Publication Embargo Effect of pollution on diversity of marine gastropods and its role in trophic structure at Nasese Shore, Suva, Fiji Islands(Elsevier, 2017-06-01) Suratissa, D. M; Rathnayaka, U. SOcean supplies a significant amount of food to human population. However, marine ecosystem is under a threat due to the increasing marine pollution. Fiji Islands, located in South Pacific sea, are experiencing such a threat. Therefore, this study aims to determine the effects of pollution on the diversity of marine gastropods in Nasese Shore, Suva, Fiji Islands. A detailed opportunistic survey was conducted; 85 species of marine gastropods molluscas were recorded belonging to 29 families in four different habitats (Habitat 1, Habitat 2, Habitat 3 and Habitat 4) at Nasese Shore during April–September 2014. Compared with Habitat 4, all three other habitats were polluted by frequently added sewages and domestic effluents via artificial and natural creeks to the coastal area. Therefore, diversity and abundance of the gastropods were significantly lower in those three habitats. Furthermore, a higher human consumption rate for some of the gastropods was observed.Publication Open Access Impact of urbanization on the water resources and public health in Pathumthani Province, Thailand(2006-11-22) Perera, R; Pradhan, PThis study attempts to analyze and describe the trend and pattern of urbanization, its impact on water resources as well as public health in Pathumthani province, which is an adjacent province of Bangkok Metropolitan. This province has good canal (khlong) network system. These khlongs have their own cultural and historical values. But the province has been promoted as a location for industrial development policy reforms introduced in Thailand in 1977. The study was carried out, using GIS as a tool, to identify the land use change. Major chemical parameters were selected to analysis water quality and cases registered data on water born diseases were analyzed to identify the impact on public health. The study reveals that growths have mainly occurred along the highways, river and khlongs sections. The findings highlight the situation of water quality in river and khlongs arising out of the process of urbanization in the province and its affect on public health.
