Rules and management of biomedical waste at Vivekananda Polyclinic: a case study.

Hospitals and other healthcare establishments have a "duty of care" for the environment and for public health, and have particular responsibilities in relation to the waste they produce (i.e., biomedical waste).

Study of quaternary aquifers in Ganga Plain, India: focus on groundwater salinity, fluoride and fluorosis.

In marginal and central alluvial plains (Ganga Plain) of India, the inland salinity is continuously increasing, canal network and arid to semi-arid climatic conditions that led to excessive evapotranspiration concentrates the salt in soil and thereby escalating the groundwater salinity. In Mat Tahsil, Mathura district (Ganga Plain) study on shallow and deep aquifer salinity and fluoride was carried out in August 2001 and 2004. Groundwater salinity in some parts is more then 4000 microOmega(-1)/cm.

Groundwater quality monitoring in shallow and deep aquifers in Saidabad tahsil area, Mathura district, India.

Water availability in arid regions is both sporadic and highly variable in quantity. If the water quality shows large variations of salinity and concentration of other chemical constituents with depth and time span, it has considerable effect on the entire hydrological set up of the area. In the Saidabad tahsil area, the deep aquifers that supply water to borewells in the alluvial plain of the Mathura region, Uttar Pradesh, have higher salinity than those of the dugwells from the shallow aquifers.
