MSMA (monosodium methanearsonate) is an arsenic-based grass killer. It kills grassy weeds such as crabgrass and goosegrass without harming most turfgrasses. It contains organic arsenic that, according to the University of Tennessee Extension, is less harmful than aspirin.
There are several styles of hearing aids available, from the smallest - Invisible in the Canal (IIC) to the largest and strongest - Power Behind the Ear (BTE), and the very popular Receiver in the Canal (RIC) - made to fit most hearing losses while remaining nearly unseen.
This type of hearing aid can be considered when a child has either a conductive, mixed or unilateral hearing loss and is specifically suitable for children who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids.his type of hearing aid can be considered when a child has either a conductive, mixed or unilateral hearing loss and is specifically suitable for children who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids.
