Abstract

There is a continuous rise in the commercialization of living modified (LM) organisms worldwide. While LM plants have not yet been cultivated in South Korea, research, development, import of products, and registration of related research facilities are progressing. LM plants should be tested in greenhouses and fields during development. Furthermore, environmental risk assessment and safety management should be performed before their release into the environment. Research on LM plant development is conducted in laboratories as well as confined greenhouses and fields. Safety management regulations are provided as combination standards for the LMO Act in each research district. The accidental release of the LM petunia in Japan was a significant incident related to LM plant research. It implies that normal plants within the distance of crossing should be regarded as LM plants. In the United States, LM creeping bentgrass was released into the environment, thus necessitating the establishment of stringent measures to prevent the scattering of LM plant seeds by wind or other mediums. In South Korea, LM Zoysia and LM cotton were released through rainwater. Therefore, safety measures that prevent LM seed mixing and plant vegetative propagules escaping into the environment via rainwater must be established. Preventing the dispersal of unapproved LM plants requires significant time, expenditure, and effort. Researchers should first identify the impact of LM plants on the ecosystem, and steps to avert their environmental release must be implemented.

전 세계적으로 LMO (Living Modified Organisms)의 이용과 상업화는 지속적으로 증가하는 추세이다. 국내에서 LM 식물의 상업적 재배는 아직 이뤄지고 있지 않으나 연구개발 및 수입, 연구시설의 신고 등은 활발히 진행되고 있는 실정이다. LM 식물은 개발 및 환경위해성 평가 단계에서 온실과 야외 포장에서의 실험이 요구되나 개발 중인 단계에서는 아직 환경에 대한 안전성이 입증되지 않아 환경방출에 대한 안전관리가 요구된다. LM 식물의 개발 연구는 일반적으로 실험실, 격리온실, 격리포장에서 수행되며 각 연구 구역마다 LMO법 통합고시 등에서 안전관리 규정이 마련되어 있다. LM 식물 연구 사고사례 중 일본의 LM 페튜니아 유출 사고는 LM 식물 연구 도중 교잡 가능 거리에 있는 일반 식물은 LM 식물로 간주하여 취급되어야 함을 시사하고 있으며, 미국의 LM creeping bentgrass 유출 사례는 바람 등에 의해 종자의 산포가 용이한 LM 식물의 경우 종자 비산에 대한 강력한 방지 대책 수립의 필요성을 시사한다. 또한 국내 LM 들잔디 유출과 LM 면화 유출 사례는 빗물 등에 의한 식물 영양번식체 유출 및 LM 종자 혼입에 대한 안전 대책 수립의 필요성을 제시한다. 미승인된 LM 식물의 환경방출에 따른 확산은 제거와 복구에 많은 시간과 비용, 노력이 요구된다. 따라서 최근 생명공학기술을 적용하는 LM 식물들이 다양화됨에 따라 개발자 및 연구자는 환경생태계에 미치는 영향을 사전에 파악하고 환경방출 방지 등 철저한 안전관리가 요구되는 바이다.
