Foreword
The protection of environment against mercury
pollution is a very typical problem in view of its potential hazards
to human b~ings. The major con- sumer of mercury is the Chlor-alkali
Industry and maximum proportion of mercury consumed, apart from
carryover with products, is released into the environment through
cell room ventilation, brine sludge and waste streams. .
The Water (Prevention
and Control of Pollution) Act, 1974 provides for a consent system
by which control of pollution at the sources of emanation prior
to discharge into the environment can be effected administratively.
The Central Pollution Control Board under this Act, in collaboration
with the State Po11ution Control Boards, initiated a nationwide
programme of mercury po11ution control in the caustic soda industry
in the year 1982. Prior to this programme, the Minimal National
Standards (MINAS) were developed for the industry after considerable
interaction with the Alkali Manufacturers

Association of India. The target date for achieving the MINAS was
fixed as January 31, 1984. The present report is a case study which
brings out an assessment of mercury po11ution problem and its control
