Lead (Pb) Contamination in Street Vendors Fried Foods in School Area of Padang Municipality, Indonesia.

Abstract

This study aimed to analyze the effect of transportation on lead (Pb) concentration in fried street foods of Padang school area and to analyze hygiene and sanitation handling against processed fried street foods ingredients. Samplings for the analysis of Pb concentration in fried street foods of school was conducted at the school area that located on the primary arterial road and the local secondary road in Simpang Haru District. Fried street food sampling and vehicle volume counting were conducted for 7 consecutive school days. In addition, the distribution of questionnaires to students and also to all traders of street food. The average Pb content of fried street food on primary arterial roads in the range of 0.249 -0.288 ppm and on local secondary roads ranging from 0.155 -0.218 ppm. The content of Pb in the primary arterial road passes the quality standard set by National Agency of Drug and Food Control Indonesia (0.25 ppm) and SNI (0.2 ppm). While the Pb content of the schools in the local secondary road only passed the SNI quality standard. The levels of Pb in food and volume of vehicles passing through the primary arterial road has a correlation value of 0.714, while on local secondary roads was 0.143. Pb in foods was not only caused by motor vehicle pollutants but also treatment when handling. This can be seen from the number of street vendors who do a positive treatment on hygiene and food sanitation to fried street food only about 30 -70 %.

Studi Keberadaan Cemaran Formalin dan Timbal (Pb) pada Tahu yang Dijual Pedagang Gorengan Tahu Petis di Sekitar Kampus Universitas Diponegoro

“…Menurut Ihsan, dkk, posisi berdagang di tepi jalan raya memungkinkan penyerapan logam berat dari asap kendaraan bermotor, seperti timbal (Pb). 13 Hasil pembakaran ini, berasal dari senyawa tertrametil-Pb dan tetraetil-Pb yang ditambahkan dalam bahan bakar kendaraan bermotor dan berfungsi sebagai anti ketuk (anti-knock) pada mesinmesin kendaraan. Senyawa ini dapat larut dalam minyak dan air.…”

“…Penelitian Ihsan, dkk pada jajanan gorengan di area sekolah Kota Padang, menunjukkan rata-rata kandungan timbal (Pb) dari makanan gorengan jalanan pada jalan arteri primer berkisar antara 0,249-0,288 ppm dan di jalan lokal sekunder berkisar antara 0,155-0,218 ppm. 13 Kemudian dalam penelitian Tuloly pada jajanan gorengan di lingkungan workshop Universitas Hasanudin Makassar, diketahui bahwa sampel pisang goreng mengandung timbal berkisar antara 0,65 ppm -3,86 ppm. Sedangkan untuk tahu isi kandungan timbalnya berkisar antara 0,93 ppm -3,68 ppm.…”

“…25 Adapun penelitian yang mendukung hasil penelitian ini adalah penelitian Ihsan dkk, yang menunjukan adanya korelasi yang kuat antara kadar timbal yang ada dimakanan gorengan yang terletak di jalan arteri primer (R=0.714) dibandingkan jalan lokal sekunder (R=0.143). 13 Proses penggorengan memungkinkan minyak goreng ikut termakan bersama gorengan dan asap kendaraan bermotor dapat menempel pada minyak goreng karena sifat timbal (Pb) yang lipofilik. Salah satu faktor keberadaan timbal pada minyak goreng adalah penjual tidak menggunakan penghalang di sekitar penggorengan dan tidak menggunakan minyak goreng standar SNI serta menggunakan minyak goreng secara berulang.…”

Lead Content on Fried Foods Against Seller Sanitation and Fried Frequency in the Area of Semarang City

“…Then the condition of the merchandise is opened without a cover (26). The study on the lead contamination of fried food in 2018 street vendors showed that the average Pb content of fried food on the primary arterial road was greater than the fried food on the secondary local road (5).…”

“…The high exposure to pollutants can affect the lead content of fried foods, researchers who perform measurements show that the average Pb content of fried foods on the primary arterial road is greater than the fried foods on the local secondary road namely 0.2672 ppm and 0.2791 ppm. While the lead rate of fried foods on the local secondary road is 0.1851 ppm and 0.1911 ppm (5).…”
