Nitrobenzene (NB) is an important organic compound intermediate that is used widely in industry. It is a carcinogen, which induces-among others-thyroid tumors. It was the main compound involved in the Songhuajiang accident in 2007.
Nitrobenzene has been considered as a significant groundwater contaminant due to its wide usage in explosives, insecticides, herbicides, pharmaceuticals and dyes. The potential effects on non-target species such as drake remain unknown.

Inhaled nitrobenzene is carcinogenic and toxic in mice and rats. The spectrum of these responses in animals is dependent on species, sex, and genetic background. NitrobenZene proved to be the most toxic to these two cell lines.
Ozone dosage and initial concentration of nitrobenzene exerted a positive influence on the catalytic ozonation. Increasing zeolite dosage and ozone concentration also enhanced nitro Benzene removal.

| Multiple Sclerosis An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.
