No. 44 - Fall 1998 Light Pollution Villains of Lighting Heroes of Lighting Light Pollution and the U.S. National Science Education Standards Activity 1 ... Resources It is an unfortunate fact of today's life that most people are growing up unable to see the stars that our grandparents knew so well. The prime night sky exists only in pictures or at a planetarium. This is true not only in cities but also in suburbs and in rural areas where street lamps and other sources of "light pollution" have obscured our view of constellations, meteor showers, and even the planets. Indeed, many children and adults say after viewing the night sky for the first time in a really dark area away from a city that "it looks just like this in the planetarium." We have lost our view of the stars, and we have mucked up our nighttime environment as well. Such a loss might be acceptable if light pollution were the inevitable price of progress, but it is not. Most sky glow is unnecessary. The light that obscures our view of the night sky comes mainly from inefficient lighting sources that do little to increase nighttime safety, security, or utility. They produce only glare and clutter, costing more than one billion dollars annually in the U.S. alone. The Earth at night For astronomy and science, the impact has been even more dramatic. Astronomers require observations of extremely faint objects that can be made only with large telescopes at sites free of air pollution and urban sky glow. For example, scientists interested in how the universe was formed may study the light of galaxies and quasars at enormous distances from Earth. These images offer information about faraway corners of the universe, helping us understand how our own world was formed. Yet, after traveling countless lightyears, the light from these objects can be lost at the very end of its journey in the glare of our own sky.

Light Pollution comes in several flavors... each with its own negative effects. These are: Sky Glow ...light wastefully escaping into the night sky and causing a glow over urban/suburban areas. Glare ...light shining dangerously out into peoples eyes as they walk or drive by. Light Trespass ...unwanted light shining onto a neighbors property or into their home.

Water Pollution So that you can become a water pollution expert, first we'll investigate different kinds of water pollution. And when you're ready, you can help clean up an oil spill! One kind of water pollution, which is usually the most common, is called CONVENTIONAL and is made up of conventional pollutants. Conventional pollutants are solid particles and matter found in our water. Most of the pollution you can see is conventional. Cans, bottles, paperjust about anythingcan be a conventional pollutant. You can see conventional pollutants in the picture above. Conventional pollutants cause a wide variety of environmental problems. The solids suspended in the water can block the sun's rays, and this blocking disrupts the carbon dioxide/oxygen conversion process. This process is vital to an aquatic food chain. Sometimes the solid pollution is so bad, the water becomes unusable to humans and animals. The best way to remove conventional pollutants is to run the water through a treatment plant. In treatment plants the water is skimmed, run through several filters, and settled. This removes about 60 percent of the pollutants. The remaining pollution is decomposed by tiny pollution-eating microorganisms. Microorganisms are living things that are so tiny you need a microscope to see them. Another type of pollution is called NON-CONVENTIONAL and is made up of non-conventional pollutants. Non-conventional pollutants are more dangerous to the environment than conventional pollutants. Non-conventional pollutants are dissolved metals, both toxic (harmful) and nontoxic (not harmful). Many factories dump these pollutants into the water as byproducts of their production process. The most devastating type of non-conventional pollution is an oil spill. More than 13,000 oil spills occur each year in the United States.

77. Light Pollution Experimental image modeling light pollution in the continental United States. This is based on the location and population (1990 census) of significant U.S. http://laps.noaa.gov/albers/slides/ast/places.html

Skyglow / Light Pollution JPEG GIF TIFF Experimental image The image is a plot of expected sky glow at the zenith. Light pollution from a city is assumed to be related linearly to the population and the inverse 2.5 power of the distance (as in Walker's law). The relation used here is I = 11300000 x population x r^-2.5, where I is in nanoLamberts and r is in meters. This is corrected for earth's curvature at large distances (this necessity was pointed out by Roy Garstang). This is currently done by calculating what fraction of the air molecules and other scatterers over the observer lie within the earth's shadow as seen from the city. The overall scale height for these scatterers (defined as the incremental height required to see a drop off by a factor of 2.718) is currently set to 4000m. This is less than the "clear air" value of 8000m to account for a modest amount of aerosols. A number of ideas and equations used come from publications by Roy Garstang The assumed radius of each city is a function of city population, ranging from 2.5 km to 24 km. Walker's law applies if we are outside the city radius. Inside the city radius, the sky glow increases linearly toward the center by another factor of 2.5. A value for the natural sky glow is added onto the light pollution contribution. The natural sky glow is assumed to be equal to 60 nanoLamberts (V = 21.9 mag / sq sec) at solar minimum. The last step in arriving at a pixel value is scaling the brightness with respect to the logarithm of the sky glow. The brightest city has pixel values of (255,255,255), and the darkest country site has pixel values of (42,52,67). The calibration bar is intended to linearly represent the sky brightness in terms of magnitudes per square arcsec.

See Also: More Information Advertisement Air Pollution Printer-friendly version Email this page Make text bigger What is air pollution? Air pollution is made up of many kinds of gases, droplets and particles that reduce the quality of the air. Air can be polluted in both the city and the country. In the city, cars, buses and airplanes, as well as industry and construction may cause air pollution. In the country, dust from tractors plowing fields, trucks and cars driving on dirt or gravel roads, rock quarries and smoke from wood and crop fires may cause air pollution. Ground-level ozone is the major part of air pollution in most cities. Ground-level ozone is created when engine and fuel gases already released into the air interact when sunlight hits them. Ozone levels increase in cities when the air is still, the sun is bright and the temperature is warm. Ground-level ozone should not be confused with the "good" ozone that is miles up in the atmosphere and that protects us from the sun's harmful radiation.
