Abstract

Pencemaran timbal merupakan masalah yang cukup serius karena
penyebarannya yang luas dari hasil aktivitas perumahan, pertanian dan industri. Timbal merupakan logam berat yang dapat menyebabkan berbagai masalah bagi kesehatan karena toksisitasnya yang tinggi. Tingkat pencemaran timbal yang
tinggi perlu diatasi untuk mengurangi dampak dari risiko toksisitas timbal, salah satunya dengan fitoremediasi.
Kemampuan dari akar wangi dan bunga matahari dalam proses
fitoremediasi timbal telah dilaporkan oleh berbagai literatur. Sebanyak 40 literatur digunakan sebagai sumber data. Pengkajian literatur dengan cara membuat identifikasi dan klasifikasi berdasarkan variabel dan parameter yang akan
direview dari beberapa artikel yang membahas topik yang sama menggunakan matriks sintesis.
Kedua tumbuhan memiliki sifat hiperakumulator dalam menyerap logam berat. Akumulasi logam Pb tertinggi berada di bagian akar hingga 5500 mg kg-1, sedangkan bunga matahari mengakumulasi logam Pb hingga 1450 mg kg-1. Akumulasi logam Pb pada dipengaruhi oleh tipe tanah, kelimpahan nutrisi,
rhizobakteria dan zat pengkelat. Toksisitas logam yang sangat terkontaminasi tidak mempengaruhi pertumbuhan akar wangi secara signifikan tetapi hanya terjadi sedikit penurunan parameter. Respon bunga matahari terhadap stres yang disebabkan oleh Pb bervariasi tergantung varietas, jenis tanah, jenis logam, dosis, dan durasi paparan logam.

Lead pollution is a serious problem because of its wide distribution as a result of residential, agricultural and industrial activities. Lead is a heavy metal that can cause various health problems due to its high toxicity. The high level of lead pollution needs to be overcome to reduce the impact of the risk of lead toxicity, one of which is phytoremediation.
The ability of vetiver and sunflower in the phytoremediation process of lead has been reported by various literatures. 40 literatures were used as data sources. Literature review by making identification and classification based on the
variables and parameters that will be reviewed from several articles that discuss the same topic using a synthetic matrix.
Both plants have hyperaccumulator properties in absorbing heavy metals. The highest accumulation of Pb was in the roots up to 5500 mg kg-1, while sunflowers accumulated Pb up to 1450 mg kg-1. The accumulation of Pb was influenced by soil type, nutrient abundance, rhizobacteria and chelating agents. The toxicity of highly contaminated metals did not significantly affect the growth of vetiver but only slightly decreased parameters. Sunflower response to stress caused by Pb varies depending on variety, soil type, metal type, dose, and duration of metal exposure.
