<abstract>
<p>Atmospheric nutrients have recently gained considerable attention as a
significant additional source of new nitrogen (N) and phosphorus (P) loading
to the ocean. The effect of atmospheric macro nutrients on marine
productivity depends on the biological availability of both inorganic and
organic N and P forms. During October 2006, the regional smoke haze episodes
in Southeast Asia (SEA) that resulted from uncontrolled forest and peat
fires in Sumatra and Borneo blanketed large parts of the region. In this
work, we determined the chemical composition of nutrients in aerosols and
rainwater during hazy and non-hazy days to assess their impacts on aquatic
ecosystem in SEA for the first time. We compared atmospheric dry and wet
deposition of N and P species in aerosol and rainwater in Singapore between
hazy and non-hazy days. Air mass back trajectories showed that large-scale
forest and peat fires in Sumatra and Kalimantan were a significant source of
atmospheric nutrients to aquatic environments in Singapore and SEA region on
hazy days. It was observed that the average concentrations of nutrients
increased approximately by a factor of 3 to 8 on hazy days when compared
with non-hazy days. The estimated mean dry and wet atmospheric fluxes
(mg/m&lt;sup&gt;2&lt;/sup&gt;/day) of total nitrogen (TN) were 12.72 &amp;plusmn; 2.12 and
2.49 &amp;plusmn; 1.29 during non-hazy days and 132.86 &amp;plusmn; 38.39 and 29.43 &amp;plusmn; 10.75
during hazy days; the uncertainty estimates are represented as 1 standard
deviation (1&amp;sigma;) here and throughout the text. The estimated mean dry
and wet deposition fluxes (mg/m&lt;sup&gt;2&lt;/sup&gt;/day) of total phosphorous (TP) were
0.82 &amp;plusmn; 0.23 and 0.13 &amp;plusmn; 0.03 for non-hazy days and 7.89 &amp;plusmn; 0.80
and 1.56 &amp;plusmn; 0.65 for hazy days. The occurrences of higher concentrations
of nutrients from atmospheric deposition during smoke haze episodes may have
adverse consequences on receiving aquatic ecosystems with cascading impacts
on water quality.</p>
