“…Coal ash waste could be potentially hazardous to the environment since it contains heavy metals such as Zn, Pb, Mn, Cu, Cr, Cd, and Se, according to previous studies. Lead (Pb), arsenic (As), nickel (Ni), selenium (Se), copper (Cu), zinc (Zn), chromium (Cr), cadmium (Cd), and manganese (Mn) are just some of the metalloids and heavy metals that can be established in bottom ash and y ash (Dinçer et al, 2007;Pandey et al, 2011;Su and Wang, 2011;Jayaranjan and Annachhatre, 2013). Metals like Cd, As, and Pb can be harmful if they leach into the water, and this is especially true if the water is acidic.…”
