Mass and concentration
Mass concentration is also the metric used
when investigating the release and fate
and transport of conventional contaminants in
the environment. It is likely the best
suitable metric to represent sedimentation of
manufactured NMs after aggregation
3.
A potentialchallenge is to quantify mass
concentration of specific NMs in complex
biological matrices. The NMs can be altered via
dynamic interaction
surrounding me For example, the mass
concentration of fullerene C60 was considered
critical

Effluent Standards
Theyare generally established for the effluent
from industry and municipality waste
Water treatment plant to be discharge into
stream, land, sewer, ocean etc.
Effluent standard system is carried out to
control the following stream standard system.
No detail stream analysis is required to
determine exact amount of waste treatment.
5.
Effluent standardcan serve as a guide to
establish the stream classification or
during
organization of any pollution abutment
program.
Unless the effluent standards are
upgraded, this system does not provide
any effective

Emission standards
Emissionstandards are requirements that
set specific limits to the amount
pollutants that can be released into the
environment.
Many emissions standards focus on
regulating pollutants released
automobiles (motor cars) and other
powered vehicles but they can also
regulate
emissions from industry, power plants,
small equipment such as lawn mowers
7.
Emission Norms:-
Itwas in 1991 that first time emission norms
were introduced in India for petrol
cars, diesel cars followed in 1992.
Emission norms means some rules (which has
specified quantity) decided by the govt
For control of air pollution.
Implementation of mandatory catalytic
converters in 1995 for the 4 Metro cities,
Thus reducing pollution further

Ambient Air QualityStandards
(AAQS) are setup for protecting public health
from adverse effects of air pollution
eliminating or reducing to a minimum, those
contaminants
likely to be hazardous to human health

National Ambient AirQuality
Standards
A National Ambient Air Quality Standard
(NAAQS) is a uniform, national standard
"portion of the atmosphere, external to
buildings, to which the general public has
access.
Primary Standards Primary NAAQS define the
acceptable concentration of an air pollutant in

Require resource consent for an activity
State that a resource consent is not required for
an activity
Allow a resource consent to be granted for an
activity only if it complies
