Source apportionment and human health risk of PAHs accumulated in edible marine organisms: A perspective of “source-organism-human”

Health Risk Assessment of Heavy Metals in Soil of Lalu Wetland Based on Monte Carlo Simulation and ACPS-MLR

“…The study extracted three major factors using the APCS-MLR model, as shown in Table 7, with a cumulative variance contribution rate of 81.49%. These factors could explain a significant portion of the data's information, with R2 values for all seven heavy metal elements exceeding 0.70, indicating a high level of fit and relatively high model accuracy [50]. Factor 1 contributed 51.13% of the variance and was primarily associated with Cu (0.498), Zn (0.909), Pb (0.937), and Cd (0.875).…”

Quantitative structure-activity relationship model development for estimating the predicted No-effect concentration of petroleum hydrocarbon and derivatives in the ecological risk assessment

“…It is estimated that the concentration of total petroleum hydrocarbons (TPHs) was 1.83 × 10 5 mg/kg in the soils and sediments around the productive oilfields [ 4 , 5 ], which exceeded the Soil environmental quality-Risk control standard of TPHs for development land (826 mg/kg) developed by Ministry of Ecology and Environment of China by 221 times [ 6 ]. A large number of PHDs are easily accumulated in organisms from the polluted environments, and pose potential high risks to high trophic organisms [ 7 , 8 ] and even human [ [9] , [10] , [11] ] through biomagnification [ 12 ], resulting in the decline of ecosystem services function [ 13 ] and the disrupt of the ecological mechanism [ 14 ]. However, accurate risk assessment for PHDs is limited due to the lack of environmental quality limits for specific PHDs.…”
