    Author(s): Birjees Hassan, Md. Niamat Ali* and Humaira Qadri

    Hospitals produce huge volumes of wastewater daily which contain a lot of toxic substances. Hence should be treated properly. Using onion (Allium cepa) root tip system, The current research work were carried out to assess the possible toxic effects of hospital effluents collected from main sewers from different hospitals, in Srinagar city, India. Before testing, Allium bulbs were kept in collected wastewater effluent for 48 hours at different concentrations. In addition, the Allium test was used to estimate DNA damage through comet assay.The results from the Allium test indicate that wastewater at 100% concentration from all the hospitals inhibits mitotic index and show schromosomal disruptions, but is not toxic at low concentration. In the comet assay, a statistical proliferation for DNA strand breaks was found only at higher concentrations of all the four samples. The samples were a.. View More»
