A method for the integration of satellite vegetation activities observations and magnetic susceptibility measurements for monitoring heavy metals in soil

Source mapping and determining of soil contamination by heavy metals using statistical analysis, artificial neural network, and adaptive genetic algorithm

“…As an important component of urban ecosystems, soil is 9 essential to human existence [1][2][3]. However, soil is subject to 10 human activities causing soil degradation through pollution, 11 erosion, compaction and salinization [1].…”

“…However, soil is subject to 10 human activities causing soil degradation through pollution, 11 erosion, compaction and salinization [1]. It is generally considered 12 as a non renewable resource because the processes involved in soil 13 formation are so slow and recovery strategies are quite complex 14 and expensive.…”

“…It is generally considered 12 as a non renewable resource because the processes involved in soil 13 formation are so slow and recovery strategies are quite complex 14 and expensive. For such reasons, the importance of soil protection 15 is recognized both internationally and in China [1,4]. Q2 16 The most frequent soil contaminants are heavy metals and 17 mineral oil.…”

Detection of Acid Sludge Contaminated Area Based on Normalized Difference Vegetation Index (Ndvi) Value

“…The low NDVI represents the existence or potential occurrence of contamination (D'Emilio et al, 2012). The NDVI value in dry season pattern 1 to pattern 6 in Table 3-1 shows the lowest NDVI in pattern 1 with the value of -0.148 locate in point B1 location, and the highest NDVI reaches 0.386 in pattern 5 occurred in D1 location.…”

“…In the dry season, the NDVI value from 1997 to 2012 is fluctuated as shown in Table 3 The high NDVI value enable to show the health or the thickness of leaf, while the low NDVI value shows the stress and rareness of vegetation (D'Emilio et al, 2012). The low NDVI represents the existence or potential occurrence of contamination (D'Emilio et al, 2012).…”
