Case Study Of Chlorella Vulgaris

When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source. In some cases even killing an entire species.

Bioremediation takes simple living organisms that can thrive in an extreme environmental conditions(environmental mishap) that would otherwise be hazardous to complex organisms to resolve the issue by consumption or decomposition.

it has in store for the future if things do not improve. It will also explore

Most people are surprised to learn that their bodies are contaminated with heavy metals. This is a little-known problem that has grown into a widespread issue. There are many different ways your body becomes contaminated with heavy metals, such as through the type of cookware you use, the tap water you drink and the fillings you have in your teeth. Fortunately, there are natural ways to cleanse your body of these harmful toxins, such as with chlorella. This is an algae found in nature and is oftentimes used in integrative medicine by naturopathic doctors in Arizona.

The outcome of this lab proved for the prediction to be true. The organisms in the aquatic chamber died out and the water quality slowly deteriorated before the lab ended. Although the organisms eventually died, there was a time when the aquatic chamber was able to support life. The aquatic chamber had its own food chain where the fish ate the plant to stay alive. Furthermore, the water quality of the chamber began to deteriorate over the few weeks becoming a cloudy murky brown color.

The purpose of this lab is to isolate photoheterotrophic bacteria using an enrichment culture from a sample of marine sediment. The enrichment culture provides the photoheterotrophic bacteria with specific conditions to promote growth.

Water pollution is when, “one or more substances have built up in the water to such an extent that they cause problems for animals and people” (Woodford). Water pollution is also bad for humans and animal’s health. Sewage, chemicals, radioactive waste, oil pollution, and plastic, are some causes for water pollution (Explain That Stuff). When water from rain runs off roofs and roads into rivers it carries away trash, toxic chemicals, dirt, and harmful organisms (NRDC Water). Some solutions to these are to throw things into the correct bin, use water wisely, and not throw chemicals, oil, paints, and medicine down the sink, drain, or toilet. Also plant lots of trees and have cities develop a sewage treatment plant to minimize pollution (eSchool Today). It’s important to protect our

Water pollution impacts how humans and other living organisms live their life. Most common way humans are effected by water pollution is through diseases while drinking the water. Scientists have found over “five hundred different types of diseases” that can affect humans. (Book). These diseases get into the water streams by human and animal wastes. The diseases in the water can often lead to death for humans. Recent research has shown that that each year

pH of (7.68, 7.95) for the sample and its duplicate and they were within the normal ranges of the surface water pH (6.5-9.0). Conductivity of (178, 186) µS/cm for the sample and its duplicate and they were within the normal ranges of (150 to 500 µS/cm) that support diverse aquatic life. TDS of (106, 111) PPM for the sample and its duplicate and they are within the normal ranges ˂ 500 PPM, “in areas of especially hard water or high salinity, TDS values may be as high as 500 mg/L”. Temperature of (51.8, 55.5) F° for the sample and its duplicate and they were within the normal ranges ˂ 77 F°. Nitrate of (0.2, 0.8) mg/l for the sample and it duplicate and they were within normal ranges of the surface water Nitrate ˂ 1 mg/l.

 Water pollution is a problem that most everyone would agree does exist.  The toxic substances in the water can kill the plant life, animal life, and in some cases, the human life.  In Teluk Mengkuang, Sijangkang,  156 ponds filled with tiger prawns died

A reason that water pollution is a problem today is because many people don’t realize that they are hurting out water supplies when they really are. There are many pollutants that hurt our water supply such as farming. When farmers spray their fields with chemicals and apply fertilizers. Some of these chemicals reach the river, and animal urine and manure may be washed into the river. Another cause of water pollution is from accidents, such as tanker spills. Accidents with chemicals may cause river pollution as well. Mining can be another cause because the dusts and minerals get washed into the rivers. Seepage is another cause of water pollution. Because chemicals from waste dumps join the groundwater flow into the river. Urban Wastes is a major cause because the sewage comes from toilets, sinks, and industrial processes. This causes many human diseases such as diarrhea, dysentery, hepatitis, and cholera.

70 % of our Earth surface is covered by water and almost 60% of the human body contain water for nutrient transportation. The unique characteristic of water is water molecule is the only substance in this Earth that exist in all three physical states of matter which are solid, liquid and gas. All human beings need water to survive. The national development over the years cause the rate of water pollution increased. According to Gebre & Rooijen (2009) water pollution can be considered as a sign that derives from economic growth and is a common phenomenon in urbanized cities in developing countries. In general, there are three main issues that related to water pollution which are the causes, effects and the way to decrease this problem.

The next pollution will be water pollution. This pollution comes from factories, automobiles’’ exhausts and mines, which dump sewage directly into the water. Moreover, as an Agrarian country, the usage of pesticides for agriculture in India calls for water pollution too. Excessive usage of organic matter by farmers will also lead to the same consequent. As mentioned, deforestation will occur as population increase and the forests are stripped, soil erosion will happen and further cause sediments in water. Furthermore, people in India bathe in river for spiritual rejuvenate. However, as they warding off their sins in water, body wastes are excreted into the river as well, leading to river pollution. Religious

Rivers are the blessing on earth as they serve humans with ample fresh water supply. The purpose of the present study focuses on the combination of the GIS mapping, to indicate the status of pollution status in the sketch of River Mouri, downstream to the wastewater outfalls. The GIS mapping of the eleven wastewater study parameters reveals that the high concentrations of BOD5, COD, DO, Color, Turbidity, TDS and TSS exceeding the permissible limits is present throughout the study portion of the river. In addition, it highlighted the portions where only few parameters such as PH, Chloride, Nitrate and Sulphate are deteriorating the riverine ecosystem. The GIS application in pollutant load assessment of the study further indicates that although few pollutants, discharged into river are relatively low in concentrations at one wastewater outfall point as compared to other but may have high pollutant load that may leads to significantly higher ecological impacts. The possible application of this study is for the decision makers to introduce optimum treatment engineering controls at points of interests, prior to its disposal into River Mouri to prevent the ecological damages and protect human health.
