“…This effect was also observed for cucumber seeds in T3, where intermediate compounds produced by the biodegradation may be more toxic to seed germination than the original substance and also, may have contributed to combined toxicity of different compounds through synergisitc or antagonistic effects (Lapinskiene et al, 2006;Plaza et al, 2005). Result corroborates the findings of Tamada et al (2012), who reported increase in the inhibition percentage of the germination on soil contaminated with biodiesel, after 180 days of biodegradation by autochthonous microorganisms.…”

The evaluation soil quality after bioremediation processes solely on chemical data does not include the effects of toxic substances in organisms. Thus, ecotoxicological assays with seeds are applied to assess the effect of toxic substances in organisms according to their germination sensitivity. The objective of this study was to evaluate a contaminated soil with diesel, biodiesel and waste lubricat oil in ecotoxicological bioassays using seeds of Cucumis sativus (cucumber), Brassica oleracea (kale) and Barbarea verna (cress) as test organisms. The sample of contaminated soil was buried to allow contact with microorganisms that are naturally present in the soil and can be capable to biodegrade the contaminant. Each soil sample was removed monthly and the potential toxicity of contaminants was evaluated by examining germination rates according to biodegradation time in soil. The results indicate that the species Barbarea verna is not a good test organism due to its low germination rate. The study suggest that the contact of waste lubricant oil and diesel with the embryo was hampered by the seed coats and the hydrophobicity these substances, preventing the entry of substances which may be toxic to the embryo. Also, Cucumis sativus and Brassica oleracea showed that after two months of biodegradation, biodiesel is the most toxic contaminant during seed development.

“…The stimulating effect of biodiesel in the mixture with diesel fuel was visible mainly with its 20% and 50% addition, both in lower and higher dose of contamination. This is likely to be the result of a lower toxicity of biodiesel in relation to diesel oil (Lapinskiene et al 2006). Conventional fuel has an adverse effect on the water-air relations in the soil, creating an impermeable oily film layer around the seeds or…”

“…This could explain the reduction of kernel masses at the Rahkakorpi test site. Both the rapeseed oil and rapeseed oil methyl ester will also change the pH level of the soil and therefore also have an effect on the micro-organisms and their interrelationships (Lapinskiene et al 2006). The contaminants used might have also therefore affected the normal metabolism of the microbes in the soil.…”

“…The renewable liquid fuels (biodiesel and bio-oils) are said to be biodegradable (Sendzikiene et al 2007) but nevertheless these still have an impact on the ecosystem (plant growth etc.) if an oil or fuel spill happens (Lauhanen et al 2000, Lapinskiene et al 2006, Peterson and Möller 2004, Gong et al 2008.…”

The aims of this study were to determine the phytotoxicity of stored rapeseed (Brassica rapa) oil (RSO) and rapeseed oil methyl ester (RME) after "spill like" contamination on the growth of barley (Hordeum vulgare) and the biodegradability of these substances in OECD 301F test conditions and in ground water. Rapeseed oil and rapeseed oil methyl ester were both stored for a period of time and their fuel characteristics (e.g. acid number) had changed from those set by the fuel standards and are considered to have an effect on its biodegradation. The phytotoxicity was tested using two different types of barley cultivars: 'Saana' and 'Vilde'. The phytotoxic effect on the barley varieties was determined, after the growth season, by measuring the total biomass growth and the mass of 1000 kernels taken from the tests plots. Also visual inspection was used to determine what the effects on the barley growth were. These measurements suggest that both RSO and RME have a negative impact on barley sprouts and therefore the total growth of the barley. RSO and RME both decreased the total amount of harvested phytomass. The weight of 1000 kernels increased with low concentrations of these contaminants and high contamination levels reduced the mass of the kernels. The results of these experiments suggest that the stored rapeseed oil and rapeseed oil methyl ester are both phytotoxic materials and therefore will cause substantial loss of vegetation in the case of a fuel spill. The RSO and RME biodegraded effectively in the measurement period of 28 days under OECD test conditions: the degree of biodegradation being over 60%. The biodegradation in the ground water was much slower: the degree of biodegradation being about 10% after 28 days.
