What is the difference between transpiration and ..
Precipitation is viewed as the initiating form in the above hydrologic budget. The term runoff is synonymous with stream flow. Storage refers to reservoirs or detention systems which collect waters; for example, a human-made dam (barrage) on a river creates a reservoir for purposes of water storage. Groundwater collects as a storage system and may flow from one location to another; it may be influent or effluent in relation to surface streams. Evaporation is a water surface phenomenon, and transpiration is associated with transmission from biota.

Often causes closure because it: (a) brings CO2 enriched air; and (b) increases the rate of transpiration that causes water stress which causes the stomatato close.
Factors that speed up transpiration will also increase the rate of water uptake from the soil. When water is scarce, or the roots are damaged, it increases a plant’s chance of survival if the transpiration rate can be slowed down. Plants can do this themselves by wilting, or it can be done artificially, like removing some of the leaves from cuttings before they have chance to grow new roots.
Photosynthesis Respiration and Plant Growth
Both BACT and emission standards have a basic fault. They assume that if certain criteria are met at the plant, the target groups will be automatically protected. This is not necessarily so, but once such a system is passed into law, effects on the target become secondary to compliance with the law.

Dispersion should be used with caution. Local meteorological and ground surface conditions must be taken into consideration. For example, in colder climates, particularly with snow cover, there can be frequent temperature inversions that can trap pollutants close to the ground, resulting in unexpectedly high exposures. Similarly, if a plant is located in a valley, the plumes may move up and down the valley, or be blocked by surrounding hills so that they do not spread out and disperse as expected.
9.1 Computation of Evaporation and Evapo-transpiration
* When setting exposure levels in Step 3, it must be remembered that these exposures are total exposures, not just those from the plant. Once the acceptable level has been established, background levels, and contributions from other plants must be subtracted to determine the maximum amount that the plant can emit without exceeding the acceptable exposure level. If this is not done, and three plants are allowed to emit at the maximum, the target groups will be exposed to three times the acceptable level.

The earths natural waters may be viewed as a continuously circulating system as shown in , which provides a graphic illustration of waters in the hydrologic cycle, including both surface and subsurface waters.

The objective of a manager of an air pollution control system is to ensure that excessive concentrations of air pollutants do not reach a susceptible target. Targets could include people, plants, animals and materials. In all cases we should be concerned with the most sensitive of each of these groups. Air pollutants could include gases, vapours, aerosols and, in some cases, biohazardous materials. A well designed system will prevent a target from receiving a harmful concentration of a pollutant.
