Many people point to things like temperature in the classroom, the books being used, the availability of materials, the quality of the teachers, the condition of the schools and so forth.
The Clean Air Act sets numerical limits on the concentrations of a basic group of air pollutants and provide reporting and enforcement mechanisms. The effects of these laws have been very positive. In the United States between andcitizens enjoyed the following reductions in annual pollution emissions: The scientists unanimously recommended a smog threshold of 60 to 70 ppb after they conducted an extensive review of the evidence.
This is less strict than the scientific recommendation, but is more strict than the current standard.
Some industries are lobbying to keep the current standards Air quality in houston essay place. Environmentalists and public health advocates are mobilizing to support the scientific recommendations.
With it comes up to three-quarters of the black carbon particulate pollution that reaches the West Coast. Federal limits and pollution standards are set by the Clean Air Act. Health effects[ edit ] Due to air pollution causing more than one effect it is hard to attribute a condition only to air pollution or to say how much a given source is responsible.
However, it is believed that at least human deaths are attributable to air pollution and at least a quarter are due to transportation. Which are both also attributable to human technology application. There are also significant non-human deaths and effects. Asthma[ edit ] As air pollution increases, symptoms of asthma worsen.
Asthma's etiology is poorly understood and currently has no cure. There are many environmental factors that attribute to asthma. The main sources of environmental pollution are the burning of fossil fuels in the combustion engines, dust generated by traffic on road surfaces, and biomass used for cooking and heating.
In urban areas, there are high concentrations of particulate matter, nitrogen dioxide, ozone, and other volatile organic compounds and can make breathing more difficult.
The health effects of particulate matters with different diameters are related to the length of those particles staying in the atmosphere and the locations of infection in the respiratory tract  Young children who are exposed to air pollution are extremely vulnerable. One reason they are more vulnerable is because the average breathing pattern for an adult is 16 to 20 breaths per minute, while a 1-year-old child has a faster breathing pattern which is 20 to 40 breaths per minute.
Therefore, children will be inhaling more pollutants than adults. Many of the mothers exposed to PM2. These phthalates were detected in urine samples from pregnant women.
Some of the pollutants studied have been connected to asthma. It has been reported that people who live within 1. Carbon monoxideoxides of nitrogensulfur dioxideozoneleadand particulate matter are also associated with increased hospitalization and mortality due to cardiovascular disease.
Chromosomal damage is high among African American children and their mothers from Oakland, California who are exposed to traffic and regional ozone levels.
Also, those who live in the area of lower socioeconomic status have higher risk of cardiovascular diseases caused by PM 2. The prevalence of being exposed to secondhand smoke is higher in African American population and lower income population, especially in those who live below the poverty level.
Inhaled air pollutants damage the respiratory system and can lead to infections or cancer. Respiratory infections and cancer are related to each other. Having a respiratory infection raise the risk of cancer and vice versa.
Infections[ edit ] Even though the mechanistic association between air pollution and infections is still unclear and require further research,  some studies shows that the some air pollutants, including secondhand smoking, ozone O 3particulate matter PMand nitrogen dioxide NO 2may cause the infections.
CPSC mentions thattochildren under 18 month are affected by the lower respiratory tract infections which leads to 7, to 15, hospitalizations each year based on the EPA estimation.
Exposure to higher level NO2 or long term exposure to low level NO2 also leads to higher risk for infections. Small, invading organisms in human body, such as bacteriavirusesfungior parasites, can cause infections in the pulmonary system.
There are variety of infections because many different organisms can cause the infections. The prevalence of the bacterial infections is not equally distributed in terms race of and socioeconomic status. In the United States, bacterial pneumonia, caused by Streptococcus pneumoniae bacteria pneumococcus which enters human body usually via inhalation,  is significantly associated with morbidity and mortality among adults.
Indoor pollution such as tobacco smoking is responsible to lung cancer.Air Quality problems are some of the most complicated environmental issues we face in North Central Texas.
The Office of Environmental Quality’s Air Quality Program aims to promote healthy outdoor air for all residents by addressing the impact of City operations and actions on air quality.
Air Quality Nuclear energy protects air quality and the health of millions of people by avoiding the harmful emissions that cause acid rain and smog. Nuclear energy is by far the largest source of clean-air energy in the United States, generating more than 56 percent of the nation's emission-free electricity.
For years, people have said that Houston, one of the most heavily polluted cities in the United States, is also one of the cities with the heaviest monitoring of air quality in the country. Air Pollution Facts.
Everyone on earth knows that air pollution is hazardous to health.
The effects of air pollution can have devastating effects on your health and the environment. Here is an interesting way to analyze how air pollution is gradually causing so many deaths worldwide.
Jan 19, · Unfortunately, pollution is everywhere — even in the air we breathe and poor air quality causes a number of health problems.
Air Pollution: 8 Things You Should Know Air pollution has many sources – cigarette smoke, automobiles, and industrial chemicals are only a few things that pollute the air . Shop our selection of Air Quality Testers in the Heating, Venting & Cooling Department at The Home Depot.
