What are the 10 causes of air pollution

 

The 10 causes of air pollution are as follows:

Air pollution is caused by both natural and man-made causes. Man-made causes are more responsible. Natural factors that are responsible for air pollution include volcanic eruptions, wind erosion, forest fires, pollen scattering, natural radioactivity and evaporation of organic compounds. The following are the 10 main causes of air pollution :

  1. Stationary source: These include power plants, various manufacturing plants, various types of reactors, fuel heating devices, waste incinerators, etc. These produce large amounts of smoke, which is a major cause of air pollution in developing and poor countries. Burning wood, crop wastes and dung also causes a lot of air pollution.
  2. Mobile source: This includes motor vehicles, ships, aircraft, etc. These cause air pollution as well as noise pollution. These vehicles emit carbon monoxide (CO). Carbon monoxide is a colorless, odorless and toxic gas. CO is also produced by incomplete combustion of natural gas, coal or wood.
  3. Gases emitted from paints, hair sprays, aerosol sprays, varnishes and other such solvents pollute the air.
  4. Wherever there is waste, it is one of the major causes of air pollution. Developing or poor countries do not have adequate waste disposal systems, leading to the accumulation of waste in the vicinity of settlements. These produce methane gas. Methane is a toxic and highly flammable gas that can form explosive mixtures with air. Incomplete combustion of methane again produces carbon monoxide which is another toxic gas.
  5. Military source: Toxic gases from military warfare, civil war, nuclear weapons, rockets, etc. are released into the air and cause air pollution.
  6. Fires are another major cause of air pollution.
  7. Radon gas from radioactive decay in the Earth's crust is another cause of air pollution. This radioactive gas is produced from the decay of radium metal. Radon is a colorless, odorless, naturally occurring radioactive gas. It is very dangerous for health. Radon gas can accumulate in buildings, especially in confined areas such as basements. Radon gas is considered to be the second leading cause of lung cancer.
  8. On hot days, plants emit significant amounts of environmentally significant VOCs in some areas. These VOCs react with primary anthropogenic pollutants such as NOx, SO2, etc. to form secondary pollutants which cause air pollution. This is one of the natural causes of air pollution.
  9. Volcanic activity which produces sulfur, chlorine and ash particulate.
  10. Dust from a large area or land without vegetation is another major cause of air pollution.


Air pollution can only be prevented if individuals and businesses stop using toxic substances. For this, everyone has to come forward. We need to make rules and apply them strictly to private and industrial organizations.

Human cheek cell under microscope

Image
Introduction The linear tissue inside the mouth is known as the basal mucosa and is made up of squamous epithelial cells. These structures, commonly referred to as cheek cells, divide about every 24 hours and continuously leave the body. The following images are of the  cheek cell under microscope. The main parts of a cheek cell : cell membrane. Nuclear membrane cytoplasm. nucleus. organelle. These are the parts that will be visible to you if you put cheek cell under a microscope. You may often see  bacteria  also but that needs a better microscope. You will not see bacteria with a low cost microscope. Requirements for cheek cell slide preparation: The things that will be needed to prepare a slide for cheek cell are: Slide Cover slip Tooth pick Dropper Methylene blue dye Microscope Tissue paper (optional) How to prepare a wet mount cheek cell ? Take a clean microscopic slide. Take a dropper and put a drop of water on the central part of the slide. ( physiological saline can also be use

Vitamin A deficiency diseases and treatment

  Diseases and symptoms of vitamin A deficiency Vitamin A deficiency diseases are mentioned below: Liver cirrhosis Celiac disease Bile duct disorder Ratkana Xerophthalmia Beetroot stains Dry skin Itching Burning of the skin Disrupting physical growth Decreased fertility and infertility Deficiency and treatment About 350,000 preschool-age children go blind each year due to vitamin A deficiency, and most of them do not survive.  The most common clinical symptoms of vitamin A deficiency are night blindness and  xerophthalmia  .  Vitamin A deficiency in young children causes beetroot spots on the conjunctiva of the eye and various eye symptoms.  Inadequate intake of vitamin A can lead to protein-calorie malnutrition, lipid malabsorption and fever.  Among adults, breastfeeding mothers are most at risk.  Treatment: The recommended treatment for xerophthalmia in children 1 to 6 years of age is 210umol retinyl palmitate.  And this dose should be repeated one day later and then 2-4 weeks later.

5 best digital microscope for kids

Image
A Digital Microscope may be a variant of optical microscope that uses optics and a photographic camera to output a picture to a monitor, typically through software package running on a PC. A digital microscope usually has its own constitutional semiconductor diode source of illumination that is completely different from an optical magnifier therein there’s no ways to observe the sample directly through the lens system. The most distinction between a stereo magnifier and a digital magnifier is their magnification. With the assistance of a stereo microscope, magnification is decided by multiplying the lens system magnification by objective magnification. Since the digital microscope doesn’t have associate degree lens system, magnification can not be obtained by this methodology. Instead the magnification for a digital microscope was mostly determined by what number times larger samples were reproduced on a 15-inch monitor. though the scale of the monitor has modified, the physical size
