Use of pressurized hot water extraction and high performance liquid chromatography-inductively coupled plasma-mass spectrometry for water soluble halides speciation in atmospheric particulate matter

► PHWE is a simple and fast extraction procedure. ► Time treatment required is 9 min. ► Extracting solution addition and filtration is automated. ► The major water-soluble Br and I species are Br− and IO3−. ► Twenty percent (total Br) and 11 percent (total I) may be soluble.
