DISTRIBUSI LOGAM TIMBAL (Pb) PADA TANAMAN WEDELIA (Wedelia trilobata (L.) Hitch) AKIBAT EMISI KENDARAAN BERMOTOR DI BEBERAPA JALAN KOTA SAMARINDA
Abstrak: The research has done
of "The distribution of lead (Pb) on wedelia plants contaminated by
vehicular emission on several main road in samarinda”. This study aimed to
determine the metal concentrations of lead in roots, flowers and leaves of
plants wedelia at several locations in the city of Samarinda on PM Noor Street,
Wahid Hasyim Street, Pahlawan Street, AW Syahrani Street, and Belatuk Street
(control location) were the different traffic density and the treatment of
leaching on levels of lead found in wedelia plants. The concentrations of lead
metal on wedelia plants were measured using an Atomic Absorption
Spectrophotometer (AAS) at a wavelength of 283.3 nm. The results showed that
The highest levels of Pb obtained on PM Noor and lowest on Belatuk, were the
traffic density is high concentration of lead is absorbed more than low traffic
density. And the treatment of non-leaching and leaching concentrations obtained
difference was not significant, indicating leaching did not significantly
affect the concentration of Pb on plants.
