Research Design & Methods: In total, 305 migrants from Venezuela living in Peru completed the online questionnaire. It contained 21 items that evaluated the variables to explain the EI. In the study, we employed the partial least squares structural equation modelling (PLS-SEM) technique. Findings: We found that ATT (0.591) and PCS for entrepreneurship (0.204) showed a direct and significant influence on ESE, while ESE showed a direct and significant influence (0.823) on the EI. The research model explained 67.7% of the EI. The analysis using bootstrapping technique showed the significance of the path coefficients. Implications & ...

This study evaluated the concentration of toxic elements in soil samples from agricultural fields in the districts of Sachaca, Socabaya, Hunter, Quequeña, Yarabamba, Characato and Tiabaya in the city of Arequipa, Peru. The ecological risk, enrichment factor (EF), geo-accumulation index (Igeo) and integrated ecological risk index (RI) were estimated, while the health risk was determined with hazard coefficient (HQ) and hazard index (HI) values. Seven soil samples were collected in July 2019 and 17 toxic elements were analyzed in an accredited laboratory using the inductively coupled plasma-mass spectrometry (ICP-MS) methodology. The results were compared with environmental samples where no element exceeded what is established in the standard. The enrichment factor (EF), according to the background of Wedepohl, indicated that As (12.26 ± 3.66) presented a severe enrichment (high) in agri...
