Textile affluent is one of the major sources of pollution in the Kabul River at the North-West Frontier Province of Pakistan. Effluent sample from individual processes of a textile mill at Now where were chemically evaluated for organic strength, total solids, trace toxic metals and other common pollutants. the results have shown different parameters to be in the range; temperature 32-130'C, pH 8.05-11.38, electrical conductivity 400-16160 µ mhos/cm. Total solid, which were measured g 105°C, 180°C and 550°C were respectively in the range of 460-18080 mg/l, 250-1613 mg/l and 240-14460 mg/l. Total dissolved solids at 105 C, 180°C and 550°C were found in the range of 360-1506 mg/l, .220-13430 mg/l and 210- 12740 mg\l respectively. Whereas, total suspended solids at these temperatures were found to be in the range of 100-3020 mg/l, 30-1670 mg/l and 3(k1030 mg/l respectively. Chemical oxygen demand was in the range of 1500-4160 mg O2/L Total hardness was 70-290 mg/1, calcium 0-60 mg/l, magnesium 50-230 mg/1, medium 40-3286 mg/l, potassium 12-236 mg/l, chloride 29-1918 mg/l, sulphate 529-2991 mg/l and sulphide 608-1832 mg/l. Trace toxic metals were found in the ranges; copper 0.04-0.17 mg/l, cadmium 0-0.16 mg/l, ciromium 0.5- 0.8 mg/l, nickel 04.04 mg\l, lead 0.07-0.14 and manganese 0.01-0.11 mg/l. It was concluded that the textile industry under study discharges various pollutants in concentratiom that are above the permissible limits laid down by the national and international standards. The textile effluents contain toxic metals, high oxygen demanding wastes and appreciable among of sulphide. this study also indicates the presence and the deleterious effects of industrial pollutants in general and sulphide in particular, as alarmingly high concentration of sulphide (608 times higher than the permissible limit) being discharged into Kabul River. this could logically be linked with the substantial decrease in fish crop specifically at and down-stream of the discharging point, and overall reduction in fish population in the Kabul River.
