多溴联苯醚在市场鲫鱼体内分布和食鱼暴露量

利用气质联用仪(GC-NCI-MS)方法定量分析了台州路桥区河流野生鲫鱼肌肉、菜市场养殖鲫鱼肌肉、肝脏、脑、心脏和卵组织中多溴联苯醚(polybrominated diphenyl ethers,PBDEs)的含量及分布特征,并且评估了当地人通过食鱼的PBDEs暴露量.结果表明,电子垃圾拆解点附近河流鲫鱼肌肉中PBDEs含量显著高于没有明显PBDEs污染源的菜场养殖鲫鱼;PBDEs在养殖鲫鱼组织中分布不均,心脏组织中ΣPBDEs含量最高,均值为18.82 ng·g-1(湿重),卵组织中最低,均值为1.97ng·g-1.菜场养殖鲫鱼各组织中PBDEs同系物分布模式相似,BDE-47是最主要同系物,比例均值大于50%,其次是BDE-183(约20%),再次BDE-99和-153;河鱼肌肉组织中PBDEs同系物与养殖鲫鱼不尽相同,河鱼肌肉组织中主要同系物是BDE-47、-153和-99.这些结果可能暗示了来自上游的简单电子垃圾拆解行为是河流鲫鱼中较高PBDEs含量的一个污染来源.台州居民通过食用河流鲫鱼途径的PBDEs日均暴露量约为29.0 ng,稍微高于其他地区.     

手性多氯联苯在电子垃圾拆解地鱼类体内的分布及累积规律

电子垃圾拆解活动已造成当地鱼类多氯联苯（Polychlorinated Biphenyls,简称PCBs）污染,但手性PCBs在鱼类体内的分布特征和选择性富集则较少有报道.本研究采集了广东省清远市龙塘镇某电子垃圾拆解区附近水塘的鱼类样品,研究鱼肉样品中手性PCBs污染水平、分布规律和对映体选择性.结果表明,在电子垃圾拆解区鱼肉样品中均检测到7种手性PCBs,总PCBs（ΣPCBs）含量为386.7~602.8 ng·g^-1（湿重）,证实当地鱼类已受到手性PCBs的污染.PCB45、PCB91、PCB95、PCB132、PCB136和PCB174在鱼类样品的对映体分数（EF值）与沉积物具有显著差异,表明这些手性PCBs在鱼类体内可能具有对映体选择性富集和代谢作用.不同种类的鱼肉样品中EF值不同,说明它们对PCBs的富集能力不同.鲮鱼、鲫鱼和乌鳢对PCBs的生物/沉积物富集因子（BSAF）分别为0.31~1.71、0.30~1.86和0.50~2.64.根据乌鳢/鲮鱼和乌鳢/鲫鱼食物关系计算的生物放大因子（BMF）范围分别为1.35~4.51和2.17~5.10,表明乌鳢对手性PCBs具有生物放大作用.     

工业园及电子垃圾区大气中的溴代阻燃剂(BFRs)

对广州市主要的工业园以及清远电子垃圾回收拆解园周边空气中溴代阻燃剂（BFRs）进行了分析.结果表明,两地区大气中均以多溴联苯醚（PBDEs）和十溴二苯乙烷（DBDPE）为主（城市地区占比分别为30.0%和68.0%,电子垃圾区分别为74.5%和22.8%）,其中PBDEs在城市地区和电子垃圾区的浓度中值分别为184和411pg/m³;DBDPE则分别为414和193pg/m³.在城市地区,PBDEs的浓度高值多出现在与机械、电子、装饰材料和汽车制造业有关的工业园,新型阻燃剂DBDPE高浓度则多在与机械和电子产品制造业相关的大气中,而1,2-二（2,4,6-三溴苯氧基）乙烷（BTBPE）可能受当地面源污染影响较大.城市地区低分子量的PBDEs的组成波动较大,与五溴联苯醚的禁用（直接排放减少）和来源复杂有关;而电子垃圾区低分子量PBDEs组成稳定,气-固相分配更接近平衡,说明来源较为单一.通过模型估算,城市地区的21个工业园每年约向空气中释放48.0kg的BDE209与163kg的DBDPE,4个电子垃圾拆解园每年约释放31.8kg的PBDEs与12.0kg的DBDPE.     

