This study is to prepare a cellulose paper was impregnated with silver nanoparticles (AgNPs) for the purpose of water purification (Disinfection (removal of several types of bacteria) and filtration). Sliver nanoparticles used in this work exhibit a broad size distribution with highly reactive facets. AgNPs paper provided rapid and effective bactericidal activity as the bacterially contamination.

We investigated the effect of long exposure to sunlight (as is practised by retailers & peddlers in Bauchi state, Nigeria) of commercial plastic bottled drinking water. Level of physical/chemical parameters were measured for five (5) brands & found that levels of pH, Antimony, Nitrates & Bisphenol A changed significantly as the time of exposure increased. Thus, highlighting the importance of proper monitoring of storage & retailing of plastic bottle products to safeguard health of consumers.
