Biochar (BC) from biomass pyrolysis is a carbonaceous material that has been used to remove various contaminants in the environment. The eliminatory action for burcucumber (Sicyos angulatus L.) as an invasive plant is being consistently carried out because of its harmfulness and ecosystem disturbanc...

항생물질이 신흥 유기오염물질로 인식되고 있는 이유는? | 신흥 유기오염물질로 인식되고 있는 항생물질(antibiotics)은 미생물에 의해 생성된 물질로 세균 및 타 미생물의 성장과 활동을 억제하여 인간과 동물의 질병예방 및 치료에 사용되는 물질이다(Thiele-Bruhn, 2003; Seo 등, 2007; Lim 등, 2009). 그러나 물질 고유의 대사특성상 투여된 양의 일부만이 체내에서 사용되며 나머지는 체외로 배출된다(Pei 등, 2006; Kim 등, 2011). 배출된 항생물질은 다양한 경로를 통해 환경 중으로 유입되며 내성박테리아 생성 등을 통해 인간과 생태계에 위협을 초래한다(Kim 등, 2010; Kim 등, 2012b). 이 같은 위험성으로 인해 최근 들어 항생물질에 대한 모니터링 연구가 진행되어 왔다. | |
바이오차란? | 바이오차(bioChar)는 제한된 산소 조건에서 바이오매스를 700°C이하의 온도로 열분해(pyrolysis)하였을 때 생성되는 고형물로, 탄소의 함량이 일반 유기물보다 상대적으로 높다(Lehmann과 Joseph, 2009). 특히, 바이오매스에 함유된 분해가 용이한 탄소 (labile C)는 열분해 과정을 통해 난분해성 탄소(stable C)로 변환되므로, 바이오차를 토양에 투입하는 경우 탄소의 지중저장을 통해 온실가스 발생을 억제할 수 있다(Lehmann, 2007). | |
항생물질 흡착제로써 활성탄의 단점은? | 국내에서도 환경 중 잔류 항생물질 모니터링 연구가 보고된 바 있으며(Choi 등, 2008; Lim 등, 2009; Lee 등, 2010; Ok 등, 2011), 이를 제거하기 위한 방법으로 수질 중 항생물질에 대하여 활성탄(activated carbon)을 이용한 흡착 등이 주로 적용되고 있다(Son 등 2008a; 2008b). 그러나 활성탄은 700°C이상의 열분해 조건에서 생산되어 에너지 소모가 크며 이 때 물리·화학적 활성화 과정을 수반하므로 생산단가가 높아 (Lehmann과 Joseph, 2009; Ahmad 등, 2012a) 이를 대체할 수있는 경제적인 소재의 개발이 필요하다. |
