Abstract Sulfate (SO 4 2-) aerosol imparts numerous influences on the atmosphere, climate
and earth. However, current models generally fail to accurately predict sulfate production …

This study is focused on the identification of pollutant sources on black crust (BC) samples
from the Monumental Cemetery of Milan (Italy), through a multi-analytical approach based …

Sulfur isotope mass-independent fractionation signatures (S-MIF) have been widely found in
modern sulfate aerosols. Their mechanistic origins and potential implications for …

The observation of mass-independent sulfur isotope fractionations (S-MIF) in Archean–
Paleoproterozoic rocks has been instrumental in constraining oxygen levels on early Earth …

The mechanism of sulfate formation during winter haze events in North China remains
largely elusive. In this study, the multiple sulfur isotopic composition of sulfate in different …

This study presents the results of the examination and characterisation of the wall paintings
that decorate the rupestrian church named Grotta del Crocifisso, which is located in the …

In Beijing area, the precious stone objects often suffer from the black crusts on the specific
parts of the objects, in order to understand the forming mechanism of the black crusts …

Gaseous emissions and particulate matter in different aerodynamic diameters can be
derived from many sources, such as volcanic activities. According to previous studies …

The degradation of historical buildings surfaces through the formation of black crusts is a
process mainly related to air pollution. The origin of air pollutants can be determined by …
