Pinocytosis Engulfment of liquid droplets by membrane from surroundings
Plane wave A wave whose wave fronts are in finite parallel planes
Plankton Microscopic aquatic organisms that drift or swim weakly
Plantae (plants) Multicellular eukaryotic organisms characterized by photosynthetic nutrition, cells with cellulose in their walls, absence of nervous system
Plume Long band or column of chemicals moving away from its source
Point source Single identifiable stationary source of pollution
Pollution monitoring Sampling as well as measuring of pollutants
Polymorphism Quality or character occurring in many different forms
Porous Containing holes or voids
Postneonatal mortality Death occurring from one month to one year after birth
Potential difference The variance in electrical potential amid two points
Power Rate of doing work is called power

organism for food
Preterm birth Birth with the gestation period less than 37 weeks
Prevalence Proportion of a defined population affected by a sickness at a specified
point in time
Primary disease Disease arising spontaneously which is not associated with or
earlier disease
Progressive disease Disease that is progressing or worsening
Protected area Area which is regulated and managed to achieve conservation
objectives

entitled “treaty” or “convention”
Protocol (in the context of scientific procedure) The detailed plan for conducting
a scientific procedure
Protons Positively charged particle of an atom
Pulmonology Branch of medical science that is concerned with ailments involving
the respiratory tract
Putrefaction Biodegradation in which foul smelling compounds are formed
Putrescible Decomposable
Pyrolysis Thermochemical decomposition of organic substance in the absence of
oxygen to convert solid wastes to liquid as well as gaseous fuel
Quality assurance System of procedures, audits, checks and corrective actions to
ensure quality
Radiation pollution (radioactive pollution or nuclear pollution) Pollution
caused by radioactive materials
Radical A group of atoms with a charge that goes through a reaction without
change is called a radical
Radon A radioactive gas emitted from soils and rock
Rangeland Unmanaged grasslands, savannas, shrub lands and tundra
Reactivity The rate at which a chemical material tends to undergo a chemical
reaction
