Temperature Temperature affects various processes in the water quality (ANZECC 1992). The rate of chemical reactions, for example, is activated when high water temperature occurs which causes evaporation of certain substances that may be present in the water. Also, as water temperature increases, the solubility rate of gases in water, such as oxygen (O2), decreases and respiration rates of aquatic organisms increases which results to greater oxygen consumption (Chapman and Kimstach 1992). A change in water temperature also causes greater destruction of aquatic life and problem of unwanted growth of water plants and wastewater fungus (Metcalf and Eddy 1991).
The normal temperature of surface waters which generally ranges from 0oC to 30oC can be influenced by factors such as geographical position, seasonality, diurnal period, circulation of air, and quantity of cloud cover, depth of water and flow rate. Also, abnormally high temperatures can arise from discharges of industrial effluent and sewage treatment plants (Chapman and Kimstach 1992). pH

The pH of natural water stays in between 6.0 and 8.5 but could be affected by chemicals entering the waterways (Chapman and Kimstach 1992). Assessing water quality can be best done with the use of this parameter as it affects many biological and chemical processes within a water body (Chapman and Kimstach 1992, p.62). Extreme pH affects the adaptation of many aquatic macroinvertebrates by disrupting their natural physical and environmental processes. Moreover, the availability of nutrients such as calcium and magnesium may be affected when pH becomes too low from river’s normal
Firstly, when testing temperatures at 30°C and 40°C, the water was. sometimes heated more than needed, so I had to wait until it cooled. down to the required temperature. To avoid this happening, a. thermostatic water bath could have been used, because I could set it. to the required temperature.
As certain types of pollution damages our atmosphere, our natural protection from the sun weakens and as a result the Earth gets warmer with time, impacting the temperature of our seas. The unfortunate results of global warming and the co...
The ineptitude of the monogastric animals to fully hydrolyze the phytic acid resulted in several problems. For instances, supplementation of inorganic phosphate, which is expensive, is needed to compensate with the inability of the monogastric animals to utilize phytic acid. The supplementation of inorganic phosphate in the animal feeds is crucial to meet the animals’ dietary requirements. Furthermore, the unutilized phytate-phosphorus causes the concentration of phosphorus in the animals’ excreta increases and this will indirectly contributes to serious phosphorus pollution complication (Pen et al., 1993; Volfova et al., 1994). Cyanobacterial blooms, hypoxia and death of marine animals have been reported to occur as a consequence of the eutrophication of the rivers by this excessive phosphorus (Mallin, 2000; Naqvi et al., 2000). In fact, phytic acid has been well-known for ...
Methodology: The experimenter used two ten gallon tanks. One tank will be used for the controlled group and the other tank will be used for the experimental group. Each tank will have two pounds of sand spread among the bottom of the tank along with rocks and artificial habitats to add nitrogen to the tanks. To add optimal living conditions for the oceanic life water filtration systems, temperature regulator, circulation systems, and a light to mimic the sun’s rays were added to each tank. At all times both tanks had a temperature of 75 degrees F. This experiment was done over a three month period. The first month was to allow the nitrogen cycle to occur. This allows the fish to be exposed to the water without having stress reactions due to unhealthy living conditions due to the nitrogen. Once the first month was complete six fish was added to both tanks. Two tangs, two damsels, and two clownfish. At first both tanks had a pH level of 8.2, ideal living conditions. After one week the experimental group was exposed to a pH level of 8.6. After two weeks it was raised to 9. Two weeks later it was raised to 9.3. The final raise was done two weeks after making the pH level 9.5. The final week of the experiment the pH lev...
The researcher conducting this experiment is trying to find out which salt- Epsom, table salt, and sea salt- will increase the boiling point of water the most. Sodium chloride is believed to increase the boiling point of water because when salt is suspended into the water, the sodium and chlorine ions leave the “salt crystals” and mix with the water molecules. (“Why does salt… raise boiling point of water?”, 2009).
About 80% of the State’s surveyed freshwater rivers and streams have good water quality that fully supports aquatic life uses, 17% have fair water quality that partially supports aquatic life uses, and 3% have poor water quality that does not support aquatic life uses. Ten percent of the surveyed rivers do not fully support swimming. The major sources of impairment are agriculture (responsible for 53% of the impaired river miles), urban runoff (responsible for 16%), and construction (responsible for 13%). These sources generate siltation, bacteria, and organic wastes that deplete disssolved opxygen.
The hypothesis for this experiment was, If three different types of waters (saltwater, fresh water, tap water) are tested, then the liquids won’t evaporate at the same rate and tap water will evaporate at the fastest rate because it won’t have any non-volatile substances to hold it back from evaporating.

Water pollution is also a major thing in the world because almost 60% of it is fishes. It occurs due to several factors; the industrial waste dumped into the rivers and other water body’s cause am imbalance in the water leading to its severe contamination and deaths. And the infamous Global warming is the emission of greenhouse gases particularly CO2 is leading to global warming.
