Pathogens: Overcoming Physical And Chemical Barriers

Air pollution is when there is a presence in the air of a substance that has harmful or poisonous effects. There is air pollution almost everywhere in the world. This is due to industrialization. The world today depends on things that emit hazardous fumes and other hazardous pollutants in the air. Air pollution that is hazardous or toxic can have health risks. Some of these risks range from skin rash, cough and headache to cancer, nervous system damage and birth defects. There are no positive effects of air pollution. Air pollution is also in the form of acid rain. Acid rain pours wherever it’s ready. Acid rain destroys plants, harms animals, fish and other wildlife. Humans aren’t the only ones affected by air pollution everything is affected.

Air pollution is a big problem in our world today because it affects our lives on earth as well as animals and plants. Breathing polluted air can make you very sick it can cause your eyes and nose to burn. It can irritate your throat and even make your breathing difficult. Air pollution is a big environmental problem because it is affecting our crops, trees, wildlife, and lakes/oceans. Pollution is harming fish and other aquatic life in those bodies of water.

The problems that develop from this is bad lung function. This condition is affecting many people and diagnosed as asthma. It prevents people from strenuous activity because they can catch their breath. All the chemicals that are in the air affect our genome as well. Which will cause deficiency in our immune system. This will put us at risk for developing other disease not just asthma. In the Gale database “Asthma, heredity and air pollution” research shows that “air pollution exposure suppressed the immune system's regulatory T cells (Treg), and that the decreased level of Treg function was linked to greater severity of asthma symptoms and lower lung capacity” (“Asthma”). Therefore it affects everybody not just the people that have asthma. It has come to the point that they have a flag code to indicate how bad our air quality is. They indicate what days are safe for rigorous outside activity, moderate activity, or just be enclosed in your

Everyone in the New York metropolitan area breathes air that fails to meet the health standards, and citizens suffer serious health impact from breathing that dirty air. The relationship between air pollution and health affects everyone. Air pollution is constantly affecting people and putting them at sick, even though the degree of pollution is not at its highest. The public health significance of smoke, dust, gas, pollen, and microorganisms in the air are with a range of adverse health effects. These diseases spread and cause new disease to originate. Exposure to common urban air link to a wide range of adverse health outcomes, including respiratory and cardiovascular diseases, asthma exacerbation, reduced lung function and premature death.

In active immunity, the patient produces antibodies, which are life long. An example of active immunity would be vaccinations, after receiving a vaccination the patient produces antibodies in response to a foreign antigen, but the pathogen is dead or weakened. Another example would be the exposure to a disease, such as the chicken pox or a cold virus, the patient produces antibodies in response to the unfamiliar or foreign antigen. In passive immunity, the patient is given antibodies, but these are only temporary. An example of this would be breastfeeding. While an infant is breastfeeding, it is given antibodies from the mother.Another example of passive immunity would be Gamma globulin injection, with this the patient is given antibodies

Diseases caused by pollution (Asthma)- Asthma , which is a lung condition, is due to air pollution which can cause us some issues breathing. A few reports within the UK say asthma ‘kills 40000 a year’. Pollution make people more open to dangerous chemicals such as, carbon monoxide which can cause poisoning. Symptoms of asthma are:

The ebook, Focus on Pharmacology, explains on page 114 that the active immunity is acquired immunity. And Google dictionary states that this acquired immunity is from either the development of antibodies as a response to antigen exposure (1) from vaccination or (2) an attack of an infectious disease. Whereas passive immunity is the result of the introduction of antibodies from another person or animal. The example given in the ebook is of a mother exposing the fetus or when the mother breastfeeds her infant. One major difference between them is that passive immunity is much quicker but the duration is a lot shorter than the active immunity.

At the first, what is air pollution? The air pollution is contamination of air by the discharge of harmful substances. We’ve got many pollutants, which cause air pollution. Like carbon monoxide, carbon dioxide, chlorofluorocarbons, lead and many more. All of these pollutants can cause lot of illnesses, like cancer, birth defects, brain and nerve damage, long-term injury to the

In addition, Air pollution influences the liveability of places negatively as it's a push factor. Air pollution has a diverse range of impacts that influence livability through diseases and poor quality that could lead to many infections, diseases, or maybe even death from the toxic gas, carbon dioxide generated from motor vehicles or chemicals that are produced.

Air pollution can affect those with asthma, especially children. Researchers did a test to see whether air pollution caused by vehicles was a factor that affected the respiratory system of children, ages ten to eighteen (Jerrett et al., 2008). They gathered a selection of children and tested the air in their surrounding area as well as recorded data regarding any effects the air around them had placed on

ronment? Air pollution affects our environment because it causes health problems, negatively affects the economy, and causes drastic weather changes. Air pollution is one of the world 's biggest killers. It is made up of gases that are released into the air in large quantities. These gases are capable of harming humans, animals, plants, and our climate.

The damage that results from air pollution can never be overstated. There are health problems like the risks of cardiac diseases, acute and chronic respiratory diseases like asthma, lung cancer and so forth (Aryes, Maynard, & Richards, 2006). Corrosion dud to formation of acid rain, global warming and poor visibility reduces are but some of other issues mentioned randomly. More than two million deaths are linked to air quality. The worrying observation from analyst has been that there have been frequent alerts on the state of the atmospheric

Air pollution is known to create several respiratory and heart conditions along with Cancer, among other threats to the body. Millions are known to have died due to direct or indirect effects of Air pollution. People in areas exposed to air pollutants are said to commonly suffer from pneumonia and asthma.

The effects that are caused on the human body due to the ingestion of these gases and pollution is devastating as well. Air pollution causes a wide variety of respiratory issues. The symptoms that can come from the inhalation of said air pollution
