“…The HMW-PAHs with low solubility are generally less mobile and have low vapor pressure and high octanol-water (K OW ) and octanol-air (K OA ) partitioning coefficients. According to Sverdrup et al [24], PAHs (such as Ph, Pyr, Flu, and Fl) with log K OW -values ranging between 3.5 and 5.2 reduced the early stage growth of terrestrial plants. In addition, LMW-PAHs are more mobile in the soil and more likely to adsorb onto the root surface and easily transfer further into the root interior [25].…”

Accumulation of polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) by crop plants from contaminated soils may pose health risks. A greenhouse pot experiment using lettuce (Lactuca satuva L.) as a representative vegetable was conducted to assess the concentrations of PAHs and HMs in vegetables grown in wastewater-contaminated soils. The concentrations of total PAHs were ranged from 1.5 to 3.4 mg kg −1 in the contaminated soils, while 1.2 mg kg −1 in the reference soil. Linear regression analyses showed that the relationships between soil and shoot PAH concentrations were stronger for LMW-PAHs (R 2 between 0.51 and 0.92) than for HMW-PAHs (R 2 0.02 and 0.60), suggesting that translocation for LMW-PAHs is faster than HMW-PAHs. Furthermore, the data imply that root uptake was the main pathway for HMW-PAHs accumulation. The plant shoots were also highly contaminated with HMs, particularly Cd (0.4-0.9 mg kg −1 ), Cr (3.4-4.1 mg kg −1 ), Ni (11.7-15.1 mg kg −1 ) and Pb (2.3-5.3 mg kg −1 ), and exceed the guidance limits set by State Environmental Protection Administration (SEPA), China and the World Health Organization (WHO). This study highlights the potential health risks associated with cultivation and consumption of leafy vegetables on wastewater-contaminated soils.

“…However, parameters such as germination (Keddy et al 1995;Sverdrup et al 2003) and growth (Robidoux et al 2004) have been under debate on whether being really sensitive endpoints in phytotoxic evaluation. Hassall et al (2005) suggested the use of terrestrial isopods (woodlice) as a tool of ecotoxicological evaluation for contaminated sites.…”

Lettuce (Lactuca sativa) seeds play a significant role in toxicity tests of isolated chemicals, pesticides, and environmental samples. Commonly, the main variables under study are the rate of seed germination and root elongation at the end of five days of exposure. Another organisms used in environmental assessment of soil quality are terrestrial isopods. The parameter evaluated in this assay is usually mortality rate. In this study, we suggest to use the daily number of germinated seeds and wet weight of plants, and feeding measurements (consumption rate, assimilation rate, assimilation efficiency and growth rate) in woodlice (Armadillidium vulgare and Porcellio dilatatus) to detect toxicity of moderately contaminated soil samples. The lettuce seed assay proved to be more efficient in the tested conditions, however, we do not reject the use of feeding parameters in terrestrial isopods in toxicological screening of contaminated soils.

“…For fluoranthene, Sverdrup et al (2003) indicate that a potential soil-screening concentration for vegetation based on phytotoxicity may range from 140 to 650 mg/kgsoil. This would probably apply to naphthalene too, based on an assumption of similar toxic action in receptors.…”