台州电子垃圾拆解区水和沉积物中多溴联苯醚污染特征与生态风险

以台州某电子垃圾拆解工业园为圆心,在半径为16 km的范围内,由近及远设计了C(3 km)、S(5~10 km)和R(10~16km)三圈共30个采样点,研究了该区域水及沉积物中多溴联苯醚(PBDEs)的污染特征与生态风险.结果表明,水中PBDEs含量为9.4~57.2 ng·L~(-1),平均值为25.9 ng·L~(-1);沉积物中PBDEs含量为3.7~38 775 ng·g~(-1),平均值为2 779 ng·g~(-1);BDE-209均为主要成分.水及沉积物中PBDEs含量的空间分布态势均为:C圈S圈R圈,沉积物中PBDEs含量和离工业园区中心的距离呈极显著负相关(P0.01).与国内外其它地区相比,该调查区PBDEs污染较为严重,电子垃圾拆解是PBDEs污染的主要来源.经推算,该区域近40年的拆卸活动向该地输入的PBDEs总量达30.7 t,其中BDE-209为28.9 t.采用商值法对PBDEs进行初步的生态风险评估表明,拆解核心区(半径为1.5 km)沉积物中五溴联苯醚(Penta-BDEs)的污染程度已达高风险等级,对该地区的生态安全和人群健康可能造成严重影响.     

典型电子垃圾拆解区大气中多溴联苯醚的污染

分别在典型电子垃圾拆解区(E)和其上风向参考点(S)采集了大气颗粒相和气相样品.以研究该区域大气中PBDEs的浓度水平、污染特征和气/固分布特点.分析过程中运用气相色谱.质谱联用仪,负化学离子源(GC-NCI-MS)检测了11种PBDEs结果表明,电子垃圾拆解造成r比较严蘑的PBDEs污染,三溴-十溴联苯醚的浓度范围为51.1～2 685 pg.m-3,(平均值830Pg.m-3),而对照区由于制衣行业的影响也造成了一定程度的PBDEs污染,三溴～十溴联苯醚的浓度范围为1.00-98.9Pg.m-3(平均值28.7 Pg.m-3).在气/固分布的研究中发现,不同的PBDEs在气相和颗粒相的分布比例相差很大,从低溴至高溴PBDEs在气相中的比例呈降低趋势,而在颗粒相中的比例呈上升趋势.电子垃圾拆解区以五溴.联苯醚污染为主,占∑11PBDEs总量的54.3%;而十溴-联苯醚污染次之,占∑11PBDEs总最的23.8%,该污染特征进一步证实了该地区电子垃圾的来源,不仅来自亚洲国家,而且还来自欧美等国家.     

电子拆解区家禽中溴代阻燃剂的污染特征

对某电子废物拆解区散养草鸡进行了12种多溴联苯醚(PBDEs)和十溴二苯乙烷(DBDPE)的污染水平分析.结果显示,草鸡中PBDEs和DBDPE主要通过土壤途径摄入,各个组织中PBDEs均被检出,肾脏中PBDEs含量最高(2071 ng·g~(-1),以脂重计),肝脏中PBDEs平均含量(550ng·g~(-1),以脂重计)远高于肌肉组织(131 ng·g~(-1)(腿肉)和76 ng·g~(-1)(胸肉),以脂重计),DBDPE主要在肾脏和卵组织中检出.同时,本文对电子拆解区居民通过食用草鸡摄入溴代阻燃剂(BFRs)的健康风险进行了初步评价.结果显示,尽管拆解区居民通过食用草鸡暴露PBDEs和DBDPE的风险处于可接受水平,但综合饮用水、大气呼吸和灰尘摄入等其他暴露途径,BFRs健康风险仍不容忽视.     

