1. Temperature : A temperature is an objective measurement of hot or cold. It is measured by thermometer (Paul S. Welch,1938). Its most common unit is celcius. It is an important physical property of water because temperature controls the rate of most of the chemical reaction. As temperature affects the growth, reproduction and immunity of living organisms, therefore, drastic temperature changes can be fatal to living organisms.
2. pH : pH is a numeric scale used to specify the acidity or basicity of aqueous solution. pH measurements run on a scale from 0 to 14, with 7.0 considered as neutral (Victor and Robinson,1939). Solutions with a pH below 7.0 are considered acids. Solutions with a pH above 7.0, up to 14.0 are considered as bases. It …show more content…
Hardness : Hardness of water is a measure of the total concentration of the total concentration of the calcium and magnesium ions expressed as calcium caebonates. Water that has high mineral content is known as hard water (Patil et al.,2012). Hard water contains bicarbonates, chlorides and sulphates of calcium and magnesium.
6. Alkalinity : Alkalinity is a measure of the ability of water to neutralize the acids and its ability to maintain relatively constant Ph(buffer). Alkalinity influence the contamination of many substances present in the water. It can be determined by various menthods ,one of which include the use of simple dil.HCL titrations in the presence of phenolphthalein and methylorange indicators. Presence of hydroxyl and carbonate ions in the boiled water results in …show more content…
Chlorine : Chlorine is a toxicant which is identified as leading cause of bladder cancer and also associates with rectal and blood cancer. It has been reported that asthma can be triggered by chlorinated water if we drink it (Watson and Kibler, 1993). Chlorine is used as disinfectant as it kills the microorganisms like certain bacteria, but the trouble is that it does not know when to stop killing which will lead to toxic effects for the body. It has also been shown that exposure to chlorine and hypochlorite will lead to dermatitis (Eun et al., 1984). Various researchers have been shown that there is effect of drinking water chlorine on lipid metabolism and thyroid functioning in white carneau pigeon (Revis et al., 1986). When we treat the water with chlorine to remove the bacterial contamination then there are chances that Chlorine reacts with naturally occurring organic material in raw water supplies to produce the chlorinated by-products (CDBPs). The most commons are trihalomeathanes (THMs), haloacetic acids and haloacetonitriles. THMs are the most abundant CDBPs. These CDBPs are carcinogenic and cause pancreatic cancer (Minh et al., 2005). Specifically, trihalomethanes (THMs) found to be associated in causing liver and kidney cancer in animals (Dunnick and Melnick, 1993). There is evidence that after CDBPs exposure chances of having bladder cancer are increased (Morris et al.,
