Results: Measurement of the heart rate and movement of Daphnia Pulex are the activites chosen as a quick, non- lethal assay of the impact of water pumped from the mine on stream organisms. Figure 1 shows a pattern of the response for heart rate of D. Pulex with three different baselines and 3 different concentrations from 250 parts per million, 125 parts per million, and 188 parts per million of Potassium Chlorine, KCl, concentration are used to checked for the lowest concentration that affects D. Pulex . The counts for the heart beat increases in average when the organisms are put in solution that contains KCl

Unformatted text preview: Figure 1: The effect of KCl on the heart rate activity The second activity chosen is the movement of the D. Pulex . Figure 2 illustrates another pattern of response towards the addition of KCl by couting the spins that the D. Pulex made. The number of movement made by D. Pulex increases in average after it is put in a solution containing KCl after 15 minutes. The solution that contains 370ppm of KCl has the highest increase in average of the movements.
