“…S3). This result indicated that anaerobic reductive debromination was the main process to remove PBDEs in mangrove soil, as reported by previous studies [8,9]. Some anaerobes could effectively use halogenated organic compounds as terminal electron acceptors and replace chlorine/bromine with hydrogen through a process termed dehalorespiration [34].…”

“…Microbial degradation was one of the most important means to remove PBDEs from contaminated soil [9,26]. In the present study, the PBDE dissipation in the soil planted with A. corniculatum was significantly higher than that in the unplanted soil, and more PBDE dissipation occurred in rhizosphere (R) than non-rhizosphere (non-R) soil (Fig.…”

“…BCF in crabgrass, excluding BDE 209 (no detection), is higher than rice near an e-waste recycling site in Qingyuan [36]. Furthermore, crabgrass's BCFs are higher than those of Kandelia obovata and Avicennia marina in BDE 28 and BDE 47 [37], and tobacco and nightshade in BDE 47, BD 99, and BDE 100 [34]. This indicates that ZKHDP seriously affected the BCF in water and terrestrial ecosystems.…”

Carbon dioxide (CO 2 ) flux is a critical component of the global C budget. While CO 2 flux has been increasingly studied in mangroves, better partitioning of components contributing to the overall flux will be useful in constraining C budgets. Little information is available on how CO 2 flux may vary with forest age and conditions. We used a combination of 13 C stable isotope labeling and closed chambers to partition CO 2 efflux from the seedlings of the widespread mangrove Avicennia marina in laboratory microcosms, with a focus on sediment CO 2 efflux in establishing forests. We showed that (1) above-ground part of plants were the chief component of overall CO 2 efflux; and (2) the degradation of sediment organic matter was the major component of sediment CO 2 efflux, followed by root respiration and litter decomposition, as determined using isotope mixing models. There was a significant relationship between C isotope values of CO 2 released at the sediment-air interface and both root respiration and sediment organic matter decomposition. These relative contributions of different components to overall and sediment CO 2 efflux can be used in partitioning of the sources of overall respiration and sediment C mineralization in establishing mangroves.Mangroves contain variably thick organic sediments and are the most carbon (C) rich forests (Donato et al. 2011;Sanders et al. 2016). The high C accumulation capacity of mangroves has been recognized, and termed "blue C," along with saltmarsh and seagrasses (Mcleod et al. 2011;Duarte et al. 2013;Ouyang and Lee 2014). However, studies of mangrove carbon dioxide (CO 2 ) flux vary in the precision of their partitioning. CO 2 flux in mangroves may originate from the canopy, woody debris, root, litter and sediment organic matter (SOM), and is collectively called ecosystem respiration (E e ), which has been usually studied separately as canopy (above-ground parts, E c ) and sediment respiration (the other components, E s ).Mangrove organic material such as leaf litter, if not exported, becomes incorporated in the sediment through decay and chemically modified by microbes inhabiting the mangrove forest floor (Kristensen et al. 2008). In contrast to the intensively studied and relatively established pattern of C exchange between mangroves and nearshore ecosystems (Lee 1995), the pattern of C gas flux released from mangrove sediment is less clear, although there is an increasing interest in this topic and C gas flux at the ecosystem scale (Lovelock 2008;Barr et al. 2010;Chen et al. 2010Chen et al. , 2012Livesley and Andrusiak 2012;Barr 2013;Leopold et al. 2013Leopold et al. , 2015Leopold et al. , 2016Bulmer et al. 2015). A key but poorly known aspect is the partitioning of E s attributable to various components, i.e., root, litter, and SOM (including the microphytobenthos).Laboratory microcosms have been used effectively in studies of mangrove energy pathways. For example, Bui and Lee (2014) evaluated relative contributions of organic matter from mangrove leaf litter an...
