The purpose of this study is to provide information regarding the content, concentrations and status of heavy metals Fe and Mg on water and sediment in the waters of the Tarakan City. Materials used are samples of water and sediment samples. Analysis of heavy metals in water and sediment using Kausik (2009). the results analysis is showed the presence of heavy metals Fe and Mn in water and sediment. Fe concentration on water samples ranged 0,145-0,220 mg/L. The highest area was the River Strat Buntu 0,220 mg/L and the lowest area are Juata KORPRI 0,145 mg/L. Mg concentration on water samples ranged 4,290-0,422 mg/L. The highest was river KKMB 4,290 mgl/l and the lowest at Juata Laut 0,422 mg/L. Heavy metal Fe concentration on sediment was ranged 0,177-1.751 mg/L. The highest was on KKMB 1,751 mg/l and the lowest was Juata Sea 0,177 mg/L. Heavy metal Mg concentration on sediment samples was ranged 0,457-3.721 mg/L. Mg supreme concentration was KKMB 3,721 mg/L and the lowest at Juata Laut 0,457 mg/L. Status of heavy metal concentrations in waters are generally above the threshold quality standards required and on sediments is still below the threshold quality standards required.

Fish and invertebrate aquatic animals are very sensitive to cyanide exposure. Free concentration in the environment can reduce the ability to swim and inhibit reproduction of many species of fish. Another adverse effect is pathology, sensitivity the nature of predators, impaired respiratory system, disorders of osmoregulation and different growth patterns. The networks that depend anaerobic respiration, such as primary liver and nervous system was also affected. Fundamental changes where associated with toxin by hydrogen cyanide (HCN) is distinguished in three categories, the sensors, motor and interneuronal depends on how much damage is take. HCN may cause cell death or survival but there is damage in small sections of dendrites or axons, so that shrinkage or loss of entire functions. In fish it will lose swimming ability for a moment, and when in large doses cause of death. Keywords : Cyanide, effect on fish, sensor, motor, interneuronal

Trochus sp was gastropod which is a herbivore. Have a natural habitat in coral reefs of the Indo-Pacific waters. In addition to consumption, shell Trochus sp. has the highest economic value which caused the demand is high, and resulting the reduction in natural populations. Trochus sp including one of protected species in Vietnam. Basic information about the ecology and reproductive biology of Trochus sp can provide the knowledge to assure the survival and availability of these organisms in nature. Trochus sp plant-eating animals, and eat green plants and red algae (Cyanophycae and Phaeophycae). They also looking in benthic area for diatoms and benthic foraminifera (Asano 1944). The Natural habitat of Trochus sp in the coral reefs, usually found in the area of reef flat. Maximum density found in reef areas are facing the wind but can also be found on the coral reefs that are at lower limit of the wind, in the intertidal zone and subtidal zone in shallow water (Kitutani and Yamakawa 1999). The maximum depth of Trochus sp to growing was to 10 m, although they can also be found at a depth of 25 m (Bertram 1998). Trochus have spawning at the high tide, with external fertilization and performed at night (nocturnal spawning). According to Sims (1988), Trochus spawn approximately three to five times a year. Small Trochus can growth faster than adults. The higher of Trochus growth rate is in the dry season (March to October) compared to the rainy season (November to March).

The purpose of research is to determine the content of heavy metals Pb and Cd in river waters Tarakan City. Water sampling method are using a van Dorn water sampler and sediment samples using egmen grabs. The sample extraction method by Kaushik (2009). Sampling locations are 9 rivers is Istra Buntu, Tg. Batu, Skip kampong 1, KKHM, Karang anyar, Juata laut, Juata korpri, Binalatung dan Pasar Batu. The results show the mean Pb in the water at all stations from 0.228 to 0.181 mg/L, while the average sediment from 0.280 to 0.180 mg/L. Cd levels in water averages 0.259 to 0.226 mg/L, while the average level of Cd in sediments from 0.257 to 0.233 mg/L. Evaluation of heavy metals Pb and Cd in the water at all observation station still is above the threshold of water quality standards and the sediment is below the required quality standards.
