Assessing Trace Metal-Based Human Health Risks for Commonly Used Body Soaps in Bangladesh

Area of Science:

• Environmental Science
• Consumer Product Safety

Background:

• Body soaps are widely used in Bangladesh, valued for flavor and low alkali content.
• Assessing trace metal contamination in consumer products is crucial for public health.

Purpose of the Study:

• To quantify trace metal contamination in commonly used body soaps in Bangladesh.
• To evaluate potential health risks associated with dermal exposure to these trace metals.

Main Methods:

• Analysis of trace metals (Fe, Cu, Zn, Cr, Mn, Ni, Cd, Pb) in 21 body soap samples.
• Comparison of detected concentrations with World Health Organization (WHO) permissible limits.
• Health risk assessment using Chronic Daily Intake (CDI) and Hazard Quotient (HQ) calculations.

Main Results:

• Iron, copper, zinc, manganese, and nickel were within WHO limits; cadmium and lead were below detection limits.
• Chromium levels exceeded WHO limits in two out of 21 samples.
• No non-carcinogenic or carcinogenic health risks were identified from the use of these soaps.

Conclusions:

• While most body soaps in Bangladesh show acceptable trace metal levels, elevated chromium in some samples warrants attention.
• Current usage patterns do not indicate significant health risks, but continuous monitoring of trace metals in beauty soaps is recommended.
• This study establishes baseline data on trace metal contamination in Bangladeshi body soaps, highlighting the need for ongoing safety assessments.
