Landfill gases Gases generated from the degradation of the waste in landfill
Landslide Rapid movement of a mass of soil, rock, or debris down a slope
Land-use Various types of uses for which land is utilized
Latency period The period between exposure to disease causative agent and the
onset of the health effect
Latent heat Energy released or absorbed by a substance during a transformation in
its physical state that occurs without change in temperature
Latent heat of fusion Quantity of heat required to convert unit mass of solid into
its liquid state without change in its temperature
Latent heat of vaporization The amount of heat required to convert unit mass of
liquid into its vapor state without change in its temperature
Leachate Wastewater generated in land fill or waste dumps
Leachate collection system An engineered system for collecting leachate
Leachate treatment Treatment of leachate
Leaching Process in which chemicals in the waste dissolve the water generating
contaminated fluid
Leapfrogging Ability of developing countries to bypass intermediate technologies
to adopt advanced clean technologies
Leukemia Cancer of the blood or bone marrow
Levee Bund or wall to regulate water levels
Liability Forms of obligation imposed by law
Light pollution (photo pollution) Excessive and inappropriate artificial light
Lightening Atmospheric discharge of electricity
Litter Windblown solid wastes
Littoral zone Zone between high and low watermarks in a coastal region
Local windstorm Strong winds caused due to regional atmospheric phenomena
that are typical for a certain area
Localized disease Ailment that affects one part of the body
Longitudinal strain Ratio of alteration in length to initial length
Long-lived GHGs GHGs that have long residence time in the atmosphere
Low birth weight Baby born with low birth weight less than 2500 g
Lytic cycle Destruction of the infected cell and its membrane by virus for
reproduction
Macro-routing (in the context of solid waste) Creating collection routes by dividing a collection area into small
Macroscopic anatomy (gross anatomy) Anatomy where in organs of a living
organism with are examined with unaided eyesight
Magnetic field A vector field around electric current, a magnet, or changing electric field, in which magnetic forces are noticeable
Magnetic field The area around and object where magnetic force is felt
Magnetic force Force between electrically charged particles due to their motion
Mandate Command, order, or direction, indicating action to be taken
Manometer Devise used to measure differential pressure
Marine debris (Marine litter) Anthropogenic waste that is released accidentally/
deliberately into the sea
