Transportation as a Source of Air Pollution
STRATEGIC APPROACH TO REDUCING VEHICLE EMISSIONS IN NIGERIA: ROLE OF FLEET OPERATORS.

BEING A LECTURE PRESENTED BY ENGR. BG IBRAHIM fwc ACM (SED) AT SAFETY MANAGERS TRAINING PROGRAMME AT FRSC ACADEMY, JOS ON THE 28TH AUGUST,2009.

INTRODUCTION

1. In developed and developing countries, the history of air pollution problem has typically been high levels of smoke and sulphur dioxide arising from the combustion of sulphur-containing fossil fuels such as coal for domestic and industrial purpose.[i] Industrial development and the use of fossil fuels have affected the world climate adversely. In Nigeria epileptic power supply has brought about the use of diesel and petrol powered generators virtually in all homes

2. The transport induced environmental pollution in Nigeria, is further compounded by recent influx of motorcycles and tricycles, most of which have 2-stroke engines. Equally, the importation of used vehicles and lack of vehicular emission control also contributed to the high level of pollution in the atmosphere. Petrol and diesel engine motor vehicles emit a wide variety of pollutants, principally carbon monoxide (CO), oxides of nitrogen (NOx), volatile organic compounds (VOCs) and particulates, which have an increasing impact on air quality. In addition, photochemical reactions resulting from the action of sunlight on nitrogen dioxide and volatile organic compound from vehicles leads to the formation of ozone, a secondary long range pollutant, which impacts in rural areas often far from the original emission site. Acid rain is another long range pollutant influenced by vehicle nitrogen oxide emissions. That is why vehicle emission pollution problems are worsening in countries where there is no adequate legislation towards its control.

3. It is for this reason that this paper takes a look at types of vehicular pollutants, causes of pollutants in vehicles and their effects. The paper will identify methods of controlling vehicular emission, the

    With this goal of safety on our minds, I believe the bottom line of the emphasis on safety could be considered to be the training that each of us receives in our first weeks on the job as well as the training provided on a regular basis throughout each year of our employment with M-Global, so that we are always aware of how to operate in a safe manner. The training vehicle gives the company the mechanism to provide each of you with the means to become aware of the elements of safety that relate to the specific needs and requirements of your own particular job. Therefore, at this time I have come to the conclusion in the process of the new corporate emphasis on safety to our particular branch that we need to give much greater scrutiny and analysis to the way we can prevent accidents and emphasize the concern of safety at every stage of our operation for every employee. Toward this end, I have asked the training coordinator, Kendra Jones, to assemble a written training program that will involve all employees which will be implemented beginning no later than June of this year. When the plan has been written and approved at the various levels within the office, I will conduct a meeting with every department in order to discuss all details of the safety program.…

    Firstly, vehicles are one of the leading causes of pollution. They burn high amounts of fuel and release toxin gases; for instance, during the eighteenth century, in London, this resulted in an increase of carbon dioxide in the air, and citizens had to wear face masks to avoid getting sick. Nowadays, engineers have made gasoline and electric powered cars which are economically friendly, and burn less fuel. Furthermore, local travelers who travel as far as going to work, school or shopping or more should only use four cylinders or less powered vehicles to release less CO2 into the atmosphere.…

    The significant air pollution problem in the Los Angeles Basin has been one of the most severe environmental issues that concerned the society. Due to the American tradition, public transportations are not so commonly used; therefore, a majority of the individuals owned a car. The most commonly used transportation is the convenient motor vehicles that are driven everywhere. With the high volume of traffic daily, the tremendous amount of air pollution that is produced by highly-polluted vehicles are growing at an exponential rate…

    Fossil fuel emission from motor vehicles as an outdoor air pollution produces pollutants in the air which leads to negative impacts on human health. (Climate Change and Health, 2010). These pollutants mainly include carbon dioxide (CO2) and nitrogen dioxide (NO2). The toxic pollutant nitrogen dioxide is ejected in the air during the process of combustion and it leads to numerous health issues especially on young children. Studies have found that “long-term exposure to NO2” increases the number of children who attracts asthma, furthermore, nitrogen dioxide have also shown to slow down or stop the growth of lungs of young children. (Air Quality and Health, 2011). On the other hand, carbon dioxide have known to affect the climate through trapping heat and energy. Therefore, fossil fuel emission indirectly affects the change of global climates which then leads to health issues.(Risks and Response, 2003). One of these issues is that extreme heat causes thousands of deaths. Secondly, extreme heat causes pollen in air to be more than usual, which could trigger asthma. Furthermore, increased temperature extends to lives of female Anopheles which is a species of mosquitoes that transmits Malaria. (Climate Change and Health, 2012). Therefore, fossil fuel emission directly and indirectly attributes to numerous health issues especially on young children.…

    When a car’s engine is running, several different types of gasses and particles are emitted that can have detrimental effects on the environment. Of particular concern to the environment are carbon dioxide, a greenhouse gas; hydrocarbons -- any of more than a dozen volatile organic compounds, some of which are known carcinogens; nitrogen oxides; sulfur oxides; and particulate matter, tiny particles of solids, such as metal and soot. Other emissions that affect human health and create smog include ozone and carbon monoxide. (See Reference 1) The good news is that despite the increase of vehicles on the road, air quality today is actually better than it was in the 1970s, thanks to the 1970 Clean Air Act. In fact, lead emissions from cars have been almost completely eradicated because of the phasing out of leaded gasoline. (See Reference 2, page 2)…
