“…In the PMC area, the DO was analyzed to have an inverse correlation with the BOD (r = −0.43) and inversely correlate with the BOD, COD, and EC in the NMC area. As expected, the DO is often inversely correlated with BOD, because microorganisms use oxygen in the water to decompose organic substances, so the higher the content of biodegradable organic matter, the lower the DO value and vice versa [13,37,45]. Besides, it is interesting that DO was found to have a very close positive correlation with Al 3+ in the NMC area (r = 0.95); on the contrary, COD showed an inverse relationship with Al 3+ (r = −0.62).…”

“…The water quality in wetland ecosystems is considered the major determinant of the habitats of various wetland organisms. Therefore, the water quality in wetlands has been of interest to scientific researchers [7,[12][13][14]. Water quality monitoring in wetland environments can be measuring the physical and chemical water quality parameters, evaluating the eutrophication, and using biological parameters [15].…”

This study was conducted to assess the water quality affected by different land use patterns in U Minh Ha National Park, Ca Mau, Vietnam. This study determined the water quality characteristics in three land use types (Acacia hybrid, planted melaleuca cajuputi, and natural melaleuca cajuputi) at different plant ages on two acid sulfate soil layers in the rainy season (8/2018) and dry season (4/2019) using nine water quality parameters. Multivariate statistical analyses were applied to evaluate the correlation and spatial and temporal variations in the water quality. The study results showed that the water quality in S-ASS was more polluted than that in D-ASS, characterized by low pH; the EC, organic matters (BOD and COD), nutrients (N-NH4+ and N-NO3−), and metal ions (Al3+ and Fe3+) were high; and the EC, BOD, COD, Al3+, and N-NO3− were determined high in D-ASS. The NMC area was noted to have high concentrations of organic matters and nutrients, while the factors specific to acidic soil were found to be higher in the AH and PMC areas. The water quality in the rainy season tended to be more polluted than that in the dry season. The cluster analysis grouped the land use patterns on S-ASS and D-ASS in both seasons into four groups, with a clear similarity between the wet and dry seasons in the areas at various plant ages. The seasonal variations of the water quality of the three land use types were distinguished by the main parameters, including pH, EC, BOD, N-NO3−, and Al3+ (S-ASS) and EC, BOD, N-NO3−, N-NH4+, and Fe3+ (D-ASS). Therefore, there is a need for better water management measures in the rainy season and focus on the key parameters causing water quality variations in each area. The findings in this study provided important information for the future water quality monitoring for both agricultural production and conservation in the national park.

Vertebrates in the “Palude di Torre Flavia” Special Protection Area (Lazio, central Italy): an updated checklist

et al. 2021

Here we present the checklist of the vertebrates of the “Palude di Torre Flavia”, a protected area in Tyrrhenian central Italy (Special Protection Area according to the Directive 2009/147/EC). To draw up the checklist, we collated all the records found in the literature, in private collections, and in the Ornitho.it website database, as well as sporadic historical observations. We obtained evidence documented between 1981 and 2020 for 291 taxa of which 259 native, 26 allochthonous and 6 domesticated species in 5 classes: 5 actinopterygians (4 native species and 1 allochtonous), 2 amphibians, 20 reptiles (11 native species and 9 allochthonous; the last being all freshwater terrapins), 244 birds (including 14 non-native taxa and 6 domestic forms) and 20 mammals (including 2 allochthonous). Forty-three species are listed as of conservation concern on a national scale. The area has shown to be an important biodiversity hotspot, and a major stopover site for migrating birds. Further research should be focused on some still poorly investigated taxonomic groups, in particular: Actinopterygii, Amphibia Salamandridae, Carnivora Mustelidae, and Chiroptera.

“…Models for predicting residual DOM or DOM removal after coagulation have enabled the water treatment industry to estimate and/or predict the performance of chemical treatment processes. These models are normally empirical and semi‐empirical based on a regression analysis that considers the amount and character of NOM in raw and treated water (Chiemchaisri et al ., 2008; Xie et al ., 2012; Murshed et al ., 2013; Sabia et al ., 2018). By establishing the empirical or semi‐empirical relationships of water quality parameters, the coagulation dose can be estimated to achieve targeted water quality.…”

Coagulation is the most commonly used chemical treatment process that is used to remove contaminants from drinking water. In this study, the Log‐Dose‐Response (LDR) model and theoretical isotherm models (Langmuir and Freundlich) were employed to predict the DOC removal in the coagulation process during La Nina events. The six months water samples were collected during an intense La Niña cycle at various locations along the River Murray and elsewhere in South Australia. The Jar testing was conducted with different Alum dose and pH levels, that is, at 5.5, 6.0 and 7.0. The result indicates that the optimum dose of Alum for DOC removal is 15.0 mg/L and the LDR model is the best one for predicting the DOC removal in the coagulation process. The mean of standard error for this model is less than 5% for all pHs compared to Langmuir and Freundlich predictions with a value of 11% and 8%, respectively. Moreover, the standard deviation for the LDR model was low at 2.49, 1.22 and 0.75 for pH 5.5, pH 6.0 and pH 7.0, respectively.
