Environmental factor or ecological factor or ecofactor is any factor, abiotic or biotic, that influences living organisms.^[1]

Overview[edit]

Apart from the true monogenic genetic disorders, environmental factors may determine the development of disease in those genetically predisposed to a particular condition. Stress, physical and mental abuse, diet, exposure to toxins, pathogens, radiation and chemicals found in almost all^[quantify] personal-care products and household cleaners are common environmental factors that determine a large segment of non-hereditary disease.

If a disease process is concluded to be the result of a combination of genetic and environmental factor influences, its etiological origin can be referred to as having a multifactorial pattern.

As an example of an environmental trigger, a component of a human's drinking water may activate (trigger) a change in a person's body. Such changes are mainly negative ones.^{[citation needed]} Using this example, what is in the drinking water may affect one person entirely differently than another – someone may be affected greatly, whereas someone may not be at all.

Many cancers (osteosarcoma, etc.), along with a plethora of other diseases, are thought^{[by whom?]} to be a result of environmental triggers.^{[citation needed]}

Nitrates may be an environmental trigger for Alzheimer's, diabetes, and Parkinson's disease.^[2]

Environmental triggers for asthma^[3] and autism^[4] have been studied too.

Other[edit]

Environmental factors such as the weather affect business interests.^{[citation needed]}

Electrostatic stabilization is reduced in its efficiency in an electrolyte-containing environment. The effect of electrolyte concentration is mostly described as negative factor for dispersion stabilization. Usually, zeta potential and physical stability decrease at increasing electrolyte concentrat

The m-aminophenylarsonic acid (m-APAA) was immobilized onto the silica gel surface with covalently grafted quaternary ammonium groups via ion exchange. The diazotization of ion-bonded m-APAA resulted in a new solid-phase spectrophotometric reagent for detection of 1-naphtol in environmental water sa

BACKGROUND: Low phosphorus availability is a major factor limiting rice productivity. Since root traits determine phosphorus acquisition efficiency, they are logical selection targets for breeding rice with higher productivity in low phosphorus soils. Before using these traits for breeding, it is ne
