The contamination of soils with heavy metals due to rapid industrialization, modern farming
practices, and poor treatment of waste can damage the environment include agricultural …

This study was aimed to determine of lead (II) metal ion adsorption ability by using
adsorbents from the composite of andisol soil and fly ash. Andisol soil and fly ash were …

Four soils calcareous with different plant covers (tree cover, vegetable cover, field crop
cover, and natural grass cover) were selected from Erbil city of northern Iraq. Six samples …

Coal is an alternative source of energy besides petroleum and natural gas which are widely
