Influence of diesel fuel on the composition and content of free amino acids in the green alga Acrosiphonia arcta
Abstract Arctic ecosystems are the most sensitive and vulnerable to anthropogenic impact, namely, the influence of petroleum products. The aim is to identify the effect of diesel fuel (DF) on the composition of free amino acids (FAA) in Acrosiphonia arcta in Barents Sea. The impact of DF concentrati...
