Arbelaiz et al [10] related the similarly low values of IFSS in the case of a polypropylene system to a week fibre-matrix adhesion, as initially assumed.
Ray et al. reported similar observations and proposed that the fibres act like flaws in the matrix, when the volume fraction of reinforcing fibres is lower than a certain critical quantity [12].

In this study, the chlorophyll content of seedlings under ozone and drought stress kept stable or decreased, which was similar with the report from Inclán et al [21].
These results were similar with the report by Zhuang et al. who studied Phyllostachys edulis and Oligostachyum lubricum under ozone stress [29].

The synthesis of Si from ash was based on the study of Maulion et al. [8] with minor modification.
This is similar with the study of Rovani et al. [15] where the percent nitrate decays exponentially at 6th cycle with percent removal of less than 50% due to partial removal of CTAB on nanoparticle surface during adsorption and isolation.
