are smaller so they don’t understand that the hot air that is blowing out at them is carbon monoxide. They think it cool for air to be hitting them. Another thing they schools should do is have all of the bus students wait inside if the bus company won’t turn off their engines so they are only exposed to the minimum bus pollutants. By doing this you won’t have as many students standing where the carbon monoxide is coming out. Schools could improve the health and intake of pollutants

is the fact that you save by not buying fuel for your private vehicle every day. Secondly‚ you are freed from the burden of finding a parking spot for your car. Moreover‚ by taking the bus you are partially contributing to the reduction of carbon monoxide in the air for a bus full of people causes less pollution than individual cars for each family would. However‚ taking buses can be time consuming because buses have to take the longest routes and halt at every bus stop. Furthermore‚ some passengers

do not break into houses in the middle of the night‚ letting people be at ease while they are at home. The second reason why country living is better is the lower pollution levels. With fewer people come fewer cars and factories belching carbon monoxide into the air. This results in the air being fresh and clean rather than noxious and dirty. In the country‚ most people do not throw trash all over the ground. The lands are beautiful and clean and all trash is in the garbage can‚ unlike the city

Carbon monoxide poisoning is one of the occupational toxic risk factors for not only myocardial infarction but also cardiomyopathy. Firefighters ’"chronic" occupational exposure to carbon monoxide results in increased blood concentrations of carboxyhemoglobin‚ even in nonsmoking firefighters; changes in cardiac serum enzyme levels in one study suggested myocardial (heart) damage.

Preformulation activities range from supporting identification of new active agents to characterizing physical properties necessary for the design of dosage forms. Critical information provided during the preformulation can enhance the rapid and successful introduction of new therapeutic entities for humans. Hence‚ preformulation studies are essential to characterize drugs for proper designing of drug delivery systems. The preformulation studies‚ which were performed in this project‚ include – identification
