Abstract

In this study, the amounts in natural and artificial leathers of heavy metals such as cadmium, cobalt, chrome, copper, mercury, nickel and lead, which are limited in many goods due to their toxicological features, and of aluminum and zinc, which are unlimited, were determined. First, the wet decomposition and the total heavy metal contents of the leathers were specified in ICP-OES. Later, the amount of heavy metal manifesting when the leathers were exposed to sweat and water was determined using ICP-OES. The heavy metal detected in the greatest quantities in natural and artificial leathers was chrome. Small amounts of aluminum, cobalt, copper, nickel and zinc were also determined due to the chemical and physical reactions during the dyeing and finishing processes,. However, neither hexavalent chrome, cadmium, mercury nor lead were encountered in either of the leather types. Finally, heavy metal contents were compared with standard limit values

Özet

Bu çalışmada toksikolojik özelliklerinden dolayı birçok kullanım eşyasında bulunmasına sınırlamalar getirilen kadmiyum, kobalt, krom, bakır, civa, nikel, kurşun ve sınırlandırma getirilmeyen alüminyum ve çinko gibi ağır metallerin döşemelik doğal ve yapay derilerdeki miktarları tespit edilmiştir. Araştırmada; öncelikle derilerin yaş yakma işlemi ile toplam ağır metal içerikleri ICP-OES de belirlenmiştir. Daha sonra, derilerin kullanımı esnasında tere ve suya maruz kalmasıyla açığa çıkan ağır metal miktarları ICP-OES kullanılarak saptanmıştır. Doğal ve yapay derilerde saptanan en yüksek ağır metal elementinin krom olduğu tespit edilmiştir. Boyama ve finisaj prosesleri esnasındaki kimyasal ve fiziksel reaksiyonlardan dolayı küçük miktarlarda alüminyum, kobalt, bakır, nikel ve çinko elementleri tespit edilmiştir. Ayrıca her iki deri tipinde de hekzavalent krom, kadmiyum, civa ve kurşun metallerine rastlanılamamıştır. Son olarak da, ağır metal içerikleri, standart limit değerler ile kıyaslanmıştır
