Effects of Organic Chemicals in Sludge Applied to Soil

Degradation and Toxicity to Organisms Living in Soil

Abstract
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.
