Air pollution

This is a video about pollution.

To be more specific, it is a video about “air pollution”. In this video we have tried to highlight on problems that’s have been creating for pollution & why are these causing. This video has been made for the better understanding  about what is air pollution, what are the bad effect of its, why it causes etc. 

We have discussed it widely in our previous articles. This video is only a part of that article. This is about “Air Pollution” but there are lots of different type of pollution in our environment which we have mentioned early. We would love to make more videos on environment pollution in future if you give us full support.

Water pollution

One of the most important things is that you are not drinking polluted water when you want to drink it. In this article we will discuss about water pollution. Water pollution can caused for many reasons. One of the most dangerous water pollution is arsenic pollution.

Among many water pollution causes arsenic pollution is serious problem. You have to make sure that the water you are drinking is free from arsenic in order to protect your health from serious health injury. You have to be sure that you water purifier is able to purify arsenic from water.
 
Water is an important element of the human body.

Almost 65% of a human body is water. We cannot quench our thirst without water. Now think that what will happen if you are not able to ensure safe drinking water. Many things can happen when you will fail to ensure safe drinking water. Chemical contamination in drinking water is one of them. Arsenic contamination in one of them. In fact it is the leading one.
 
Contamination in drinking water is an age old problem.

Arsenic contamination is a recent problem though the chemical element “arsenic” has been discovered in 1250. Arsenic as a pollutant on water is not much older. It mainly cause for the industrial waste dumped into water or other contaminated element dumped into water directly.

We know that soil can filter any kind of elements. When these pollutants drops down to earth, it definitely cause land pollution. But that’s not the end, soil filter those pollutants and distinguish the contaminated elements from it. Surface water is a great source of pure drinking water. But when those contaminated elements reach to that source than water pollution causes.

Arsenic poisoning

 
Arsenic poisoning is harmful to human health; there is no doubt about it. But there is a measurement. Certain amount of arsenic in not that much harmful. When this level is exceed than arsenic poisoning symptoms appears.

It’s very threatening when you find arsenic in your drinking water. What would be your thought when you will be informed that your source of drinking is contaminated by arsenic? A minimum amount of arsenic in water is acceptable. But when the amount exceeds the limit than it became life threatening.

Presence of arsenic in drinking is direct threat to your health and life also. Several life threatening disease can cause for arsenic contamination. In a resent survey it has been found that several negative effects on our body can happen due to arsenic pollution.

One of the greatest arsenic poisoning symptoms that can happen from arsenic Contamination in drinking water is cancer. When the amount of arsenic is high on the source of water and a person is drinking that from a long period of time, than he or she can suffer from cancer.

Types of cancer can vary from person to person & country to country. Amount of arsenic and consuming time of drinking water should also be listed. There may be various types of cancer for arsenic contamination, such as bladder cancer, lung cancer, skin cancer, liver cancer and kidney cancer.

Many scientists believe that arsenic pollution causes birth defects. Arsenic pollutants slowly poison our body and cause serious damage of our peripheral nerve system. It creates harmful layer between our nerves and blood vessels. There are many other types of arsenic poisoning symptoms.

The main problem of arsenic pollution is that it could not easily detected. The process of arsenic contamination is very lengthy process. In several case studies it has seen that arsenic contamination is detected after a long period of time as 6 or 10 years.

Suppose you are drinking arsenic contaminated water for two or three months. It’s not enough to detect arsenic problem. Even the effects of arsenic pollution are not visible in many cases. This is why arsenic contamination is one of the dangerous water pollution causes.

So it is important for us to be aware of arsenic contamination. For that we have to be conscious about our drinking water. We should know what we are drinking. It should be remembered that water is vital element to live & other members of my family is also drinking it. So we should stay safe & make other members of our family protected from arsenic contamination.

What is Indoor air pollution

I am pretty much sure that you have clear concept on pollution, especially on air pollution.

You know what is air pollution and for what reason it happens. We all know what air pollution is but many of us didn’t know that we can categorize air pollution into two parts.

1. Indoor air pollution

2. Outdoor air pollution.

To common people air pollution only happens in the open road/area. They have no idea about indoor air pollution. They cannot even imagine indoor air pollution as pollution. In this topic we will try  to discuss about:

  • What is indoor air pollution?
  • Why it causes?
  • Who/what is responsible for it?

 

Now come to the first point, what is indoor air pollution?

The answer is very simple. When air polluted by those destructive and harmful elements/pollutants that comes from those equipment which we generally use in home for our daily comfort.

I am not telling that all the home equipment’s are bad. But there is some high configured machine that is causing air pollution. We are using those for our personal benefits. It is also true that indoor air pollution doesn’t cause for only the equipment, other things are responsible too.

