Abstract
This article reports an effect of illegal gold maining activities to the waters´ Qualities and metal on Baung fish (Hemibagrus Nemurus C.V) in kuantan rivers´ conservation area at nagari Silokek and Durian Gadang, Siunjung. This research was done on July 2013. An analysis heavy metal on fish body was done in Bung hatta university´ laboratorium which compare heavy metals´ containing with waters´ Qualities based on PP. RI No 82 . 2001 about waters´ Qualities mantainance and controling water contamination on III level. In addition, containing of heavy metals on fish body compare to the maximum of containing heavy metals on fish body based on PP. RI .No 82 . 2001 about maximum limit of metal contamination on pangans´ production. This research was measure a containing heavy metals such as : Cu, Zn, Pb and Hg on water and Baung fish on three station on july 2013. Research or observation shows containing heavy metals Cu on water in station I (1,223±0,572 mg/l), on station 2 (1,086±0,016 mg/l), on station 3 (0,803±0,052 mg/l), containing Zn on water at station 1 (0,659±0,016 mg/l) on station 2 (0,361±0,643 mg/l) on station 3 (0,503±0,136 mg/l), containing Pb on station 1 (0,926±0,008 mg/l) on station 2 (0,485±0,043 mg/l) on station 3 (0,591±0,061 mg/l), containong Hg on station 1 (0,108±0,002 mg/l) on station 2 (0,092±0,014 mg/l) on station 3 (0,022±0,003 mg/l). Containing heavy metals Cu on baung fish on station 1 (26,310±0,014 mg/kg) on station 2 (17,495±0,629 mg/kg) on station 3 (9,830±0,017 mg/kg), containing Zn on station 1 (126,155±17,573 mg/kg) station 2 (107,820±4,780 mg/kg) station 3 (77,150±8,838 mg/kg), containing Pb on station 1 (2,046±0,014 mg/kg) on station 2 (1,136±0,033 mg/kg) station 3 (0,722±0,009 mg/kg) and containing Hg on station 1 (0,700±0,067 mg/kg) on station 2 (0,271±0,0012 mg/kg) on station 3 (0,083±0,012 mg/kg). In conclusion, containing of heavy metals on each station that have been observed was over or up to maximum level of waters´ Qualities which is decided by PP. RI. No 82 .2001 about maintaining Qualities and controling water contamination.
Key word : Heavy metals, Waters’ qualities, Baung Fish.
