non-smokers and the dismay of those for whom a cigarette is a permanent extension of the lips. Tobacco smoke contains carbon monoxide‚ a gas which – if inhaled – can severely reduce the oxygen carrying capacity of the blood. It does so by combining with the blood pigment haemoglobin and preventing it from carrying the oxygen it was supposed to. This action of carbon monoxide displays one great advantage of the ban on smoking in public places. People standing next to the smoker will‚ against their

particles‚ liquid droplets‚ or gases. In addition‚ they may be natural or man-made. Pollutants can be classified as primary or secondary. Usually‚ primary pollutants are directly emitted from a process‚ such as ash from a volcanic eruption‚ the carbon monoxide gas from a motor vehicle exhaust or sulphur dioxide released from factories. Secondary pollutants are not emitted directly. Rather‚ they form in the air when primary pollutants react or interact. An important example of a secondary pollutant isground

Experiment 8: Hydrogen Phosphate Buffer Systems Purpose The purpose of the lab was to create a buffer solution and observe the capacity of the phosphate buffer system. Also‚ the experiment was meant to provide experience with the calculations and mathematics involved in creating the buffer solution. Finally‚ the lab was designed to provide an insight and appreciation for the necessity and complexity of buffers in our physiology and in the environment. Procedure No deviations were made from

A Seminar Report on “CATALYTIC CONVERTER” PREFACE Catalytic converter is most effective device which converts harmful gases due to engine exhaust into eco-friendly gases. In this report‚ we have tried to bring into focus imports of reducing air pollution and why catalytic converter is necessary in automobile. We also tried to bring advance technology found out now a day for reducing air pollution. By best effort‚ we try to focus necessity of subject. We hope our report is one

led by the exhaust gases from the vehicles. These exhaust gases contains carbon monoxide (CO) and hydrocarbons in high proportions which adversely increases the Global Warming and Green House Effect. The goal of this paper is to introduce a method which adsorbs the hydrocarbons and absorbs carbon monoxide led by the vehicles thereby controlling the Global Warming and Green House Effect. The absorption of carbon monoxide is done by using cuprous salt and adsorption of hydrocarbons is done by using a

were further more developed by two engineers called John Mooney and Carl Keith. The catalytic converter is placed under the front seat by most carmakers. (See photo) ) Cars produce a lot of harmful emissions‚ but the main ones are: carbon monoxide which is a piousness gas‚ hydrocarbons which is mostly produced by evaporated‚ unburned fuel and nitrogen oxides‚ which cause irritation to human mucus membranes. But how does a catalytic converter help reduce the emissions? To answer this question

sensitivities‚ like those who have asthma‚ or the elderly‚ and also athletes are especially vulnerable to unhealthy levels of air pollution. There are many kinds of air pollution. The ones I want to talk about are the ozone‚ acid rain‚ carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore‚ ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can

cancer-causing substances. Tar is brown and sticky posing stains on fingernails‚ teeth‚ and lung tissue. Carbon monoxide This gas is deadly if consumed in large amount because it replaces oxygen in the red blood cell. Red blood cell contains haemoglobin that transports oxygen molecules from the lungs to other parts of the body. On the other hand‚ haemoglobin has higher affinity to carbon monoxide as compared to oxygen. This shows that less oxygen reaches the brain‚ muscles‚ heart and other organs Hydrogen

This action of carbon monoxide displays one great advantage of the ban on smoking in public places. People standing next to the smoker will‚ against their wishes‚ be inhaling the tobacco smoke emanating from the tip of the cigar or cigarette as well as that exhaled by the smoker. Thus‚ large quantities of carbon monoxide will be entering the “victim’s” blood stream

AIR POLUTION Problem The first thing people see‚ in the morning‚ when they walk outside is the sky or the colored sun. Is this world giving us the privilege of seeing the natural colors of the sun through all the layers of pollution within the air (Dinanike 31)? Not only are beautiful sights such as this hidden behind the pollution this world causes everyday‚ but an increase in diseases‚ infections and death occurs. What causes pollution? What can we do to prevent it‚ and get rid of it? Is it fair
