研究了Góreckie湖深底沉积物组成的空间和垂直变化，特别是不同流动性和生物有效性的磷组分的变化。这个河道湖的盆地自然分为两部分。底部沉积物收集的Limnos采样器配备了核心切片（原位）的设备。结果表明，在沉积物的表层，积极参与沉积物和水之间的物质交换，磷的含量相当低，只有高达24%的池是结合到生物可利用的馏分。然而，这一数额是足够高，以刺激高奖杯的湖泊周期性状态的水肥大。
The spatial and vertical changes in the composition of the profundal bottom sediments of Lake Góreckie, in particular the changes in the fraction of phosphorus of different mobility and bioavailability, have been studied. The basin of this channel lake is naturally divided into two parts. The bottom sediment was collected by a Limnos sampler equipped with a device for core slicing (in situ). It was shown that in the surface layer of the sediment actively involved in the exchange of matter between the sediment and water, the content of phosphorus was rather low and only up to 24% of its pool was bound to the bioavailable fractions. However, this amount was sufficiently high to stimulate high trophy of the lake with periodical states of water hypertrophy.
