BACKGROUND Blood lead concentrations (B-Pb) were measured in 3 879 Swedish school children during the period 1978-2007. The objective was to study the effect of the proximity to lead sources based on the children's home and school location. METHODS The children's home address and school location were geocoded and their proximity to a lead smelter and major roads was calculated using geographi...

In our current research work,we investigated the DNA interaction with Petrol,to obtain a better understanding of the DNA response when subjected to Cyclic Voltammetry

Gasoline engines remain a potential source of atmospheric pollution. Dual fuel combustion was under investigation to cope with exposure pollutants. Investigations on emission parameters and engine performance for single-cylinder four-stroke petrol are carried out using multicriteria decision-making method (MCDM). Bar charts constructed three in function temperature consumption different blends....

Blood lead levels were determined in preschool children residing in Urban areas of Rawalpindi city. Of 92 (50 males and 42 females) children aged one to 5 years were included in the study. Blood lead levels ranged from 7 micrograms/dl to 34 micrograms/dl (mean 18.8 micrograms/dl). The mean lead levels were slightly higher in males (20.3 micrograms/dl) than in females (17.2 micrograms/dl) and ov...

Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon f...

An experimental study is carried out to investigate engine performance parameters and methods of reducing emissions from spark ignition engine. Fuel efficiency is one of the major concerns for the users, the designers and the manufacturers of internal combustion (IC) engines, The effect of increasing the temperature of cylinder liner has the advantage of reducing the specific fuel consumption b...

In 2001-2002 the UK began taxing vehicles according to CO2 emission rates. Since then, there has been a significant increase in consumer choice of small cars and diesel engines. We estimate CO2 reductions and air quality impacts resulting from UK consumers switching from petrol to diesel cars from 2001 to 2020. Annual reductions of 0.4 megatons (Mt) of CO2 and 1 million barrels of oil are estim...
