Health and Environments Research Centre [HERC] Laboratory

Dalhousie University, Halifax, Nova Scotia
Area(s) of Expertise

Researchers at the Health and Environments Research Centre Laboratory collaborate with other investigators and  industrial partners locally and globally, to examine the sources, fate, transport and metabolism of aerosols of health significance in human environments and ecosystems. Key considerations include the associated toxicological mechanisms and pathways of host defence, tissue injury and repair, and other systems-related responses in relation to such exposures; the identification of new clinically significant markers of environmental and occupational toxicology and pathogenesis; the estimation of the population health burden of such exposures on the health of Canadians and the global community; and the development of new environmental public health policy and community health planning tools. Our areas of expertise include toxicology, environmental and occupational health, environmental chemistry, atmospheric science, and climate change.

Our facilities are linked to the Canadian Aerosol Research Network (CARN), with the global purpose of enabling researchers, consultants, and governmental officials to conduct environmental and occupational health and atmospheric science research in accordance with the Canadian Aerosol Research Network user principles and definitions.

What the facility does

Research on aerosol science, toxicological impacts of airborne particles on human health, risk assessment of air quality on human health, research and technology development on the implications of climate change for human health and society.

Research Services

Indoor and outdoor air quality assessment, characterization of environmental contaminants in air, water and soil, characterization of fine particulate matter and aerosol composition, environmental sampling method development, worksite exposure investigations, analysis of trace metals in environmental samples and filter weighing and sample collection preparation, exposure assessment support to epidemiological and occupational hygiene studies, freely accessible information and data.We provide a repository of GEOS-Chem input files (such as emission and metfields), which can be downloaded via anonymous FTP from ftp://rain.ucis.dal.ca, and data processed from meteorological input from the Goddard Earth Observing System (GEOS) of the NASA Global Modeling and Assimilation Office and the MERRA reanalysis.

We ask users to familiarize themselves with corresponding publications and communicate with the research contact listed to ensure the most up-to-date and appropriate use of information.
