Guidelines for sampling and determination of silicate.
(HELCOM, Helsinki, Finland, 2017)
Silicate is introduced to the Baltic Sea as a result of natural geological processes, as opposed to nitrogen and phosphorus, which levels are affected by human activities.
Although it is not listed among the HELCOM Core ...
Draft guidelines for sampling and determination of total nitrogen.
(HELCOM, Helsinki, Finland, 2017)
Total nitrogen includes all organic and inorganic forms of nitrogen, dissolved as well as suspended or particulate. The results are an estimation of the total amount of nitrogen, not only the dissolved bioavailable ...
Guidelines for Sea-Based Measures to Manage Internal Nutrient Reserves in the Baltic Sea Region.
(HELCOM, Helsinki, Finland, 2021)
The aim of these guidelines is to provide guidance for researchers planning to undertake research projects and for operators and environmental managers planning to implement activities designed to reduce the negative impacts ...
Guidelines for sampling and determination of total phosphorus.
(HELCOM, Helsinki, Finland, 2017)
While determination of dissolved phosphate gives information on the bioavailable pool of phosphorus, an assessment of the total amount of phosphorus is also essential.
Total phosphorus includes all organic and inorganic ...
