Staining of subfossil chironomid head capsules: a method for improving the extraction process from lake sediments and peat
chironomids stain biological
2021/7/26
Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming.
High cadmium pollution from sediments in a eutrophic lake caused by dissolved organic matter complexation and reduction of manganese oxide
eutrophication lake pollution dissolved organic matter DOM DGT
