Instr. Poffenroth Biology 21, Section 1 28 October 2015 Air Pollution’s Effect on the Respiratory System and the Cardiovascular System Air pollution is everywhere in today’s society from vehicles power plants, industries, and even forest fires. These pollutants are either manmade or from natural sources. No matter where they come from one thing they have in common is that these different kinds of pollutants are harmful to people’s health. Air pollutants affect the body’s organ systems causing damage
Pollution The air we breathe, the water we drink, the ground where we grow our food, is polluted with harmful things. Pollution is the introduction of harmful or poisonous effects of a substance into the environment. It disrupts the balance of people’s lifestyle when they are contaminate. Pollution balance in the environment and ecosystem. The environment is in the process of becoming unsafe or unsuitable to use. Pollution can come in many different form, such as air, water, soil can have pollutant
Air Pollution Air pollution is a combination of gases and solid particles in the air. Air pollution can also be described as harmful substances that pollute the earth’s atmosphere. Air pollution refers to the contamination of the air, indoors, or outdoors. Air pollution occurs when hazardous substances such as dust, lead, or smoke enter the atmosphere and make it difficult for not only humans, but plants and animals to survive because of the quality of the air. Some examples of air pollutants
Pollution is one of many major hazards that cause problems to not only people but to the environment as a whole. Pollution is the contamination of a natural environment that can cause discomfort and harm to an ecosystem and those inside of it. Pollution occurs mainly in three forms: air, water and noise, all three of which have two sources of occurrence, the point and the non-point sources. All forms of pollution affect our ecosystem in many different ways. Air pollution is one of three major forms
Introduction Pollution is serious problem that influence our normal day lives, especially in the industrial city such as London in the middle of 18th century. Nowadays, pollution problem is getting worse and worse all around the world and people’s lives are effected from it. For example, the Air pollution problem in Beijing or the water pollution problem in East China Sea. Pollution is defined as” the action of polluting especially by environmental contamination with man-made waste.” in merriam-webster
important because it helps the body fight any foreign bacteria, viruses, and diseases by attacking it, which is why we must take care of it as much as possible by strengthening it. But this so called defense system can also cause problems such as attacking donated organs or blood from another individual, unless the organs or blood are carefully matched. It may also overreact to harmless invaders such as pollen grains, which can cause hayfever, and even in certain cases, the immune system may turn against
The world is always full of problems. Some are more important than others while others are not important at all. One of the biggest problems the world has to face is air pollution. Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen, and mold spores are often suspended as particles. Since some air pollutants are poisonous, inhaling them can cause a risk to health issues such as heart and lung disease. Also, according to the World
In recent years, air pollution has become a growing problem in China (Zhang, Chao). According to the newly released scientific paper by Dan Levin, outdoor air pollution contrib7utes to the deaths of 1.6 million people in China every year, and about 4,400 people a day (Levin, Dan). Essentially, air is a major part of our overall health. However, people (including ourselves), especially living in developed countries, suffer from the exposure of air pollution. This potentially puts our health at risk
caused by pollution and Air pollution is the fourth highest risk factor of death globally.” According Professor Michael B. from the university of british columbia analysed that two countries accounts “55 percent of their deaths were caused by air pollution”. China had 1.6 and India had 1.4 million deaths due to air pollution. Pollution is when gases, smokes and chemical are released in the air which is a major threat to the environment, humans, plant and animals. Some of the world's pollution is are
deaths- as a result of air pollution exposure.” (http://www.who.int/mediacentre/news/releases/2014/air-pollution/en/) The definition of air pollution is the air contains gases, dust, fumes or odor in harmful amounts. That is, amounts which could be harmful to the health or comfort of humans and animals or which could cause damage to plants and materials. Primary air pollutant includes carbon monoxide from car exhausts and sulfur dioxide from the combustion of coal. Further pollution can arise if pollutants
