The skin of fresh water edible fish Notopterus notopterus was analyzed for the determination of essential and nonessential metals under fluoride stress. Levels of selected metals like Lead (Pb), Mercury (Hg), Magnesium (Mg), Iron (Fe), Zinc (Zn), Sodium (Na), Calcium (Ca), Potassium (K), Fluoride (F), and Chloride (Cl) at different time intervals with fluoride at 1.5 g and 3 g in the skin of Notopterus  notopterus from Keenjhar lake, Sindh, Pakistan, were determined using Perkin – Elmer Atomic Absorption Spectrophotometer . It was found that all metal concentration was increased as compare to control group. The trend of accumulation of selected metals in the skin at 1.5 g of fluoride for 24 h Na > Mg; At 48 h Na, Ca, Mg > Pb, Fe > K > Cl; At 72 h Mg > F > Ca > Cl > Pb > K. The trend of accumulation of selected metals in the skin at 3 g of fluoride at 24 h Pb >Mg; At 48 h Na > Mg > Fe > Cl, Ca > Pb > & Hg, F; At 72 h Mg > Cl > Ca > Pb, Na > Hg & K.

Keywords: Generalized additive model, relative humidity, windspeed, mortality, sensitivity analysis, time series analysis.
