Abstract

Some studies have shown that levels of Pb in the groundwater around the highway positive containing Pb. This study aims to determine the ability of mustard ( Brassica juncea ) reduce levels of lead in the soil. This research uses experimental pre and post design. The object of this study is Pb in soils with mustard planting treatment to reduce levels of Pb. Implementation research held by making a planting medium that has been contaminated with Pb (NO3) 2. Then in the planting medium mustard planted as many as 10 polybag s for a month. Statistical analysis was performed using the t test statistical test to see any significant difference before and seudah Pb planted with mustard. The results showed behwa Brassica juncea has the ability to reduce levels of lead in the growing media in the range of 9.8 to 13.3%. Of the statistical tests can be concluded that mustard ( Brassica juncea ) plants have the ability to significantly reduce levels of Pb contained in the soil.

Highlights

The use of premium fuel is increasing from time to time
Elevated levels of lead in the soil affects the levels of lead in ground water consumed by the people, which in turn can accumulate in organs
Results of testing Pb content in the growing media after planted with Brassica juncea can be seen in Table 2 below: Table 2

Summary

Introduction

The use of premium fuel is increasing from time to time. Such improvements lead to increased Pb deposits in the ground along the highway in both urban and rural areas. Some research has been done indicating the that the levels of lead in ground water is already quite high. Research conducted by Athena, et al in the Greater Jakarta region showed the range levels of lead in ground water between. This figure is quite high because of the levels of lead in raw water required is 0.03 mg / l. The high Pb in ground water can come from natural sources and man-made sources. Artificial sources derived from premium fuels containing Pb
