Effects of consuming raw fish exposed to heavy metal, cadmium (Cd) pollution in white rats

Abstract

Cadmium (Cd) is a contaminant that can cause numerous health effects to living organism and an emerging environment pollutant due to its anthropogenic activity. Living organism around the environment can be polluted by Cd toxicity by inhalation, polluted food consumption, skin contact, and many more. The main objectives of this study were to determine the toxicity effect of Cd from fish ( Oreochromis niloticus) in white rats (Sprague dawley) and also the level of Cd pollution in raw fish and white rats' organs sample by Inductively Coupled Plasma Mass Spectrometry (ICPMS). Three groups of designed samples based on 96hrLC5o of Cd exposure calculated by parts per million (ppm); GA-lowest (1.1721 ppm), GB-medium (2.3442 ppm) and QC-highest ( 4.6883 ppm) while the control groups was remain unexposed to Cd. White rats were euthanized at day one, fourth and seventh and liver and kidney collected for both histological studies and ICPMS readings.
