Since　2016,　the　Ministry　of　Ecology　and　Environment　and　the　Beijing　Municipal　Government　have　adjusted　the　minimum　concentration　limit　for　ambient　air　dustfall　several　times,　indicating　that　they　attach　great　importance　to　dustfall.　To　grasp　the　pollution　characteristics　and　sources　of　dustfall,　in　this　work,　the　filtration　method　was　used　to　determine　the　insoluble　dustfall　and　water-soluble　dustfall　in　the　urban　area　of　Beijing.　From　our　analysis,　the　influence　of　the　meteorological　parameters　on　dustfall　was　found,　and　the　chemical　components　of　dustfall　were　determined.　The　positive　matrix　factorization　(PMF)　model　was　also　utilized　to　analyze　the　sources　of　dustfall.　The　results　indicated　that　the　average　amount　of　dustfall　in　2021-2022　was　4.4　t(km230　d)-1,　and　the　proportion　of　insoluble　dustfall　deposition　was　82.4%.　Dustfall　was　positively　correlated　with　the　average　wind　speed　and　temperature　and　negatively　correlated　with　the　relative　humidity　and　rain　precipitation.　The　impact　of　the　meteorological　parameters　on　insoluble　dustfall　and　water-soluble　dustfall　was　the　opposite.　The　average　proportions　of　crustal　material,　ions,　organic　matter,　element　carbon,　trace　elements,　and　unknown　components　were　48%,　16%,　14%,　1.4%,　0.20%,　and　20%,　respectively.　The　proportions　of　the　crustal　material　and　ions　were　the　highest　in　spring　(57%)　and　summer　(37%).　The　contribution　rates　of　fugitive　dust　source,　secondary　inorganic　source,　mobile　source,　coal　combustion　source,　snow　melting　agent　source,　and　other　sources　were　42.4%,　19.3%,　8.3%,　3.0%,　2.7%,　and　24.3%,　respectively.　This　study　supported　dustfall　pollution　control　by　analysing　the　pollutant　characteristics　and　sources　of　dustfall　from　the　standpoint　of　total　chemical　components.　In　order　to　better　control　dustfall　pollution,　control　measures　and　evaluation　standards　for　fugitive　dust　pollution　should　be　formulated.
