Item Embargo Bioaccumulation of zinc in edible tropical vegetables in Peninsular Malaysia and its human health risk assessment based on various ethnicities in Malaysia(Springer, 2021) Koe Wei Wong; Chee Kong Yap; Aziran Yaacob; Rosimah Nulit; Hishamuddin Omar; Ahmad Zaharin Aris; Moslem Sharifinia; Alireza Riyahi Bakhtiari; Salman Abdo Al-Shami; Muhammad Saleem; Hideo OkamuraAlong with the growing utilization of zinc (Zn) and Zn-containing nanoparticles in various industries, Zn ecotoxicological evaluation on human food supply is necessary even though Zn is generally considered safe and rarely concentrated ecotoxicologically. This study aimed to investigate the bioaccumulation of Zn in 18 species of vegetables (seven leafy, nine fruity vegetables and one species each of tuber and legume) collected from two farming sites in the west coast of Peninsular Malaysia. A human health risk assessment (HHRA) was also conducted.Item Restricted Fluctuating Asymmetry of Chironomus spp. (Diptera: Chironomidae) Larvae in Association with Water Quality and Metal Pollution in Permatang Rawa River in the Juru River Basin, Penang, Malaysia(Springer, 2010) Salman Abdo Al-Shami; Mad Rawi Che Salmah; Ahmad Abu Hassan; Mohd Nor Siti AzizahThe levels of fluctuating asymmetry in the fourth instar of Chironomus spp. larvae inhabiting an agrochemical polluted river, Permatang Rawa River (PRR) in the Juru River Basin, northeastern peninsular Malaysia, were measured. The PRR receives waters primarily from adjacent rice fields which are exposed to fertilizer and pesticide residues. Samples of larvae, water, and sediments were collected monthly from November 2007 to June 2008. In situ measurements of water pH and dissolved oxygen were made at three sampling locations along the river. Monthly water and benthic sediment collections were also conducted for the following laboratory water analyses: biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), and ammonium-N content. Non-residual metals in the sediment samples were also analyzed. The water quality index (WQI) of the PRR was also calculated.
