In Korea, over 4,700 animal carcass disposal sites were installed until 2011 due to the outbreak of foot and mouth disease. Due to the putrefaction of buried animals, the leachate containing veterinary antibiotics may release into surrounding environments. Antibiotic residues in the environment caus...

가축전염병인 구제역(FMD, Foot and mouth disease) 및 조류독감(AI, Avian influenza) 등의 발생으로 이루어진 조치는? | 2000년 이후 국내에서는 가축전염병인 구제역(FMD, Foot and mouth disease) 및 조류독감(AI, Avian influenza) 등의 발생으로 인한 전염병의 확산방지를 위해 가축의 대대적인 살처분을 실시하였고, 이 후 사체로부터 병원체가 확산되는 것을 막기 위해 대규모 매몰을 실시하였다. 이로 인해 전국에 조성된 가축 매몰지는 2011년 8월 말 기준 약 4,700여개소로 보고되었다(Kim과 Kim, 2013). | |
항생제는 무엇인가? | 항생제는 미생물에 의해 생성된 물질로 세균 및 타 미생물의 성장과 활동을 억제함으로써 인간 및 동물의 질병예방 및 치료, 성장촉진에 사용되는 물질이다(Thiele-Bruhn, 2003; Seo 등, 2007; Kwon 등, 2011). 농림축산식품부(MAFRA)에 따르면 국내에서 축산용으로 사용된 항생제 판매량은 2012년 기준 936톤으로 조사되었으며, 이 중 tetracycline계열 및 sulfonamide 계열 항생제의 사용량이 각각 282톤, 102톤으로 전체 사용량의 약 41%에 달하는 것으로 조사되었다(MAFRA, 2013). | |
토양 내에 잔류하는 가능성이 제일 높은 물질은? | 이와 같은 특성은 토양 내에 다량으로 존재하는 다가 양이온에 의해 tetracycline 계열의 항생제가 결합되어 잔류할 수 있음을 나타낸다. Lee 등(2009)은 토양컬럼을 이용한 항생제 이동성 연구보고에서 이와 같은 특성으로 인해 tetracycline 계열 항생제의 토양에 대한 흡착계수(Kd)값이 sulfonamide 계열에 비해 상대적으로 높아 심토로 용출되지 않으며 표토에 흡착되어 잔류한다고 하였다. 또한 sulfonamide계열에 비해 tetracycline 계열의 항생제는 토양 및 유기물질에 대한 흡착친화력이 상대적으로 높아 토양에서의 잔류가능성이 높은 것으로 보고된 바 있다(Kim과 Carlson, 2007b; Kim 등, 2010b). |
