Arsenic Contamination In Groundwater In Vietnam: An Overview And Analysis Of The Historical, Cultural, Economic, And Political Parameters In The Success Of Various Mitigation Options, Thuy M. Ly

Pomona Senior Theses

Although arsenic is naturally present in the environment, 99% of human exposure to arsenic is through ingestion. Throughout history, arsenic is known as “the king of poisons”; it is mutagenic, carcinogenic, and teratogenic. Even in smaller concentrations, it accumulates in the body and takes decades before any physical symptoms of arsenic poisoning shows. According to the World Health Organization (WHO), the safe concentration of arsenic in drinking water is 10 µg/L. However, this limit is often times ignored until it is decades too late and people begin showing symptoms of having been poisoned.

This is the current situation for Vietnam, …

Northern Fulmars (Fulmarus Glacialis) As Bio-Indicators Of Endocrine Disrupting Plasticizers In The Marine Surface Environment., Olivia Feinstein

Summer Research

The plastics that make up over 10% of human waste are synthesized with phthalate plasticizers which are utilized in plastics as an additive to improve durability and flexibility. Many phthalates have been identified as endocrine disrupting chemicals (EDCs) and studies have shown dramatic deleterious effects as a result of species exposure to growing numbers of EDCs in the environment. Northern Fulmars (Fulmarus glacialis) are a northern hemisphere seabird species that forages opportunistically, meaning that they take advantage of a wide variety of different food sources, including inadvertent consumption of plastic. In addition to occupying space in the individuals’ …
