Its two central missions are:
To provide equitable access to innovation for all patients;
To ensure the safety of health products throughout their life cycle, from
initial trials to post-marketing surveillance.

The amount of a substance to which a person is exposed over some time period.
Dose is a measurement of exposure. Dose is often expressed as milligram (amount)
per kilogram (a measure of body weight) per day (a measure of time) when people
eat or drink contaminated water, food, or soil. In general, the greater the
dose, the greater the likelihood of an effect. An "exposure dose" is how much of
a substance is encountered in the environment. An "absorbed dose" is the amount
of a substance that actually got into the body through the eyes, skin, stomach,
intestines, or lungs.

The electrical current is a physical phenomenon caused by the displacement of electrons or ions that induce electric fields. By convention, current is considered to be a flux of positive charges.
The intensity of the current is the quantity of charge which passes in a
conductor per unit of time. The intensity of the current is measured in Amperes
(A).

"Following a series of food scares in the 1990s (eg BSE, dioxins…) which undermined consumer confidence in the safety of the food chain, the European Union concluded that it needed to establish a new scientific body charged with providing independent and objective advice on food safety issues associated with the food chain. Its primary objective as set out in the White Paper on Food Safety would be to: “…contribute to a high level of consumer health protection in the area of food safety, through which consumer confidence can be restored and maintained.” The result was the European Food Safety Authority (EFSA).
Set up provisionally in Brussels in 2002, EFSA provides independent scientific advice on all matters linked to food and feed safety - including animal health and welfare and plant protection - and provides scientific advice on nutrition in relation to Community legislation. The Authority communicates to the public in an open and transparent way on all matters within its remit. EFSA’s risk assessments provide risk managers (consisting of EU institutions with political accountability, i.e. European Commission, European Parliament and Council) with a sound scientific basis for defining policy driven legislative or regulatory measures required to ensure a high level of consumer protection with regards to food safety."

"The European Union (EU) is a family of democratic European countries,
committed to working together for peace and prosperity. It is not a State
intended to replace existing states, but it is more than any other international
organisation. The EU is, in fact, unique. Its Member States have set up common
institutions to which they delegate some of their sovereignty so that decisions
on specific matters of joint interest can be made democratically at European
level.This pooling of sovereignty is also called "European integration". "

Contact of the cells of an organism with a substance, micro-organism or radiation. In the case of humans, this may involve contact with a substance or agent by swallowing, breathing, or through the skin or eyes. Exposure may be short-term [acute exposure], of intermediate duration, or long-term [chronic exposure].
Exposure can be divided into external and internal.
External exposure refers to the whole dose to which an organism is exposed.
Internal exposure refers only to that fraction of the initial chemical dose that is absorbed and distributed throughout the body via systemic circulation. (Source: GreenFacts)

The term which is used for the time required for the amount of a particular substance to be reduced to one half of its value when the rate of decay is exponential.
Radioactive half-life refers to the decay of radioactive substances. Iodine-131, for instance, has a half-life of 8 days whereas that of Plutonium-239 is more than 23 000 years.
Biological half-life refers to decay by biological processes. Substances with a long biological half-life will tend to accumulate in the body and are, therefore, particularly to be avoided. Substances with a short biological half-life may accumulate if some becomes tightly bound, even if most is cleared from the body rapidly. There is also the possibility of cumulative effects of chemicals which have a short residence time in the body. (Source: GreenFacts)

An ion is an atom or molecule that is not electrically neutral, but instead carries a positive or negative electrical charge, which is due to the loss or gain of one or more electrons.
An anion is a ion with a negative electrical charge, e.g. chloride (CI-), as opposed to a cation which is an ion with a positive electrical charge, e.g. sodium (Na+). (Source: GreenFacts)

In statistics, mean and median both provide an idea of where the “middle” of a sample is.
The mean (or average) is the sum of all scores divided by the number of scores. For instance the sum of individual ages of persons in a group divided by the number of persons in the group, gives the average age.
The median is the number in a range of scores that falls exactly in the middle so that 50% of the cases are above or below. (Source: GreenFacts)

A plausible and often simplified description of how the future may develop, based on a coherent and internally consistent set of assumptions about key driving forces (e.g., rate of technology change, prices) and relationships.
Scenarios are neither predictions nor projections and sometimes may be based on a “narrative storyline.”
Scenarios may include projections but are often based on additional
information from other sources.

A TDI is an estimate of the amount of a substance in air, food or drinking water that can be taken in daily over a lifetime without appreciable health risk. TDIs are calculated on the basis of laboratory toxicity data to which uncertainty factors are applied.
TDIs are used for substances that do not have a reason to be found in food (as opposed to substances that do, such as additives, pesticide residues or veterinary drugs in foods- see ADI). (Source: GreenFacts)
An expression of the degree to which a future condition (e.g., of an ecosystem) is unknown.
Uncertainty can result from lack of information or from disagreement about
what is known or even knowable. It may have many types of sources, from
quantifiable errors in the data to ambiguously defined terminology or uncertain
projections of human behavior. Uncertainty can therefore be represented by
quantitative measures (e.g., a range of values calculated by various models) or
by qualitative statements (e.g., reflecting the judgment of a team of experts).
