Salt Pollution :: essays research papers

table flavour PollutionAs awareness for contamination change magnitudes, new(prenominal) forms of pollution aredefined. Almost everyone knows more or less toxic waste and carbon dioxide pollution,but not many people piddle heard of salt pollution. flavour pollution has been onthe increase since the evolution of the automobile. With more pressure ongovernment agencies to keep the highway clear and safe, an increase in the useof salt has developed. It is important to figure why salt is used and howit work as well as the environmental cause to understand the salt pollutionproblem.Salt is a necessary and accepted part of the winter environment. Itprovides safety and mobility for motorists, commercial vehicles and emergencyvehicles. Salt is used as the hint deicer because it is the most unattachedand woo-effective deicer. Rock salt is preferred because it is cheap andeffective. It costs 20 dollars a ton where as an alternative wish well calciummagnesium cost around 700 doll ars a ton. Some 10 million tons of deicing salt isused each year in the U.S. and about 3 million in Canada.Salt is used to keep reversal and ice from bonding to the pavement and toallow snowplows to remove. When salt is applied to ice and snow it creates abrine that has a lower freezing temperature than the surrounding ice or snow.Salt is the ideal deicing material because it isthe least expensive deicer simplified to spreadeasy to depot and handlereadily availablenon-toxicharmless to skin and clothingSalt pollution is broken into two main groups. Water, which includesthe effects on set up water, come forth water and aquatic life and land.Most of the salt applied to the roadways eventually ends up in theground water. It is estimated that 30% to 50% of the salt used travels into theground water. Salt effect two areas of ground water, chloride concentration andsodium concentration. Chlorides may be present in the form of sodium chloridecrystals or as a ion in a solution. Normal co ncentrations in the water areaverage around 10 mg/litre. Concentrations found in ground water bordering majorhighways have been recorded as high as 250 mg/litre which is around thethreshold of taste.The main factor in with ground water pollution is the risk to human health.The raised level in sodium in water can cause high pitch pressure andhypertension. With people who already suffer from these problem it is necessaryto keep their salt intake relatively low, they should not drink water above 20mg/liter. Although this is recommended, a sight of private well water inToronto showed that half the wells exceeded this limit, twenty percent exceededSalt Pollution essays research papers Salt PollutionAs awareness for pollution increases, other forms of pollution aredefined.

Chlorides may be present in the form of sodium chloridecrystals or as a ion in a solution. Normal concentrations in the water areaverage around 10 mg/litre. Concentrations found in ground water near majorhighways have been recorded as high as 250 mg/litre which is around thethreshold of taste.The main factor with ground water pollution is the risk to human health.The raised level in sodium in water can cause high blood pressure andhypertension.
