Low- and high-temperature magnetic propterites of iron-bearing particles of combustion origin

Abstract

Magnetic particulates are often observed in the forms of spherules and aggregates derived from iron impurities in fossil fuels upon combustion. Recently, magnetic properties of various atmospheric samples gather a scientific interest as economic and rapid proxies in the pollution studies based on their strong linkage to heavy metals and/or volatile organic carbons. Here we present low- and high-temperature magnetic properties of iron-bearing spherules and aggregates separated from the dry-deposit of aerosols and vehicle exhaust emission, respectively.a scientific interest as economic and rapid proxies in the pollution studies based on their strong linkage to heavy metals and/or volatile organic carbons.
