Comments on "Enhanced removal of Cr(VӀ) from aqueous solution by supported ZnO nanoparticles on biochar derived from waste water hyacinth".

abstract：:Eleven years (2005-2015) of data from long-term monitoring at a Japanese remote background site in Wajima, were analyzed to investigate temporal trends and sources. Water-soluble inorganic ions (WSIIs) were analyzed for aerosol chemical composition. The total WSIIs concentration was 7.93 ± 3.93 μg/m3, accounting for 4...
