Using small brush method to collect general residents' indoor dust and using common acid decomposition method to process samples,with ammonium dihydrogen phosphate and magnesium nitrate as matrix modifier,graphite furnace atomic absorption spectrophotometric method was adopted to determine the lead in indoor dust.At the same time,quality control method such as quality control sample detection and recovery were used.It was concluded that the method's standard curve had good linearity,high recovery and good repeatability,and was suitable for the determination of lead in indoor dust.
