Figure 5From: Distribution of polycyclic aromatic hydrocarbons in subcellular root tissues of ryegrass (Lolium multiflorumLam.)Proportions of phenanthrene (a) and pyrene (b) distributed in cell water soluble fraction, wall and organelle as a function of uptake time. The proportion of PAHs was calculated from the measurement of PAH in each fraction to the total amount in ryegrass root cells.Back to article page
