Water pollution is caused by pollutants which are discharged either directly or indirectly into the water bodies without proper treatment for the removal of the harmful components. Water pollution affects plants and other living organisms that are present in water bodies; the effect of water pollution is not only damaging individual species and populations, but in fact the natural biological communities as well. Surface waters are referred to as natural water resources or the Earth. Surface water pollution is divided into two major categories: point sources and non-point sources. Point source pollution is where pollution is caused from a single source and can also be identified. Non-point source pollution is where pollution is not caused by just one source in fact; it is the diffused contamination that occurs from different sources rather than just one. (Water Pollution Guide)
There are many causes for water pollution. The first major water pollution pollutant is sewage and wastewater. Activities such as domestic work, industrial and agricultural practices produce wastewater which then pours in the clean water stream and contaminates it. Sewages water contains pollutants such as faeces, urine and laundry wastes. The world population has reached 7 billion, therefore, sewage treatment is vital and population is like to grow hence we need to take of this cause or there will be ever-increasing water pollution. Sewage is a major problem especially in the developing countries where they do not have access to good sanitary conditions and safe water. Untreated sewage causes diseases such as diarrhea. Sewage is mainly biodegradable but sometimes is contains chemicals and pharmaceutical substances, sewage also contains viruses and bacteria thus causing health problems. (Fuller) Another major cause of water pollution is marine dumping. Marine dumping is when humans dump garbage into the sea or ocean. This then causes the water to directly become polluted. This is a major problem throughout the world and the developing countries in particular. Since developing countries do not have a proper waste disposal system then the people dump their waste into the sea. For instance Karachi, a city in Pakistan, used to attract high numbers of tourist because of their geographical location that has more than 6 beaches. However, due to marine dumping tourism in that region has dropped tremendously in that region. Different items take different times to degrade in water, some take a shorter time for instance cardboard – two days, and some take a very long time for instance plastic packaging material – about 400 years. (Fuller) One more major cause of water pollution is industrial water and waste. Industrial waste is a huge cause of water pollution because it produces pollutants that are very harmful and dangerous to the people and the environment. Many industrial facilities use fresh water as a source to wash and carry their waste out of their vicinity into different water bodies. There are ample amounts of industrial pollutants. First is asbestos. Asbestos is carcinogenic and is a serious health hazard. It can be inhaled and can cause deadly diseases such as lung, ...Download file to see next pagesRead More

...high cost and utility makes it important to manage it properly. Also management from the point of view of keeping radioactive materials secure is also important since in the wrong hands, radioactive materials can be used to spread terrorism in the world. (IAEA, 1995) Impacts of Improper Waste Management As mentioned in the last section, there exists a lot of threats to the integrity and solidarity of a nation without a proper waste management program. (AUA, 2007) Environmental and Social Impacts Radioactive waste is hazardous for the natural environment in high quantities. Once the radioactivity escapes into the environment, humans and...

Radioactive Waste Disposal Essay
...) Features of a nuclear waste repository Radioactive wastes are fabricated by three groups of activities: the production of nuclear electricity; the production of nuclear weapons; and, in much less significant quantities, in nuclear research, medical practice and certain industrial activities. Radioactive waste restrains an extensive range of material with widely varying characteristics. Some has relatively slight radioactivity and is safe to handle, while other types are intensely hot in both temperature and radioactivity. Some decays to safe levels of radioactivity in a matter of days or weeks, while...

Comparison in the corresponding rates of decay of uranium ore and other HLW from the reprocessing of spent fuel. Source:World Nuclear Association 2001, Radioactive Wastes. The classification of radioactive wastes and their disposal depends on how long it remains highly radioactive, the concentration of the radioactive material in the waste and whether the waste is heat generating. The persistence of the radioactivity determines how long the waste requires management. The concentration and heat generation dictate...

.... and Pauwels 336) It is also applied in the imaging of parathyroid glands in determination of the presence of an overactive gland, a situation known as hyperparathyroidism. Iodine is also applicable in a thyroid uptake test imaging thyroid glands in order to find out hyperthyroidism causes. Its other isotope is applied in treating Graves’ disease through destruction of thyroid tissues. In general, radioactive elements treat and diagnose medical diseases. Technetium 99 isotope This Isotope is of technetium that decays with 211,000 years half life compared to a steady ruthenium 99, and hence emits beta rays rather than gamma rays (D.L and Heirsman, 164) Decay equation The isotope’s role Based on the...

...Chemistry 14 November Materials in Green Cement The largely used construction material globally is Portland cement with an annual production of about 12 billion tones. However, its production utilizes vast amounts of raw materials such as limestone and sand, liberating a ton of carbon dioxide gas per ton of cement produced (Shah & Wang 15). The current focus on sustainable development in concrete technology aims at producing more environmentally friendly cement, which spawns less carbon dioxide and expends less energy. Such environmentally favorable cement is what is referred to as “green cement.” This paper focuses on the advancement of “non-clinker green cement” through the utilization...

...MATERIALS FOR CONSTRUCTION Registration Number: In this case, we are going to compare two structures. We have structure A and structure B. structure A is a 500 slab. This slab is 30 cm thick, so the total volume of the slab is 150. This structure has a tidal zone of San Diego. This is the reason why the structure has constructed using quite a strong mixture. On the other hand we have structure B which is a 800 circular column with a thickness of 50 cm. the total volume for this structure is 400. The analysis period for this structure is similar to that of the above structure. This structure is also exposed to the tidal zones of Miami. The main differences occur in the mixtures that were made and used in...

Physics Project (( Radioactive decay ))
...Physics lab report: Radioactive decay Physics lab report: Radioactive decay In this experiment, we investigated the radioactive decay process by using pennies to simulate the nuclei decay process. Throwing of pennies is a probability process and we were to find out if it is a good model to represent the nuclei decay. We used a box with a lid and a number of pennies to carry out the experiment. The penny was taken to have decayed when its head came up. We investigated the half-life of the pennies and full decay time by looking at the probability about both small numbers and large numbers. We also investigated how many times it will take all the pennies to decay to zero. We used excel...

Journal One: Identifying Conflicts From Other Sources
...Journal Entry Conflict is an integral part of literature and this literary device involves a struggle between a protagonist and an antagonist. Conflicts may be external or internal in nature. Internal conflicts are inner feelings, emotions or psychological tussles that prevail within a character’s heart and mind. The character experiences two different feelings or is forced to decide between two entirely different pathways; a situation that creates disagreement within a person’s self. External conflicts on the other hand are the results of actions or words of other characters in the story. Internal conflict is often portrayed as an extremely complicated issue. A struggle between the ethical values and...
