River is a source of water for the human living that very vulnerable to the pollution for the development of industry. The heavy metal in the river exists naturally or caused by human activity. The heavy metal in aquatic environment has a negative impact for the aquatic environment and also to the human being who use and consume the water and consume the fish of the river. The estuary of Percut is a meet of sea water and the river from the upper stream carry the pollutant such as PVC, battery, oils and other ones that caused the pollution of Pb on the estuary as well as fish on the estuary include the tilapia fish (Oreochromis mossambicus)
The objective of this research is to study the content of heavy metal (Pb) that found in tilapia fish (Oreochromis mossambicus) in the estuary of Percut. This research was conducted in the estuary of Percut in Village of Percut, sub- district of Percut Sei Tuan.
This research is a descriptive study. The sample in this research is tilapia fish and estuary fish that took in 3 points, i.e. in the left side, right side and in the center of estuary. The data was analyzed descriptively in the table formulation and then narrated.
The results of research indicates that the concentration of lead in the estuary is 0.1490 mg/l up to 0.1750 mg/l indicates that this concentration is over than standard quality according to government regulation No. 82 of 2001 concerning to the Management of water quality and pollution control, i.e. 0.03 mg/l. in the tilapia fish (Oreochromis mossambicus), it only three fishes that contain lead for 0.035 mg/kg, 0.1666 mg/kg, 0.035 mg/kg, respectively and under the determined quality standard in SNI 7387 – 2009 concerning to the maximum content of heavy metal in food for lead (Pb) in fish and its processed fish, i.e. 0.3 mg/kg. This is influenced by physiology factor of fish and estuary.
The pollution and accumulation of heavy metal in the aquatic organism such as fish requires the continuous monitoring to the waste disposed into the river.

Background : This study aims to determine the level of lead in semen, measuring sperm motility,
identify the factors that influence the level of lead in semen and sperm motility, and to analyze the
relationship between sperm motility and concentration of Pb in semen, with consecutive sampling
technique sampling. Analysis of sperm motility and interviews conducted in the laboratory biology
FK. Sriwijaya University of Palembang. Meanwhile, the measurement of lead content in the semen
made in the laboratory affiliated of the Department of Chemistry, Indonesia University.
Method: In the study there were 39 respondents, consisting of 20 respondents with a motility of
sperm is not good, and 19 respondents with sperm that has good motility. Levels of Pb in semen has
less than a value range up to 266,7 µg/dl with an average of 56,69 µg/dl.
Results: Results of correlation between the motility of the level of lead in semen showing the value
of r=0,184, while the value of significance 0,262, which means that no significant relationship. T
test results, it was found that p value=0,052, which means there is no significant difference in the
average level of lead in semen among respondents who either motility with motility is not good. The
result of multiple linear regression analysis, variables associated with the number of cigarette Pb
levels in semen. The number of spermatozoa associated negatively to level of lead in semen.While
the multiple logistic regression analysis, the number of cigarette and alcohol consumption related to
the level of lead in semen. The result of multiple linear regression analysis on variables associated
with nutritional obtained motility.While the results of logistic regression analysis, variables and the
amount of cigarette smoking associated with motility.
Conclussion: The results of analysis between the motility of the level of lead in semen is not a
significant correlation between both variables. Thus considered, the highest concentration (266,7
µg/dl) is, not yet strong influence on sperm motility. So we need more research on Pb levels in a
more concrete effect on sperm motility in populations exposed to higher Pb levels. In addition, the
need also further research into the effects of total cigarette consumption on sperm motility.
