ABSTRACT
Traditionally, toxicology is an interdisciplinary eld where biology, chemistry, medicine, pharmacology, and environmental sciences collaborate to study the adverse effects of chemicals on living beings (Williams et al., 2000). In that sense, toxicity is understood as the degree to which a substance may be poisonous or can cause a damage. The harmful effects of different physical, chemical, or biological agents on an ecosystem are also of interest to this discipline. Today, it is commonly accepted that all substances may become toxic under the right conditions (dose, duration and route of exposure, shape, chemical nature of the substance, and other individual factors). However, those factors are not enough to understand the potential biological effects of a substance.
