Abstract
The negative effects of chemical contaminants on tropical marine ecosystems are of increasing concern as human populations expand adjacent to these communities. Watershed streams and ground water carry a variety of chemicals from agricultural, industrial, and domestic activities, while winds and currents transport pollutants from atmospheric and oceanic sources to these coastal ecosystems. The implications of the limited information available on impacts of chemical stressors on mangrove forests, seagrass meadows, and coral reefs are discussed in the context of ecosystem management and ecological risk assessment. Three classes of pollutants have received attention: heavy metals, petroleum, and synthetic organics such as herbicides and pesticides. Heavy metals have been detected in all three ecosystems, causing physiological stress, reduced reproductive success, and outright mortality in associated invertebrates and fishes. Oil spills have been responsible for the destruction of entire coastal shallow‐water communities, with recovery requiring years. Herbicides are particularly detrimental to mangroves and seagrasses and adversely affect the animal‐algal symbioses in corals. Pesticides interfere with chemical cues responsible for key biological processes, including reproduction and recruitment of a variety of organisms. Information is lacking with regard to long‐term recovery, indicator species, and biomarkers for tropical communities. Critical areas that are beginning to be addressed include the development of appropriate benchmarks for risk assessment, baseline monitoring criteria, and effective management strategies to protect tropical marine ecosystems in the face of mounting anthropogenic disturbance.

Watershed streams and ground water carry a variety of chemicals from agricultural, industrial, and domestic activities, while winds and currents transport pollutants from atmospheric and oceanic sources to these coastal ecosystems. The implications of the limited information available on impacts of chemical stressors on mangrove forests, seagrass meadows, and coral reefs are discussed in the context of ecosystem management and ecological risk assessment. Three classes of pollutants have received attention: heavy metals, petroleum, and synthetic organics such as herbicides and pesticides. Heavy metals have been detected in all three ecosystems, causing physiological stress, reduced reproductive success, and outright mortality in associated invertebrates and fishes. Oil spills have been responsible for the destruction of entire coastal shallow‐water communities, with recovery requiring years. Herbicides are particularly detrimental to mangroves and seagrasses and adversely affect the animal‐algal symbioses in corals. Pesticides interfere with chemical cues responsible for key biological processes, including reproduction and recruitment of a variety of organisms. Information is lacking with regard to long‐term recovery, indicator species, and biomarkers for tropical communities. Critical areas that are beginning to be addressed include the development of appropriate benchmarks for risk assessment, baseline monitoring criteria, and effective management strategies to protect tropical marine ecosystems in the face of mounting anthropogenic disturbance.</abstract><subject lang="en"><genre>keywords</genre><topic>Ecotoxicology</topic><topic>Coral reefs</topic><topic>Mangroves</topic><topic>Seagrasses</topic><topic>Chemical contaminants</topic></subject><relatedItem type="host"><titleInfo><title>Environmental Toxicology and Chemistry</title><subTitle>An International Journal</subTitle></titleInfo><titleInfo type="abbreviated"><title>Environmental Toxicology and Chemistry</title></titleInfo><genre type="journal">journal</genre><subject><genre>article-category</genre><topic>Annual Review</topic></subject><identifier type="ISSN">0730-7268</identifier><identifier type="eISSN">1552-8618</identifier><identifier type="DOI">10.1002/(ISSN)1552-8618</identifier><identifier type="PublisherID">ETC</identifier><part><date>1997</date><detail type="volume"><caption>vol.</caption><number>16</number></detail><detail type="issue"><caption>no.</caption><number>1</number></detail><extent unit="pages"><start>12</start><end>40</end><total>29</total></extent></part></relatedItem><identifier type="istex">2A653D7534F024438D583D1A742FF02737D8D4F2</identifier><identifier type="DOI">10.1002/etc.5620160103</identifier><identifier type="ArticleID">ETC5620160103</identifier><accessCondition type="use and reproduction" contentType="copyright">Copyright © 1997 SETAC</accessCondition><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Wiley Periodicals, Inc.</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
