Particulate matter present in air is divided into different categories depending on the size of the particles (aerodynamic diameter).
Fine particles are airborne particles which are smaller than coarse particles. They have an aerodynamic diameter of 2.5 µm or less (PM2.5). The fine particles which are smaller than 0.1 µm are referred to as ultrafine particles (PM0.1).
Please note that ultrafine particles (PM0.1) are part of the fine fraction (PM2.5). (Source: GreenFacts)
In an artificial environment outside a living organism or body. For example,
some toxicity testing is done on cell
cultures or slices of tissue grown in the laboratory, rather than on a living
animal.

The term “oxidative stress” refers to the presence of excessive levels of
highly reactive molecules called free radicals in the cell or a lack of
molecules called antioxidants that can eliminate those free radicals.

Sum of all microscopic solid and liquid particles, of human and natural origin, that remain suspended in a medium such as air for some time. These particles vary greatly in size, composition, and origin, and may be harmful.
Particulate matter may be in the form of fly ash, soot, dust, fog, fumes etc. (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

A virus is a small organism which can infect other biological organisms.
Viruses can only reproduce by invading and taking over cells as they lack the cellular machinery for self reproduction.
They cause diseases in human beings, animals, plants and bacteria.
Examples of human diseases caused by viruses include the common cold, influenza, small pox, AIDS, and cold sores. (Source: GreenFacts)
"The World Health Organization
193 countries and two associate members are WHO’s membership. They meet every year at the World Health Assembly in Geneva to set policy for the Organization, approve the Organization’s budget, and every five years, to appoint the Director-General. Their work is supported by the 34-member Executive Board, which is elected by the Health Assembly. Six regional committees focus on health matters of a regional nature."
WHO's scientific publications are widely recognized as a reference source.
The WHO has a number of regional offices which address the specific issues of those regions.
