| Abstract |
|
eng: Phthalates, NP's, and NPE's degraded
slowly, if at all, during 28 days in soil-sludge mixtures, while LAS degraded fairly
rapidly. Biodegradation of sludge for 14 days reduced the nitrification process, but the
sludge was still toxic to the reproduction of collembola. Sludge-bound NP and LAS showed
no effect on nitrification or survival of adult collembola, but there was a marked effect
on collembolan reproduction. PEC/PNEC > 1 for both NP and LAS. For LAS the ratio
decreased to below 1 after 141 and 174 days respectively for two soils. |
| Resumé |
|
dan: Phthalater, NP'er, og NPE'er blev kun
langsomt nedbrudt eller slet ikke i løbet af 28 dage i slam/jord blandinger. LAS blev
relativt hurtigt nedbrudt. Bionedbrydning af slam i 14 dage reducerede giftigheden over
for nitrifikationsprocessen, men det havde stadig effekt på springhalereproduktionen. Der
sås ingen effekt af slambundet NP og LAS på nitrifikation eller overlevelse af voksne
dyr, men der var en klar effekt på forplantningen. PEC/PNEC > 1 for både NP og LAS.
For LAS faldt værdien til under 1 i løbet af henholdsvis 141 og 174 dage for 2 jorder. |
