This paper compares black oil with orimulsion, and explores solid combustion products of the latter in several aspects. Orimulsion ash was analyzed by means of X-ray diffraction, and concentrations of soluble metals were determined. Effects of orimulsion ash solution on germination and growth of wheat, rye and vetch were investigated. Concentrations as low as 0.005% orimulsion ash solution have stimulating effects on all three kinds of seeds. However, at 0.05% concentration orimulsion ash solution inhibits growth of seeds, and at 0.5% it blocks germination of seeds completely. As far as fall out of orimulsion ash is concerned it may not reach toxic concentrations in the short term. Usage of orimulsion should not cause immediate environmental damage, however, it is necessary to perform additional research in order to determine any potential dangers of orimulsion usage in the long term.
