Definitions of exposome

Wild (2005)1	Exposome is all life‐course environmental exposures (including lifestyle factors) from prenatal period onwards
Rappaport et al. (2010)4	Exposome is the sum of all exposures throughout life, where the environment is the body's internal chemical environment and exposures are all biologically active chemicals in this internal environment
Buck Louis and Sundaram (2012)3	Exposome is a mixture of environmental exposures, including man‐made and naturally occurring chemicals, physical agents (such as noise, vibration and temperature), macrolevel factors (including population density and sanitation) and lifestyle factors
National Research Council (2012)5	‘Eco‐exposome’ extends the concept from the point of contact between the stressor and the receptor, inwards into the organism and outwards to general environment
Miller and Jones (2014)2	Exposome is the cumulative measure of environmental influences and associated biological responses throughout the lifespan including exposures from the environment, diet, behaviour and endogenous processes
