Abstract
Arsenic contaminants cause a high potential risk to human health and the environment.
Exposure of humans and animals to arsenic results in a variety of toxic effects ranging from
immediate mortality to slow process of carcinogenesis. The primary goal of this proposal is to
develop molecular biomarkers for monitoring arsenic exposure in aquatic ecosystems. In addition,
the tissue distribution of arsenic and the corresponding biochemical effects in tilapia fish will be
investigated.
This 2-year grant proposal will continue the work from previous year to study arsenic induced
biochemical effects in aquatic organisms. The studies employed in this proposal will reflect the
specific toxic effect of arsenic and reveal fundamental relationships between chemical structures
and biological activity. The molecular biomarker developed in this study may serve an early
warning system for the detection and monitoring arsenic exposure in aquatic ecosystems. This
may contribute to a better accurate risk assessment.
