摘要: The Bothnian Sea which is located between Finland and Sweden represents an important source of fresh water to the Baltic Sea. We here present new data on radioactive isotope 129I species from samples collected in December 2009 at different depths Concentrations 129I− (iodide) range 14 × 108 32 atoms/L, while 129IO3− (iodate) concentrations are relatively low fluctuating 1 atoms/L. For nutrients determined same as 129I, significant correlations could be found total P, NO3–N, SiO3–Si, but rather poor with NH4–N. suggest comparable pathway nutrient parameters, NH4–N may different. small amounts negligible change indicate prevailing extensive reduction iodate
