Prediction of Damage Cost of Bronchitis Due to Haze in Malaysia

Awareness of haze pollution and management increased in Southeast Asia since 1990. However, the focus on environmental management is decreasing especially in Malaysia due to the abundant resources and increased development pressure. The total health damage cost because of haze in the country became significantly high due to the long duration of haze events year by year. This paper discusses the health damage caused by bronchitis due to the haze events in Malaysia. The analysis shows positive coefficient of independent variables which indicates the positive relationship between dependent variable and independent variables. Multiple linear regression analysis shows that 45.3% variation in damage cost of bronchitis could be explained by FAI, GDPPC, and CO2. Keywords: Health damage cost; environmental management; haze; Malaysia; prediction

Impact of Malaysia major flood to river geomorphology changes and total suspended solid using GIS technique

Flood is the most common type of disaster in Peninsular Malaysia. In December 2014, a major flood event occurred in Pahang River that recorded the worst flood ever hit Pahang River Basin and Malaysia generally. Twelve sampling station has been chosen which covered of upstream, middle stream and downstream parts of Pahang River. This study focuses on scrutinizing the processes of the river geomorphology changes using geographic information system and other techniques. Those stations are Jerantut Feri, JPS Tembeling, Chenor and Pekan. The 3D modelling surface showed that the bathymetric shape of Pahang River bed was severely affected by the flood due to collapse of river banks, land use changes and anthropogenic activities. However, other stations are also affected by the flood but it is not significant according to cluster group constructed. Total suspended solid was classified into three group using cluster analysis. The contributors of sedimentation problems in Pahang River are from unsustainable land use such as urbanization, agricultural activities, industrialization which are trapping the bed sediments and river band erosion caused by flood phenomenon. Sinuosity index (SI) of Pahang River shows that high percentage of changes occurred in the upstream at Tembeling River and Jelai River with the highest percentage recorded at 45%. SI recorded at middle stream shows a significant change with the percentage of 20.7%. While at downstream, the SI recorded three significant changes from 16.0% to 20.3%. Based on statistical analysis, significant changes with moderate correlation in R squared value at R2 = 0.6669 was obtained between SI changes and water level that occurred from 2010 to 2015. Pahang River geomorphology change analysis and river bed geometric analysis are very important in order to decide the best mitigating measure and management plan that will overcome the biggest problem of Pahang River, that is, flood – that occurs every year. Generally, this study is very important to gather information on the effect of 2014 major flood in Pahang River in order to manage the Basin of Tropical River. In future, for mitigation measure, alternative management is proposed for Pahang River Maintenance such as service of natural flood ponds and flood mitigation projects

The potential impacts of anthropogenic and climate changes factors on surface water ecosystem deterioration at Kenyir Lake, Malaysia

Water ecosystem deterioration can be affected by various factors of either natural environment or physical changes in the river basin. Data observation were made during dry season (April 2017) and wet season (December 2017). 21 sampling stations were selected along Kenyir Lake Basin. Overall, the water quality status as stated in NWQS is categorized as Class I on dry season and Class II on wet sea-son. The major pollutants in Kenyir Lake are Total Suspended Solids (TSS), Chemical Oxygen Demand (COD), Dissolve Oxygen and pH which are contributed largely by untreated or partially treated sewage from tourism development and construction activities around the basin. The sedimentation problem level in the Kenyir Lake Basin is not in critically stage but the flow rate of water and land use ac-tivities (development around basin) will be contributed to the increasing levels of sedimentation. The good site management such as the implementation of proper site practice measures to control and treat run-off prior to discharge will ensure that the construction works will not affect the quality and quantity of the receiving waters or have significant impact upon the receiving waters

Potential of field turbidity measurements for computation of total suspended solid in Tasik Kenyir, Terengganu, Malaysia

The urbanization has significant effects on watershed hydrology and the quality of water in this catchment. One component of water quality is total suspended solids (TSS) which a significant part of physical and degradation and a good indicator of other pollutants on the surface of sediment in suspension. The purpose of this study is to investigate whether turbidity could produce a satisfactory estimate of TSS in urbanizing at the Tasik Kenyir. TSS and Turbidity were analyzed based on in-situ and ex-situ analyses were carried out according to the correlation matrix and linear regression methods at 14 (10-140 m) different depths for two sampling locations in the Tasik Kenyir (which are Chomor River and Mahadir Island- the name of sampling location in Tasik Kenyir), using data compiled. A log-linear model showed a strong positive correlation between TSS and Turbidity with is (R-2 = 0.991 for Chomor River and R-2 = 0.995 for Mahadir Island) with a regression equation of ln (TSS) = 1.32 ln (NTU) + C, with C not significantly different. From the result, water quality parameter (TSS and Turbidity) showed outlet significantly which decreased over depth caused the water quality deterioration of Tasik Kenyir development. These results strongly suggest that turbidity is a suitable monitoring parameter where water-quality conditions must be evaluate
