The use of lead as a petrol additive has been a catastrophe for public health. Leaded petrol has caused more exposure to lead than any other source worldwide. By contaminating air, dust, soil, drinkingwater and food crops, it has caused harmfully high human blood lead levels around the world, especially in children (1). Tetraethyllead was first added to petrol in 1922, to improve engine perform...

Huge amount of low-grade heat energy is discharged to the environment by vehicular engines. Considering the large number of vehicles in the world, such waste energy makes great impacts to our environment globally. Organic Rankine Cycle (ORC), which uses an organic fluid with a low boiling point working medium, is considered as the most promising technology to recover energy from low-grade waste...

The depletion rate of conventional petroleum fuels is very fast. Gasoline used as fuel in the SI engine. Emissions from this cause environmental pollution because it produces harmful emissions for environment such CO2, CO, HC, and NOx. Liquefied gas (LPG) has physical chemical properties that make a favorable IC engines. It can be alone or combined with gasoline some minor engine modifications....

The increased travelling of today makes nodes along travelling routes more and more important. This is very much the case of petrol stations. They constitute important nodes in the road network, filling up thirsty fuel tanks and hungry stomachs, guiding road users and providing vehicle-services. In this thesis the role of the petrol station for road users was investigated in order to find out i...

Objective: Exposures to petrol vapours have been shown to affect functioning of different systems of the body. The effect on lung function is largely unexplored in Africa. We aimed at studying the effect of exposure to petrol vapours on pulmonary function among petrol pump workers. Method: A cross-sectional survey using modified Medical Research Council questionnaire was conducted and spirometr...

It has been suggested that fumes from diesel engines make an important contribution to atmospheric pollution. This is probably because they are sometimes highly irritant and sometimes very smoky. It is well known that, because of their comparatively low carbon monoxide content, these fumes are much less lethal than those from petrol engines. The leading work on diesel fumes has been done by the...

Petrol scarcity is a malady and a serious economic problem in Nigeria. Successive governments have, often times, used it as a case for political advances, yet petrol scarcity remained an undefeatable macroeconomic monster in Nigeria. The need for petrol, its availability and affordability is obviously important especially as the risks and its attendant effects are undesirable. Thus, this invest...

Lung function tests have been of increasing interest in the use for qualitative and quantitative evaluation of pulmonary function in patients with abnormalities of cardiorespiratory system (1). Petroleum refining products are constituted by cycloalkanes, straight and branched chain alkenes which are continued source of pollution in various occupational settings (2). With the increasing use of p...
