“…In this case, the application to seawater is largely restricted, as sea salt will bind to the binding sites of the SPE resin, avoiding efficient retention of the target analyte onto the column. In this regard, it has recently been shown that electrodialysis (ED) is a promising sample processing tool for the targeted analysis of pollutants from seawater (Wirth et al 2019(Wirth et al , 2021Lohrer et al 2020). ED is established in many industrial processes, e.g., for seawater desalination during drinking water production, but has found limited application in environmental sciences, so far.…”

“…Recently, a group of resins have become available which base on the target analytes’ specific molecular recognition sites and, therefore, allow a highly selective sample extraction and sample enrichment (Ansari and Karimi 2017 ). Those tailor-made molecularly imprinted polymers were, for example, successfully utilized for the analysis of the antibiotic sulfadiazine (Lian et al 2014 ) and the herbicide glyphosate in Baltic Sea water (Wirth et al 2021 ).…”

The Baltic Sea is among the most polluted seas worldwide. Anthropogenic contaminants are mainly introduced via riverine discharge and atmospheric deposition. Regional and international measures have successfully been employed to reduce concentrations of several legacy contaminants. However, current Baltic Sea monitoring programs do not address compounds of emerging concern. Hence, potentially harmful pharmaceuticals, UV filters, polar pesticides, estrogenic compounds, per- and polyfluoroalkyl substances, or naturally produced algal toxins are not taken into account during the assessment of the state of the Baltic Sea. Herein, we conducted literature searches based on systematic approaches and compiled reported data on these substances in Baltic Sea surface water and on methodological advances for sample processing and chemical as well as effect-based analysis of these analytically challenging marine pollutants. Finally, we provide recommendations for improvement of future contaminant and risk assessment in the Baltic Sea, which revolve around a combination of both chemical and effect-based analyses.

“…It should be mentioned that although the concentration of a single herbicide residue may not be very high in the coastal waters, because the toxicity of residues from the same type of herbicide is additive, their joint toxic effect will be much higher (Cedergreen et al 2008). Compared to the farmland ecosystems and adjacent freshwaters, where the herbicide concentrations range from μ g L −1 to mg L −1 (Calderon et al 2016; Silva et al 2018), the concentrations of herbicides in coastal water are usually much lower (Brodie and Landos 2019; Wirth et al 2020). However, since the ocean represents a huge sink for almost all pollutants, the mixture of herbicides in seawater is much more complex than that in farmland ecosystems (Topaz et al 2018; Dsikowitzky et al 2020), which causes coastal ecosystems to be simultaneously exposed to a higher number of different herbicide residues.…”

Terrestrial input of herbicides has significant impacts on phytoplankton and bacterioplankton communities in coastal waters

Herbicide use has increased very rapidly worldwide in recent decades, and some of these herbicides eventually enter the ocean. At present, herbicide pollution in the ocean has become a global environmental problem. Here, in a field investigation of 22 commonly used herbicide residues (triazine, phenylurea, and amide) in the Bohai Sea and the Yellow Sea, we found that the detection rate of herbicide residues within 100 km from shore was 100%. Notably, triazine herbicides have reached concentrations (up to 12.07 nmol L À1 ) that can significantly disturb phytoplankton and bacterioplankton communities in microcosm experiments. Under exposure to triazine herbicides at close to their total in situ concentrations, the photosynthesis of the phytoplankton community was significantly inhibited, which was reflected by the significant decrease of F v /F m (28.7-63.8%) of the phytoplankton community and dissolved oxygen content (18.1-32.2%) in seawater. Concurrently, the phytoplankton community structure underwent significant changes with the dominant group shifting from diatoms to dinoflagellates, due to the higher atrazine sensitivity of diatoms compared to facultative dinoflagellates. Triazine herbicide also significantly altered the bacterioplankton community structure and inhibited their metabolism of many carbon sources including carbohydrates, amino acids, and carboxylic acids. As phytoplankton and bacterioplankton are closely related, the impact of herbicide on the bacterioplankton community was clearly aggravated by the phytoplankton community. In view of the significance of phytoplankton and bacterioplankton communities in supporting marine food webs and biogeochemical cycles, a continuous increase in herbicide input in the future may seriously affect the stability of coastal oceans.

“…Pesticides and weed killers are commonly used in private households, but more commonly in agricultural areas to promote crop growth. In the Baltic Sea, glyphosate a common weed killer, has been detected in measurable levels [27]. With such toxins made available in water supplies impedes progress toward SDG number 6, clean and sanitary water for all.…”

Impact Assessment Analysis of Sea Level Rise in Denmark: A Case Study of Falster Island, Guldborgsund

2021

View full text Add to dashboard Cite

Anthropogenically-induced climate change is expected to be the contributing cause of sea level rise and severe storm events in the immediate future. While Danish authorities have downscaled the future oscillation of sea level rise across Danish coast lines in order to empower the coastal municipalities, there is a need to project the local cascading effects on different sectors. Using geospatial analysis and climate change projection data, we developed a proposed workflow to analyze the impacts of sea level rise in the coastal municipalities of Guldborgsund, located in Southeastern Denmark as a case study. With current estimates of sea level rise and storm surge events, the island of Falster can expect to have up to 19% of its landmass inundated, with approximately 39% of the population experiencing sea level rise directly. Developing an analytical workflow can allow stakeholders to understand the extent of expected sea level rise and consider alternative methods of prevention at the national and local levels. The proposed approach along with the choice of data and open source tools can empower other communities at risk of sea level rise to plan their adaptation.
