Professor Masaaki Kurasaki's research lab specializes in environmental toxicology and metal-microbe interactions, focusing on the impacts of heavy metals and nanomaterials on biological systems. The lab investigates the molecular mechanisms of metal toxicity—particularly mercury, silver nanoparticles, cadmium, and chromium—along with the protective roles of essential elements like selenium and metallothioneins. Research spans in vitro cellular models, water quality assessment in diverse geographical regions, and the development of sustainable materials for heavy metal remediation. The lab emphasizes both environmental risk assessment and innovative solutions for water purification and pollution control.

With the development of nanotechnology, silver nanoparticles (Ag-NPs) have become one of the most in-demand nanoparticles owing to their exponential number of uses in various sectors. The increased use of Ag-NPs-enhanced products may result in an increased level of toxicity affecting both the environment and living organisms. Several studies have used different model cell lines to exhibit the cytotoxicity of Ag-NPs, and their underlying molecular mechanisms. This review aimed to elucidate differ
Abstract To compare water quality in rivers of developed and developing countries, a study based on physicochemical parameters and dissolved metals levels was conducted. Water samples were collected from selected sites in Dhaka, Bangladesh; Hokkaido and Osaka, Japan; Erdenet, Mongolia and West Java, Indonesia. Analysis of least significant differences revealed that most water quality parameters were within comparable low levels in both developed and developing countries. The dissolved metals con
