title: Hazardous impact of organic arsenical compounds in chicken feed on different tissues of broiler chicken and manure.
abstract: The purpose of this study was to evaluate the translocation of arsenic (As) from feed to different tissues of broiler chicken (leg, breast, liver and heart) and excretory product (manure). The feed, broiler chicken and manure samples were collected from five selected poultry farms. The As concentrations in all samples were determined by electrothermal atomic absorption spectrometry, after microwave assisted acid digestion in closed vessels. The concentrations of As in different chicken feeds were found in the range of 21.3-43.7 μg g⁻¹. The contents of As in different tissues of broiler chicken, liver, muscles and heart were found in the range of 3.07-7.17, 2.15-5.28 and 2.11-6.36 μg g⁻¹, respectively, while manure samples contains 22.8-50.3 μg g⁻¹. The obtained data shows the high correlation coefficient between As contents in feed, excretory product or manure and tissues of broiler chicken in the range of r=0.41-0.83. The high level of As in excretory product may add toxicant to environment, on their disposal.
