Estimate of the amount of a substance in food and/or drinking water, expressed on a body weight basis that can be ingested daily over a lifetime without appreciable health risk to the consumer on the basis of all the known facts at the time of the evaluation.
It is usually expressed in milligrams of the chemical per kilogram of body weight. ADIs are used for substances that have a reason to be found in food (as opposed to a contaminant - see TDI) and as such, include additives, pesticide residues and veterinary drugs in foods. (Source: FAO WHO (1997) )
The term “active ingredient” is mostly used in drugs to name the substance which is pharmaceutically active.
The term “active substance” is also used in biocidal products to name the component which actually kills, or otherwise controls pests or bacteria.
It is not necessarily the largest or most hazardous component of the product. Some products may contain more than one active ingredient or substance. Non-active ingredients are often called inert ingredients. (Source: GreenFacts)

The suprarenal or adrenal glands, each perched over one of the kidneys, are
double glands. The core, or medulla, manufactures adrenalin, noradrenalin and a
small amount of dopamine. The outer layer of the gland is called the cortex. The
adrenal cortex produces three groups of corticosteroids; mineralocorticoids
(aldosterone) - control electrolyte and water balance, glucocorticoids
(cortisol)- influence carbohydrate
metabolism and sex steroid
hormones (androgens, DHEA).

An aerosol is a collection of microscopic particles, solid or liquid, suspended in a gas.
In the context of air pollution, an aerosol refers to fine particulate matter, that is larger than a molecule, but small enough to remain suspended in the atmosphere for at least several hours.
The term aerosol is also commonly used for a pressurized container (aerosol can) which is designed to release a fine spray of a material such as paint. It has also come to be associated, erroneously, with the gas (propellant) used to expel materials from an aerosol can. (Source: GreenFacts )
Allergies are inappropriate or exaggerated reactions of the immune system to substances that, in the majority of people, cause no symptoms.
Symptoms of the allergic diseases may be caused by exposure of the skin to a

Bacteria play a role in the decomposition of organic matter and other chemical processes. (Source: GreenFacts)

The dense, living tissue that makes up the skeleton of humans and vertebrate animals.
Mature bones are made up of three types of tissue: compact tissue (the hard outer portion of most bones); cancellous tissue (spongy tissue inside the bones that contains bone marrow, which makes blood cells); and subchondral tissue (smooth bone tissue of the joints).
Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones. Compact tissue is also known as hard bone, compact bone or compact cortical bone. (Source: GreenFacts)

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

"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."

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)
Main components of the human eye include:
The retina - Light-sensitive layer at the back of the eyeball onto which incoming light is focused. It contains cells that respond to colours, different shades of grey, and movement. These cells trigger nerve impulses that are carried by the optic nerve to the brain, where a visual image is formed.
The cornea - The dome-shaped, transparent layer that forms the front of the eyeball. It bends light entering the eye into the lens, and hence helps to focus images onto the retina. It contains no blood vessels and is extremely sensitive to pain.
The lens - Transparent elastic structure situated behind the pupil of the eye that focuses incoming light onto the retina. Muscles in the eye can adjust the shape of the lens and make it more flattened to focus on distant objects, or make it more rounded to focus on near objects.
The vitreous humour - The transparent jelly-like substance that fills the eyeball between the lens and the retina. (Source: GreenFacts)

The Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP) is an advisory body, established in 1969, that advises the United Nations (UN) system on the scientific aspects of marine environmental protection.
At present GESAMP is jointly sponsored by nine UN organizations with responsibilities relating to the marine environment, and they utilize GESAMP as a mechanism for coordination and collaboration among them. GESAMP functions are to conduct and support marine environmental assessments, to undertake in-depth studies, analyses, and reviews of specific topics, and to identify emerging issues regarding the state of the marine environment. GESAMP itself today consists of 16 experts, drawn from a wide range of relevant disciplines, who act in an independent and individual capacity. Studies and assessments are usually carried out by dedicated working groups, most of whose members are not sitting members of GESAMP but part of the broader GESAMP network.
