“…The low concentration of NO 3 − could be effectively removed through the denitrification process, whereas NH 4 + at different concentrations in the influent could be significantly removed by the bioretention system which may be attributed to the removal by the adsorption process through the bioretention media [66,87]. An investigation carried out by Bučiene and Gaigalis [88] revealed that nitrogen concentration in effluent was positively correlated with its concentration in the runoff. In addition, NO 3 − concentration in the effluent was linearly increased with an increasing TN concentration in the effluent [89].…”

One of the best management practices (BMPs) for stormwater quality and quantity control is a bioretention system. The removal efficiency of different pollutants under this system is generally satisfactory, except for nitrogen which is deficient in certain bioretention systems. Nitrogen has a complex biogeochemical cycle, and thus the removal processes of nitrogen are typically slower than other pollutants. This study summarizes recent studies that have focused on nitrogen removal for urban stormwater runoff and discusses the latest advances in bioretention systems. The performance, influencing factors, and design enhancements are comprehensively reviewed in this paper. The review of current literature reveals that a bioretention system shows great promise due to its ability to remove nitrogen from stormwater runoff. Combining nitrification and denitrification zones with the addition of a carbon source and selecting different plant species promote nitrogen removal. Nevertheless, more studies on nitrogen transformations in a bioretention system and the relationships between different design factors need to be undertaken.

“…Researchers from different countries [57][58][59] determined that due to higher precipitation, soil water content and plant vegetation properties, the leaching of soluble mineral compounds with drainage runoff occur early in the spring, or in late autumn, and also during mild winters, when positive air temperatures prevail and soils are early ploughed. These are called "critical seasons" because the concentration of nutrient compounds can be 2-5 times higher than more normal seasons and the nutrient compounds are easily lost.…”

The causal relationship of changes in nitrogen and phosphorus concentrations in the Akmena-Danė River and its largest tributary, the Eketė River, was analysed for the period 1999–2014. Results showed that the annual concentrations of NH4-N and PO4-P significantly decreased in the Eketė River over the research period. NH4-N also significantly decreased in the Akmena-Danė River. This was mostly due to the shrinkage of agriculture, i.e., the reduction in agricultural land area, total farm and animal numbers and other agricultural activities. The effect of other factors such as air temperature, precipitation rate, shift of precipitation maximum from warm to cold season, drainage runoff from the large tile-drained areas, soil types and the slight increase in forested land was also examined.

“…However, a trend was not found in the current dataset indicating overall stable conditions. A difference of P deposition depending on surrounding landscapes was described in another long-term dataset (central part of Lithuania, 1988-1999 site 1, and 1996-2007 site 2, [34]). Highest depositions were found during the 1980s and in agricultural areas.…”

Magnitude and influence of atmospheric phosphorus deposition on the southern Baltic Sea coast over 23 years: implications for coastal waters

Background: There are various ways for nutrients to enter aquatic ecosystems causing eutrophication. Phosphorus deposition through precipitation can be one pathway, besides point sources, like rivers, and diffuse runoff from land. It is also important to evaluate recent trends and seasonal distribution patterns of phosphorus deposition, as important diffuse source. Therefore, a long-term dataset was analysed including 23 years of daily phosphate bulk depositional rates and 4.5 years of total phosphorus (TP) bulk depositional rates. The study area was at the coastline of the southern Baltic Sea, an area which shows severe eutrophication problems. Results:The median daily deposition of phosphate was 56 µg m −2 day −1 (1.8 µmol m −2 day −1 ) at 4222 rain events. The median annual sum of phosphate deposition was 16.7 kg km −2 a −1 , which is comparable to other European areas. The annual TP deposition depended strongly on methodological aspects, especially the sample volume. The median TP-depositional rates ranged between 19 and 70 kg km −2 a −1 depending on the calculated compensation for missing values, as not every rain event could be measured for TP. The highest TP-depositional rates were measured during summer (e.g. up to 9 kg TP km −2 in August 2016). There was no trend detectable for phosphate-and TP-depositional rates over the sampled period.Conclusions: Deposition of P is a considerable nutrient flux for coastal waterbodies. Median total annual deposition contributed 3 t (phosphate) to 10 t (TP) per year into the adjacent lagoon system, being therefore close to annual riverine inflows of 10 t phosphate and 20 t TP per year. However, the impact of precipitation is predicted to be higher in lagoon parts with fewer point sources for phosphorus, if equally distributed over the area of interest. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
