현재 GM작물의 안정성 평가는 어떻게 이루어지고 있는가? | GM작물에서 도입된 유전자의 영향에 의하여 발생할 수 있는 비의도적인 성분 변화를 조사하기 위한 방법들이 발전되고 있다. 현재까지는 GM작물의 안전성 평가법으로는 OECD의 가이드라인에 명시되어 있는 주요 영양성분과 항영양소, 독성물질, 이차대사 산물과 같은 알려진 성분을 비교작물과 비교하는 표적성분 접근법이 이용되고 있다. 그러나 표적성분 접근법은 분석 가능한 물질의 제한성과 알려지지 않은 항영양소나 독성물질 등을 확인할 수가 없다. | |
생명공학 작물의 재배 면적 변화는 어떠한가? | 이 후로 GM작물에 대한 수요가 증가하면서 GM작물의 재배를 승인하는 국가와 재배 승인되는 작물의 종류가 증가하였다(Aldemita 2015). 결과적으로 1996년 170만 ha였던 재배면적이 2017년 1억 8980만 ha로 약 112배 증가하였으며(ISAAA 2017), 2017년까지 가장 많이 재배된 GM작물은 대두, 옥수수, 면화, 카놀라, 알파파이며 이외에 사탕무, 파파야, 감자 등이 재배되었다(ISAAA2017). 지금까지 주로 제초제 내성 및 해충저항성 특성을 가진 작물이 주로 개발되었으며, 최근에는 영양조성이나 기능적 특성이 개선된 작물 개발이 점차 증가하고 있다(Dunwell2014). | |
2017년 까지 가장 많이 재배 된 GM작물 종류는 무엇인가? | 이 후로 GM작물에 대한 수요가 증가하면서 GM작물의 재배를 승인하는 국가와 재배 승인되는 작물의 종류가 증가하였다(Aldemita 2015). 결과적으로 1996년 170만 ha였던 재배면적이 2017년 1억 8980만 ha로 약 112배 증가하였으며(ISAAA 2017), 2017년까지 가장 많이 재배된 GM작물은 대두, 옥수수, 면화, 카놀라, 알파파이며 이외에 사탕무, 파파야, 감자 등이 재배되었다(ISAAA2017). 지금까지 주로 제초제 내성 및 해충저항성 특성을 가진 작물이 주로 개발되었으며, 최근에는 영양조성이나 기능적 특성이 개선된 작물 개발이 점차 증가하고 있다(Dunwell2014). |
