1) CARBON MONOXIDE * It is a colourless, tasteless & odourless gas. * It is produced as a result of incomplete combustion of carbon * It is highly poisonous to humans as it blocks the delivery of oxygen to the organs & tissues * It binds haemoglobin in blood and forms CARBOXYHAEMOGLOBIN * When the percentage of Carboxyhaemoglobin increases in blood, the oxygen carrying capacity of blood is greatly reduced * This is called CARBON with MONOXIDE poisoning * In such situations, a person may suffer from HEADACHES,BLURRED VISION, DIZZINESS,NAUSEA, CONFUSION, NERVOUSNESS, SHORT OF BREATH, LOSS OF CONSCIOUSNESS & CHEST PAIN DUE TO HEART ATTACK * If this gas is inhaled in high amount, this may also lead to death * This is one of the reason people are advised not to smoke 2) OXIDES OF SULPHUR * Sulphur dioxide is poisonous for both plants & animals * Even a very low concentration of this gas may cause respiratory diseases like ASTHMA, BRONCHITIS, EMPHYSE...