The causes of air pollution

 
It’s time to talk about second topic, why it causes?

If I want to answer this in simple the answer would be easy. It’s our ignorance which is mainly responsible for it. Besides that the other elements are also responsible. We have to remember that those elements are used by us. So directly or indirectly the responsibility comes to us.

Another reason may be culture and trends of society. The culture of any developed country or mega city. The people in Australia, Canada or New York get used to with this kind of pollution because of their social trends.
 
The last topic of this article is who/what is responsible for it? I kind of answered this question before but now I would like to focus more detail. Let us think it like a story.

Mr. jone lives in New York. He come back from work & starts the air conditioner to heat up the room. Then he fires the stove and makes a nice cup of coffee. Than he sit in front of the TV set & enjoys his coffee with a cigarette. No traffic noise can disturb him because the window was closed.

This is a common matter in those cities. What we can get from this? There are some regular activities of jone which is quite normal but if we can look deeply there are some problems. Some activities of jone is causing indoor air pollution. Now you will ask me which one is causing pollution.
 
Let’s take a close look.

Air conditioner of jone is creating CFC gas.When he was making coffee then the stove was burning oxygen and producing other harmful gas.Smoking of jone is producing lots of harmful chemical gas.By closing window jone stops all kind of flow of air.

We have an analysis on the topic and tried to understand about air pollution (indoor). Air pollution is a great problem. Indoor air pollution is only a part of it. Indoor air pollution can easily be stopped or reduced. How we can solve the indoor air pollution will be discussed in next post.
 
If you are a smoker than this article might hurt your fillings because I will try to discuss about the bad effect of smoking. Let me tell you that my approach will be different than your thought. Many of you will think that I will tell you “smoking is bad”  “don’t smoke”  “it’s bad for your health”.

I won’t tell you that because I know that you already know that. Infect all the smoker do. Today my point will be “smoking is harmful for health, but it is also harmful for environment”. Yes smoking does create harmful effect on environment.

It’s a common thought of almost every smoker that “I know that by smoking I am doing harm to my health. So what? It’s my choice”. If you really think like this than please let me say that you are not right at all. Doing like this also affect others heath also.

What do you think; environment means only air, water, land and sky? No, human are also important part of environment. By affecting them you are also affecting the environment. It is just one side of a coin.

The story of other part of the coin is that by smoking a smoker is contributing harm directly to the environment.  There are some points that the smoker should know before they smoke. I will discuss those points in other article but a smoker should remind himself one thing very clearly that they are not only causing harm to their self but also they are contributing harm to the environment.
 

Water pollution

 
Raindrops are falling on my headand just like the guy who’s feet are too big for his bed,nothing seems to fit those, raindrops are falling on my head, they keep falling…

Many of us have heard of this song. This song is so classical that whenever I listen to this song, my mind fills up with joy. It’s obvious that Rain plays an important role in environment. It’s an important part of environmental cycle. Rain also tunes our emotion. It’s a symbol of romanticism. When it starts raining we feel great pleasure like a cord of piano. Rain has helped human to create great literature.

But what will happen if the Rain turns in to horror. What if the symbol of romanticism threats you of your life? Can you imagine that rain drops could be a cause of death?

If the dangerous situation described above are true then what will happen? Unfortunately rain can cause dangerous damage when the rain drops turn into acid instead of water. Acid rain was first discovered in 1852 by an English chemist & the name of the chemist is Robert Angus.

What is acid rain?

Now i will define acid rain. Acid rain means the precipitation of rain drops that is toxic by harmful elements such as hydrogen ions (which contain low level of pH), harmful gas carbon dioxide, sulfur dioxides & nitrogen oxides.

These elements pollutes total atmosphere. Particularly this cause water pollution.  Mainly these occur from nitrogen & sulfur dioxide released from cars or other types of vehicle. Industrial chemical waste that is dumped into water is also an cause of acid rain.

Point to be noted that acid rain could be precipitated anything such as water, snow, hail, fog & pieces of ice. Among these entire elements one thing will be common – they all will be acidic.

We can learn from this acid rain essay is that there are two way of acid rain:

  • Dry or non-wet deposition

    •                   

  • Wet or liquid deposition

Now these term refers should be explained. These are also the causes of acid rain.
 

Dry or non-wet deposition

There are many area where the climate is dry in nature & here the dry deposition occurs. Chemicals from industrial factories transferred into dry dust or may be smoke & than it mixed up into ground through non-wet deposition. This dry deposition is polluting not only ground but also other materials.

These dry deposited gases and particles can be washed from these surfaces by rainstorms, leading to increased runoff. This runoff water makes the resulting mixture more acidic. About half of the acidity in the atmosphere falls back to earth through dry deposition.
 

