Abstract

Penelitian ini bertujuan untuk mengetahui jenis pohon yang ada di Jalan Sisingamangaraja kota Medan, mengetahui pengaruh jenis pohon terhadap penyerapan logam timbal (Pb), mengetahui jenis pohon yang paling efektif menyerap Logam Timbal (Pb). Penelitian ini dilakukan di Balai Laboratorium Kesehatan Medan. Populasi dan sampel dalam penelitian ini adalah seluruh jenis daun dari pohon objek penelitian. Hasil penelitian adalah terdapat 7 jenis pohon dari 7 famili yaitu Angsana (Papilionaceae), Glodokan (Annonaceae), Mahoni (Meliaceae), Mangga (Anacardiaceae), Palem raja (Aracaceae), Beringin (Moraceae), Ketapang (Combreaceae). Jenis pohon yang paling banyak jumlahnya adalah Mahoni (158 pohon) dan yang paling sedikit adalah Ketapang (2 pohon). Jenis pohon yang mempunyai kadar timbal (Pb) paling banyak adalah pohon Mahoni yaitu 1,88 μg/g. Jenis pohon yang paling efektif menyerap Logam timbal (Pb) adalah Mahoni (Meliaceae). Mahoni dijadikan sebagai pohon pelindung karena diindikasikan bahwa pohon ini berpotensi untuk menurunkan kadar timbal (Pb) di udara.
