Assessment of the Validity of Introducing Nitrate Vulnerable Zones in Large Areas

The rivers of agricultural catchment areas are particularly vulnerable to eutrophication, which causes nitrate nitrogen (N-NO3) that can be easily leached from the cropland. In 1991, the EU implemented the Nitrates Directive (ND) to identify and reduce the negative effects of nitrates in water. According to this regulation, in 2018, the whole territory of Poland was classified as Nitrate Vulnerable Zone (NVZ). The aim of the study was to assess the validity of the introduction of NVZs in large areas of the river catchment level. Statistical data on agricultural changes for individual provinces of Poland and for the whole country were analyzed. A one-way analysis of variance (ANOVA) was used to assess the N-NO3 content in the water at different locations along the river within four rivers in the Odra basin. The results indicated that higher concentrations are observed in the upper part of the studied catchments, which reached a maximum of 25.0 mg N-NO3·dm−3. However, average values rarely exceeded 11.3 mg N-NO3·dm−3, the limit according to the Nitrates Directive. The large variability in N-NO3 content suggests the need to redefine the actual NVZs since it is essential for the appropriate implementation of programs aimed at restoring water quality according to ND.

“…Furthermore, the population growth rate of Bawean is only 2% within two decades. On the other hand, a tourist visiting Bawean rises gradually from time to time (UPT Dinas Pariwisata Gresik) and can increase anthropogenic activities that lead to water shortage and water pollution (Trimanto et al 2016;Liyanage and Yamada 2017;Kanownika et al 2020). For example, land use change causes declining water infiltration and increases erosion, landslides, sedimentation, and surface runoff (Gao et al 2017;Hasan et al 2020).…”

Abstract. Retnaningdyah C, Arisoesilaningsih E, Vidayanti V, Purnomo, Febriansyah SC. 2023. Community structure and diversity of benthic macroinvertebrates as bioindicators of water quality in some waterfall ecosystems, Bawean Island, Indonesia. Biodiversitas 24: 370-378. Bawean Island is a small island with a fairly dense population, so the need for water resources is quite high. On Bawean Island, several waterfalls have been found that have a hydrological function capable of supplying water continuously for drinking water, raw materials, agricultural irrigation functions and other daily activities that are very important for the people of Bawean Island. However, the quality of the waterfall ecosystem on Bawean Island has never been studied. This study aims to evaluate the water quality of some waterfall ecosystems on Bawean Island using the community structure and diversity of benthic macroinvertebrates as a complement to water physicochemical monitoring. This study used the Ex Post Facto method. The research was conducted at 6 waterfalls found on Bawean Island. The physicochemical quality of the water observed included air temperature, water temperature, pH, Dissolved Oxygen (DO), conductivity, Biochemical Oxygen Demand (BOD), nitrate, and Total Phosphate (TP). The quality of the benthic macroinvertebrate that had been monitored included Importance Value Index (IVI), taxa richness, total density, Shannon-Wiener Diversity Index (H’), and an ecological index, namely the Family Biotic Index (FBI). The monitoring data then be used to analyze the interaction between water quality profiles and macroinvertebrates profiles by conducting Principal Component Analysis (PCA). Based on the results obtained, the water quality in the Bawean Island waterfall, according to the FBI index categorized as Good-Excellent. According to Indonesian government regulation (PP. No. 22 of 2021), some parameters of water quality in Putri and Suwari waterfall were classified as class 2, which can be used for water tourism infrastructure, fish farming also agriculture and the others are categorized as class 3 which is only used for fish farming and agriculture. To maintain good water quality, the waterfall manager needs to control human activities around the waterfall’s ecosystem.

The persistent use of plastics in chemical and industrial procedures has resulted in the contamination of the environment and human health via microplastics (MPs). This study investigates heavy metals, MP, pH, conductivity, and turbidity levels in the Nida River in Poland. The Nida River exhibited the existence of diverse coloured MPs in several physical forms, including fibres, fragments, pellets, and foams. Differences in the number of MPs were noted at five selected locations, with values ranging from 215 to 280 MPs per litre. The mean number of MPs observed was 245 ± 21 per litre. The study of water samples using a scanning electron microscope indicates the existence of various MPs. The morphological study of these MPs revealed patterns of degradation. The energy-dispersive X-ray examination indicates the existence of several elements, such as carbon, nitrogen, oxygen, sodium, magnesium, aluminium, silicon, phosphorus, and others. The water exhibited fluctuations in its levels of heavy metal content. The average zinc concentration in all samples was 96.86 ± 40.25 μg/L, which was the highest. It was followed by Pb 37.6 ± 31.9 μg/L concentration. The turbidity measurement was recorded as 46.38 ± 22.54, the pH level was 7.078 ± 0.33, and the conductivity value was determined to be 1338.8 ± 39.64. The HQ and HI values for adults and children in all age groups were less than one. The carcinogenic excess lifetime cancer risk (ELCR) exceeds the threshold value in most water samples. This study aims to fill the existing gap in understanding the precise measurement of MPs and heavy metals in freshwater sources in Poland. Health risk evaluations are the first step in developing pollution management, control, and water quality standards. Graphical Abstract