浙江省台州市电子垃圾拆解地多溴联苯醚浓度水平分布特征和迁移趋势

本研究分析了浙江省台州市电子垃圾拆解地及其周边表层土壤和大气中多溴联苯醚（PBDEs）的浓度水平.结果表明,台州市峰江和滨海的拆解园区、农田和居住区土壤中∑₁₂PBDEs含量（以dw计）范围分别为21.8~1310 ng ·g^-1和6.19~220 ng ·g^-1,PBDEs单体分布没有显著差异.峰江和滨海两地大气中∑₁₂PBDEs质量浓度范围分别为262~3240 pg ·m^-3和840~2990 pg ·m^-3,浓度中值分别为1410 pg ·m^-3和840 pg ·m^-3（冬季）、1590 pg ·m^-3和1960 pg ·m^-3（夏季）,除去BDE209外的11种PBDEs单体分布在冬夏两季呈现显著性差异.通过土-气交换逸度分析发现峰江和滨海PBDEs在土-气分布迁移趋势上呈现一定的差异性.峰江PBDEs的迁移趋势主要以土壤挥发为主,土壤是大气中3~5溴代BDEs的排放源,温度的升高可以促进这一过程,这说明峰江土壤中PBDEs已成为污染释放源,建议应对峰江电子垃圾拆解园区土壤和附近农田开展土壤修复.滨海PBDEs的迁移趋势则主要以大气沉降为主,土壤是PBDEs主要的汇,说明滨海的拆解园成为PBDEs的新排放源.     

中国大气环境中溴代阻燃剂污染特征研究进展

根据近年来大气环境中溴代阻燃剂(brominated flame retardants,BFRs)污染问题的研究成果,综述了溴代阻燃剂在中国大气环境中的污染特征。重点分析了多溴联苯醚(polybrominated diphenyl ethers,PBDEs)和部分Non-PBDE溴代阻燃剂(Non-PBDE类BFRs)在不同类型大气环境中的含量水平及分布特征。文献研究结果表明,中国的室内空气、电子垃圾拆解地、特殊工业园区和经济较发达城市大气环境PBDEs污染较严重,含量水平在102~103pg/m~3。中等发达地区城市大气中PBDEs含量处于世界中等水平,含量为10~102pg/m~3。最主要PBDEs同系物为BDE-209,其次是BDE-47、BDE-99和BDE-28。中国针对大气环境中Non-PBDE类BFRs污染问题的研究较少,现有结果表明,部分地区该类污染物的含量较高,达到103pg/m~3。主要的Non-PBDE类BFRs包括HBCDD、BTBPE及DBDPE。文章最后对中国大气环境中BFRs相关研究中存在的问题进行了简要的总结和展望。     

典型电子垃圾拆解区大气中多溴联苯醚的污染

分别在典型电子垃圾拆解区(E)和其上风向参考点(S)采集了大气颗粒相和气相样品，以研究该区域大气中PBDEs的浓度水平、污染特征和气/固分布特点.分析过程中运用气相色谱-质谱联用仪，负化学离子源(GC-NCI-MS)检测了11种PBDEs.结果表明，电子垃圾拆解造成了比较严重的PBDEs污染，三溴～十溴联苯醚的浓度范围为51.1～2685 pg·m^-3(平均值830 pg·m^-3)，而对照区由于制衣行业的影响也造成了一定程度的PBDEs污染，三溴～十溴联苯醚的浓度范围为1.00～98.9 pg·m^-3(平均值28.7 pg·m^-3).在气/固分布的研究中发现，不同的PBDEs在气相和颗粒相的分布比例相差很大，从低溴至高溴PBDEs在气相中的比例呈降低趋势，而在颗粒相中的比例呈上升趋势.电子垃圾拆解区以五溴-联苯醚污染为主，占∑₁₁PBDEs总量的54.3%；而十溴-联苯醚污染次之，占∑₁₁PBDEs总量的23.8%，该污染特征进一步证实了该地区电子垃圾的来源，不仅来自亚洲国家，而且还来自欧美等国家.     

广州市室内尘土中多溴联苯醚的分布特点及来源

随机采集了广州市46个家庭和12个办公室内尘土样品,同时采集了17个室外尘土样品、2个电视机和2个电脑尘土样品并分析了室内尘土中多溴联苯醚(PBDEs)的含量、单体分布及来源.结果表明,家庭尘土中∑10PBDEs(BDE28,47,66,85,99,100,153,154,183,209之和)的含量为 564.3~9654ng/g,中值和均值分别为 2686,3407ng/g;办公室尘土中∑10PBDEs 的含量为 1737~4408ng/g,中值和均值分别为3133,3179ng/g.室内尘土中PBDEs的最主要单体为BDE209,分别占家庭尘土和办公室尘土∑10PBDEs的97.4%和99.0%.BDE47、99和183在室内尘土中含量也较高.大多数室内尘土中∑10PBDEs的含量高于室外,说明室内可能有重要的PBDEs释放源.室内尘土中PBDEs的主要工业品来源为十溴联苯醚,五溴联苯醚次之,八溴联苯醚较少.     

