Air pollution – contaminants or substances in the air that interfere with human health or produce other harmful environmental effects. Read our “What is Air Pollution?” article for further information. Alternative energy – usually environmentally friendly‚ this is energy from uncommon sources such as wind power or solar energy‚ not fossil fuels. Alternative fuels – similar to above. Not petrol or diesel but different transportation fuels like natural gas‚ methanol‚ bio fuels and electricity. B

Most water pollutants are eventually carried by rivers into the oceans. In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight‚ for example. The highest toxin

POLLUTION!!- IS THERE A SOLUTION? Human Beings belong to a species that poisons its own habitat. If we think of our planet as a spaceship then we are the new and all other species are passengers. In general we behave irresponsibly .Earth’s atmosphere forms a protective cocoon around our spaceship‚ storing and recycling essential elements such as carbon and oxygen. Humans fill the air with pollution that turns the rain acidic and threatens to alter the climate pollution from and fossil and nuclear

EFFECTS OF SOIL EROSION IN THE PHILIPPINES Soil erosion is happening everywhere in this world. Especially near the water area and maybe it is happening below where we stand. One my grandparents told me‚ that one time when they were young a typhoon with its devastating rain hit manila. Because they were near river‚ because of the heavy rain without warning the soil beneath their home collapse and their home was wash away in the river. And it said to be the cause of the collapse of the soil was the

Vehicle Pollution Introduction Urban areas - both developed and developing countries‚ this predominately mobile or vehicular pollution that contributes to air quality problems. All motor vehicles exhaust fumes coming out of the tailpipe when the engine is running mostly through the air pollution issue. Tailpipe emissions of vehicle engines burning fuel‚ the products are emitted from vehicle exhaust system. Vehicular pollution is the worst thing about that as vehicular emissions at ground

products‚ causing unsustainable environments. Cities are sources of air‚ water and soil pollution. Light and noise pollution are now known to adversely affect urban people. The role of urban heat islands and air pollution‚ PM2.5 and ozone‚ on human health is beginning to emerge. Lack of green space may have psychological effects for urban dwellers. We began to explore the nature of the urban environment and pollution on human health and well-being at UEP2010 in Boston in June of 2010. This very successful

GAS WELDING Gas welding is a process that use fuel gases and oxygen to weld and cut metals. Uses: 1-welding and cutting metals 2-in Stone Work for flaming 3-in the glass industry for fire polishing 4-in jewelry production How we use it : The apparatus used in gas welding consists basically of an oxygen source and a fuel gas source it’s pumped through hoses and get out to cut or weld the used metal and there are two cylinders one of them contain oxygen and we can control

Typical pollutants include: • Oxygen-demanding waste: materials that produce a high BOD [Fig. 11.2‚ Keller‚ 2000]

One of the dilemmas concerning our environment is saving wild life creatures. Cutting down trees is killing their habitat and ways of living. How would you like it if someone came into your neighbourhood and started bulldozing the houses down? Many living species have died because of the habitat changes they have to go through. Many oceans and other water bound areas in the world are being polluted by human waste. It’s killing all water creatures and making water unsanitary. If you really think about
