A PROPER inventory of atmospheric emissions from natural sources is basic to our
understanding of the atmospheric cycle of the trace metals (and metalloids), and is also …

FEW (if any) recent studies on the atmospheric cycle of trace metals have considered the
flux of the metals into the atmosphere on a global scale. Information on worldwide emissions …

Calculated loading rates of trace metals into the three environmental compartments
demonstrate that human activities now have major impacts on the global and regional cycles …

INDUSTRIAL activity has been assumed to be largely responsible for the heavy metal
content of atmospheric particulates1. We have obtained, however, laboratory evidence that …

Particulate matter is a component of ambient air pollution that has been linked to millions of
annual premature deaths globally,–. Assessments of the chronic and acute effects of …

AEROSOLS influence the global radiation budget1, and so changes in the atmospheric
aerosol load due to either natural causes or human activity will contribute to climate …

Aerosol formation in the atmosphere is an important process to understand, in that such
particles may act as the cloud condensation nuclei responsible for the 'cloud–climate'effect …

AIRBORNE mineral dust can have a significant effect on the Earth's radiation budget, as it
can both scatter sunlight back to space (leading to negative radiative forcing), and absorb …

MAN-INDUCED changes affecting the trace metal composition of seawater through river
runoff have their initial effects in coastal regions close to the source of pollution. It is now …

DESPITE evidence from Greenland ice cores for pre-industrial atmospheric trace-metal
contamination1, 2 it is commonly assumed that air pollution in remote areas is a recent …
