Open Access Theses & Dissertations
Background & Significance: Inorganic arsenic is a heavy metal naturally found in soil and human exposure to this heavy metal causes adverse effects. Exposure risks are particularly high in developing children. Arsenic is mainly found in bedrock. It is also a by-product of smelting, it is used in cement production, and historically is has been found in crop pesticides. Among other ill-effects, arsenic exposure in humans can cause respiratory diseases, peripheral neuropathy and liver fibrosis. In particular arsenic has been shown in many studies to be a contributing factor in the risk for hypertension in adults however no studies have …

Comparison Of Blood Lead Levels Between Children In An Urban Setting And Children In A Rural Setting, Juan Manuel Alvarez
Open Access Theses & Dissertations
Environmental heavy metal exposure is a public health problem that is of great concern because it is highly toxic for children. The urban setting in downtown El Paso is historically known to be contaminated through various sources of contamination of heavy metals. The goal of this study was to compare whether children in a historically contaminated urban downtown area had significantly increased levels of lead exposure as compared to children in a demographically similar rural area approximately 20 miles north of the urban center, while controlling for gender and age. Cadmium and mercury were also measured for comparison purposes. It …

The Impacts Of Health Status And Exposure To Environmental Toxins On Children's Grade Point Average In El Paso, Texas, Stephanie Elizabeth Clark
Open Access Theses & Dissertations
Studies in the US have found that both exposure to environmental toxins and children's general health status negatively impact children's academic achievement. This Thesis will be made of up two papers. The first examines the impact of exposure to residential air toxins from a variety of sources on student's academic achievement and the second paper incorporates a measure of children's general health status into the statistical model from the first paper. This Thesis employs National Air Toxics Assessment (NATA) risk estimates from a variety of sources and individual-level data collected through a mail survey of fourth and fifth grade school …

Environmental Education Through The Lens Of Diverse Elementary School Students In The United States: A Phenomenographic Study, Brissa Yazmin Quiroz
Open Access Theses & Dissertations
Global environmental change is occurring, putting our planet under pressure. Children need to understand not only why the environment is important, but also their role as citizens of a globalized society and their necessary contribution to solving global problems. Students carry their own perspectives about the environment and education, and these differing perspectives should be a significant topic for environmental education research. Recent research studies have included the conceptualization of nature and the environment through children's eyes; yet, no studies have examined the concept of environmental education through the eyes of diverse children. Minority voices and experiences are not frequently …
