Abstract
Meningkatnya jumlah alat transportasi serta gas-gas buangan yang dikeluarkan termasuk dalam salah satu contoh dari pencemaran udara yang dapat memicu terjadinya perubahan kualitas udara, misalnya karbon monoksida, nitrogen oksida, senyawa organik dan senyawa Timbal (Pb). Timah hitam (Pb) yang terdapat pada emisi kendaraan bermotor akan mencemari udara, hewan, tanaman dan manusia. Beberapa jalanan di kota banyak ditanami tanaman peneduh yang berfungsi untuk menyerap polusi udara. Tanaman yang digunakan pada penelitian ini yaitu pohon trembesi, tanaman glodokan, tanaman angsana dan tanaman kersen. Metode pengukuran konsentrasi Timbal (Pb) dalam udara ambien di lingkungan menggunakan alat Spektofotometer Serapan Atom (SSA). Penelitian ini menggunakan metode study literature review, dimana menganalisis dari beberapa jurnal terkait pencemaran udara. Hasil penelitian dari beberapa jurnal menunjukan, nilai tertinggi kadar Pb (timbal) di udara ambien di perempatan Bangkong Kota Semarang sebesar 2,41 μg/Nm3 , hal ini menunjukkan bahwa tingkat kepadatan lalu lintas kendaraan di tempat tersebut juga tertinggi, sehingga diperlukan pemantauan logam berat Pb (timbal) di Kota Semarang secara berkala agar tidak menimbulkan dampak buruk bagi kesehatan. Diketahui juga hubungan antara konsentrasi Pb dengan jumlah kendaraan berbahan bakar bensin dapat diinterpretasikan sebagai korelasi yang sangat kuat. Partikel Timbal (Pb) yang dikeluarkan oleh asap kendaraan bermotor memiliki massa tinggal di udara selama 4-40 hari. Masa tinggal yang lama ini menyebabkan partikel Timbal disebarkan oleh angin sehingga mencapai jarak 100-1000 km dari sumbernya. Selain itu, partikel logam berat Pb yang paling tinggi terdapat pada tanaman Kersen. Pada Pb Kersen berkisar antara 22.983 – 49.641 ppm sedangkan pada Pb Angsana berkisar antara 18.835 – 48.736 ppm, karena Kersen jenis permukaan daunnya mempunyai bulu dan kasar. Sehingga partikel logam berat Pb akan menempel pada daun dan masuk ke dalam sel melalui stomata.
English Abstract
The increasing number of means of transportation and the exhaust gases released are included in one example of air pollution that can trigger changes in air quality, such as carbon monoxide, nitrogen oxides, organic compounds and lead compounds (Pb). Lead (Pb) contained in motor vehicle emissions will pollute the air, animals, plants and humans. Some streets in the city are planted with shade plants that function to absorb air pollution. The plants used in this study were trembesi trees, glodokan plants, Angsana plants and cherry trees. The method of measuring the concentration of Lead (Pb) in the ambient air in the environment uses an Atomic Absorption Spectrophotometer (AAS). This study uses a literature review study method, which analyzes several journals related to air pollution. The results of research from several journals show that the highest value of Pb (lead) levels in ambient air at the Bangkong intersection, Semarang City is 2.41 μg/Nm3, this indicates that the level of vehicle traffic density in that place is also the highest, so heavy metal monitoring is needed. Pb (lead) in the city of Semarang on a regular basis so as not to cause adverse effects on health. It is also known that the relationship between Pb concentration and the number of gasoline-fueled vehicles can be interpreted as a very strong correlation. Lead (Pb) particles emitted by motor vehicle fumes have a mass of staying in the air for 4-40 days. This long residence time causes the Lead particles to be dispersed by the wind so that they reach a distance of 100-1000 km from the source. In addition, the highest Pb heavy metal particles were found in the Kersen plant. Pb Kersen ranged from 22,983 - 49,641 ppm while in Pb Angsana ranged from 18,835 - 48,736 ppm, because Kersen leaf surface type had hairy and rough. So that Pb heavy metal particles will stick to the leaves and enter the cells through the stomata.
