“…Dry atmospheric deposition flux (DF x ) can been calculated by a number of methods: (i) by collecting fine and coarse aerosols using the virtual impactor (Bergametti, 1987), (ii) from theoretical models (Dulac et al, 1989), (iii) by collecting material on surrogate surfaces (Dolske and Gatz, 1985;Baeyens et al, 1990) and (iv) by subtracting wet deposition from the total deposition (Migon et al, 1997). There have been very few studies over the last decade that have attempted to estimate the dry deposition of metals in the Mediterranean Sea: in the western Basin by Guieu et al (1997) and Chester et al (1999) and in the eastern Basin only one has been reported by Muezzinoglu and Cizmecioglu (2006) at an urban site for a series of heavy metals based on a 9 month sampling period.…”

The chemical composition of precipitation in the city of Mersin on the Mediterranean coast of Turkey has been studied. Spatial and temporal variability of rainwater constituents have been determined from samples collected at two central and two suburban stations for the December 2003-May 2005 period. A total of 246 samples covering all precipitation events were analyzed to determine pH, conductivity, as well as major anion (Cl − , NO À 3 , SO 2À 4 ); major cation (H + , Na + , K + , Ca 2+ , Mg 2+ , NH þ 4 ) and formaldehyde (HCHO) concentrations. The pH varied within a range of 4.8-8.5, with only 8 out of 246 samples being acidic (pH<5.6), and the remaining highly alkaline samples being neutralized by either NH þ 4 in rainwater, or by CaCO 3 resulting from wet deposition of atmospheric dust. The volume weighted mean ΣAnion/ΣCation ratio was 0.49. The equivalent concentration of major ionic species followed the order:Formaldehyde concentrations varied in the range of 0.01-17.9 μM, and was found to be dependent on precipitation volume. Relatively higher NH þ 4 , SO 2À 4 , NO À 3 and HCHO concentrations, mainly of anthropogenic origin, measured near the city center suggest increased pollution from local anthropogenic sources, e.g., residential heating, industrial and/or traffic emissions. In general, the results of this study suggest local precipitation chemistry is more strongly influenced by natural (mineral dust and marine) sources compared to anthropogenic ones.

“…This ultimate WAD flux might be applied as a constant uniform load deposited from the atmosphere over the coastal water in these region for a eutrophication modelling study to understand their impact on water quality (Sundarambal et al, 2010). Baeyens et al (1990) described a method which allows estimation of the annual wet deposition flux of dissolved ions without measuring all rain events. When one rain event was sampled in several steps (sequential sampling), a nice, smooth dilution profile was obtained (Xianren and and the concentration decreased gradually with the volume of rainfall.…”

Impact of biomass burning on ocean water quality in Southeast Asia through atmospheric deposition: field observations

et al. 2010

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<sup>2</sup>/day) of total nitrogen (TN) were 12.72 ± 2.12 and 2.49 ± 1.29 during non-hazy days and 132.86 ± 38.39 and 29.43 ± 10.75 during hazy days; the uncertainty estimates are represented as 1 standard deviation (1σ) here and throughout the text. The estimated mean dry and wet deposition fluxes (mg/m<sup>2</sup>/day) of total phosphorous (TP) were 0.82 ± 0.23 and 0.13 ± 0.03 for non-hazy days and 7.89 ± 0.80 and 1.56 ± 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
