Organic matter lability modifies the vertical structure of methane-related microbial communities in lake sediments [PDF]
Eutrophication increases the input of labile, algae-derived, organic matter (OM) into lake sediments. This potentially increases methane (CH4) emissions from sediment to water through increased methane production rates and decreased methane oxidation ...

How we can disrupt ecosystem of urban lakes– pollutants of bottom sediment in two shallow water bodies [PDF]
The research covered two lakes: Karczemne and Domowe Małe, which served as receivers for rainwater and municipal or industrial sewage. The sediment cores were obtained using a Kajak tube sampler.

Speciation and spatial distribution of nitrogen in surface sediments of in Ming Lake [PDF]
To reveal the diverse occurrence forms and spatial distribution characteristics of nitrogen in the surface sediments of Ming Lake, a sequential leaching method was employed to determine the nitrogen in the surface sediments of Ming Lake. The results show
