“…Recently, great development has occurred around Malaysia, especially Peninsular Malaysia as industrialization, urbanization, the advancement of agriculture and other activities related to the modern era are occurring rapidly, which have directly influenced the coastal ecosystems that contain aquatic resources, for example, fish, which are also used by humans (Kamaruzzaman and Ong, 2009). Heavy metal concentrations contained in the effluents pollute river water and contaminate fish, eventually creating significant health risks and economic costs for residents, including the polluters (Poon et al, 2016). When large quantities of pollutants are released, there may be an immediate impact as measured by large-scale sudden mortalities of aquatic organisms, e.g.…”

Purpose This study aims to examine the metal pollution in coastal sediment in the Peninsular Malaysia. Design/methodology/approach Approximately 141 published studies were screened from 1,285 documents and reviewed to determine the existing pollution status in the coastal areas of Peninsular Malaysia and the metals under review were Pb, Hg, Cd, Ar, Cu, Zn, Cr and Ni. Sources of pollutants and their effect on biological systems, marine organisms and human health were addressed in this review as well as recommendation of heavy metal removal or remedies in short. Emphasis is placed on marine pollution, particularly on the toxic metal accumulation in biota. Findings This study has revealed the different concentrations of pollutants, low, moderately, and chronically contaminated areas from heavy metals and the consequences to aquatic ecosystem and indirectly to human health, since an increasing in the coastal developments in Peninsular Malaysia. Originality/value This study has revealed the different concentrations of pollutants, low, moderately, and chronically contaminated areas from heavy metals and the consequences to aquatic ecosystem and indirectly to human health, since an increasing in the coastal developments in Peninsular Malaysia.

“…Although Po-210 status in raw ( t = 3.22, p = 0.015) and treated water ( t = 2.924, p = 0.022) was significantly safe at 95% confidence level (i.e., t statistic) through drinking water, however, the overall efficiency of all the WTPs in the basin was about 59% which might be due to an inability to remove Po-210 from treated water by the conventional method used at the plants as well as the small number of water samples. The Serai and Langat WTPs have the higher Po-210 removal efficiencies from treated water, about 93% and 81%, respectively, might be because of lower iron concentration (175 µg/L) in the upstream region of the Langat River than the downstream (264 µg/L) [ 46 ] along with higher manganese and total dissolved solids at the downstream [ 47 , 48 ], although all the WTPs in the basin follow a conventional coagulation method.…”

The presence of toxic polonium-210 (Po-210) in the environment is due to the decay of primordial uranium-238. Meanwhile, several studies have reported elevated Po-210 radioactivity in the rivers around the world due to both natural and anthropogenic factors. However, the primary source of Po-210 in Langat River, Malaysia might be the natural weathering of granite rock along with mining, agriculture and industrial activities. Hence, this is the first study to determine the Po-210 activity in the drinking water supply chain in the Langat River Basin to simultaneously predict the human health risks of Po-210 ingestion. Therefore, water samples were collected in 2015–2016 from the four stages of the water supply chain to analyze by Alpha Spectrometry. Determined Po-210 activity, along with the influence of environmental parameters such as time-series rainfall, flood incidents and water flow data (2005–2015), was well within the maximum limit for drinking water quality standard proposed by the Ministry of Health Malaysia and World Health Organization. Moreover, the annual effective dose of Po-210 ingestion via drinking water supply chain indicates an acceptable carcinogenic risk for the populations in the Langat Basin at 95% confidence level; however, the estimated annual effective dose at the basin is higher than in many countries. Although several studies assume the carcinogenic risk of Po-210 ingestion to humans for a long time even at low activity, however, there is no significant causal study which links Po-210 ingestion via drinking water and cancer risk of the human. Since the conventional coagulation method is unable to remove Po-210 entirely from the treated water, introducing a two-layer water filtration system at the basin can be useful to achieve SDG target 6.1 of achieving safe drinking water supplies well before 2030, which might also be significant for other countries.

“…Sikap komuniti seperti ini secara tidak langsung menggagalkan usaha kerajaan dalam menguruskan pencemaran sungai pada masa kini (Ismail et al, 2010). Jabatan Alam Sekitar (2017) menyatakan bahawa tingkah laku manusia yang tidak bertanggungjawab seperti melaksanakan projek pembangunan akan menyebabkan pencemaran air sungai yang mana menjejaskan sumber semula jadi seperti pengurangan jumlah ikan (Poon et al, 2016). Nayan et al (2009) menyatakan bahawa sikap masyarakat yang suka mengambil langkah mudah dengan mengalirkan sisa-sisa kumbahan dari kediaman mereka seperti air basuhan, najis dan sampah sarap terus ke dalam sungai telah menjadi penyumbang kepada berlakunya pencemaran sungai.…”

Environmental issues are not peculiar in this country, especially issues involving river pollution. River pollution will affect food sources, economic activities, health conditions, as well as many other important aspects in human life. The objective of this study is to discuss the awareness of the community in dealing with the issue of Sungai Pinang pollution by using indicators of knowledge, effect, and action. This study uses quantitative methods through a questionnaire involving 100 community respondents who live in the Sungai Pinang area. Respondents involved were randomly selected in the data collection process. Data was analyzed to obtain frequency and percentage values. The findings show that the community's dominant source knowledge on Sungai Pinang pollution is based on their own observations, while their dominant knowledge of factor contributes to Sungai Pinang pollution is the result of garbage disposal activity. Whereas, the dominant effects of Sungai Pinang pollution are foul air and dirty environment. As for their dominant action against Sungai Pinang pollution is to ensure that the doors and windows of the house are always closed and the safety net is placed in the yard. This study has the potential in providing information and understanding to the community to deal with river pollution issues. In addition, it is hoped that this study will serve as an important reference to the authorities in formulating holistic strategies and interventions for human and environment well-being.
