    Bioaccumulation of Zn, Cu and Cd in Channa punctatus.
    (2007-04-13) Shukla, Vineeta; Dhankhar, Monika; Prakash, Jai; Sastry, K V
    Adult Channa punctatus were acutely exposed to LC50 of zinc (18.62 mg/l), cadmium (11.8 mg/l) and copper (0.56 mg/l) separately for 96 hr The concentration of metals was found maximum in liver and minimum in muscles. The degree of accumulation among the five tissues differed and it was in the order: gill>liver>kidney>blood>muscle in case of Zn, gills>kidney>blood> liver>muscle in case of Cd and gills>kidney>blood>liver>muscle in case of Cu exposure.

    Effect of cadmium individually and in combination with other metals on the nutritive value of fresh water fish, Channa punctatus.
    (2002-04-27) Shukla, Vineeta; Rathi, Pratima; Sastry, K V
    Impact of metal cadmium on the nutritive value of Channa punctatus on exposure to a sublethal concentration (1.12 mg/l) of cadmium (Cd2+) for 15 and 60 days has been studied. Among the various parameters selected, the level of moisture in liver and muscle was increased, while decrease was noted in the level of ash, total proteins and inorganic constituents like iron, calcium, inorganic phosphate, sodium and potassium in both liver and muscle in the two types of exposure. The total lipid level of liver increased, while muscle lipid level was decreased. On the other hand, calcium, iron, inorganic phosphate, sodium and potassium levels showed increase in blood. Zinc and selenium decreased the percentage alterations in all the parameters selected for study. In the two types of exposure, zinc was most effective to counteract the cadmium toxicity to fish as in almost all the parameters insignificant alterations were recorded. In combination studies, protection against cadmium toxicity by the two chemicals became more marked with increase in the tenure of exposure.

    Epidemiological studies on bicycle manufacturing industrial workers.
    (2007-07-03) Shukla, Vineeta; Abusaria, Sharda; Dhankhar, Monika; Sastry, K V
    Studies involving health status of bicycle manufacturing industrial workers exposed to chemicals and unexposed workers of the same industry who formed control were conducted at Sonepatin Haryana State, India. Negligence of industrial hygiene and personal protection affected the health of exposed workers adversely Epidemiological spectrum of exposed subjects showed much variation from control. Some unique disorders, such as nail impairments, nasal septum perforation and metal fume fever were observed in exposed workers against their absence in unexposed workers. Data showed occurrence of following diseases in the order of asthma>skin disorders>allergic disorders>bronchitis>all other respiratory diseases>nail disorders and acute pharyngitis>pulmonary tuberculosis and loss of smell and hearing>nasal septum perforation showing high risk factor for 'all other respiratory diseases' and skin disorders. Importance of occupational health surveillance has been highlighted.
