Abstract An automatic microanalysis method for the determination of total organic carbon (TOC) in wastes is proposed. This quick, reliable, accurate, and able to overcome interference carbonate‐carbon. The obtained values TOC 38 samples consisting city refuse, sewage sludges, manures, plant residues are correlated with those oxidable (OXC) measured by traditional Walkley Black duly adapted materials, linear, power, exponential regression equations calculated. use easily allows transform OXC...
A piecewise regression approach was used to objectively quantify barotrauma injury thresholds in two physoclistous species, Murray cod Maccullochella peelii and silver perch Bidyanus bidyanus, following simulated infrastructure passage a barometric chamber. The probability of injuries such as swimbladder rupture, exophthalmia haemorrhage, emphysema various organs increased the ratio between lowest exposure pressure acclimation (ratio change, R(NE:A) ) reduced. relationship typically...
ABSTRACT Egg and larval fish that drift downstream are likely to encounter river infrastructure consequently rapid decompression, which may result in significant injury. Pressure-related injury (or barotrauma) has been shown juvenile fishes when pressure falls sufficiently below at the acclimated. There is a presumption eggs larvae be least as, if not more, susceptible barotrauma because they far less-developed more fragile than juveniles, but studies date report inconsistent results none...
A multiplex reverse transcription quantitative PCR (RT-qPCR)-based method was designed for the simultaneous detection of different SARS-CoV-2 genes. In this study, we used three target genes encoding nucleocapsid 1 and 3 (N1, N3), spike (S) proteins, all commonly in human environmental samples. The performance assay, compared to single assay assessed standard calibration curve, required absolute quantification, then, real samples detect SARS-CoV-2. For latter, four were collected at a local...
Estrogenic compounds are widely released to surface waters and may cause adverse effects sensitive aquatic species. Three hormones, estrone, 17β-estradiol 17α-ethinylestradiol, of particular concern as they bioactive at very low concentrations. Current analytical methods not all enough for monitoring these substances in water do cover mixture effects. Bioassays could complement chemical analysis since detect the overall effect complex mixtures. Here, four mixtures two hormone were prepared...
Wastewater treatment plants (WWTPs) collect wastewater from various sources and use different processes to reduce the load of pollutants in environment. Since removal many chemical bacteria by WWTPs is incomplete, they constitute a potential source contaminants. The continuous release contaminants through WWTP effluents can compromise health aquatic ecosystems, even if occur at very low concentrations. main objective this work was characterize, over period four months, steps starting income...
This study aimed to investigate the bacterial diversity and background level of antibiotic resistance in two freshwater ecosystems with low anthropogenic impact order evaluate presence natural antimicrobial these areas its potential spread downstream. Water samples from a pre-Alpine an Apennine river (Variola Tiber, respectively) were collected three different sampling campaigns was assessed by 16S sequencing, while bacteria resistant five antibiotics screened using culturable approach....
Abstract. The electrical conductivity of pig slurry suggests that addition this waste to soils in arid and semi‐arid areas could cause salinization. Changes soluble salt concentration two calcareous indicated a salinity risk after 24 months at rates 400 m 2 /ha/yr or more. Salinity increased with soil water‐holding capacity. Water‐soluble potassium concentrations showed greater increase than other cations the because large amount present slurry. proportion depended on soil's cation exchange...
Abstract The Lower Mekong Basin is facing unprecedented threats to fish diversity from hydropower development. There increasing pressure on developers and construction authorities design solutions improve survival through turbines, thus protecting the resources in regions being developed for hydropower. A hydraulic characteristic of turbines with known fisheries impacts fluid shear stress. Elevated stress occurs where rapidly flowing water passes near spillways, screens within turbine draft...
Egg and larval fish drifting downstream are likely to encounter river infrastructure leading mortality. Elevated fluid shear is one cause. To confirm this determine tolerable strain rates resulting from shear, egg larvae of three Australian species were exposed a high-velocity, submerged jet in laboratory flume. Mortality was modelled over broad range rates, allowing critical thresholds be estimated. Eggs very susceptible mortality at low 100% golden silver perch died once rate exceeded 629...
Abstract Elevated expression of cytochrome P4501A (CYP1A) is an established biomarker for exposition to a wide range toxicants, particularly dioxin and structurally similar compounds. Expression CYP1A usually analyzed in internal organs, which involves dissection the specimen. To avoid unnecessary animal killing, we present here alternative method based on monitoring fish scales. Using β‐naphthoflavone (BNF; 50 mg/kg body wt, intraperitoneal injection) as inducer goldfish ( Carassius auratus...
