Determination of heavy metals

The present study was conducted on Head Punjnad (HP) and Head Taunsa (HT) to evaluate the contamination of Pb, Cr, As, Hg, and Cd in water, soil, sediment, fish as a whole and fish organs. Fish, water, soil and sediment samples were collected from different sites of HT and HP on a monthly basis for...

Description
Summary:The present study was conducted on Head Punjnad (HP) and Head Taunsa (HT) to evaluate the contamination of Pb, Cr, As, Hg, and Cd in water, soil, sediment, fish as a whole and fish organs. Fish, water, soil and sediment samples were collected from different sites of HT and HP on a monthly basis for 8 months. Heavy metals in water, soil, and sediment were determined by a polarized Zeeman atomic absorption spectrophotometer and in fish and fish organs by an atomic absorption spectrophotometer. Contamination of Cd, Hg, and As was significantly (P0.05) difference at HP and HT. Pb was significantly (PS. sarwari >C. idella >C. catla >N. notopterus >E. vacha >L. rohita >C. carpio, respectively. Hg as O. niloticus >S. sarwari >R. rita >C. marulius >C. catla >N. notopterus >E. vacha >L. rohita >C. carpio >C. idella, respectively. As as O. niloticus >R. rita >S. sarwari >C. marulius >C. catla >C. carpio >N. notopterus >C. idella >E. vacha >L. rohita, respectively. Cr accumulation recorded as L. rohita >C. idella >O. niloticus >C. marulius >E. vacha >R. rita >C. catla >C. carpio >S. sarwari >N. notopterus, respectively. Pb accumulation in different fish species was recorded as C. idella >C. carpio >N. notopterus >L. rohita >O. niloticus >C. marulius >R. rita >S. sarwari >E. vacha >C. catla, respectively. Cd accumulation in different organs was recorded as kidney >liver >gills >muscle >skin >scale. Hg accumulation in different organs was recorded as kidney >gills >liver >skin >muscle >scale. As accumulation in different organs was recorded as kidney >liver >gills >muscle >skin >scale. Cr accumulation in different organs was recorded as gills > liver >skin >muscle >kidney >scale. Pb accumulation in different organs was recorded as gills> kidney> skin> liver> muscle> scale.
