Heavy metal accumulation in freshwater ecosystem has become one of the major aquatic environmental concerns for freshwater flora and fauna due to their higher stability and bioaccumulation as well as bio-magnification properties. Furthermore, passing through the food web, these heavy metals affect human populations ultimately. This study assessed the heavy metal accumulation in Cirrhinus mrigala in spring, autumn, and winter at different locations (I, II, and III) of Panjnad headwork. Furthermore, the human health risk assessment for the consumption of C. mrigala from the sampling locations was also carried out. Fish were collected from upper (I), middle (II), and lower (III) stream of Panjnad on a monthly basis. The current study evaluated the accumulation of Aluminum (Al), Arsenic (As), Barium (Ba), and Lead (Pb) in various fish organs (liver, kidney, gills, fins, skin, muscles and bones) and assessed their potential hazard to human health through health risk assessment indicators. The results demonstrated a significant difference (p < 0.05) in heavy metal accumulation in different fish organs, seasons, and locations. The accumulation of Al, As, Ba, and Pb were considerably higher in liver and kidney as compared to the other body organs and followed a trend of liver > kidney > gills > fins > skin > bones > muscle and the overall mean concentrations of metals in different body tissues of C. mrigala were in the order of Al > As > Ba > Pb. The results also concluded that C. mrigala caught from the Panjnad headwork is not safe for human consumption due to higher values of TTHQIng (3.76), THQIng for Ba (3.27) and CRIng for As (6.4742).

Levels of nickel and chromium in leaves of 14 plant species grown in industrial sites of Gaziantep and surrounding were examined for biomonitoring of atmospheric pollution using flame atomic absorption spectrophotometry (FAAS). The plant leaf samples were collected from different locations with different degrees of metal pollution. The metal levels in the plants were in the ranges of (with mean values) 0.4-28.0 (3.1) mg kg(-1) for Ni and 0.1-6.6 (1.5) mg kg(-1) for Cr. On the other hand, the Ni and Cr levels in the plant leaf samples collected from control) areas were in the ranges of 0.4-2.1 (1.1) and 0.1-1.4 (0.58) mg kg(-1), respectively. It was concluded that Pinus nigra L., Acacia robinia L., Platanus orientalis L., Nerium oleander L., Pyracantha coccinea M.Roem. and Populus nigra L. for Ni, Pinus nigra L., Acacia robinia L., Olea europaea L. and Nerium oleander L. for Cr could be biomonitors. Therefore, it was demonstrated that the plant leaves could be used for heavy metal air pollution monitoring in urban and industrial regions.
