Forecasting of Ecological Risk of Heavy Metal Contamination to the Tidal Flat of Yalu River Estuary by Using Markov Chain Grey Model

Abstract:

From January 2012 to April 2013, the heavy metal contents of Venerupis variegata which was used as bio-indicator were determined by using incomplete digestion - AAS method. The correlation of the heavy metals between the surface sediments and the Venerupis variegata was analyzed by using Pearson method and Markov chain model. The potential ecological risk of heavy metal pollution was evaluated in the Yalu River estuary. The results showed that the recovery rate was from 94.3 to 107.2%, RSD<4.3% and the correlation coefficients of Cd, Pb and Cr were 0.9175, 0.8911, 0.8146, when the samples were digested with the mixed acid at 90 - 120°C
