An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. [1] Abiotic factors include ambient temperature, amount of sunlight, air, soil, water and pH of the water soil in which an organism lives.
They include a wide range of environmental factors such as noise, vibration, extreme temperatures, radiation, and ergonomic hazards. Physical hazards may lead to injuries like burns, fractures, hearing loss, vision impairment, or other physical harm.
Ecotoxicology is a relatively young discipline that made its debuts in the 1970s [2] in the realm of the environmental sciences. Its methodological aspects, derived from toxicology, are widened to encompass the human environmental field and the biosphere at large.
To explain these environmental factors, it is necessary to say that most of the factors depend on each other and that they change over the years. Consequently, when one factor changes it also affects the others. The equality for every company is the main characteristic of the factors in an environmental analysis. [6]
Environmental epidemiology is a branch of epidemiology concerned with determining how environmental exposures impact human health. [1] This field seeks to understand how various external risk factors may predispose to or protect against disease, illness, injury, developmental abnormalities, or death.
[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 ...
In epidemiology, environmental diseases are diseases that can be directly attributed to environmental factors (as distinct from genetic factors or infection). Apart from the true monogenic genetic disorders , which are rare, environment is a major determinant of the development of disease.
Environmental monitoring is the processes and activities that are done to characterize and describe the state of the environment. It is used in the preparation of environmental impact assessments , and in many circumstances in which human activities may cause harmful effects on the natural environment .
