The HN03 - I-1202 digestion.... s ystem was used to digest the fish sample far trace m etals det ermination. Tire HN03 - H202 digestion method gave good recoveries which vCiries within 80-95 % for Cd, 85-97% for Co, 81-99% for Cu, 79-97% for Mn, 81-93% for Ni, 87- 98% for Pb Clnd 77 - 98% for Zn in a fish smn...
