Abstract

Samples (river water, tap water, soil, sediment, fish and shellfish) collected in Downstream Area of Nakdong River were analyzed for organochlorine pesticides by G.C. equipped with electron capture detector. Residue levels of organochlorine pesticides in the river water and tap water ranged from less than detection limit (ND) to 56ppt. Total BHC concentration in the river water and tap water were found to increase in summer and decrease in winter. The variation appeared to be related to rain fall. ${\alpha}-BHC\;and\;{\beta}-BHC$ concentration in the soil were ND-3.3ppb and ND-769.7ppb, respectively. ${\alpha}-BHC\;and\;{\beta}-BHC$ concentration in the sediment were ND-2.0ppb and ND-409.9ppb, respectively. Concentration factor of total BHC in the sediment ranged from 83 to 3213. In fish, Carasssus carassius and shellfish, Anodonta woodiana(Lea) the concentration factor of ${\beta}-BHC$ and total BHC were 2,609, 435 and 3,261, 375, respectively.

낙동강(洛東江) 하류지역(下流地域)에서 낙동강(洛東江)물, 수도물, 토양(土壤), 저질(底質) 및 붕어와 뻘조개에 대(對)한 유기염소계살충제(有機鹽素系殺蟲劑) 농약(農藥)을 G.C-ECD로 분석(分析)하였다. 수중(水中) 잔류염소계(殘留鹽素系) 농약중(農藥中) 주(主)로 BHC만 검출되었는데, 이들 농약(農藥)의 잔류농도(殘留濃度)는 $ND{\sim}56ppt$로 공중보건(公衆保健)에 해(害)를 줄만 한 것은 아니다. 낙동강(洛東江)물과 수도물의 월별(月別) total BHC 농도(濃度)는 여름이 높고 겨울로 갈수록 낮았으며, 강수량(降水量)과는 약(弱)한 양의 상관성(相關性)을 나타냈다. 토양(土壤)에서 ${\alpha}-BHC$${\beta}-BHC$$ND{\sim}3.3ppb$$ND{\sim}769.7ppb$이었으며 저질(底質)에서 ${\alpha}-BHC$${\beta}-BHC$$ND{\sim}2.0ppb,\;ND{\sim}409.9bbp$이었다. 각(各) 지점(地點)에서 저질(底質)로의 total BHC 농축계수(濃縮係數)는 $83{\sim}3,218$이었고, 강열감량(强熱減量)과는 양(量)의 상관성(相關性)이 있었다. 붕어에서 ${\beta}-BHC$와 total BHC의 농축계수(濃縮係數)는 각각 2,619와 435 그리고 뻘조개에서 두가지 BHC 잔류성분(殘留成分)의 농축계수(濃縮係數)는 각각 3,261과 375였다.
