Heavy metals in catfish and tilapia species in ex-mining area and their potential risk to human health / Nurul Fatihah Raihan Hj Mohd Nawi
Harvesting of the aquatic organism like the fish is part of the major source of protein for human kind. Nowadays many anthropogenic activities by human as illegally and continuously without proper management can contribute to increase the amount of heavy metals in the environment, especially in aqua...

A study to determine the level of water quality and heavy metals in fish muscle from Bestari Jaya was conducted. The water from ex-tin mining area was used as the water source in the fish pond and as the breading site of fish for commercialized into the market. The physicochemical parameters measured were pH, temperature, dissolve oxygen (do), turbidity, chlorine and three metals namely tin (Sn), lead (Pb), and zinc (Zn). The contamination of heavy metals such as tin, lead, and zinc in the water and fish was quite dangerous. Eight water samples of water and sixty samples for fish were collected for analyzes.

The detection of heavy metal in the water for the Tin concentration falls in class IV as stated in Interim National Water Quality Standard for Malaysia (INWQS) 2008.

Meanwhile all heavy metals concentration in the muscle of fish exceeded the permissible limit according to MFA 1983 except Zn concentration which complied with that standard. The result shows the concentration of the heavy metal of the fish and water was in order of Sn > Zn> Pb. However the Hazard Index (HI) both of the sample showed less than 1, so there is no significant health effect of consuming both fish species from the ex - mining area on Bestari Jaya, Selangor. 2017-07 Student Project NonPeerReviewed text en http://ir.uitm.edu.my/id/eprint/45822/1/45822.pdf ID45822 Hj Mohd Nawi, Nurul Fatihah Raihan (2017) Heavy metals in catfish and tilapia species in ex-mining area and their potential risk to human health / Nurul Fatihah Raihan Hj Mohd Nawi.
