301
Ignitable Capable of burning
Ignition point Lowest temperature at which a volatile material will be vaporized
into a gas that ignites without external ignition source is called ignition point
Immobilization (in the context of solid waste) Converting of waste into a waste
form by means of solidification embedding or encapsulation
Immunology It is a medical specialization that deals with the immune system
In situ conservation Conservation of natural habitats and ecosystems in their natural surroundings
Incidence rate Frequency with which an incidence (like new cases of illness)
occurs in a population over a particular period of time
Incinerator A furnace used for incineration
Incompressible flow Flow in which the fluid density is constant throughout the
flow
Incompressible fluid Fluid whose density is constant everywhere
Incurable disease Disease that cannot be cured
Indicator Factor that identifies and communicates a system’s status
Indoor air pollution Air pollution that occur within enclosed spaces or buildings
Inertia Opposition to any change in velocity of an object
Infant mortality Death of a child younger than 1 year of age
Infant mortality rate Number infant mortality divided by the number of live births
in that population during the same time period
Infectious disease Any disease caused by microbial agents
Ingestion Swallowing
Inhalation Breathing
Interim remedial measure (IRM) An action taken at a contaminated site to
decrease the chances of environmental/human exposure to contaminants
Intermolecular force Force exerted by molecules on each other in an object
Inviscid fluid Fluid that is not viscous
Ionic bond Bond between atoms wherein positively as well as negatively charged
ions are connected together by electrostatic forces
Ionosphere Region of the atmosphere between stratosphere and thermosphere
where ions are generated by photo ionization
Ions Any atom that gains or lose electrons will become electrically charged. Any
charged atom or group of atoms is called ions
Irrotational fluid flow Flow in which streamlines do not loop on themselves
Isohyet A line on a map joining locations that receive the same quantity of rainfall
Isotopes Variants of chemical elements that have the same atomic number but different mass number
Kinetics Relates the action of forces on objects to their resulting motions
Laminar flow Flow in which fluid moves in parallel layers
Land pollution Presence of substances in land at concentrations greater than
their usual levels that affects biotic and abiotic component of environment
significantly
Landfill Engineered solid waste disposal place where waste is deposited in pits/
trenches taking all safety measure to control leachate as well as gases emitted
