Abstract


The form of pollution due to industrial waste disposal mainly contains heavy metal groups. Unlike ordinary metals, heavy metals usually cause special effects on living things. This research is descriptive research with observational approach, that is a research conducted to describe a phenomenon that happened in society.
The results show that Pb heavy metal pollution in the three sampling stations and on each sample type varies. For Pb collectors at each sampling station have not exceeded the NAV of <0.01 μ / l, 0.07 μ / l and <0.01μ / l, respectively. In the shell samples have not passed the NAB of 0.12 μ / l, 0.18 μ / l and 0.11μ / l, respectively. NAB for marine biota is 0.3 μ / l. Similarly, the Pb content of the first and second station sediment samples has not passed the NAV RNO of: 0.48 μ / l, 0.61 μ / l. while at the station furthest from pantaqi (station 3) the content of Pb in the sediment sample is only 0.27 μ / l, not yet passing the NAB. This study shows that the Pb content of each sample tends to be higher in sampling 2. This occurs because at station 2 there is one river mouth but actually this estuary comes from two rivers. In conclusion, another factor causing high levels of Pb in station 2 samples because the Yotefa Bay pollution factor comes from these two rivers is visible from the soil kountur and the level of population activity in the area. The effect of pollution is also evident from the farther the sampling station will have the Plumbum content on the sample. At station 3, the station farthest from the coast shows the lowest plumbum content of all samples.
