Determination of some heavy metal levels in soft drinks from Turkey using ICP/OES method

Abstract

Total number of 104 canned soft drinks collected from several regions in Turkey were analysed. The purpose of this study was to determine the levels of heavy metals in the drinks commonly consumed in Turkey. Quantitative determination of heavy metals: arsenic, copper, zinc, cadmium, and lead in all samples was carried out by ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry) method. The mean levels (± SE) of arsenic, copper, zinc, cadmium, and lead were found to be 0.037 ± 0.002 mg/kg, 0.070 ± 0.009 mg/kg, 0.143 ± 0.012 mg/kg, 0.005 ± 0.0003 mg/kg, and 0.029 ± 0.002 mg/kg, respectively, in soft drinks. Our data revealed that arsenic, copper, zinc, cadmium, and lead mean levels found in all soft drinks, collected from several regions in Turkey, were within the Turkish Food Codex (TFC) values.

Measurement and analysis of mineral and heavy metal components in grape cultivars by inductively coupled plasma-optical emission spectrometer (ICP-OES)

“…Environmental pollution is the main cause of heavy metal contamination in the food chain (Bingol et al 2010). Several factors such as exhaustion gases, industry wastes and waste water polluted plants affect heavy metal contents of fruits (Ozcan et al 2012).…”

Electrochemical Biosensors for Food Quality Control

“…Some of them, such as the spectrophotometric analysis with silver diethyldidhiocarbamate and certain modifications of the atomic absorption spectrometry (AAS) and the inductively coupled plasma (ICP) are standardised (DIN 38405-D12; APHA/AWWA/WPCF 3500-As C; AOAC 33.125-33.132 in combination with 25.041 and 25.042; EPA 7061; DIN 38405-D1; APHA/AWWA/WPCF 3500-As B: 3114 B; APHA/AWWA/WPCF 3500-As E: 3120 B; DIN 38406-E22) and are among the mostly applied for arsenic determination in food and beverages (Bingöl et al, 2010;Conklin, 2010;Husáková et al, 2007;Karadjova et al, 2005;Niu Jianjun & Wang Bingwu, 1992;Roberge et al, 2009;Stafilov et al, 2004;Syr-Song Chen et al, 2003;Tašev et al, 2005). Nevertheless, arsenic is one of the few elements for which AAS is not enough sensitive.…”

Jurnal Teknik Lingkungan

“…Kontaminasi dari atmosfir dan lingkungan sekitar, penggunaan pupuk dan pestisida yang berlebihan, serta kualitas air yang tidak baik atau tercemar merupakan beberapa penyebab kontaminasi logam berat terhadap bahan pangan (Bingöl et al, 2010). Kontaminasi logam Cu pada bahan pangan pada awalnya terjadi karena penggunaan pupuk dan pestisida secara berlebihan pada tanaman (Astawan, 2008).…”
