Do You Know How Dangerous The Car Exhaust Is To Your Health? by Nobody: 9:10pm On Oct 01, 2013 |
The adverse health effects of car exhaust are pervasive and difficult to measure. Many people are exposed to exhaust emissions every day in different ways like vehicles running on diesel and petrol. How are people exposed to exhausts? Breathing in fumes from car exhaust; and this could increase the risk of a heart attack for those already battling a heart disease. A heart attack occurs when the flow of oxygenated blood to a section of the heart’s muscles has been blocked. Inhaling fumes in heavy amounts could trigger a heart attack, according to a team of researchers from London School of Hygiene and Tropical Sciences. Where are people exposed to exhausts? 1. At work : People with the some of the highest exposures at work include truck drivers, heavy machinery operators, railroad and dock workers, garage workers and mechanics. Some farm workers may also spend a lot of time around diesel exhausts. 2. While traveling: Exposure to fuel exhaust may be higher when in a vehicle, especially when traveling on roads with heavier truck or bus traffic. Commuting to and from work is a potential source of fuel exhaust exposure for many people. One particular area of concern is children’s exposures to fuel exhaust and other pollutants while riding in school buses, as the buses themselves typically run on diesel fuel. 3. Where they live and play: People can also be exposed to fuel exhaust in areas where they live and play, although this is typically at lower levels than in the workplace. Exposures are highest where traffic is heaviest such as along major highways and cities. How are exhaust fumes emitted? Exhaust gas is emitted as a result of the combustion of fuels such natural gas, petrol, diesel fuel, fuel oil or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe. The largest part of most combustion gas is nitrogen,water vapour and carbon dioxide. A relatively small part of combustion gas is composed of undesirable, toxic substances such as carbon monoxide from incomplete combustion. Diseases likely to be caused through the inhalation of car exhaust fume are: 1.Cancer: Vehicles emit numerous carcinogenic chemicals. Diesel contains benzene, formaldehyde, and 1,3- butadiene — all these are well recognized carcinogens. It was observed that vehicle emissions account for as many as half of all cancers attributed to outdoor air pollution. 2. Cardiovascular diseases: Death and hospital admissions for myocardial infarction, congestive cardiac failure and cardiac arrhythmia increase with increase in the concentrations of particulate and gaseous pollutants. As concentrations of airborne particles increase, those with cardiovascular disease may experience increasing severity of symptoms, rates of hospitalization, and mortality. 3. Asthma attack: Diesel exhaust is especially dangerous, containing nearly 40 hazardous pollutants. The mixture contains carbon particles that are exceptionally small in size, less than one micron. These fine particles may be deeply inhaled into the lung and carry with them a collection of attached hazardous compounds. Diesel emissions increase the severity and duration of asthma attacks. What can be done to minimize exposure to exhaust fumes? Since components of vehicle exhaust fumes are carcinogenic, exposures to both diesel and gasoline exhaust constitute a large proportion of our exposures and must be minimized. *Cars and trucks should not run unnecessarily idle and people should turn off their motors when they are not in their vehicles and children should never be allowed to pump gas. *Exhaust exposure can also be avoided by decreasing the amount of time that is spent where machines are running. *People should not exercise along busy streets or highways. *You can also reduce exhaust exposure by closing your car windows while driving in moderate and heavy traffic.

This is rapidly becoming a serious issue in Nigeria due to the reckless abandon of automobiles, motor bikes, keke napeps, electric generators etc emitting toxic fumes all over the place. Recently in Lagos, several members of a church choir having a night vigil all suffocated and died of carbon monoxide poisoning inside the church while running the electric generator inside the church because it was raining outside. Here is an excerpt with more convincing detail. Happy reading. Carbon monoxide poisoning occurs after enough inhalation of carbon monoxide (CO). Carbon monoxide is a toxic gas, but, being colorless, odorless, tasteless, and initially non-irritating, it is very difficult for people to detect. Carbon monoxide is a product of incomplete combustion of organic matter due to insufficient oxygen supply to enable complete oxidation to carbon dioxide (CO2). It is often produced in domestic or industrial settings by older motor vehicles and other gasoline-powered tools, heaters, and cooking equipment. Exposures at 100 ppm or greater can be dangerous to human health. Symptoms of mild acute poisoning include lightheadedness, confusion, headaches, vertigo, and flu-like effects; larger exposures can lead to significant toxicity of the central nervous system and heart, and even death. Following acute poisoning, long-term sequelae often occur. Carbon monoxide can also have severe effects on the fetus of a pregnant woman. Chronic exposure to low levels of carbon monoxide can lead to depression, confusion, and memory loss. Carbon monoxide mainly causes adverse effects in humans by combining with hemoglobin to form carboxyhemoglobin (HbCO) in the blood. This prevents hemoglobin from releasing oxygen in tissues, effectively reducing the oxygen-carrying capacity of the blood, leading to hypoxia. Additionally, myoglobin and mitochondrial cytochrome oxidase are thought to be adversely affected. Carboxyhemoglobin can revert to hemoglobin, but the recovery takes time because the HbCO complex is fairly stable. Treatment of poisoning largely consists of administering 100% oxygen or providing hyperbaric oxygen therapy, although the optimum treatment remains controversial. Oxygen works as an antidote as it increases the removal of carbon monoxide from hemoglobin, in turn providing the body with normal levels of oxygen. The prevention of poisoning is a significant public health issue. Domestic carbon monoxide poisoning can be prevented by early detection with the use of household carbon monoxide detectors. Carbon monoxide poisoning is the most common type of fatal poisoning in many countries. Historically, it was also commonly used as a method to commit suicide, usually by deliberately inhaling the exhaust fumes of a running car engine. Modern automobiles, even with electronically-controlled combustion and catalytic converters, can still produce levels of carbon monoxide which will kill if enclosed within a garage or if the tailpipe is obstructed (for example, by snow) and exhaust gas cannot escape normally. Carbon monoxide poisoning has also been implicated as the cause of apparent haunted houses; symptoms such as delirium and hallucinations have led people suffering poisoning to think they have seen ghosts or to believe their house is haunted.

since when I was born up till now the kinda smoke n exhaust id have inhaled alone can fill up two NNPC trailer tankers buh here am I today hale n healthy. the only sickness that happened to me twice this year was malaria n just two days they were gone n forgotten with just #700 lumartem n #50 paracetamol Everyone has one or two testimonies to share abou God's faithfulness over the months. I think our God deserves some minutes of praises from his people so before you leave home today dont forget to say "God thank you for your faithfulness" #Happy_new_month everyone 6 Likes 1 Share
