선인장 및 몇 가지 식물이 컴퓨터 모니터로 부터 발생되는 ELF 및 VLF 전자파의 차단효과에 미치는 영향이 조사되었다. 모니터의 정면에서 전자파가 가장 많이 방출되었으며, 차단효과의 검증을 위해 식물과 다른 대상물들은 모니터의 정면 혹은 측면에 두었다. 측정된 모든 식물에서 모니터 발생의 전자파 중 자계 (magnetic waves) 차단에는 전혀 효과적이지 못한 것으로 나타났다. 한편, 선인장의 크기, 형태, 그리고 배치방법에 따라서는 약간의 전계(electric waves) 차단효과가 있는 것으로 나타났으나, 경미하여 TCO의 규정치(electric field: 10V/m and 1V/m in ELF and VLF, respectively)에는 미치지 못하기 때문에 실용화하기에는 어려운 것으로 판단된다.

Effects of cacti and a few indoor plants on the protection of the harmful electromagnetic waves (ELF: extremely low frequency and VLF: very low frequency bands) radiated from the monitor of computer were investigated in indoor condition. The front screen of monitor evoked the highest amounts of electromagnetic waves as compared to other positions. Therefore, plants and other objects were placed on the front or side of monitor in order to measure electromagnetic waves. It was shown that all plants including cacti did not have any effect on the reduction of magnetic waves in both ELF and VLF, regardless of species and varieties, sizes, and dispositions. In the case of electric waves, however, there was a little reduction by cacti, depending upon several treatments mentioned before, but the measured values did not reach below values ruled by TCO (Tjatemannens Central Organization, Swedish Confederation of Professional Employees; electric field: 10 V/m and 1 V/m in ELF and VLF, respectively).
