Abstract

This study was aimed to observe the content of led substances (Pb) in Angsana,s(Pterocarpus indicus Willd) and Glodogan,s (Polyalthia longifolia Bent & Hook. F )leaves growing along the busy roads in Denpasar. The study was conducted fromNovember to December 2002. Sample were obtained from five location with busy trafficswhile another one was from un busy traffics as control. Sample were analysed at AnalyticLaboratory, Udayana University using wet digestion method, then were analysed usingAtomic Absorbance Spectrofotometer (AAS).Result showed that the lead (Pb) content in Angsana’s leave out weighed theGlodogan’s leave and Pb content on November exceeded that on December 2002. Overall,analysis of all samples, on November and December 2002, indicated that the Pb contentwas bellow the standard allowed which was 1000 ppm (?g/g)

Abstract

This research was conducted in Serangan island in August, 2004. Ten plots assampling units were taken using Systematic Plot Design. Two parameters : ImportanceValue and Diversity Indices were determined on vegetation analyses. Samples were takenfrom three different locations. Soil analysis was conducted for determining macro elementscontent, such as: N, P, K and others organic maters.The result shows that there are 13 species of mangrove found. Five species areclassified into ‘pure’ mangrove and others are associate. Rhizophora apiculata (withImportant Value, IV, of 103.252 %) and Sonneratia alba (IV 99.663 %) are two species thathave high importance value (IV). In addition, the diversity of mangrove in Serangan islandis found to be low (diversity indices 0.791).Results of this study indicate that after reclamation, the mangrove ecosystem inSerangan is in unstable conditions.

Seawater quality parameters that exceed the Environmental Quality Standards is DO, BOD5, NO3, NH3, phenol, phosphate, cadmium (Cd) and Plumbum (Pb). The results on the quality of coastal waters are four beaches (Kuta, Legian, Nusa Dua and Jimbaran) are classified as low polluted, and two beaches (Tanjung Benoa and Canggu) is classified as middle polluted.
