This is the first publication on distribution and sources of polycyclic aromatic hydrocarbons (PAHs) in riverine coastal sediments South East Asia where rapid transfer land-based pollutants into aquatic environments by heavy rainfall runoff waters great concern. Twenty-nine Malaysian were analyzed for PAHs (3-7 rings) gas chromatography mass spectrometry. Total concentrations sediment ranged from 4 to 924 ng/g. Alkylated homologues abundant all samples. The ratio sum methylphenanthrenes...
This study provides the first investigation on occurrence of human pharmaceuticals in tropical aquatic environment Malaysia. Water samples were collected at seven different sites along Langat River and effluents from five sewage treatment plants (STPs) Basin. Samples extracted by solid phase extraction (SPE) analyzed using liquid chromatography coupled with a tandem mass spectrometry (LC-MS/MS) for 18 six therapeutic classes one metabolite. Fifteen out these 19 detected river water samples....
An investigative study was carried out in Langat River to determine the heavy metal pollution sediment with 22 sampling stations selected for collection of samples. The samples were digested and analyzed extractable ((48)Cd, (29)Cu, (30)Zn, (33)As, (82)Pb) using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Parameters, such as pH, Eh, electrical conductivity (EC), salinity, cation exchange capacity (CEC) loss on ignition (LOI) also determined. assessment derived enrichment factors...
This is the first report on fecal pollution using molecular markers in Southeast Asia where serious sewage has occurred. A simple and sensitive analytical method gas chromatography−mass spectrometry for 10 sterols various environmental samples was developed to monitor extensive areas of tropical Asia. First, applied wastewater confirm that >95% existed particulate phase. Then approach a Asian region, Malaysia Vietnam, with selection 59 sampling stations total. River water sediment were...
The Straits of Malacca is one the world's busiest supertanker routes, and tanker-derived oil spills occur frequently. In addition, domestic have been increasing due to growing industrialization Malaysia. deter mination exact source critically important. This paper examines utility biomarker compounds, triterpanes, identify spills. Middle East crude oils (MECO), South Asian (SEACO), tar-balls, sediments, mussels were analyzed. most distinctive compositional features for are that 17α,...
Mussel samples were used in this study to measure the levels of polybrominated diphenyl ethers (PBDEs) and organochlorines (OCs) coastal waters Asian countries like Cambodia, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Philippines, Vietnam. PBDEs detected all analyzed, concentrations ranged from 0.66 440 ng/g lipid wt. Apparently higher found mussels which suggests that significant sources these chemicals exist around region. With regard composition PBDE congeners, BDE-47,...
This paper determines the controlling factors that influence metals’ behavior water-sediment interaction facies and distribution of elemental content ( 75 As, 111 Cd, 59 Co, 52 Cr, 60 Ni, 208 Pb) in water sediment samples order to assess metal pollution status Langat River. A total 90 were collected simultaneously triplicate at 30 sampling stations. Selected metals analyzed using ICP-MS, concentration varied among Metal concentrations ranged between 0.08–24.71 μ g/L for <0.01–0.53...
The Jatropha curcas plant or locally known as "Pokok Jarak" has been widely used in traditional medical applications. This is to treat various conditions such arthritis, gout, jaundice, wound and inflammation. However, the nature of compounds involved not well documented. Hence, this study was conducted investigate anti-inflammatory activity different parts J. identify active involved.
