Removal Of Arsenic (Iii) And Arsenic (V) From Aqueous Solution Via Common Sunflower Helianthus Annuus By Phytoremediation, Irving A. Vazquez Hurtado
Removal Of Arsenic (Iii) And Arsenic (V) From Aqueous Solution Via Common Sunflower Helianthus Annuus By Phytoremediation, Irving A. Vazquez Hurtado
Theses and Dissertations
Phytoremediation provides a cost-effective, non-invasive technique to remove contaminants from the soil and groundwater. Sunflowers are fast growing and have a showed effective at removing various pollutants from soil, including lead and other heavy metals. Health issues related to arsenic are mainly attributed to exposure of arsenite, whereas arsenate is much less toxic. The common sunflower Helianthus annuus was the species used to remove both arsenic (III) and As(V) ions from hydroponics solutions. In the present study sunflower seeds were germinated for a week, placed under the sun for a day and subsequently placed in a nutrient solution to aid …

The rising number of chemicals that humans are exposed to on a daily basis, as well as advances in biomonitoring and detection technologies have highlighted the diversity of individual exposure profiles (complex body burdens). To address this, the toxicological sciences have begun to shift away from examining toxic agents or stressors individually to focusing on more complex models with multiple agents or stressors present. Literature on interactions between chemicals is fairly limited in comparison with dose-response studies on individual toxicants, which is largely due to experimental and statistical challenges. Experimental designs capable of identifying these complex interactions are often avoided …
Assessment Of Human Exposure To Perchlorate And Perfluoroalkyl Substances In The United States : Biomonitoring And Environmental Monitoring Approaches, Qian Wu
Legacy Theses & Dissertations (2009 - 2024)
Perchlorate is an oxidant in solid fuels and explosives and is produced in large quantities worldwide. Perchlorate is a ubiquitous environmental contaminant and is present in water, food, indoor environment and humans. Human exposure to perchlorate is a concern due to its ability to disrupt the thyroid gland functions.

A Study Of Human Exposure To Benzo(A)Pyrene (Bap) Through Different Pathways. Part A ; Assessment Of Benzo(A)Pyrene (Bap) Exposure Through Urine Analysis With The Hydriodic Acid Reduction Reaction. Part B, Shao-Keng Liang
Theses
PART A: An investigation of total human exposure to an environmental pollutant is described. The study is being conducted in a community impacted by a foundry suspected to be a dominant local source of benzo(a)pyrene (BaP). The research aims to assess the relative contributions of indoor and outdoor sources and to measure BaP in media including indoor air, outdoor air, food and water.
PART B: A method for biological monitoring of exposure to benzo(a)pyrene, a representative polycyclic aromatic hydrocarbon (PAH), has been developed. The analytical procedure includes extraction of PAH and PAH metabolites from urine using commercial cartridges containing c …
