RS-Freetext:SURVIVAL25°CAdult survival decreased with increasing copperconcentrations, however, this was only significantly reducedat the highest dose tested (3000 mg Cu/kg).The 28-day NOEC value was determined to be 1000 mg/kg ascalculated by both the added and total risk approach.20°CThe number of adults surviving were greater than the controlvalues in the 10 and 40 mg Cu/kg dose group although theincrease was not significant. The numbers of adultssurviving in the 200, 1000 and 3000 mg Cu/kg decreasedcompared to the controls, although this was not significant.The 28-day NOEC value was determined to be =>3000 mg/kg ascalculated by both the added and total risk approach.15°CAt 10, 40 and 200 mg Cu/kg there was an increase in thenumber of adults surviving (not significant) compared to thecontrols. The number of adults surviving decreased in thetwo highest dose groups and this was significant (P<0.01) at3000 mg Cu/kg. The 42-day NOEC value was determined to be 1000 mg/kg ascalculated by both the added and total risk approach.Juvenile Production25°CThe results presented, indicate that at 25°C, juvenileproduction of F. candida is too low for the effects ofcopper on this species to be determined. A NOEC valuecould, therefore, not be determined.20°CJuvenile production increased in the 10 and 40 mg Cu/kgcompared to the controls, however, this was not significant. Juvenile production decreased compared to the controls inthe 200 and 1000 mg Cu/kg dose groups, although this wasonly significant at 1000 mg Cu/kg (P<0.01). There were nojuveniles produced in the highest dose tested (3000 mgCu/kg).A 28-day NOEC value was determined to be 200 mg Cu/kg ascalculated by both the added and total risk approach.15°CThe number of juveniles produced decreased with increasingcopper, with the exception of 40 mg Cu/kg where morejuveniles were produced compared to the controls (notsignificant). Significant decreases in the numbers ofjuveniles were seen at 1000 mg Cu/kg (P<0.05) and 3000 mgCu/mg (P<0.01). There were no juveniles produced at thehighest dose.The 42-day NOEC value was determined to be 200 mg Cu/kg ascalculated by both the added and total risk approach.
The effect of copper on Folsomia candida was determined in artificial
OECD soil (70% sand, 20% clay, 10% organic matter, pH 6.0± 0.05) at
three different temperatures (15, 20 and 25°C). Mortality and
reproduction were assessed after 28 days for tests carried out at 20 and
25°C and 42 days at 15°C.
There was no reproduction at soil concentrations of 3000 mg Cu/kg at 20
and 15°C and at both these temperatures juvenile numbers were
significantly lower than those of the controls at 1000 mg Cu/kg. A
significant reduction in adult survival also occurred at the highest
concentrations at 15°.
