Evaluation of mycotoxins and heavy metals pollution in some types of noodles in local markets

Overview

Mohammed and colleagues measured mycotoxins, fungi, and selected heavy metals in ten noodle types collected from markets in Salah Al-din Governorate, Iraq. The heavy-metal occurrence portion reports per-sample copper and cadmium values in Figures 4 and 5 (n=10) plus the abstracted ranges, and a censored lead (Pb) result of less than 0.1 ppm in all ten samples. The paper reports total-element Cu, cadmium (Cd), and Pb only; it does not report arsenic, mercury, chromium, or metal speciation.

Key numbers

Per-sample bar values are reported in Figures 4 (Cu), 5 (Cd), and 6 (Pb) and were used to compute the distribution statistics above. The source identifies samples by flavor or product descriptor; one descriptor embeds a brand identifier, so per-sample values are not tabulated against descriptors here (Part 12).

Methods (brief)

Ten noodle types were collected from Salah Al-din Governorate markets with three replicates. The heavy-metal method says 10 duplicate noodle samples were dried in an electric oven, ashed in a muffle furnace at 600 C to stable weight, taken up in 5 mL of 5% HNO3, filtered through Whatman No. 1, and analyzed for Cd, Cu, and Pb by atomic absorption spectrophotometry using a Shimadzo-6200 instrument. The source reports total elements only and does not give LOD or LOQ values in the extracted text.

Implications

This source contributes Iraq-market noodle occurrence ranges plus per-sample distribution statistics (n=10) for total Cu and total Cd, and a censored-below-0.1 ppm result for total Pb. It is useful for routing to broad noodle and wheat-based pasta product pages. It is not suitable for inorganic arsenic (iAs), methylmercury (MeHg), or hexavalent chromium (Cr-VI) routing because those analytes were not measured.
