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 to 0.143-80.3 ng ·g, 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.
为调查中国南部沿海地区药品和个人护理产品（PPCPs）的出现情况、分布及潜在风险，采用固相萃取（SPE）和高效液相色谱串联质谱法（HPLC-MS/MS）测定了从潮汕地区7条沿海河流采集的水和水生生物（鱼、蟹和贝类）中的20种PPCPs。结果表明，潮汕地区河流和水生生物中可检测到多达16至18种PPCPs，河流和生物体内PPCPs的浓度分别为0.30 - 2223 ng·L和0.143 - 80.3 ng·g，多种污染物的检出率较高。水和生物样本中存在显著差异。潮汕地区河流中PPCPs的总浓度顺序为黄冈河>连江>黄江>龙江>漯河>榕江>韩江，以磺胺甲恶唑（SMX）和咖啡因（CAF）为主。黄冈河、韩江、连江和漯河的水生生物中PPCPs的总浓度高于龙江和榕江的水生生物，以甲氧苄啶（TMP）、SMX和CAF为主。鱼类中PPCPs的总浓度显著高于蟹类和贝类。生物富集因子（BCF）结果表明，潮汕河流中的多种PPCPs在生物体内积累；其中，鱼类中的BCF值较高，比蟹类和贝类更易生物累积。对潮汕地区12种典型PPCPs的风险商数（RQ）生态风险进行了评估。发现蚤类和藻类的风险显著高于鱼类。SMX、红霉素（ERY）和磺胺嘧啶（SDZ）的RQ值均大于1，对黄冈河和连江的藻类以及黄江的蚤类构成潜在生态风险。
