Anomalies in toxicology can occur due to a multitude of reasons. One of the primary causes is genetic variability among organisms, which can lead to different responses to the same substance. Experimental errors, such as incorrect dosing or measurement inaccuracies, can also result in anomalous data. Additionally, environmental factors, such as temperature and humidity, can influence the outcome of toxicological studies. Lastly, unknown interactions between chemicals can produce unexpected toxic effects.
