Since the beginning of industrialization, pollution has become an environmental problem more and more. In Western countries, the amount of pollution has increased continuously. What is interesting to note, is that the number of people suffering from allergies has also been on the rise. Types of pollution vary pollutant chemical such that of the particulate matter, nitrogen dioxide and ozone at busy locations, natural outdoor pollutants such as pollen. Is there a link between pollution and allergy? This article will examine the link between allergies and a range of different pollutants.
Account of diesel particulate up to 90% of the airborne particulate matter of importance in the atmosphere of the largest cities in the world. These particles are known to stimulate the growth of cells that lead to allergic risk. Scientists at the Japan exposed Diesel exhaust to Guinea pigs to determine its effects on allergies. They found a clear result that diesel exhaust increases the responses of airway induced by the allergen, typical for allergic diseases such as hay fever. This is supported by numerous other studies. Recent research from the United Kingdom and the Netherlands found that children living near roads and high traffic areas suffer from an increase in respiratory problems and a decrease in the ability of the lungs to function. The level of particles in the air increases, so too did products symptoms.
Tobacco smoke room is a very common indoor pollutant. Clear links between smoking and respiratory symptoms such as asthma are well established. Studies of smoke in rats found an increase in the production of the allergic cell-related diseases.
The pollen is an allergen largely responsible for respiratory diseases such as hay fever. It is interesting to note that landscape in most of the cities of the world tend to use male plants in their designs rather than the female. The reason is that seeds of trees falling females, pods, messy fruits and other detritus while male trees are "litter-free" yet they produce huge quantities of pollen. This has some importance, as many people allergic to pollen and by increasing the amount of this air pollutant, this could have an effect on the increase in the prevalence of allergies. A study to the Japan revealed a higher number of people who are allergic to living Cedars in the vicinity of the motorway than those living further away. Two groups of people had the same degree of exposure to pollen. A recent study in four European cities found allergens such as pollen would stick to pollution particles in the air. This would suggest that as pollution in the air exhaust systems increases, they become carriers of allergens such as pollen. Findings like this show that various pollutants act together and increase their impact on society.
