These chemicals are often used in various industries and it is a primary concern in industrial settings where a lot of workers are exposed to high concentration for a long period of time. Aromatic solvents tend to work with a mechanism which implicates both the nervous system and cochlea. The hearing problems caused by aromatic solvents are irreversible. Nitriles are such chemicals which are generally associated with permanent hearing loss and cause severe damage to the cochlea. These chemicals can also affect the vestibular organ in the ear and cause impairment in coordination and in balance. Asphyxiants also affect the cochlea but in a different manner. When hearing impairment is caused by low levels of asphyxiants, it is rever...
