“…Because of a strong electron-withdrawing nitro group, the biodegradation of NB under anaerobic conditions becomes more rapid than that under aerobic conditions, and normally the reductive reaction happens first under natural conditions (Gurevich et al, 1993). Results from Zhu et al (2007) and Li et al (2008) indicated that most of the NB (around 82%) evaporated into the air and 18% was degraded by microorganisms, biodegradation was not the major process responsible for the decrease of NB flux in the Songhua River.…”

“…For instance, the explosion at Jilin Petroleum Corporation in November 2005 resulted in water pollution of the Songhua River. The highest concentration of NB in the Songhua River was 0.51 mg/L (30 times higher than the permissible drinking water level), and persisted for weeks 11,12 . The reported half lives of NB in the environment varied largely, ranging from 2 to more than 625 days 13,14 , which indicated this chemical's toxic effects including its potential genetic toxicity would be long-term.…”

Nitrobenzene (NB) is a synthetic hydrocarbon widely used in industries which is a highly toxic environmental pollutant. To investigate its genetic toxicity to plants, tobacco seedlings were exposed to varying concentration of NB solution for short-term (24 hours). The comet assay was used to examine the DNA damage in tobacco leaf cells under the stress of NB. The DNA migration increased with the dose of NB (from 10 to 100 mg/L). The values of tail intensity (T-DNA), tail moment (TM), and olive tail moment (OTM) increased linearly with NB concentrations between 5 mg/L and 100 mg/L. The results suggest that NB has genotoxic effect on the molecular level in tobacco leaf cells. The comet parameters were significantly different from the control when NB concentrations were higher than 5 mg/L (P⁄0.05), suggesting that tobacco leaf cells have high sensitivity to NB stress. The phenomena demonstrated that the tobacco comet assay could be used efficiently monitor aquatic pollution caused by the toxic chemicals. In addition, a similar evaluation was performed using different NB and antioxidant ascorbic acid (Vc) mixed solutions. The DNA damage in the antioxidant group were significantly lower than those in the group without antioxidant, which illustrates that antioxidants could partially decrease the DNA damage induced by NB. These results suggest that oxidation reactions caused by NB might be one of the factors that lead to DNA damage in plants. However, to process the possible participation of mechanisms of DNA damage caused by NB, further investigation will need.

“…On the other hand, the solubility of NB in water is relatively high (1900 mg/L at 20 • C), therefore, when it is released into rivers, it is hydrated and partially dissolves in water. When an explosion occurred at the petrochemical plant owned by Petro China Jilin Petrochemical Company in Jilin, Jilin Province, China, on November 13, 2005, approximately 100 tons of chemicals, including benzene, aniline and NB, were released into the nearby Songhua River [4,8,9]. Consequently, the water supply of Harbin, a city on the banks of the Songhua River, was cut off for several days because the city obtained its water from the river.…”
