Mexico City's Air Pollution Crisis
The extent of industrialization and population density. Air Pollutants Sources of air pollutants Major sources of air pollution are natural sources and man-made source. Natural sources: Volcanic eruptions, forest fires, deflation of sands and dusts, storms, etc. Pollutants from natural sources Volcanoes: ashes, smokes, carbon dioxide dust and other gases. Land surface: salts spray from seas and ocean, dusts and soil particles from ground-surface.
Extraterrestrial bodies: cosmic particles and rays, chest produced due to bombardment of asteroid materials, comets etc. Man-made anthropogenic sources Industries, automobiles, agriculture, power plants, Blackwell Engl 11 Nov Air pollution effect on humans There's nothing quite like opening the door and breathing fresh, clean, air —but how clean is the air you're breathing right now? Unless you're a scientist with a chemistry lab at your fingertips, there's no real way of knowing.
The gases you're sucking up through your nose could be slowly killing you: according to the World Health Organization, around two million people die prematurely from the effects of polluted air every single year. Air pollution has both acute and chronic effects on human health, affecting a number of different systems and organs. It ranges from minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults, aggravating pre-existing heart and lung disease, or asthmatic attacks. What exactly causes this major environmental issue and what can we do about it?
Let's take a closer look! Air pollution is a gas or a liquid or solid dispersed through ordinary air released in a big enough quantity to harm the health of people or other animals, kill plants or stop them growing properly, damage or disrupt some other aspect of the environment, or cause some Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur Read Informative Speech about air pollution Topic: Air pollution Specific Purpose: To inform my audience about two causes and one effect of air pollution.
Central Idea: The main two causes of air pollution and an effect of it in human body. Introduction: Hello, all of my audience, I want to start my speech by asking you guys that, How many of you know about Air pollution? Whether its transportation, factory smoke, burning coals, etc. Cause 1: There many causes out there that leads to air pollution and one of them is from transportation. Austria kB Land Use within the area of Mexico City is greatly distorted; the charts below indicate some mismanaged concept implemented by the district government.
The following graphics show the distribution of land uses fig. The remaining facilities are spread throughout the other districts. Residential Distribution. Major concentrations of habitation in were Iztapalapa with The remaining areas are spread throughout the other districts. This lowered partial pressure pO 2 does have significant effects. For example, people breathing at these altitudes require more red blood cells and their blood viscosity changes significantly. Because less oxygen is available, combustion processes likewise cannot take place adequately. Such rich mixtures, on the one side, reduce the emission of nitrogen oxides, but on the other side, it enhances the emission of carbon monoxide COhydrocarbons, and volatile organic compounds VOC.
Changes in engine design, the addition of catalytic converters or after burners and careful tuning considerably would reduce the major pollutants in exhaust gases. The difficulty with these approaches is that they often work well on a test bed with warm engines under suitable operating conditions, but are not so effective in poorly maintained vehicles operating under stop-start city cycles fig. Under these aspects, this environment of about 21 mio inhabitants, most of them younger than 25 years of age, crowd together to produce not only one of the most densely populated cities but also one of the most severe air pollution scenarios on earth.
The climatic conditions of the state of Mexico are quite diverse; they range from a semiarid belt in the far North to a rather tropical environment in the South. The climate is generally dry, but thunderstorms are frequent and intense from June through October. Winters are slightly cooler than summers and have a more semiarid character - see table. The global wind-distribution charts reveal the general trends among the most distinct seasons January and July average - see fig. During the winter months a very persistent high pressure system resides over the south-eastern Pacific of the northern hemisphere.
This enables a weak flow of moderately tempered air synoptic flow from the south into the highlands of Mexico. The geographical conditions of Mexico City with its northern opening traps the air that are pushed by turbulent flow as a result of the synoptic flow from the north towards the southerly located mountain chain favoring an inversion zone. As mentioned previously, the location of heavy industry at the northern outskirts of the City keeps pushing their exhaust gases into the metropolitan area, which further aggravates the already tense situation present due to exhaust emissions of the automotive fleet. The summer months, experience a stronger synoptic flow from the south, intensive sunshine, and the absence of inversed atmospheric strata by lifting the trapped masses of air and thereby cleansing the daily accumulating toxic cocktail.
And still, often the winds crossing the southern mountain chain run over the cushion of firmly residing air in the valley. Like in winter, the resulting vortex further below the mountain chain pushes the air back from the northern end into the valley towards the south. The only easing effect during the summer months are the wash-out effects due to rain and lifting of the air strata during intense sunshine. Up to date, fossil fuels are the primary energy source for the Mexico's industry and technology based society. Yet their combustion, especially in automobiles, release incompletely burned chemicals and oxidized species known as primary pollutants into the atmosphere. The dangers they pose range from eye and throat irritation to global warming.
Many of the primary pollutants undergo further reaction under the influence of sunlight. The products of these photochemical reactions are called secondary pollutants. Primary and secondary pollutants, along with aerosolswhich are suspended fine particles such as water droplets, dust, and soot, contribute to the brown haze observable as smog fig. At these altitudes, the partial pressure of oxygen pO 2 is far lower than at sea level, thus combustion is far from ideal.
Most of the energy consumed in this city is related to urban transportation. A very important source of air pollution is gas exhaust from private vehicles. The image on the right shows drastically how the prevailing atmospheric conditions affect Mexico City. A change in the temperature stratification within higher altitudes of the atmosphere hinders exhaust gases to escape the valley.
Such situations and the massive generation of toxic gases can alter the trapped air into a harmful cocktail fig. Under certain conditions, the contribution of emissions from the previous day can accumulate with those of the present day. We use cookies to give you the best experience possible. Words:Paragraphs: 25, Pages: 9. Parent topic: Air Pollution Renewable energy. General information about the problem: As the vehicle population reached more than million, numerous cities experiencing rapid industrialization started to suffer from air pollution.

Describe your solution: Hydrogen should replace gasoline. Advantages: Reduction in air pollution due to zero emissions Hydrogen is abundant renewable source Hydrogen is expensive to produce Hydrogen refueling stations construction require big amounts of money VI. Conclusion-Recommendation: Mexico City is often said to be the most polluted city in the world. Mexico City is home to over 3 million stray dogs. Their feces dries in the heat and their particles get picked up in the air. Because of this, Mexico is one of the only places that you can catch Hepatitus or desentery just by walking down the street.
These are sulfur dioxide, nitrogen dioxide and total suspended particles or TSPs. TSPs are tiny particles of anything ranging from dust to heavy metals which lodge deep in the lungs and cause major damage. While some cities in China scored worse with pollutants such as TSPs, Mexico was worst when taking into account the overall number of children The rest of the paper is available free of charge to our registered users.
