Coal-fired brick kilns are major contributors to the high concentration of airborne PM 2.5 within
Bangladesh and pose detrimental health risks to local communities, particularly to young children. The
health threats of PM 2.5 formed during coal combustion in brick kilns are determined by their chemical
and structural properties, which are largely unknown. The proposed project aims to (1) determine the
metal content of PM 2.5; (2) quantitatively identify PM 2.5 particle chemical and structural properties;
and (3) assess the health risks associated with toxic metals in the fine PM 2.5. Samples have been collected
from feed materials and coal-fired exhaust of brick kilns in Bangladesh. We will interrogate the particles
using advanced techniques, including transmission electron microscopy (TEM). The results of this project
will advance our understanding of the health impacts imposed by brick kilns distributed throughout
Bangladesh, and they will inform targeted policies and interventions for mitigating the health risks to local
communities.
List of Research Assistant Responsibilities:
- Sample preparation, including drying, crushing, and sieving
- Perform bulk characteristic measurements, including XRF and XRD
- Conduct brick kiln simulated heating experiments using coal samples in a muffle furnace
- Prepare samples for TEM and ICP-MS analysis
- Review and analyze data
Qualification Requirements: - Eligible to apply: Stanford undergraduate students in good academic standing and planning to return
to Stanford in Autumn 2024. Co-term students in graduate tuition status are ineligible. - All majors welcome. A background in chemistry and material characterization is helpful but not
required.
Position, Time Commitment: - Position: Fellowship for Summer Quarter through King Center for Global Development.
- Commitment: 40 hours per week in Summer.
