Environmental factors affecting

Professional society promotes the study and control of environmental factors affecting the health and well-being of factory workers, including procedures for monitoring the exposure to toxic materials in the work place. Offers laboratory accreditation and testing programs and informational pamphlets on various health and safety topics.

C02 is not the only factor involved in photosynthesis, so that for its use, other factors must be at levels that do not limit the process. Light, temperature, amount of available nutrients and the relative humidity are other environmental factors affecting photosynthetic activity.

Anaerobiosis is the most studied environmental factor affecting this reaction. Under aerobic conditions, oxygen, and azo dyes are in competition for the reduced electron carriers. 

This section focuses on (1) a discussion of the overall process of biodegradation, (2) a review of the different types, aspects and phases of biodegradation of several classes of organic pollutants, (3) an examination of the environmental factors affecting biodegradation and biotransformation mechanisms, and (4) a description of the different biodegradation and biotransformation pathways. 

Kagawa and Toyama in Tokyo followed 20 normal 11-yr-old school children once a week from June to December 1972 with a battery of pulmonary-function tests. Environmental factors studied included oxidant, ozone, hydrocarbon, nitric oxide, nitrogen dioxide, sulfur dioxide, particles, temperature, and relative humidity. Temperature was found to be the most important environmental factor affecting respiratory tests. The observers noted that pulmonary-function tests of the upper airway were more susceptible to increased temperature than those of the lower airway. Although the effect of temperature was the most marked, ozone concentration was significantly associated with airway resistance and specific airway conductance. Increased ozone concentrations usually occur at the same time as increased temperature, so their relative contributions could not be determined.

The next decade will see both economic and environmental factors affecting process selection and operation. Within the refineries, there is a need to manage effluent streams carefully to reduce the release of pollutants. At the same time, there is a need to remove from products the precursors of pollutants that would otherwise be released during intended use. These requirements combine to place a double burden on the refineries.

The microbial biogenesis and catabolism of DMS, as well as other biogenic sulfur compounds, and the environmental factors affecting these processes deserve attention in order to understand the relationships between acid rain, climate and the global cycle of sulfur. 

It may be deduced from KP = Koc x foc that partition coefficients of hydro-phobic organic compounds in general are dependent upon the chemical of interest (compound-specific properties affect the value of Koc) and the matrix properties of the medium in which it resides. In addition to the fraction of organic carbon present in the sorption phase, additional environmental factors affect partitioning. These factors include temperature, particle size distribution, the surface area of the sorbent, pH, ionic strength, the presence of suspended material or colloidal material, and the presence of surfactants. In addition, clay minerals may act as additional sorption phases for organic compounds. Nevertheless, organic carbon-normalized partition... 

It is tempting to speculate that differences in hydrocarbon phenotypes are correlated with speciation. These variations have been shown to be important for mating or species recognition in a number of species (Drosophilidae and Culicidae in Diptera, Isoptera, etc.). However, it cannot be ruled out that these differences act on the quantity of a specific hydrocarbon and are due to environmental factors affecting hydrocarbon production. In some cases, hydrocarbon production seems to be inherited, suggesting that external factors may not be the only parameters involved. Hybridism and, on the contrary, sexual isolation, can be used to illustrate that chemotaxonomy has an evolutionary basis. This section presents different examples in various orders to illustrate this issue, i.e., Diptera, Isoptera, Orthoptera, and Coleoptera.
