This document presents a research proposal to compare heavy metal concentrations in brand and non-brand cow milk samples in Savar, Bangladesh and analyze potential human health risks. The study will validate testing methods to select the most suitable for analyzing milk samples. Heavy metal concentrations will be measured and daily intake, hazard quotients, and carcinogenic risks will be calculated. The study aims to contribute new insights compared to previous work by directly comparing brand and non-brand milk and validating testing methods. Data collection and analysis will occur from December 2014 to November 2015. The researcher expresses gratitude to supervisors who are guiding the study.
