Contributions of different pollution sources to each pollution factor of Changtan Reservoir were quantified by APCS-MLR (absolute principal component score-multiple linear regression) model. Research results show that the primary pollution sources of Changtan Rese...

and dry seasons,the daily monitoring data of Yingzai national examination section of Jiuzhou River were chosen.The characteristics of water quality and pollution sources in wet and dry seasons were analyzed by using correlation analysis and absolute principal components-multiple linear regression model ...
The APCS-MLR model was employed to determine the contribution ratio of each source and quantify its contribution to each water quality indicator based on the outcomes of source identification using PCA/FA. According to Figure 4, the determination coefficient (R2) between the parameters that were ob...

The data matrix was also subjected to PMF receptor model using the EPA PMF-5.0 program and the two-way model described was performed for the PMF analyses. Comparison of the obtained results of PMF and APCS-MLR models showed that there were some significant differences in estimated contribution ...
The results of APCS-MLR model showed that the contribution rates of traffic source to Zn, Cr, Ni and Pb were 106.199%, 281.404%, 117.563% and 100.266%, respectively; the contribution rate of agricultural source to Cu was 154.682%. The results are basically the same...
Geostatistical analysis and the APCS-MLR model have apportioned four pollution sources. The Mn and Ni were attributed to natural sources; As and Cr were from agricultural activities; Cu and Zn were originated from natural sources; Cd and Pb were derived from atmospheric deposition. Atmospheric ...
The combination of the acceptor model and geostatistics can effectively analyze the source and contribution rate of heavy metals in farmland soil qualitatively and quantitatively.Journal of Agro-Environment Science霍明珠高秉博乔冬云Sainbuyan Bayarsaikhan...
