For cadmium, there is a decline in

For cadmium, there is a decline in LC50 value from 24h to 96h as 131.78, 84.58, 51.39 and 58.99 ppm. Decrease in LC50 value is noted with the increase in exposure period. The difference between the LC50 values of 72 and 96h is low and the difference between 24h and 48h is high. For cadmium, there is a decline in LC50 value from 24h to 96h as 151.91, 121.36, 106.88 and 96.57 ppm (Table 2). The difference between the LC50 values of 72 and 96h is high whereas it is low in the case of 48 and 72h. Among the two metals tested, nickel is more toxic to O.mossambicus than cadmium.

Vir kadmium, is daar 'n afname in die LC50 waarde van 24h tot 96h as 131,78, 84,58, 51,39 en 58,99 ppm. Afname in LC50 waarde is bekend met die toename in blootstelling tydperk. Die verskil tussen die LC50 waardes van 72 en 96h is laag en die verskil tussen 24h en 48h hoog. Vir kadmium, is daar 'n afname in die LC50 waarde van 24h tot 96h as 151,91, 121,36, 106,88 en 96,57 ppm (tabel 2). Die verskil tussen die LC50 waardes van 72 en 96h hoog, terwyl dit laag in die geval van 48 en 72h. Onder die twee metale getoets, nikkel is meer giftig vir O.mossambicus as kadmium.
