Iron is the tenth most abundant element in the universe. But from micro-organisms to human iron is most essential to survive. Every year around 500 million tons iron is being produced. It adds around 300 million tons more when we count the recycled iron. China, Australia, Ukraine, Russia and Brazil are the main mining areas for iron. Every year more than 100 billion tons economically reserves iron ores exceed 100 billion tons.
Though iron is one of the top abundant metals but the effect of iron is undeniable. Potatoes, vegetables, whole meal products and even meat contain iron. Human body can easily absorb iron from meal products rather than from plant products. To run human body actively, we need to transport oxygen through our body. Hemoglobin, the red agent of our blood does this transportation. Iron is the most essential part of hemoglobin.
But iron is the reason for retinitis, conjunctivitis and choroditis. Siderosis, a benign pneumoconiosis develops for inhalation in excessive iron oxide fumes or dusts. Also, excessive inhalation is iron oxide fumes increases the chance of lung cancer. Anaemia, a more common problem for humans is caused by iron. Any adult male needs 7 mg and female needs 11 mg daily. A proper diet usually serves the amount but if it isn’t sufficient then iron pill must be taken after consulting with doctors.
Iron isn’t only essential for human body. Excessive iron attachment caused serious hazards. Also, iron does a negative impact on environment we live. Iron (III)-O-arsenite caused great problem on environment. Iron (III)-O- Pentahydrate is also hazardous. When iron containing chemicals enter into the environment they persists and most of the time affects the eco-balance and caused various health problems. Factories and industries must be strongly advised to not let the iron containing chemicals enter into the environment.
