[43] Apart from labile organic carbon, spatial separation of microbes in soil may be influenced by other environmental factors such as temperature and moisture. [44] Other abiotic factors like pH and mineral nutrient composition may also influence the distribution of microorganisms in soil. [45] Variability of these factors make soil a dynamic ...
Environmental factors such as air pollutants, tobacco smoke, emission fumes, and other allergens in the air are said to have an influence on allergic asthma when absorbed through the body. [9] Climate change can affect humans' respiratory health by aggravating respiratory disease or increasing exposure to potential risks of the disease. [10]
Ecologically sustainable development is the environmental component of sustainable development.It can be achieved partially through the use of the precautionary principle; if there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation.
Environmental epidemiology is the study of the effect on human health of physical, biologic, and chemical factors in the external environment, broadly conceived. Also, examining specific populations or communities exposed to different ambient environments, Epidemiology in our environment aims to clarify the relationship that exist between ...
