Blood Lead Levels In Minority Children: A Case Of Environmental Racism, Erick Rivera
Blood Lead Levels In Minority Children: A Case Of Environmental Racism, Erick Rivera
Sociology & Criminal Justice Theses & Dissertations
Racial minorities in the United States have suffered from being disadvantaged. Among these disadvantages is environmental racism. This includes minority communities being ‘sacrifice zones’ for toxic waste and being exposed to lead poisoning. The purpose of this study is to examine differences in blood levels between white children and children of color. This research will follow a bivariate model for the first research question, “Do youth of color (under the age of 18) have higher BLLs than white children?” The bivariate model will look at the relationship between ethno-racial group and BLLs. Specifically, an analysis of variance (ANOVA) will be …

Currently, effects of nanomaterials and their ions, such as silver nanoparticles (Ag NPs) and silver ions (Ag+), on living organisms are not yet fully understood. One of the vital questions is whether nanomaterials have distinctive effects on living organisms from any other conventional chemicals (e.g., their ions), owing to their unique physicochemical properties. Due to various experimental protocols, studies of this crucial question have been inconclusive, which hinders rational design of effective regulatory guidelines for safely handling NPs. In this study, we chronically exposed early developing zebrafish embryos (cleavage-stage, 2 hours post-fertilization, hpf) to a dilution series of …

The goal of this project is to explore a new method to efficiently remove Pb(II) ions from water by processing Undaria pinnatifida into immobilized beads using sodium alginate and calcium chloride. The resulting biosorbent was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS). Using immobilized U. pinnatifida, we investigated the effect of various factors on Pb(II) ion removal efficiency such as temperature, pH, ionic strength, time, and underlying biosorption mechanisms. For Pb(II) ion biosorption studies, Pb(II) ion biosorption data were obtained and analyzed using Langmuir and Freundlich adsorption models. It …
