The results indicate that the type and number of the substituents affect the toxicity of these compounds directly. A nitro group substitution increases the toxicity of the compounds, and on the contrary, an amido group substitution decreases their toxicity. For multi-nitrobenzenes, the toxicity of the o - or p -substituted nitrobenzene is bigger than that of the m -substituted one.