Polybrominated diphenyl ethers in chicken tissues and eggs from an electronic waste recycling area in southeast China

The levels and distributions of polybrominated diphenyl ethers (PBDEs) in chicken tissues from an electronic waste (e-waste) recycling area in southeast China were investigated. Human dietary intake by local residents via chicken muscle and eggs was estimated. The mean PBDEs concentrations in tissues ranged from 15.2 to 3138.1 ng/g lipid weight (lw) and in egg the concentration was 563.5 ng/g lw. The results showed that the level of total PBDEs (PPBDEs) in the chicken tissue was 2–3 orders of magnitude higher than those reported in the literature. The large di erence of PPBDEs concentrations between tissues confirmed that the distribution of PBDEs in tissues depend on tissue-specificity rather than the “lipid-compartment”. BDE-209 was the predominant congener (82.5%– 94.7% of PPBDEs) in all chicken tissues except in brain (34.7% of PPBDEs), which indicated that deca-BDE (the major commercial PBDE formulation comprising 65%–70% of total production) was major pollution source in this area and could be bioaccumulated in terrestrial animals. The dietary PBDEs intake of the local residents from chicken muscle and egg, assuming only local bred chickens and eggs were consumed, ranged from 2.2 to 22.5 ng/(day kg body weight (bw)) with a mean value of 13.5 ng/(day kg bw), which was one order of magnitude higher than the value reported in previous studies for consumption of all foodstu s.     

北江中上游流域阻燃剂污染特征和风险评估

为探究北江中上游流域的阻燃剂污染状况和风险水平,采用气相色谱-串联质谱(GC-MS/MS)法测定了34个地表水样品和8个沉积物样品中31种阻燃剂的浓度,包括多溴联苯醚(PBDEs)、六溴环十二烷(HBCD)、四溴双酚A (TBBPA)这3种溴代阻燃剂和28种有机磷阻燃剂(OPFRs).采用风险熵法评估了水体中阻燃剂的生态风险,并结合日饮用剂量评估了健康风险.结果表明：(1)地表水中PBDEs和HBCD浓度范围分别为4.78～625.52、225.43～2 209.18 ng/L,未检出TBBPA;沉积物中PBDEs、HBCD和TBPPA含量范围分别为ND～11.82、121.13～395.86和ND～3.30 ng/g.(2)地表水中OPFRs浓度范围为85.80～992.82 ng/L,浓度最高的3种单体分别为TCEP、TPhP和TDCIPP;沉积物中OPFRs含量范围为102.19～748.17 ng/g,含量最高的3种单体分别为TEHP、EHDPP和TCPP.(3)对于地表水中已知毒性参数和健康数据的阻燃剂污染物,其生态风险总体处于中低水平,但BDE-100呈现出高风险,TTP呈...     

Ecotoxicological effects of mixed pollutants resulted from e-wastes recycling and bioaccumulation of polybrominated diphenyl ethers in Chinese loach (Misgurnus anguillicaudatus)

To understand potential ecotoxicological effects of electrical and electronic equipment waste (e-waste) recycling and polybrominated diphenyl ethers (PBDEs) bioaccumulation in loaches, a semi-field experiment using Chinese loach (Misgurnus anguillicaudatus) as experimental fish was performed. Larval loaches were kept into net-cage for three months in an e-wastes recycling site and a reference site in Southeastern China. There was significant difference of the survival rate between the loaches from the e-wastes recycling site (27%, 19/70) and from reference site (70%, 49/70). Histopathological responses were also found in all the livers examined in loaches from the e-wastes recycling site. These results showed that mixed pollutants resulted from e-wastes recycling led to ecotoxicological effects on loaches. The bioaccumulation of polybrominated diphenyl ethers (PBDEs), the main pollutants in e-waste, in loaches was also studied in this e-wastes recycling site, the mean concentrations of total PBDEs in sediment was 6726.17 ng/g wet weight and in water samples was 4.08 ng/L (dissolved phase). BDE209 was the dominant congener in sediment and with relatively high concentration in water. Relatively low concentration of BDE209 (less than 0.01% of total PBDEs) and high concentration of BDE47 (up to 39.34% of total PBDEs) were detected in loaches.     

