Analisis Logam Timbal (Pb) Pada lipstik yang Beredar di Kecamatan Kemuning Kota Palembang

Introduction

Analisis logam timbal (pb) pada lipstik yang beredar di kecamatan kemuning kota palembang. Penelitian ini menganalisis kandungan timbal (Pb) pada lipstik di Kecamatan Kemuning, Palembang. Ditemukan 4 dari 5 sampel positif timbal, menunjukkan risiko kesehatan dari kosmetik terjangkau.

Abstract

Timbal merupakan logam beracun alami yang berasal dari kerak bumi, paparan terhadap manusia merupakan masalah kesehatan bagi masyarakat yang sangat signifikan beredar di belahan dunia. Logam berat timbal ditambahkan ke dalam campuran bahan dasar lipstik oleh produsen dengan maksud untuk meningkatkan kinerja dan daya tahan produk. Jenis penelitian yang digunakan adalah eksperimental kualitatif. Penelitian ini bertujuan untuk menentukan ada atau tidaknya timbal pada lipsik yang diperjual belikan di Kecamatan Kemuning Kota Palembang dengan Metode Uji Warna. Didapatkan hasil dari ke 5 sampel, 4 diantaranya positif timbal saat di uji menggunakan uji kualitatif metode uji warna dengan ditandai endapan putih halus yang menandakan positif dengan konsentrasi rendah. Hal ini bisa terjadi ketika larutan sampel deberi HCL dan NaOH larutan bereaksi dan menghasilkan endapan berwarna putih yang menunjukan adanya timbal pada sampel tersebut. Dari hasil tersebut dapat disimpulkan bahwa masih banyak lipstik mengandung timbal dengan harga yang sangat terjangkau terjual bebas di pasar KM 5 Kota Palembang.

Review

This manuscript addresses a pertinent public health concern by investigating the presence of lead (Pb) in lipsticks widely available in the Kemuning District of Palembang City. The study highlights the inherent toxicity of lead and its potential intentional inclusion by manufacturers to enhance product performance, underscoring the importance of such analyses for consumer safety. The research employed a qualitative experimental approach, specifically using a color test method, to achieve its objective of determining lead's presence or absence. The key finding that 4 out of 5 tested samples showed positive indications of lead, albeit at what the authors suggest are low concentrations, points to a potentially widespread issue with affordable lipsticks in the local market. While the study tackles a critical issue, the methodological choice presents some limitations. The reliance on a "qualitative experimental" design using a "color test method" for lead detection, indicated by a "fine white precipitate" from reaction with HCl and NaOH, is a preliminary screening technique. While useful for initial detection, it lacks the specificity and quantitative precision necessary for robust scientific claims regarding concentration levels or definitive risk assessment. The abstract mentions "low concentration," but without quantitative data (e.g., using atomic absorption spectroscopy or ICP-MS), the exact levels and their potential health implications remain speculative. Furthermore, the small sample size of only five lipsticks, even if representative of the "affordable" category, limits the generalizability of the findings across the entire market. Despite these methodological caveats, the study's conclusion that many affordable lipsticks sold in the KM 5 market of Palembang still contain lead is a significant finding with direct implications for public health and consumer protection. It serves as an important initial alert for local regulatory bodies and consumers. Future research should build upon these preliminary findings by employing more rigorous quantitative analytical methods to determine precise lead concentrations, expanding the sample size and geographical scope, and evaluating the health risks associated with chronic exposure to the detected levels. This would provide a more comprehensive understanding of the problem and inform more targeted interventions to ensure the safety of cosmetic products.
