“…이 중 토양오염은 다른 환경오염에 비하여 오감에 의한 감지가 어렵고 오염물질의 유동성이 낮아 오염 시작 과 문제 발생 간의 시기적 차이가 생기며, 피해가 발생하거 나 오염이 상당히 진전된 이후에야 오염을 인식하게 된다 (Jeong et al, 2015). 토양오염은 지형•지질•수리학적 특성이나 경작활동 등 다양한 현장 특수성에 따라 피해 발생 양상이 달라지므로 (Kim et al, 2015), 피해를 예측하는 토양오염 평가방법이 국가 및 기관별로 다르다. 우리나라는 2009년 이전까지 0.1 N HCl 및 1 N HCl을 이용하여 토양 내 중금속 함량을 측정 하였으나, 이후 왕수(aqua regia)를 이용한 전함량(pseudototal content) 분석법으로 개정하여 토양오염을 평가하고 (Mehlich, 1984;Tack and Verloo, 1995;Ure, 1996;Chojnacka et al, 2005).…”

Environmental geochemists have attempted to select proper soil extraction methods that deeply reflect the bioavailability, phytoavailability, and geochemical mobility of elements for the assessment of heavy metal contamination in soil. However, they are faced with complications during the process due to the complexity of heavy metal forms in soil and diversity in existing soil extraction methods. The present study summarizes the information on soil contaminated with heavy metals in Korea and current research trends on various single and sequential extraction techniques through a literature survey. This work is expected to serve as a fundamental reference for researchers to select an appropriate extraction method for evaluating bioavailability, phytoavailability, and geochemical mobility of heavy metals in soil.

The main purpose of this study was to investigate soil contamination using heavy metal analysis in agricultural fields around industrial complexes in the Jeon-Nam regions in Korea. Ten counties in Jeon-Nam province for soil samples near industrial complexes were Gwangyang, Muan, Yeongam, Hampyeong, Haenam, Naju, Jangheung, Boseong, Yeosu, and Damyang. At agricultural field sites soil samples were collected in the spring of 2018 at two soil depths (0-15 cm and 15-30) within a 500-and 1000-meter radius next to industrial complexes before planting. All soil samples were analyzed for the 8 heavy metals including arsenic (As), cadmium (Cd), chromium (Cr), cupper (Cu), nickel (Ni), lead (Pb), mercury (Hg) and zinc (Zn). The results showed that the heavy metal concentrations were below the levels of Soil Contamination Warning Standard (SCWS) for agricultural lands (Region 1) which is regulated by Soil Environment Conservation Law (SECL) established by Ministry of Environment (MOE), Korea. Other heavy metal indexes such as soil pollution index (SPI), pollution index (PI), and pollution load index (PLI) were evaluated to determine contamination of soils due to heavy metals. If SPI is less than 1.0, then soil heavy metal concentration is within the levels of soil contamination warning standard. In this study, SPI is less than 1.0 that means soil is not contaminated. Second, PI for the studied soils is less than 1.0, which classified into "Classification index 1" which means uncontaminated soils. Lastly, PLI for studied soils is between 0.10 and 0.24, classified into "Classification index 2" which is unpolluted soil. For interpreting the PI, the heavy metal concentration and background concentration should be used very carefully if the heavy metal concentration in the soil is lower than the background concentration. In this case, PI value of Hg can mislead interpretation if the soil heavy metal concentration is less than the background concentration. For example, Hg concentration for the background concentration is 0.025 mg kg -1 and Hg concentration for studied soils ranged from 0.000 to 0.004 mg kg -1. Further research is needed to continue to monitor soil heavy metal distribution near industrial complexes in Jeon-Nam province of Korea.