广东电子垃圾污染区水体底层鱼类对PCBs的富集效应

采用GC/MS分析方法测试了广东电子垃圾回收地水体沉积物中多氯联苯(PCBs)含量,并利用以前测定的底栖性鱼类(鲮鱼、鲫鱼和乌鳢)PCBs含量数据,计算了生物/沉积物富集因子(BSAF)和生物放大因子(BMF),研究底栖性鱼类对PCBs的富集能力及其影响因素.研究表明,沉积物中总PCBs含量达到24.5~38.6μg/g干重,证实当地环境已受到PCBs严重污染.鲮鱼、鲫鱼和乌鳢的BSAF范围分别为0.05~2.52、0.01~1.20和0.01~5.03.根据乌鳢/鲮鱼和乌鳢/鲫鱼食物关系计算的BMF范围分别为0.14~2.23和0.14~4.93, 其中大部分PCB同系物的BMF>1,表明乌鳢对PCBs具有生物放大作用.BSAF及BMF均与PCBs的KOW和氯原子取代数具有显著相关性,说明化合物的理化性质是控制其生物富集的主要因素.     

Ecotoxicological effects of mixed pollutants resulted from e-wastes recycling and bioaccumulation of polybrominated diphenyl ethers in Chinese loach （Misgurnus anguiUicaudatus）

Relatively low concentration of BDE 209 (less than 0.01% of total PBDEs) and high concentration of BDE47 (up to 39.34% of total PBDEs) were detected in loaches.     

多溴联苯醚和新型阻燃剂暴露与儿童肾损伤研究

为加强对多溴联苯醚(PBDEs)和新型阻燃剂(NFRs)环境健康风险的认识,开展PBDEs和NFRs暴露与儿童肾损伤研究. 选择电子垃圾拆解区儿童(暴露组,57例)和对照区儿童(对照组,57例),开展问卷调查和血、尿样采集,检测血中PBDEs、NFRs、铅、脂肪、尿素氮(BUN)、血肌酐(SCr)、尿酸(UA)浓度,尿中镉、镍、β₂微球蛋白(β₂-MG)、N-乙酰-β-D-葡萄糖苷酶浓度. 采用T检验比较两组儿童污染物暴露水平差异,协方差分析比较两组儿童肾功能指标差异,线性回归分析污染物暴露水平和肾功能指标的关联,广义相加模型分析不同污染物对肾功能指标影响的两两交互作用. 结果表明:①暴露组儿童PBDEs和NFRs内暴露浓度(中值分别为230和340 ng/g lipid)显著高于对照组儿童(中值分别为110和160 ng/g lipid),PBDEss浓度与NFRs浓度呈显著相关. ② PBDEs、NFRs浓度与肾功能指标β₂-MG浓度呈显著正相关、与BUN、SCr浓度呈显著负相关. PBDEs与金属的交互作用对β₂-MG和UA浓度存在显著影响. ③ PBDEs和NFRs暴露导致暴露组β₂-MG浓度显著高于对照组、BUN和SCr浓度显著低于对照组,增加暴露组儿童肾损伤的风险. 研究显示,较高的PBDEs和NFRs暴露浓度增加了电子垃圾拆解区儿童肾损伤风险.      

Occurrence of polybrominated diphenyl ethers in fish and shellfish downstream from electronic-waste recycling plants

We measured 39 polybrominated diphenyl ethers (PBDEs) in the muscle tissue of three species of fish (Sciaenops ocellatus, Sparus macrocephalus, and Lateolabrax japonicus) and four species of shellfish (Tegillarca granosa, Cyclina sinensis, Sinonovacula constricta, and Ostrea cucullata) that were collected downstream of electronic-waste recycling plants in Taizhou, China. A total of 24 PBDE congeners (PBDE24) in the samples were detected. The PPBDE24 (total PBDE) ranged from 545.4 to 1688.7 ng/kg ww (wet weight). The mean PPBDE24 concentration was 1382.6 ng/kg ww in fish and 858.1 ng/kg ww in shellfish. The lower brominated congeners were detected at relatively high concentrations in all species. The penta-products, produced from e-waste, were found at relatively low levels. A principal component analysis suggested a significant correlation among di-, tri-, tetra-, and hepta-BDEs for the three species of fish. Similarly, we found a significant correlation between mono- and tri-BDEs in the shellfish. Our results suggested that the processes of PBDE metabolism and elimination were similar in both fish and shellfish. In addition, the primary source of PBDEs appeared to be from the debromination of high brominated PBDEs.     

