| 中文摘要 |
| 为了解南海海岸带地区河流及其生物体中药物及个人护理用品（pharmaceuticals and personal care products，PPCPs）的污染水平、空间分布特征及其潜在风险，本研究采用固相萃取和高效液相色谱-串联质谱测定了潮汕地区7条河流水样及生物样品中的20种PPCPs.结果表明，高达16和18种PPCPs分别能在潮汕入海河流和生物体中检测出，河流和生物体中目标物的含量范围分别为0.30~2223 ng ·L-1和0.143~80.3ng ·g-1，且多种污染物检出率较高.PPCPs在潮汕各河流和生物中的含量差异较大，PPCPs浓度最高的河流为黄冈河、练江和黄江，磺胺甲（口恶）唑和咖啡因是主要的污染物；黄冈河、韩江、练江和螺河生物体中的PPCPs总浓度较高于龙江和溶江生物中PPCPs的含量，甲氧苄氨嘧啶、磺胺噻唑和咖啡因是生物中主要的污染物，鱼类的PPCPs含量总量明显高于蟹类和贝类.计算所得河流生物浓缩系数（BCF）值显示多种目标物在潮汕生物体内具有累积性，其中鱼类中的BCF值较高，比蟹类和贝类更易形成生物累积.运用风险商值模型（RQ）评价12种PPCPs在潮汕地区河流生态环境中的潜在风险，发现蚤类和藻类遭受的风险明显高于鱼类，若以二者为保护对象，磺胺甲（口恶）唑、红霉素和磺胺嘧啶的RQ值均大于1，分别对黄冈河藻类生物、练江藻类生物以及黄江蚤类生物具有潜在生态风险. |
| 英文摘要 |
| To investigate the occurrence, distribution, and potential risks of pharmaceuticals and personal care products (PPCPs) in the South costal area of China, a total of 20 PPCPs in water and aquatic organisms (fish, crab, and shellfish), obtained from 7 coastal rivers of the Chaoshan area, were determined using solid-phase extraction (SPE) and high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). The results showed that up to 16 to 18 kinds of PPCPs could be detected in the rivers and aquatic organisms of the Chaoshan area, and the concentrations of PPCPs in the rivers and organisms ranged from 0.30-2223 ng ·L-1 to 0.143-80.3 ng ·g-1, respectively, with a high detection rate for many pollutants. Significant differences were observed in the samples of water and organisms. The total concentration of PPCPs in the rivers of the Chaoshan area was in the order of Huanggang River > Lianjiang River > Huangjiang River > Longjiang River > Luohe River > Rongjiang River > Hanjiang River, with the dominance of sulfamethoxazole (SMX) and caffeine (CAF). The total concentrations of PPCPs in the aquatic organisms from the Huanggang River, Hanjiang River, Lianjiang River, and Luohe River were higher than the concentrations of PPCPs in the aquatic organisms from the Longjiang River and Rongjiang River, with a dominance of trimethoprim (TMP), SMX, and CAF. The total concentration of PPCPs in fish was significantly higher than that in crab and shellfish. The results of bioconcentration factor (BCF) showed that a variety of PPCPs were accumulated in the organisms from the Chaoshan rivers; among them, the BCF value in fish was higher, which was more likely to bioaccumulate than crabs and shellfish. The ecological risks in terms of risk quotient (RQ) for 12 typical PPCPs were assessed in the Chaoshan area. It was discovered that the risk for fleas and algae was significantly higher than that for fish. The RQ values of SMX, erythromycin (ERY), and sulfadiazine (SDZ) were all greater than 1, which posed potential ecological risks for algae in the Huanggang River and Lianjiang Rivers and for fleas in the Huangjiang River. |
