Title: Reduction of fluoranthene of copper and lead accumulation in Triticum aestivum L

Abstract

Fluoranthene is one of the most important representatives of the polycyclic aromatic hydrocarbons. Coaltar production alone yields about 30000 t of fluoranthene per year. In spite of its abundance, however, very little is known about its effects on the environment. Groenewegen and Stolp investigated the half-life of this substance in soil and found values between 44 and 182 days, depending on the soil matrix. PAHs may migrate into soil organic matter, representing less accessible sites within the soil matrix. Such sorbed PAHs are suggested to be non-bioavailable and thus non-biodegradable. Fluoranthene has long been classified as non-carcinogenic and largely non-hazardous. The oral toxicity rating is indeed low, being only 2000 mg [center dot] kg[sup [minus]1] for rats and mice (LD[sub 50]), but there are also reports of mutagenic and toxic effects of fluoranthene on animals and plants. Fluoranthene has been reported to be synthesized by spermatophytes. However, accumulation of fluoranthene and other PAHs in plants is generally attributed to contamination by airborne particulate matter. Lettuce, soya, rye and tobacco plants grown in air-filtered chambers failed to synthesize PAHs, but accumulation of such substances was observed in a normal greenhouse. Transfer of fluoranthene from polluted soil via roots to shoots ismore » probably limited due to the high n-octanol/water partition coefficient log P[sub OW] of fluoranthene: 5.33. However, there seems to be a stimulation of PAH uptake by mosses and spermatophytes in heavy metal-stressed soils. The aim of the present study was to determine toxic effects of fluoranthene on wheat and whether there were any interactions between toxicity and uptake of fluoranthene, lead and copper in hydroponic culture systems. 21 refs., 4 tabs.« less
