Purpose: To assess whether bisphenol A contamination occurred in seven brands of bottled drinking
water in Riyadh, Saudi Arabia.
Methods: Liquid-liquid extraction (using dichloromethane) was used to analytically extract bisphenol A
from drinking water bottles and a gas chromatograph-mass spectrometer was employed for its detection
using a splitless capillary column and helium as the carrier gas.
Results: The concentration of bisphenol A (BPA) was high in all the bottled water brands tested. The
mean concentration of BPA of the bottled water stored indoors (4.03 ng/L) was significantly lower than
that stored outdoors (7.5 ng/L).
Conclusion: Our results show that significant amounts of BPA leached from bottle containers into the
water. Long storage of bottled water under direct sunlight should be avoided to reduce the risk of human
exposure to BPA.
