An undesirable and unintended, although not necessarily unexpected, result of therapy or other intervention (e g , headache following spinal tap or intestinal bleeding associated with aspirin therapy)
Change in morphology, physiology, growth, development or life span of an organism exposed to air pollution, which results in impairment of functional capacity or impairment of capacity to compensate for additional stress or increase in susceptibility to the harmful effects of other environmental influences (WHO 1994a)
A biochemical change, functional impairment, or pathological lesion that impairs performance and reduces the ability of the organism to respond to additional challenges
An abnormal, undesirable, or harmful effect on an organism, indicated by some result such as mortality, altered food consumption, altered body and organ weights, altered enzyme levels, or visible pathological change (IPCS)
an effect that diminishes the values that establish the area's national significance, impairs the structure and functioning of resources and ecosystems, impairs the quality of the visitor experience, or any combination of these
This is an abnormal, undesirable, or harmful effect to an organism, indicated by some result such as mortality, altered food consumption, altered body and organ weights, altered enzyme levels, or visible pathological change A statistically significant change from the normal state of an organism exposed to a chemical is not necessarily a biologically adverse effect The magnitude of the departure from the normal range, the consistency of the out-of-range effect, and the relationship of the effect to the physiological, biochemical, and total well-being of the organism must be considered An effect may be classed as adverse if it causes functional or anatomical damage, causes irreversible change in the homeostasis of the organism, or increases the susceptibility of the organism to other chemical or biological stress A non-adverse effect will usually be reversed when exposure to the chemical ceases
A harmful result
Any harmful effect to plants and animals due to exposure to a substance (i e , a chemical contaminant) The effect is something that causes harm to the normal functioning of the plant or animal
