Wenjie, O.; Ahmed, Waqas; Xiuxian, Fu; Lu, Wang; Jiannan, Li; Jie, Yang; Asghar, Rana Muhammad Ammar; Mahmood, Mohsin; Alatalo, Juha M.; Imtiaz, Muhammad; Li, Weidong; Mehmood, Sajid... more authors ... less authors (2022 , Article)Aqueous solutions containing toxic elements (TEs) (such as hexavalent chromium (Cr (VI)) can be toxic to humans even at trace levels. Thus, removing TEs from the aqueous environment is essential for the protection of ... -
Aquaculture sediments amended with biochar improved soil health and plant growth in a degraded soil
Sajid, Mehmood; Ahmed, Waqas; Mahmood, Mohsin; Rizwan, Muhammad Shahid; Asghar, Rana Muhammad Ammar; Alatalo, Juha M.; Imtiaz, Muhammad; Akmal, Muhammad; Abdelrahman, Hamada; Ma, Jifu; Ali, Esmat F.; Li, Weidong; Lee, Sang Soo; Shaheen, Sabry M.... more authors ... less authors ( Elsevier , 2023 , Article)Sustainable and safe management of aquaculture sediments is of great concern. Biochar (BC) and fishpond sediments (FPS) are rich in organic carbon and nutrients and thus can be used as soil amendments; however, it is not ... -
