Unsuitably products were spinach(21.0%), perilla leaf(17.3%), ulgari(13.6%), leek(12.4%), crowndaisy(12.4%), asterscaber(12.4%), chard(11.1%). Detected pesticides were procymidone(3.9%), endosulfan(2.6%), chlorfenapyr(2.2%), bifenthrin (1.3%), cypermethrin(0.7%), metalaxyl(0.9%), azoxystrobin(0.3%) and chlorothalonil(0.7%). Sixty-four pesticides were detected and 11 pesticides were newly detected in 2007. Thirty-one pesticides in agricultural products exceeded their MRLs.

Fig. 7에서는농산물분류별검출율에서는엽채류 (11.3%), 과채류 (4.4%), 엽경채류 (2.0%) 감귤류 (0.5%) 순으로엽채류와과채류가평균부적율 4.1% 보다높게검출되어상대적으로농약사용이많음을알수있으며, 2007년도새로추가된농약 Spiromecifen은유기염소계살충제로담배나방및토양해충방제용으로사용하며환경호르몬으로분류되어있고수질오염성농약으로지정되어있어사용을규제하고있으며, 잔류성이길어생식하는엽채류나과채류에서의사용은피하고근채류에서도마찬가지로사용을금하고있는농약이다. Table 1의농산물분류에따라엽채류는 37종 1,545을검사하여 342건의농약이검출되어 22.1% 의검출율과 23 종 102건 (6.6%) 에서농약허용기준이상검출되었으며, 엽경채류는 14종 311건에서검사하여 7종 60건에서잔류농약이검출되어 19.4% 검출율과 4종 18건에서잔류허용기준을초과하여 5.8% 의부적율을나타내었다. 과채류는 12 종 594건을검사하여 10종 133건에서잔류농약이검출되어 22.4% 의검출율을보였고, 이중 1종 2건이잔류허용기준을초과하여 0.3% 의부적율을보였다. 그외곡류나두류, 버섯류에서는농약이검출되지않아최근수년간의경향과비슷하였다. 채소류에서는달래와머위가 9건중에서 3건에서기준이초과되어 33.3% 로가장높았고, 취나물이 40건을검사하여 10건에서기준이초과되어 25% 의부적율을나타냈다, 또한전년도에이어비름나물도 19건을검사하여 21.1% 의높은부적율을나타내고있으며, 부추, 깻잎, 쑥갓, 얼갈이등에서도 10% 이상의높은부적율을나타났다. 파, 근대, 머위에서는부적율의증가는분석기술의향상과허용기준의강화와농약성분의유효등록작물이외에서검출되면부적합것으로기준규격이강화되어부적율과검출율이높아지게되는원인 11) 으로볼수있고머위, 케일, 달래등에서는검출농약중에서 75% 이상의부적율이나타나는반면에고추에서는부적율이 3% 인것이특이할만한사항이었다. 고추에서낮은부적합율은엽채류에비해질량대비표면적이작기때문이고또한작물의생육에따른희석효과를고추로비교한보고와도유사한다 11). 전년도와같이 procymidone(17.1%), endosulfan(14.8%) 과 chlorfenapyr(11.4%) 이검출빈도가높음을알수있다. Procymidone, endosulfan과 chlorfenapyr 등은유기염소계
