(In 2017, Bangladesh became the first government to
ban ketoprofen in addition to diclofenac, though only inside the safe zones.)
A block down the potholed street, Nurul Alam, a veterinary technician with the government's Department of Livestock who advises locals on animal care, seems unaware that
ketoprofen is
banned in the zone.
The first method Alizadeh Fard and Barkdoll tested was to use polymer - coated magnetic nanoparticles to adsorb Tonalide (used to mask odors and often found in detergents), Bisphenol - A (better known as BPA, used to make plastics clear and tough), Triclosan (an anti-bacterial and anti-fungal agent used in cleaning products that is now
banned), Metolachlor (an herbicide),
Ketoprofen (an anti-inflammatory) and Estriol (an estrogen supplement).
