Abstract

Pollution by polycyclic aromatic hydrocarbons, lead, mercury, arsenic, cadmium, and chromium is impairing marine ecosystems. Here, we review the effect of these contaminants on coral reefs and mangrove ecosystems, with focus on reef fishes, algae, corals, and oil spills. We also discuss the effects of natural hydrocarbons. Some polycyclic aromatic hydrocarbons display carcinogenic and mutagenic properties. Heavy metals are highly toxic to most marine living organisms, causing reproductive failure, deoxyribonucleic acid damage, and neurological problems. Heavy metals accumulate through the food chain, ending up in humans who eat seafood. Mangroves and coral reefs can be severely impacted with diminished water quality, reduced biodiversity, compromised fish habitats, decreased fish catches, and damaged seagrass beds, ultimately affecting other coastal habitats.

石油烃和重金属污染对珊瑚礁和红树林的影响：综述

多环芳烃、铅、汞、砷、镉和铬的污染正在损害海洋生态系统。在此，我们回顾了这些污染物对珊瑚礁和红树林生态系统的影响，重点是珊瑚礁鱼类、藻类、珊瑚和溢油。我们还讨论了天然碳氢化合物的影响。一些多环芳烃具有致癌和诱变特性。重金属对大多数海洋生物都有剧毒，会导致生殖系统衰竭、脱氧核糖核酸损伤和神经系统问题。重金属通过食物链累积，最终进入食用海产品的人类体内。红树林和珊瑚礁会受到严重影响，水质下降，生物多样性减少，鱼类栖息地受到破坏，渔获量减少，海草床受损，最终影响其他沿海栖息地。

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
