  • Activity branch
Concepts
  • REFERENCE PERIOD:  The length of time for which data are collected, e.g. a specific day, month or year.
  • POTENTIAL ACID EQUIVALENT INDEX - ACIDIFICATION INDEX ( PAE ):  Measure the potential for acid rain incidence and it`s expressed in number of H+ moles per unit of gas emitted.
  • ECONOMIC ACTIVITY:  Combination of resources such as labour, raw materials, equipment, etc., are joined, leading to the creation of specific goods or services. Regardless of the factors of production integrating the good or service produced, all activities generically imply an input of products (goods or services), a production process and an output of products (goods or services).
