The mass of air surrounding the Earth.
The atmosphere consists of nitrogen (78%), oxygen (21%), and traces of other gases such as argon, helium, carbon dioxide, and ozone.
The atmosphere plays an important role in the protection of life on Earth; it absorbs ultraviolet solar radiation and reduces temperature extremes between day and night. (Source: GreenFacts)
Bioaccumulation is used to describe the increase in concentration of a substance in an organism over time.
Bioaccumulative substances tend to be fat soluble and not to be broken down by the organism. (Source: GreenFacts )
Having to do with the ability to think and reason. This includes the ability
to concentrate, remember things, process information, learn, speak, and

"ECHA is the driving force among regulatory authorities in implementing the
EU's groundbreaking chemicals legislation for the benefit of human health and
the environment as well as for innovation and competitiveness. ECHA helps
companies to comply with the legislation, advances the safe use of chemicals,
provides information on chemicals and addresses chemicals of concern."

"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."

Toxic (damaging) to DNA. Substances that are genotoxic may bind directly to DNA or act indirectly leading to DNA damage by affecting enzymes involved in DNA replication, thereby causing mutations which may or may not lead to cancer or birth defects (inheritable damage). Genotoxic substances are not necessarily carcinogenic. (Source: GreenFacts)
Chemical messengers that help our body do different tasks. Hormones are
produced by the endocrine glands and then
sent all over the body to stimulate certain activities. For example, insulin is
a well-known hormone that helps our body digest food. Hormones regulate our
growth, digestion, reproduction and sexual function.

The act of breathing.
A hazardous substance can enter the body by inhaling an airborne substance or contaminant in the form of gas, fumes mists, vapors, dusts, or aerosols. Once inhaled, contaminants can be deposited in the lungs and/or transported into the blood. (Source: GreenFacts)
An essential structural component of living cells, lipids are a class of oily organic compounds which are insoluble in water but soluble in fats and oils. The lipid class of molecules mainly consists of fats, oils and waxes. (Source: GreenFacts)
Any permanent change in the DNA of a cell.
Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.
Mutations can be harmful, beneficial, or have no effect. If they occur in cells that make eggs or sperm, they can be inherited; if mutations occur in other types of cells, they are not inherited.
Certain mutations may lead to cancer or other diseases.

Persistent organic pollutants (POPs) are chemical substances that persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. This group of priority pollutants consists of pesticides (such as DDT), industrial chemicals (such as polychlorinated biphenyls, PCBs) and unintentional by-products of industrial processes (such as dioxins and furans).
Persistent Organic Pollutants are transported across international boundaries
far from their sources, even to regions where they have never been used or
produced.

A polymer is a high-molecular-weight organic compound, natural or man-made, consisting of many repeating simpler chemical units or molecules called monomers.
Examples of natural polymers are proteins (polymer of amino acids) and cellulose (polymer of sugar molecules).
An example of synthetic polymer is PVC (a polymer of vinyl chloride). (Source: GreenFacts)

Sewage refers to waste-water from homes and industry which is collected and carried away in sewers (pipes or tunnels). When raw waste-water is cleaned in treatment plants the waste product is sewage sludge, which can be used as a fertiliser under certain conditions or deposited in landfills. (Source: GreenFacts )
A substance is soluble if it dissolves in certain fluids. The fluid [gas or liquid] (present in excess) is called the solvent and the substance dissolved in it is called the solute which together form a solution. The process of dissolving is called solvation. A solution that can not hold any more solute is said to be saturated. (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.
GESAMP's UN sponsors: IMO, FAO, UNESCO-IOC, WMO, IAEA, UN, UNEP, UNIDO, UNDP.GESAMP

The thyroid gland consists of two bodies like small walnuts; they are
connected by an isthmus beside the larynx (voice box). The thyroid gland
produces thyroid hormones T3 and T4 which
regulate the metabolism of all cells in the
body. Disorders of the thyroid gland are characterized by the inability to
produce or release sufficient thyroid hormones (hypothyroidism) or the
overactivity of the thyroid gland (hyperthyroidism).
