对哥斯达黎加和巴拿马（1 497公里）加勒比沿岸沿着23个珊瑚礁的Siderastrea siderea珊瑚骨架和珊瑚礁沉积物中的12种重金属进行的调查表明，该区域污染程度很高。整个海岸受到数百条河流的影响，河流中的悬浮沉积物越来越多（与毁林有关），这些沉积物将大部分金属从源头带到几公里外的海洋，在那里，它们可能被水流运送和分布在整个地区，甚至到原始的近海珊瑚礁。由于污水排放、石油溢漏（炼油厂和油轮）、滥用农用化学品和化肥以及表土侵蚀造成的环境污染日益严重，中美洲沿海地区目前受到的金属污染（自然和人为）比以往任何时候都多。
A survey of 12 heavy metals in the skeleton of the coral Siderastrea siderea and reef sediments in 23 reefs along the Caribbean coast of Costa Rica and Panama (1497 km) indicates high levels of pollution in the region. The entire coast is influenced by hundreds of rivers increasingly loaded with suspended sediments (associated with deforestation) which carry most of the metals several kilometres from the sources to the sea, where they are probably transported and distributed by currents through the entire region, even to pristine offshore reefs. Central America coastal areas are currently exposed to a larger range of metal pollution (natural and anthropogenic) than ever before, as a result of the increasing environmental contamination from sewage discharges, oil spills (from refineries and tankers), the misuse of agricultural chemicals and fertilizers, and topsoil erosion.
