“…SO 2 from shipping and biogenic sulfur compounds such as dimethyl sulfide (DMS), dimethyl disulfide (DMDS), COS, H 2 S, CS 2 and CH 3 SH from ocean surfaces were not considered in the study. The contribution of emission fluxes of those species to concentrations and depositions of SO 2 and sulfate over the region could be much smaller compared to anthropogenic SO 2 from China and that from Miyakejima volcano (Streets et al, 2003;Kajino et al, 2004). However, those can be a reason for the discrepancy between the simulation and the observation because the observation sites we selected are located at isolated islands or capes, surrounded by ocean.…”

“…Because the Asian region is one of the most serious emission source regions of atmospheric pollutants in the world, there have been various studies for the estimation of its emission inventory. For recent years, Streets et al (2003), for the base year 2000, Ohara et al (2007), for up to Zhang et al (2009), for the base year 2006, have frequently been used and widely credited. The estimated Chinese emission from our emission inventory was 20.7 Tg SO 2 , which is comparable to Streets' inventory (20.4 Tg SO 2 ) and relatively smaller than the newer estimates from Ohara's inventory (27.6 Tg SO 2 ) and Zhang's inventory (22.9 Tg SO 2 for 2001).…”

“…The high uncertainty in the heterogeneous oxidation and wet scavenging processes contribute to either an increase or a decrease in particulate nss-SO 2− 4 concentrations. Heterogeneous nss-SO 2− 4 production on sea-salt (Chameides and Stelson, 1992) and dust (Tang et al, 2004) particles should promote the oxidation of sulfur, but these processes are missing in the model. As we focused on SRR of sulfur among the three Northeast Asian countries, the contributions of boundary conditions, which were not seriously taken into account, could be a reason for the underestimation of the modeled nss-SO 2− 4 .…”

“…The East Asian region has been one of the largest emission source regions in the world (Streets et al, 2003;Ohara et al, 2007;Zhang et al, 2009). Since SO 2 emitted from anthropogenic sources and volcanic eruptions is oxidized in the atmosphere during long-range transport and forms SO 2− 4 , which causes acidification of soil, land, water, and vegetation, the issue of transboundary air pollution evokes significant scientific interest and political concern (Carmichael et al, 2002).…”

“…The SRR over the ocean was poorly addressed in the previous studies but informative for the budget study. Showing SRR over the ocean is especially important for persistent and bioaccumulate hazardous materials such as polycyclic aromatic hydrocarbons (PAHs), having acute and chronic toxicity to marine life (Livingstone, 1998;Hylland, 2006;Suzuki et al, 2009).…”

Abstract. The spatial distribution of the source-receptor relationship (SRR) of sulfur over Northeast Asia was examined using a chemical transport model (RAQM) off-line coupled with a meteorological model (MM5). The simulation was conducted for the entire year of 2002. The results were evaluated using monitoring data for six remote stations of the Acid Deposition Monitoring Network in East Asia (EANET). The modeled SO 2 and O 3 concentrations agreed well with the observations quantitatively. The modeled aerosol and wet deposition fluxes of SO 2− 4 were underestimated by 30 % and 50 %, respectively. The domain was divided into 5 source-receptor regions: (I) North China; (II) Central China; (III) South China; (IV) South Korea; and (V) Japan. The sulfur deposition in each receptor region amounted to about 50-75 % of the emissions from the same region. The largest contribution to the deposition in each region was originated from the same region, accounting for 53-84 %. The second largest contribution was due to Region II, supplying 14-43 %. The spatial distributions of the SRRs revealed that subregional values varied by about two times more than regional averages due to nonuniformity across the deposition fields. Examining the spatial distributions of the deposition fields was important for identifying subregional areas where the deposition was highest within a receptor region. The horizontal distribution changed substantially according to season.

Fish scale culture can be used as a model to test the effects of several molecules on bone metabolism by histological and biochemical methods, although solid cell biology data about the behavior of the scale cells in culture are needed if such a model is to be employed for pharmacological applications. In the present study, we cultured zebrafish scales at various temperatures and for various times and analyzed the behavior of the bone cells in terms of viability and activity. We demonstrated that the cultured scale cells maintained their usual distribution at 28°C until 72 h, after which time episquamal osteoblasts showed an obvious change in their cell organization followed by an increase in cell death. Osteoclast tartrate-resistant acid phosphatase and osteoblast alkaline phosphatase activities were maintained until 72 h but were reduced at 96 h as a consequence of the massive cell death. This scenario indicates that zebrafish scales cultured until 72 h can be considered as an innovative model of explanted organ culture to assay the ability of chemical compounds to modulate the metabolism of bone cells.
