that build modern stramolites are photosynthesis. 6. What is ozone and how is it produced? Ozone screens out most of the ultra violet radiation from the sunlight. Ozone forms through the action of ultra violet radiation on oxygen in the upper atmosphere and many scientist reason that their layer could have formed only after oxygen from photosynthesis began to accumulate. 7. Why is the ozone important to life today? The ozone is important to life because it acts as a shield from the harmful

Air Pollution - The Causes & Effect . Defi-Air pollution‚ both indoors and outdoors‚ poses health risks to millions of Americans every day‚ contributing to asthma‚ emphysema‚ heart disease‚ and other potentially lethal conditions. Managing air pollution causes‚ and defending successful safeguards like the Clean Air Act‚ is critical to the human‚ economic‚ and environmental health of our communities. America’s power plants are our biggest industrial polluters. Each year they pump more

The demand and supply of refrigeration systems is increasing day by day with changing lifestyle. In last few decades with excess use of CFCs and HCFCs‚ we have degraded the environment to larger extent. This resulted into adverse effects such as Ozone depletion and Global warming. So technological development based on improvement in energy efficiency should be done. The modern systems include the technologies which are cost effective‚ energy effective and economically feasible. The new emerging

it could cause a major problem in the nitrogen cycle. Future air pollution effects do not look good for North Carolina. According to Clean Air Carolina‚ “as the region grows and climate change increases the number of hot summer days‚ ground-level ozone problems are expected to worsen” (“NC’s Air Quality”). Even though the Clean Air Act is in place to monitor air pollution levels‚ that is not enough to stop the possible damage of air pollution to our earth. Turning off the light switch after leaving

smoke‚ or more particularly‚ soot and ash‚ may coat plant leaves directly reducing photosynthesis by preventing light penetration or even by clogging stomatal openings. The pollutants involved in acid rain are sulphur dioxide‚ oxides of nitrogen‚ ozone and various volatile organic vapours given off from gasoline stations. Fossil fuels contain between 1% and 4% sulphur and consequently around 30 million tonnes of sulphur dioxide is emitted from the chimneys of Europe each year. It’s effect in high

air pollutants can be classified as ground level Ozone‚ Particulate matter‚ Carbon monoxide‚ Nitrogen oxides‚ Sulphur oxides and Lead. Ground level Ozone – these are formed by photochemical (in the presence of sunlight) reactions in the atmosphere between oxides of nitrogen (NOx) and volatile organic compounds. Some sources of ground level ozone are industrial plant emissions‚ motor vehicle exhaust etc. Many urban areas have high ozone level densities. Inhalation can trigger chest pain

Air pollution is caused by the presence of chemicals‚ particulate matter‚ or biological materials in the air which harms humans and other living organisms. It can also damage the natural environment. Air pollution causes depletion of ozone in the stratosphere which endangers human health as well as the Earth’s ecosystems. Air pollutants can be in the form of solid particles‚ liquid droplets‚ or gases. They could be natural or man-made. Pollutants can be classified as either primary or secondary
