İnsan yaşamının her evresinde gerekli olan süt, C vitamini ve demir dışında makro ve mikro besin öğeleri için iyi bir kaynaktır. Bununla birlikte süt ve süt ürünlerinin pek çoğu laktasyon periyodu esnasında ve üretimde kullanılan alet ve ekipmanlar nedeniyle ağır metal kontaminasyonuna maruz kalabilmektedir. Bu çalışma, çoğunlukla marketlerden alarak tüketilen ısı işlemi görmüş içme sütlerinde kurşun, kadmiyum, civa, arsenik ağır metallerinin olup olmadığını araştırmak amacıyla yapılmıştır. Bu amaçla 2011 yılında İstanbul ili içerisinde bulunan çeşitli marketlerden değişik markalardaki 100 adet UHT (n: 90) ve pastörize (n: 10) süt numunesi temin edilmiştir. Süt numuneleri laboratuvara getirilerek Mars-5 mikrodalga kapalı sistem yaş yakma yöntemiyle yakılmıştır. Daha sonra ICP-OES cihazı ile kurşun, kadmiyum, civa, arsenik kalıntıları yönünden analiz edilmiştir. Elde edilen bulgular doğrultusunda 100 adet ısı işlemi görmüş süt numunelerinin 34 adedi ve 36 adedinde sırasıyla kurşun ve kadmiyum tespit edilememiştir. Bununla birlikte, numunelerin hiçbirinde civa ve arsenik saptanamamıştır. İçme sütü örneklerinin maksimum kalıntı sınırının üzerinde kurşun içermesi ve kadmiyum tespiti, halk sağlığı açısından önemli olarak değerlendirilmiştir.
Milk, which is necessary in every stage of human life, is a good source of macro and micro nutrients, in addition to vitamin C and iron. However, many dairy and dairy products may be exposed to heavy metal contamination during the lactation period and due to the tools and equipment used in production. This study was conducted with the aim of investigating whether there are bullets, cadmium, civa, arsenic, heavy metals in the drinking milk that were mostly consumed from the markets. For this purpose, 100 UHT (n: 90) and pastoriase (n: 10) milk samples were supplied from various markets located in Istanbul in 2011. Milk samples were brought to the laboratory and the Mars-5 microwave closed system was burned by age-burning method. It was then analyzed with the ICP-OES device in the direction of the gun, cadmium, civa, arsenic remains. According to the findings obtained, 34 of the milk samples of 100 thermal processes and 36 of them were not identified, respectively, as well as a shot and kadmium. However, in any of the samples civa and arsenic were not detected. Drinking milk samples contain bullets above the maximum residual limit and the detection of cadmium has been considered important in terms of public health.
Milk that is necessary at every period of human life, is a good source for macro and micro food elements besides C vitamin and iron. Hovewer, most of milk and milk products may contaminate to heavy metal instruments and equipmant that is used in production during lactation period. The aim of this study was to detect of presence of lead, cadmium, mercury, arsenic in heat treated drinking offered for sale in the market. A total 100 UHT (n= 90) and pasteurized milk (n= 10) samples was taken from different markets in İstanbul, in 2011. Milk samples had been burnt with the method of Mars 5 microwave closed system wet burning in the laboratory. Then the presence of lead, cadmium, mercury and arsenic was analysed by ICP-OES apparatus. According to the results, 34 samples and 36 samples of the 100 heat treated milk were not detected in lead and cadmium, respectively. However, mercury and arsenic heavy metals were not found in any of the samples. Drinking milk samples contain lead above the maximum residue limit and presence cadmium was considered important for public health.
