This research is aims to find out the content of heavy metals Pb on cabbage leaf and plum tomatoes in three districts of Karo Regency, those are Simpang empat, Kabanjahe and Tiga Panah district. The plant analysis have held in the laboratory of oil palm Research Centre (PPKS), at April-May 2016, using Random Design Group (RAK) factorial with three replications. The first factor is the type of plants: cabbage leaf and fruit skins of tomato, the second factor is the distance from the highway, namely the 5 m and 10 m and the third factor is the leaching that is without being washed and washed with flowing water. The parameters observed are heavy metal Pb content in the leaves of the plant and fruit skins cabbage tomato plants. The results showed that the type of plant, the distance from the highway and the leaching effect on levels of Pb. The levels of Pb on cabbage leaf at a distance of 5 m and 10 m without washing each 6.19 ppm and 4.79 ppm and with leaching 4.48 ppm and 3.86 ppm. While the levels of Pb on tomato fruit at a distance of 5 m and 10 m without leaching 4.01 ppm and 3.10 ppm and with leaching 3.08 ppm and 2.26 ppm.
