材料和方法在波罗的海以及波兰的沿海和淡水地区使用抓斗采样器（公海）和Ekman-Brige采样器（其他地区）采集表层沉积物（0-10 cm）样品（约500 g湿重）（图1）。将沉淀物置于干净的聚乙烯袋中，取一份子样品（约100 g湿重），在室温下避光风干，然后避光保存直至分析。有机锡分析方法是在微波辅助浸提/消解样品基质后，采用长毛细管柱气相色谱（HRGC）分离和微波诱导等离子体原子发射检测（AED）（Szpunar等人，1996年）。详细地，将0.1- 0.2g的
MATERIALS AND METHODSSurface sediment (0-10 cm) samples (~ 500 g wet weight) were collected using a grab sampler (open sea) and the Ekman-Brige sampler (other areas) in the Baltic Sea, and coastal and freshwater areas of Poland (Figure 1). Sediment was placed in clean polyethylene bags and a subsample (~ 100 g wet weight) was taken and air dried in the dark in room temperature, and then kept in dark until analysis. The method for organotin analysis based on a long capillary column gas chromatographic (HRGC) separation and microwave-induced plasma atomic emission detection (AED), after microwave-assisted leaching/digestion of the sample matrix (Szpunar et al. 1996). In detail a sample of 0.1-0.2 g of
