Marine pollution is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrates or phosphates, stimulate algae growth. Many potentially toxic chemicals adhere to tiny particles which are then taken up by plankton and benthic animals, most of which are either deposit feeders or filter feeders. In this way, the toxins are concentrated upward within ocean food chains. Many particles combine chemically in a manner highly depletive of oxygen, causing estuaries to become anoxic. When pesticides are incorporated into the marine ecosystem, they quickly become absorbed into marine food webs. Once in the food webs, these pesticides can

NIAID traces its origins to a small laboratory established in 1887 at the Marine Hospital on Staten Island, New York Officials of the Marine Hospital Service in New York decided to open a research laboratory to study the link between microscopic organisms and infectious diseases. Dr. Joseph J. Kinyoun, a medical officer with the Marine Hospital Service, was selected to create this laboratory, which he called a "laboratory of hygiene." Kinyoun's lab was renamed the Hygienic Laboratory in 1891 and
