In her most recent research, the most cited papers focused on:

  • Ecology
  • Bacteria
  • Botany

Nora F.Y. Tam mainly investigates Environmental chemistry, Mangrove, Polybrominated diphenyl ethers, Contamination and Botany. Her Environmental chemistry research is multidisciplinary, incorporating elements of Rhizosphere, Environmental engineering, Sewage treatment and Pyrene. Her work investigates the relationship between Sewage treatment and topics such as Wastewater that intersect with problems in Nutrient, Scenedesmus and Parachlorella.

The Mangrove study combines topics in areas such as Bromine, HEXA, Phytoremediation, Pollution and Wetland. Nora F.Y. Tam studied Contamination and Bacteria that intersect with Algae and Food science. Nora F.Y. Tam has researched Botany in several fields, including Sonneratia caseolaris, Extraction and Horticulture.
