摘要: Abstract The risks of heavy metal in Futian mangrove forest sediment were assessed using the acid-volatile sulfide (AVS) and simultaneously extracted metals (SEM) methods. results indicated that AVS distributions more variable than SEM at all 16 sampling sites. positive correlation between their similar formative existing conditions acted as an important carrier for SEM. major component was Zn (69.7.3–94.2%), whereas Cd contribution (the most toxic present) to no 1%. possible adverse effects caused by ten sites may be due higher levels SEMs, rather AVSs. total organic carbon (TOC) metal-binding phase sediments. Taking into account TOC concentration, there any
