to breed.
Along with the population growth due to the process of industrialization and modernization, the demand for housing, food, cloth ... has also increased significantly, which has pushed the problem of environmental pollution. School takes place more strongly.
In addition, the increase in production to meet social needs with fertilizers to create more food, soil erosion due to deforestation, construction activities is much more accelerated, the process of harvesting Collection and treatment of waste, waste water is not thoroughly, ... has made the process of pollution worse every day.
Landfills are places where a large amount of waste is collected from a large area for disposal, in these areas, the air smells terrible.
When it rains, these landfills can leak and seriously pollute the groundwater.
They can also directly affect the surrounding environment, especially the households living around these landfills.
The production and husbandry of animals such as chickens, pigs, cows, ... has discharged a large amount of waste from animal manure into rivers and streams.
When it rains, this waste is sent to rivers, streams, combined with other toxic substances in the water source, causing a number of diseases such as cholera, diarrhea, dysentery, ... negative effects. to human health as well as to animal health.
Currently, we have 2 main water sources, each water source will have a different level of pollution and different levels of impact on human health. The following are the types of water pollution:
Groundwater is the type of water that when rainwater falls and penetrates deep into the ground, this water source will fill cracks, crevices as well as porous space of the aquifer (We can simply understand it as a water storage. (underground), it becomes groundwater, one of the few natural resources found but very important in our lives.
In fact, water pollution caused the deaths of more than 1.8 million people in 2015 (This is a statistic from a study published in The Lancet ). And now, polluted water infects billions of people every year around the world. Subjects most susceptible to diseases caused by water pollution are low-income ones because they are frequently exposed to this polluted water source.
Causes of illness from contaminated drinking water are pathogenic bacteria and viruses present in the water. Mainly diseases such as cholera, diarrhea, malaria.
In Vietnam, maybe not everyone lacks clean water to use, but many countries around the world are facing the problem of lack of water for daily use, partly due to weather, part The rest is due to water contaminated with heavy metals such as arsenic, mercury or pesticides, fertilizers, ... these toxins are gradually entering the water supply for us to use every day. When we eat or drink, these toxins cause a variety of health problems, from cancer to the breakdown of hormones, even altered brain functions. The subjects most at risk of infection are children and women.
Even while swimming in this contaminated water, we can experience health problems such as skin rashes, nosebleeds, respiratory tract infections, and even hepatitis.
he environment is a complex network of ecosystems of animals, plants, bacteria and fungi that interact directly or indirectly with. If there is any harm to this ecosystem, it will affect the reaction chain of the ecosystem, causing the living environment to be altered.
When water pollution occurs, the proliferation of new nutrients in the water source inadvertently stimulates the growth of plants and algae, resulting in a significant reduction in oxygen. This lack of oxygen kills plants and animals present in the water and creates dead zones where the water sources are inhabited by organisms.
Chemicals and heavy metals from urban and industrial wastewater also pollute water sources. These pollutants are very toxic to the organism in the water source, it reduces the fertility as well as the longevity of the organism.
Solid waste such as plastic bags, plastic bags, bottles of fresh water, ... caught in the sewers and discharged into rivers and streams will directly affect the organisms in the water source.
Water pollution is a problem of society, however, each person can contribute a certain amount of strength in the work of water environment protection in the following ways:
Here are some simple solutions that you can contribute to reduce, prevent water pollution or at least you can reduce it.
- Reduce plastic consumption and reuse or recycle plastic when available you can
- Properly handle chemical cleaners, oils and non-degradable abrasives
- If you ride 3 or more wheels, beware of oil, lubricant or coolant leaks
Minimize the use of pesticides or herbicides and reasonably reduce soil erosion around your home.
- If you have a pet, make sure you remove its droppings carefully
One of the most effective ways for you to reduce polluted water is to call out to friends, siblings, family members, ... by sharing this article with them and calling for they protect the polluted water environment that is increasing every day.
When you see any problem about environmental pollution, you can share it on social networks such as Facebook, youtube, twitter, ... to access the voice of the online community.
Summary : Water pollution is getting worse and worse, so just a little action can reduce its pollution level, protecting the water you are using. day.
