PENGARUH LOGAM BERAT Cd, Pb TERHADAP PERUBAHAN WARNA BATANG DAN DAUN SAYURAN
Abstract: Cd, Pb
heavy metal absorption
in aquatic vegetables:
Genjer (Limnocharis flava), Kangkung air
(Ipomoea aquatica Forsk)
dan Selada air
(Nasturtium officinale R.
Br), studied to see
the relationship with
green figure scale.
The research objective
was to identify the accumulated
Cd, Pb in the consumed organ vegetable, and their impacts to the levels of
green figure scale.
The research was
undertaken by planting
three kinds of the
aquatic vegetables to the contaminated pure Cd,pure Pb media, mixture of Cd and
Pb with factorial randomized block
design. Data were
analyzed by factorial
One-Way Anova and further
test of Duncan
and HSD to
see the difference
of Cd, Pb
and green figure
scale, regression and correlation
to know the
contribution of Cd,
Pb in influencing
the green figure scale.
Variety of vegetables,
media, organ, and
the interaction influences
the accumulation of Cd, Pb and level of green figure scale. There is a
relationship between Cd, Pb metal accumulation
to the level
of green figure
scale of the
aquatic vegetables, with negative correlation that Cd, Pb
decreased the vegetable green figure scale.
Keywords: the influence of Cd,
Pb; aquatic vegetables; green figure scale
