Biological Studies Group A biological overview of theSt. Louis Air Pollution Study may differ in emphasis from those expressed by other study groups, summarized inthe following diagram: One approach is To Man and Indus tr yo c cur ring in soil and Pollutants In The The rectangles as drawn above may be considered as components, processes, or like components or processes. lined arrows is equal to the net change measured between the rectangles. Therefore, when the lined arrows are equal there will be no measurable change and analytically would not be considered important. This statement is basically true mathematically but may have other implications biologically, because of sampling period i n rime and no measurable change was detected,but during a previous nonmeasured period the level or concentration of the pollutant increased and reached the peak of being irritating or toxic,then continuous monitoring, which is not Similar i ly the lined arrows may b e considered as rates of the It is understood that the difference between any two For instance,if a pollutant was measured at a specific point or

The investigations that have been primarily restricted to a011 --willhave to be extended and expanded to include the atmosphere and leaf surfaces. Materials added to the atmosphere as well as those taken from the atmosphere by microorganisms will have to be determined and evaluated. Recent changes in the interpretation of leaf physiology as perennial plants approach senescence may be important in reevaluating the position of plant8 a8 determine i.e., the importance of individual species of plants in the possible uptake of pollutants, the importance of plant communities as "sumps" for pollutante, the determination of materials removed or added to the atmosphere by diseased v8. healthy plants of the same species. It may be necessary to conduct laboratory studies to Animals and their waste products may not be important in the St. Louis area, but they are becoming more and more important in other surrounding areas. Influence of pollutants on animals other than man as well as man requires determination and evaluation. Some of the comments and studies included under microorganisms and plants could also be included under the study of animals. Individual biological studies and their interaction with the physical and chemical studies to be conducted are basic to the understanding of air pollution

The obgeceives of this study would be: 1. To determine what living entities are involved in increasing or reducing the pollution levels in the atmosphere. To determine what biological processes are instrumental in the production or reduction of pollutants. To critically determine the effects of air pollutants on living systems,. Specific objectives, details of investigations and budgets are included within the individual proposals. with a number of the other four interacting groups to both obtain and Similarily each individual will be cooperating --disseminatefindings related to the overall study.
