Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas
