Alteration of the emission of volatile organic compounds (nmol m−2 s−1) from foliage of Petroselinum crispum (a), Anethum graveolens subsp. hortorum (b) and Apium graveolens (c) in response to microwave irradiations at bands corresponding to wireless router (WLAN) and mobile devices (GSM) (presentation of statistical differences as shown in Fig. 2). Each number corresponds to a particular volatile compound as follows: 1. 1-hexanol; 2.
(Z)-3-hexen-1-ol; 3. (E)-2-hexenal; 4. α-pinene; 5. camphene; 6. β-myrcene; 7. β-pinene; 8. α-phellandrene; 9. Δ-3-carene; 10. D-limonene; 11.
para-cymene; 12. β-phellandrene; 13. (E)-β-ocimene; 14. 1,8-cineol; 15. iso-bornyl acetate; 16. longicyclene; 17. caryophyllene oxide; 18. α-selinene; 19. (Z)-β-farnesene; 20. α-caryophyllene; 21. geranylacetone.
* and # demonstrates statistically significant differences between the microwave irradiated plants and control plants and between WLAN and GSM irradiated plants respectively (P < 0.05).
