World's Best Scientists 2026 revealed!

Overview

D. C. Mahan was affiliated with The Ohio State University in the United States. Their research primarily focused on the environmental sciences, with key contributions in the areas of environmental chemistry, water science and technology, and health, toxicology, and mutagenesis.

Their published work covered several critical topics related to environmental contamination and health risks. The main topics of their research included:

  • Arsenic contamination and mitigation
  • Water quality and pollution assessment
  • Heavy metal exposure and toxicity

Mahan's research output includes a notable paper titled "Carcinogenic and non-carcinogenic health risks of arsenic exposure in drinking water in the rural environment," published in 2020 in the DOAJ (Directory of Open Access Journals). This paper addressed the impacts of arsenic contamination in water sources and its associated health risks.

Their frequent co-authors included:

  • O. Waissblut
  • Dante Cáceres

Their work was disseminated mainly through the DOAJ platform, reflecting engagement with open-access publication venues. While no book publications were recorded, Mahan had a consistent research presence in their domain.

Their investigations contributed to the understanding of the environmental factors affecting water quality and the assessment of toxicological consequences of heavy metal exposure, particularly arsenic, in rural drinking water environments.
