Trend analysis of cadmium in feedstuff

Abstract

Heavy metals are potent metabolic inhibitors. Cadmium is considered a non-essential element and has high emissions in the biosphere due to anthropogenic activities. The aim is to indicate the importance of cadmium in feedstuff as a potential contamination source. Microwave digestion and graphite furnace atomic absorption spectrometry were used to examine 298 feedstuff samples. A high amount of cadmium above permitted is present in 0.67% of samples. Continuous cadmium monitoring is necessary to prevent its uncontrolled entry into the food chain.