Wet or liquid deposition

It is easily understandable that these kinds of depositions are not solid. Some example of Wet or liquid deposition are snow fall, heavy fog & rain.

There is no doubt that all the elements will be harmful. When local area is polluted by acidic chemical then it’s quite possible that the acid rain will fall in the form of those elements (acidic rain fall, heavy fog & snow).  

In wet deposition mainly the weather is wet in nature. Let us think deeply about this matter, acid rain or acid pollution is creating from the very land that we are living on and after traveling atmosphere it is returning back to our ground.

These polluted elements are being mixed into the soil. It is not only polluting the structure of soil but also the plants & animals are being harmed by it. Of course the effect is different from land to land. The measurement of pollution to fish in the water, animal on the forest would also be different.

What Are Landfills?

When A Landfill Hits Capacity, What Happens Next?

while a landfill reaches capacity, it is restricted and restored so that it can be converted into green places like parks & community grounds. After capping, these will last for up to 30 years.

Landfills might take several years to achieve full capacity, depending on the type and volume of garbage. The final section of cover material, clay, and vegetation is then applied to the landfill. This cap layer acts as a barrier, allowing scents to pass through while keeping precipitation out. When the site is recovered for recreation and light cultivation, it will be planted to fit its future usage.

What Are The Negative Effects Of Landfills On The Environment?

Landfills are unsightly. And the problem isn’t simply the eyesore of growing rubbish piles; landfills are also bad for wildlife, environment, the environment, and global warming. They’re a big source of pollution, & they come with a slew of other drawbacks. Waste dumped in landfills takes a long time to disintegrate, posing a threat to future generations.

Toxins, leachate, and greenhouse gases are the three main issues of landfills Organic trash produces bacteria that decompose organic waste. Decomposition of garbage produces weak acidic compounds, which interact with waste liquids to form leachate & landfill gas.

There are also some secondary impacts, such as disagreeable odors, unappealing views, and rat and bird infestations, which produce their own garbage.

Toxins

Toxic chemicals can be found in many waste materials. One example is electronic garbage. Mercury, arsenic,  PVC, solvents, cadmium, acids, and lead are among the toxic compounds found in waste including such televisions, computers, and other electronic gadgets. These pollutants permeate into our soil &  groundwater over time, posing long-term environmental risks.

Leachate

Leachate is a liquid that forms when garbage decomposes in a landfill & water filters through it. This highly poisonous liquid has the potential to damage land, groundwater, and waterways.

The environment is harmed by the huge quantities of pollutants found in landfills. When plastics, such as PVC, and other materials degrade, they release harmful compounds.

In the developed world, e-waste is the quickest increasing trash segment. Despite the fact that it is the most harmful everyday liquid waste of all, the majority of it is disposed of in landfills. Heavy metals, solvents, & acids abound in electronic trash.

Each landfill cell takes a year or more to fill, during which time the materials are naturally exposed to rainfall. Rainwater seeping the landfill dissolves & flushes 5-7 % of the poisons, resulting in leachate, a foul-smelling liquor containing ammonia and various harmful ions.

A single landfill site could easily produce several Olympic-sized pools of leachate each year, depending on rainfall. To avoid contamination of land, groundwater, and waterways, leachate is carefully collected & recirculated into landfill cells. When leachate is returned to the landfill, some of it is reabsorbed, but the rest filters via again, taking up more pollutants each time.

Landfills Are Possibly The Most Significant Source Of Greenhouse Gas Emissions.

Organic waste, including such food scraps & green trash, is typically compacted and covered when disposed of in landfills. This depletes the oxygen supply, resulting in  anaerobic process. Methane, a green house gases 25 times more powerful than carbon dioxide, is eventually released. 35-55 percent methane and 30-44 percent carbon dioxide make up landfill gas.

Methane is also a combustible gas that, if allowed to build up in concentration, can be harmful. The consequences of global warming &  climate change were huge. Many of these issues can be avoided by composting your food scraps & green waste in  compost bin.

Methane’s greenhouse effect is significantly harsher than carbon dioxide’s within the first 20 years of emission—between 84 and 100 times more strong. And, in terms of reducing greenhouse gas emissions, what matters most is what occurs in the next 10 to 20 years.

So, how much methane does a normal landfill produce? Quite a bit. Enough to power a power plant, in fact.

A landfill which serves a half-million people, for example, produces almost 1.7 million cubic meter of methane each month. Typically, 85 percent of this gas is caught and used to power a generator that serves around 10,000 houses.

While landfill gas power is frequently referred to as renewable energy generation by plant operators and governments, it is neither sustainable nor environmentally benign. Methane, like oil and coal, produces carbon dioxide when burned.
