Abstract

Seven heavy metal concentrations (As, Cd, Cr, Cu, Ni, Pb, Zn) were continuously analyzed for twenty rainfall events in 2017~2018 in an urban basin. The overall and dynamic correlations between runoff characteristics and heavy metal concentrations were examined. The peak metal concentration generally appeared in the initial runoff but found to be delayed when the rainfall intensity was low. The rainfall duration had no relationship with either heavy metal concentrations or their total mass. Dynamics of heavy metal mass (load), with the exception of Cu and Zn, showed strong correlation with the 30 minute rainfall intensity (0.60~0.88) and runoff volume (0.74~0.89). While event mean concentration (EMC) showed positive correlation (0.54~0.73) with antecedent dry days (ADD), no significant relationship was found between runoff volume and pollutant concentration. This implies that the pollutants built up on the surface during dry days are washed off even with low rainfall energy. The dynamics of heavy metal and TSS concentrations showed good correlation (0.68~0.87). This result shows that the metals are transported along with solid particles as adsorbate in surface runoff. Regular street sweeping will reduce significant amount of heavy metal loads in urban surface runoff.

본 연구에서는 대전 관평천의 도시유역에서 2017~2018년에 발생한 강우 20건의 유출수를 연속적으로 채취하여 As, Cd, Cr, Cu, Ni, Pb 및 Zn의 중금속 및 총고형물질(TSS) 농도와 유량을 분석하고, 강우특성과 수질 변화의 강우사상별 및 시간별 상관관계를 조사하였다. 일정 강우강도에서 오염물질의 최대농도는 강우 초기에 발생하는 경향을 나타냈으나, 강우량 및 강우강도가 작은 경우에는 일정 시간 경과 후 발생하는 것이 관찰되었다. 강우지속시간은 중금속 농도 및 부하량과 큰 상관성을 보이지 않았다. Cu와 Zn을 제외한 중금속 질량은 강우강도(0.60~0.88) 및 총강우 유출량(0.74~0.89)과 상대적으로 높은 상관관계를 나타냈다. 강우 시 유량가중평균농도와 선행무강우일수 또한 양의 상관성(0.54~0.73)을 보이는 반면, 30분 강우강도로 표현된 시간별 유출량과 TSS 및 중금속 농도는 전혀 상관성을 나타내지 않았다. 무강우 기간 동안 지표면에 축적된 오염물질이 최소한의 강우 에너지에도 세척효과가 발생하여 강우특성과는 무관하기 때문인 것으로 추정된다. 중금속과 TSS 농도의 시간에 따른 변화특성은 상관계수가 0.68~0.87로 양호한 수준을 나타냈다. 이는 고형물질의 이동과 중금속 물질의 이동이 함께 발생한다는 것을 시사하며 동시에 중금속이 고형물질에 흡착되어 이동한다는 것을 의미한다. 따라서 비강우 시에 유역 표면의 고형물질을 청소 등으로 사전에 제거할 경우 하천으로 유입되는 중금속오염물질의 양을 현격하게 저감할 수 있을 것으로 판단된다.
