Air pollution in India is a serious issue with the major sources being fuelwood and biomass burning‚ fuel adulteration‚ vehicle emission and traffic congestion.[1][2] India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest after China and the United States.[3] A 2013 study on non-smokers has found that Indians have 30% lower lung function compared to Europeans.[4] The Air (Prevention and Control of Pollution) Act was passed in 1981 to regulate air

Water Pollution Solutions Water pollution has been around ever since any of us can remember! What we need to look for now are water pollution solutions to help salvage our planet. So read on to know about some water pollution solutions... Water pollution is a problem that isn’t new to us. Water pollution has been around since time immemorial‚ though the severity of the problem has only recently struck environmentalists the world over. Although there are a lot of strict laws in the United States

Water pollution is the contamination of water bodies such as lakes‚ rivers‚ oceans and beaches. This occurs when large factories dump their waste products into the water. Water has the ability to carry many pathogens and bacteria. Because of this‚ water is responsible for many deaths and illnesses. This fact was discovered a long time ago when many people fell sick‚ and after tests‚ it was realized this was because of the drinking water. People‚ even back in the ancient times‚ would suddenly become ill

of the centrifuge increases. The G-force increases as the speed of the centrifuge increases. Which is likely the best speed to separate the components of this soil sample? Why? The best speed to seperate the components of this soil sample would be 5000 rpm because there are only two layers so the soil is more separate in that speed. Describe in which layers you are likely to find the organic matter‚ gravel‚ sand‚ silt‚ and clay at the following speeds:

Report –Soils Soil ph Soil texture Soil organic matter Soil water retention Two soil samples were consistently used for all four test completed below. The first is labelled as Valley A‚ and was obtained from a field which has been known to be uncultivated for 10 years in the valley. Valley B was obtained from a domestic garden‚ under a Magnolia tree in the same region. At times when a third sample was tested‚ the source will be indicated. Soil texture

Abstract: The appropriate scope of a geotechnical investigation is a function of the type of proposed land use or project‚ the soil/ geologic conditions of the project site‚ and type of permit or approval sought. The geotechnical consultant is responsible for targeting the scope of their investigation‚ testing‚ analyses‚ and documentation to balance these factors. References are

Article Summary Effects of earthworms on soil Earthworm is the common name for the largest members of Oligochaeta in the phylum Annelida. They combine bilateral symmetry and corresponding external and internal segmentation. This phylum consists of more than 17‚000 modern species of worms including earthworms‚ ragworms‚ and leeches. They are found in marine environments from tidal zones to hydrothermal vents‚ in fresh water‚ and in most terrestrial environments. They generally do not occur

Soil Porosity & Density Objective: To determine if the porosity of soil is related to the density. Hypothesis: I think that that the porosity of soil is related to the density because the higher the density of the sand the lower the porosity of the sand‚ which are both componets for the water to rise. Materials: • Sand and Loam samples • 2 large containers • Plastic cups • Water • Scale Procedure: Loam 1) The loam without the water was fresh ‚ it had different shades of black‚ and
