Both types of pollution are harmful &amp; in this article, we will cover how pollutants end up inside the car, the harm it\u00a0causes, and what you can do to reduce it.\r\n\r\nVehicle exhaust fumes consist of carbon dioxide, carbon monoxide (which is quite lethal) and small quantities of nitrogen oxide and sulfur dioxide. The combination of these fumes produces a deadly cocktail that brings about respiratory problems when inhaled.\r\n\r\nAdditionally, it damages the ozone layer and the environment. The dangers may not be felt instantly but they become noticeable over time, causing permanent damage to our bodies and the world we live in.\r\n<h2>How Do Pollutants End Up Inside Cars?<\/h2>\r\n<figure id=\"attachment_6728\" aria-describedby=\"caption-attachment-6728\" style=\"width: 1305px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6728\" src=\"https:\/\/carro.sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_.jpg\" alt=\"in-car pollutants\" width=\"1305\" height=\"803\" title=\"\" srcset=\"https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_.jpg 1305w, https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_-300x185.jpg 300w, https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_-768x473.jpg 768w, https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_-1024x630.jpg 1024w, https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_-356x220.jpg 356w, https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_-696x428.jpg 696w, https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_-1068x657.jpg 1068w, https:\/\/carro.co\/sg\/blog\/wp-content\/uploads\/2017\/07\/Risk-posed-by-cars-www.vpcrc_.com_-683x420.jpg 683w\" sizes=\"auto, (max-width: 1305px) 100vw, 1305px\" \/><figcaption id=\"caption-attachment-6728\" class=\"wp-caption-text\">www.vpcrc.com<\/figcaption><\/figure>\r\n\r\nMost pollutants come from exhaust fumes. The walls between the car\u2019s engine and the interior of the car aren\u2019t as thick as we think. The engine emits gases that leak into the car\u2019s interior. You may think that opening the windows will prevent a buildup of these emissions, but it also allows emissions from other cars to enter your car.\r\n\r\nPolluted air makes its way into the car via air vents or open windows and recirculates them inside the car. On the other hand, keeping the windows closed slowly also escalates the buildup of your own engine\u2019s emissions as the levels of some pollutants are higher inside the car, compared to one the roads.\r\n\r\n<strong>Did you know that the \u201cnew car smell\u201d is a brew of over 300 chemicals (many of which are toxic)?
