This study analysed heavy metals from little egret (Egretta garzetta). Egret's Eggs, egg shells, food (fish and insects), blood, meat samples (thigh, liver, and chest), water, soil and sediments samples were collected from the two selected sites of the study area. Samples were analysed on flame atomic absorption spectrometer after acid digestion. Detected metals were found almost inline of concentrations when compared with the both sites. Among detected metals Mn was found higher in concentration (µg/g) i.e. 18.509 followed by Zn i.e. 9.383, Ni, Cu, Pb and Cd. Sediment exhibited higher levels (µg/g) of metals (25.061) followed by the meat (19.044) egrets food (18.825), excreta (16.26), blood serums (4.577), eggs (3.626) and water samples (2.432).The level of metals in sediments of the study are showed environmental concerns. Health risks were also investigated that were compared to guidelines of WHO and FAO threshold limits. It was found a marginal health risk to life through detected metals. This study revealed that little egret are good bio-indicator for the screening and investigation of contaminates presence in the environment.
