Kassandra Coan Why put lime in a pond? Honors Activity 5.4 Lime is a commercial name for calcium oxide (CaO). When carbon dioxide (Co2) is removed from limestone‚ coral‚ seashells‚ or chalk they become lime. This product is easily accessible‚ because an abundance of limestone in found in the crust of the earth‚ and the Co2 is removed simply by heating the limestone. See formula below: 500-600

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction

The problem is that there is no way to return the waterborne phosphorus to the soil so the bodies of water end up being over fertilized. With the over fertilizing of the ocean is leading toward a severe water pollution problem which is known as eutrophication. (Boorse‚ 2011) The Nitrogen cycle has similarities to the carbon cycle and the phosphorus cycle. Both carbon and nitrogen cycles both have gas phases‚ and Phosphorus and Nitrogen act with limited factors. Nitrogen is a primary nutrient critical

powders and detergents contain phosphates which are used to soften the water. These and other chemicals contained in washing powders will increase the acidity of the water and affect the health of all forms of life in the water. The next factor is eutrophication. Untreated domestic sewage and run off from agricultural fields lead to excessive amount of nutrients such as phosphorus and nitrogen flowing into the natural water. Accumulation of the nutrients‚ particularly phosphorus in the water leads to

medals from industries dissolve in nearby lakes and rivers which is toxic to marine life. Organic matter and nutrients thrown in the water increase the amount of algae which reduces the amount of oxygen from the water column which is called eutrophication and cause the suffocation of fish and other aquatic organisms. The amount of waste particles suspended in water reduce the amount of sunlight received into the water which disrupts the growth of photosynthetic plants and microorganisms which
