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)

Dental erosion is the loss of enamel and dentine from the tooth as a result of direct acid attack.
It is caused by excessive exposure to acid substances – such as those present in fruit juices and fizzy drinks – that are different from those produced by bacteria involved in the process of dental caries (decay).
Dental erosion is irreversible.
The most common teeth affected by dental erosion are the upper front teeth, although all teeth can be affected. Teeth that have been eroded look glassy, can appear short, and have uneven tips that are easily chipped away.

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).

The European Environmental Agency (EEA) is one of the 15 specialised agencies of the European Union, which handle specific technical, scientific or management tasks. Operational since 1994, the EEA is based in Copenhagen.
"Its mission is to collect, prepare and disseminate timely, targeted, relevant and reliable information on the state and trends of the environment at European level. The founding regulation of EEA stipulates that it is open to countries that do not belong to the European Union but share its concern for the environment. Iceland, Liechtenstein and Norway have been members from the start, and 12 out of 13 candidate countries have joined in 2002 (...)."

The ability of people or animals to produce healthy offspring in abundance.
Unlike fecundity, which measures a potential ability, fertility measures the actual number of offspring of an individual, a couple, a group or a population. It is evaluated by the time to achieve pregnancy.
Please note that "fertility" corresponds to "fécondité" in French and "fecundidad" in Spanish whereas the French word "fertilité" and the Spanish word "fertilidad" mean "fecundity". (Source: GreenFacts)

Small, primitive, bony fish related to the sardine and the anchovy.
Herrings are relatively small but very abundant; they swim in huge schools, feeding on plankton and small animals and plants.
Most herring family species are ocean-dwelling, living in salt water as adults, but returning to freshwater to spawn, and spending the early part of their lives in freshwater. Other herring family members are strictly freshwater fish.
The adult common herring, found in temperate and cold waters of the North Atlantic, is about 30 cm long with silvery sides and blue back. (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

Polychlorinated biphenyls (PCBs) are a family of 209 congeners of structurally similar organic chemicals, ranging from oily liquids to waxy solids. There are 12 PCBs that are dioxin-like and can similarly be toxic and non-toxic. One dioxin-like PCB is 3,4,4',5-Tetrachlorobiphenyl.
PCBs are synthetic and produced either as a singular congener, as a homogeneous group or as a mixture. They are non-flammable, stable, have a high boiling point and exhibit electrical insulating properties. As such, PCBs have been used as coolants and lubricants in transformers and other electrical equipment, as hydraulic fluids, and as plasticizers, pigments, dyes and carbonless copy paper ink. They are also generated and released into the environment as waste byproducts of chemical manufacturing and incineration. (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 tributyltin compounds are a subgroup of the trialkyl organotin family of
compounds. They are the main active ingredients in biocides used to control a
broad spectrum of organisms. Uses include wood treatment and preservation,
antifouling of boats (in marine paints), antifungal action in textiles and
industrial water systems, such as cooling tower and refrigeration water systems,
wood pulp and paper mill systems, and breweries. It is also used for control of
shistosomiasis in various parts of the world. Tributyltin compounds are present
in varying proportions in commercial products; ready-to-use wood preservatives
typically contain as little as 0.3% TBT, but some products used only in
manufacturing may contain as much as 48%.
