AI Summary & Key Takeaways
AI InsightIt was found that the cadmium concentrations in the sardine fish samples provided from four fish markets with the exception of one fish market, exceeded the value of 0.05 mg Cd/kg (wet weight) limit which is permitted nationally and internationally.

Abstract
The total heavy metal (chromium (Cr), copper (Cu), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb)) present in the muscle tissue of sardine was determined by inductively coupled plasma-mass spectroscopy (ICP-MS) after microwave wet digestion during the winter season of 2010. The mean concentrations of heavy metals in the sardine muscle tissues was 0.21 mg Cr/kg, 1.00 mg Cu/kg, 1.49 mg As/ kg, 0.46 mg Cd/kg, 0.03 mg Hg/kg, and 0.14 mg Pb/kg wet weight. It was found that the cadmium concentrations in the sardine fish samples provided from four fish markets with the exception of one fish market, exceeded the value of 0.05 mg Cd/kg (wet weight) limit which is permitted nationally and internationally. The level of arsenic for one of each group of sardines sampled was higher than the permitted limit of arsenic according to the Australia Food Standard (1.00 mg As/kg). As a result, the comprehensive and periodic controls of heavy metals in fish are important in terms of public and environmental health.
Özet
2010 yılı kış sezonunda sardalya balığı kas dokusunda toplam ağır metal varlığı [krom (Cr), bakır (Cu), arsenik (As), kadmiyum (Cd), civa (Hg) ve kurşun (Pb)], mikrodalga yaş yakma işleminden sonra indüktif olarak eşleştirilmiş kütle spektrometresi (ICP-MS) kullanılarak belirlenmiştir. Sardalya kas dokusu örneklerinde ortalama ağır metal konsantrasyonları 0,21 mg Cr/kg, 1,00 mg Cu/kg, 1,49 mg As/kg, 0,46 mg Cd/kg, 0,03 mg Hg/kg ve 0,14 mg Pb/kg yaş ağırlık olarak tespit edilmiştir. Kadmiyum miktarı (bir balık market hariç) ulusal ve uluslararası izin verilen limit olan 0,05 mg Cd/kg (yaş ağırlık) değerini aşmıştır. Her bir grup için arsenik seviyeleri Avustralya Gıda Standardına göre önerilen limit değerden (1,00 mg As/kg) yüksek bulunmuştur. Sonuç olarak, balıkların ağır metaller yönünden kapsamlı ve düzenli olarak kontrolleri çevre ve halk sağlığı açısından önemlidir.