卤系阻燃剂在东江工业水体中的质量浓度及其分配特征

本研究分析了东江工业水体中卤系阻燃剂的浓度,组成分布以及分配特征.结果表明多溴联苯醚(PBDEs)是水体中的主要的卤系阻燃剂,占总卤系阻燃剂的41.0%,其质量浓度范围为1 102.3~3 666.9 pg·L~(-1),其中BDE209是颗粒相的主要成分.四溴双酚A(TBBPA)占总卤系阻燃剂的32.4%,其质量浓度范围为1 120.9~2 856.5 pg·L~(-1),其他卤系阻燃剂如十溴二苯乙烷(DBDPE)、德克隆(DP)和六溴环十二烷(HBCDs)分别占总卤系阻燃剂的16.3%、7.3%和3.0%,其质量浓度范围分别为397.7~1 736.8、235.7~778.1和9.5~266.8 pg·L~(-1).在对水体溶解相和颗粒相分配的研究中发现,PBDEs、DBDPE、DP和HBCDs主要存在于水体颗粒相中,而TBBPA由于其较大的水溶性,主要存在于溶解相中;卤系阻燃剂的lgK_(oc)与lgK_(ow)之间存在显著的相关性,但是lgK_(oc)实测值与其理论预测值有一定差异,这可能是受控于悬浮颗粒(SPM)含量和溶解有机碳(DOC)含量这两个因素,此外,颗粒相和溶解相之间分配是否达到平衡也是影响测量lg Koc值的因素.     

典型电子废物焚烧区水生生物多溴联苯醚累积特征

对广东清远某电子废物焚烧区封闭水体中水生生物体PBDEs(多溴联苯醚)的累积特征进行了研究. 结果表明,草虾、田螺、河蚌、鲫鱼、鲤鱼、黄鳝和乌鳢等水生生物体内w(∑₂₁PBDEs)(以脂肪质量计)为0.2487~24.50μg/g. 该电子废物焚烧区水生生物PBDEs污染较严重,较我国其他地区开放性水体的水生生物体w(PBDEs)高出1~3个数量级. 其中,底栖动物河蚌和田螺体内PBDEs累积最高,w(∑₂₁PBDEs)分别为11.38和4.968μg/g. 不同同系物在水生生物体内累积差异较大,BDE209是水生生物体PBDEs累积的主要组分,占49.83%~91.48%,八溴代和九溴代BDE也发生了高累积. 营养级是电子废物焚烧区水生生物PBDEs累积的最主要控制因素,但捕食和生活习性对生物体尤其是软体动物PBDEs累积也产生了较大影响.      

A review of polybrominated diphenyl ethers and alternative brominated flame retardants in wildlife from China: Levels, trends, and bioaccumulation characteristics

Accelerated industrialization and urbanization, and unregulated disposal of waste of electric and electronic equipment (e-waste) in China have caused environmental pollution of brominated flame retardants (BFRs). This review summarized the levels, trends, and bioaccumulation characteristics of polybrominated diphenyl ethers (PBDEs) and other potential alternative BFRs including hexabromocyclododecanes (HBCDs), 1,2-bis(2,4,6-dibromophenoxy) ethane (BTBPE) and decabromodiphenylethane (DBDPE) in wildlife from China. PBDE levels in wildlife from China were generally higher than those from other parts in Asia, and were comparable to those from Europe but were lower than those from North America. However, wildlife from the e-waste recycling sites in South China and East China contained much higher PBDEs compared to other reports around the world, suggesting the heavy contamination of PBDEs in these regions. The alternative BFRs were also detected in wildlife, revealing that the animals are exposed to these chemicals, in addition to PBDEs. Temporal trends indicated by levels in marine mammals from South China suggested that PBDE levels increased from the beginning of 1990s to 2000s, but decreased from the middle of 2000s, followed by relatively steady levels. In contrast, HBCDs were found to be continuously increasing from 1997 to 2007, indicating the increasing usage of HBCDs in China in recent years. Compared to PBDE profiles found in other parts, aquatic species and birds from China contained relatively higher contributions of BDE-28 and 209, respectively, suggesting the possible different usage pattern of PBDEs. Future works including keeping monitoring at a reasonable scale and frequency to make sure levels near urban centers indicative of population do not increase are needed. Additionally, focus effort on e-waste recycling regions to look for impacts and to determine if regulation/controls are resulting in lower environmental contamination, and incorporation of sentinel species in monitoring efforts are recommended.
