FIGURE 1: The migration pathways of soil contamination On the other hands, South Korea has various laws and regulations related to heavy metals contaminations. They are Soil Environmental Conservation Act(for soil), the Framework Act on Environmental Policy(for river water and lake water) and Act on Underground water(for underground water). There are applicable laws and regulations depending on the target of each pollution, however, there are some problems which a lack of consideration for crops. Currently, the surface soil and groundwater are the object where is measured contaminations. But since crops are grown in the unsaturated zone as shown in Fig. 2 where water and air are mixed together with soil particles, it is important to figure out the contamination characteristics of pore water which is actually absorbed by crops. Recently, many researchers have concerned this problem.(Huynh et al. 2008, Ye et al. 2011, Zhu et al. 2011, Khim et al. 2001) FIGURE 2: Characteristics of the soil systems considering the crops Therefore, in this study, degree of contamination of pore water is measured and is compared with contamination of soil particles and dilution water (wetted soil : water = 1 : 3).
2. Materials and Method 2.1. Study area Two specific samples are used in this study – marine sediment and paddy field soils. The marine sediment soil samples (PH) are collected from seabed sediment in Young-il Bay, Pohang, southeastern coastal part of South Korea. And the paddy field soil samples (SW) are obtained from a farm in Suwon, Gyeonggi-do, South Korea. The sampling locations are shown in Fig. 3 Suwon Pohang FIGURE 3: Locations of sampling sites 2.2. Sample collection and pretreatment The samples taken from each site were prepared by three different types - soil particles, dilution water and pore water – to measure the concentrations of heavy metals. Pretreatment methods for each of the sample are as follows. Soil Particles The soil particles sample was dried while more than 24hr in oven which can be kept inner temperature constant about 110℃ to remove moisture. And then the dried soil is passed through a sieve #100 (150μm) and is taken 10g in passing. Dilution water The dilution water sample was prepared by passing through the filter paper after mixing with distilled water and wetted soil(wetted soil : water = 1:3). Pore water There are many methods to obtain of pore water as shown Table 1. And many researchers have tried to develop device obtaining pore water more easily. (Hesslein 1976, Robbins and Gustinis 1976, Bottomley and Bayly 1984, Bertolin, Rudello and Ugo 1995, Bufflap and Allen 1995a, Bufflap and Allen 1995b, Teasdale et al. 1995, Angelidis 1997, Patrick H 2002) In this
