here is a serious dispute on the existence of β-N-methylamino-
L-alanine (BMAA) in water, which is a neurotoxin that may
cause amyotrophic lateral sclerosis/Parkinson’s disease (ALS/
PDC) and Alzheimer’ disease. It is believed that a reliable and
sensitive analytical method for the determination of BMAA is
urgently required to resolve this dispute. In the present study, the
solid phase extraction (SPE) procedure and the analytical method
for dissolvedBMAA inwater were investigated and optimized. The
results showed both derivatized and underivatized methods were
qualified for the measurement of BMAA and its isomer in natural
water; limit of detection and the precision of the two methods
were comparable. Cartridge characteristics and SPE conditions
could greatly affect the SPE performance, and the competition
of natural organic matter is the primary factor causing the low
recovery of BMAA, which reduced from approximately 90% in
pure water to 38.11% in natural water. The optimized SPE method
for BMAA was a combination of rinsed SPE cartridges, controlled
loading, elution rates and elution solution evaporation at 55°C,
reconstitution of a solutionmixture and filtration by polyvinylidene
fluoride membrane. This optimized method achieved > 88%
recovery of BMAA in both algal solution and river water. The
developed method can provide an efficient way to evaluate the
actual concentration levels of BMAA in actual water environments
and drinking water systems.
