4. Conclusion
Significant changes in EO content were observed under the
level of 100 mg Pb kg−1 in the soil, which reduced the EO content.
However, under levels of 500 and 1000 mg Pb kg−1 and with
AMF inoculation, an increase in EO content was observed. Without
AMF inoculation and Pb, the major EO component was citral. However,
under high Pb levels, and with AMF inoculation, the major EO
component was geranial.
