[Ab] Resumo:There are presented results of the cytome analysis of epithelium of buccal mucosa in 167 children aged of 5-7 years, permanently residing in the city of Magnitogorsk and visiting municipal kindergartens. Frequencies of the main indices of genotoxic and toxic effects were: cells with micronuclei - 0.29±0.04 %, with protrusions ofnuclei - 1.47±0.17 %, with double nuclei -1.96±0.13 %, with two nuclei - 3,28±0,16 %, with perinuclear vacuole - 9.66±0.86 %, with pycnosis of nucleus - 4.60±0.31 per 1000 cells, with karyorrhexis - 0.86±0.15per 1000 cells, with lysis of nucleus - 54.34±3.90 per 1000 cells, the condensed chromatin cells - 10.59±1.35 per 1000 cells. Most of these indices didn't differ from the same detected earlier in buccal epithelial cells from children of the same age in Moscow, except cells with perinuclear vacuole, which frequency in Moscow cohort was twice higher. Frequencies of cells with these anomalies were associated with the content of 19 out of 326 revealed components of contamination of the total-winter snow samples, taken on the territories of the kindergartens, which were visited by examined children. There was shown lack of differences from basic values of main indices previously establishedfor the children of the same age in Moscow, with the exception of cells with perinuclear vacuole, the rate of which in Moscow was twice higher. There were revealed confounding factors associated with test indices: gender of the child, the annual number of acute respiratory diseases, health group, income per one person in family, alcohol intake by parents.

[Ab] Resumo:Hydrotechnical facilities have significant environmental and health imyacts. Results of a hygienic assessment of the condition of environmental objects in the area of the yrojected Nizhny Novgorod low-head water ylant develoyment showed that the both air and water pollution level in decentralized water supply sources in Balakhna and Gorodets are lower than in the city of Nizhny Novgorod, and those of the water in the water supply network are higher than in the reference area. A cross-sectional study has revealed in the main grouf (Gorodets, Zavolzhye and Balakhna) the rate of morbidity of nervous system and cardiovascular diseases to be higher than in the reference group (Nizhny Novgorod), with cardiovascular diseases being the largest contributor to the overall grevalence rate in the groug under analysis; and digestive system diseases, in the reference group. The study has no revealed direct correlation between morbidity rate in children and adults and the studied factors. However, a direct relationship has been found between the prevalence rate of endocrine diseases in children and the quality of water in the water supply network in Balakhna District (p<0.007); also, there's a correlation between the morbidity rate of digestive diseases and air pollution and water quality in the water supply network (p<0.009). In the Gorodets District, the same situation has been revealed: the morbidity rate of endocrine diseases in children depends on quality of water from the water supply network (p<0.049); the prevalence rate of digestive diseases, on air pollution and water quality in the water supply network (p<0.048). In the same region in adults the prevalence rate of the nervous system diseases, digestive diseases and diseases of the skin and subcutaneous tissue depends on air pollution and pollution of water in the water supply network (p<0.011, p<0.01 and p<0.02, respectively).

[Ab] Resumo:Exploration and development of mineral deposits in the Transurals of the Republic of Bashkortostan are accompanied by a comprehensive environmental impact. Ones of the most vulnerable elements of the landscape are the surface water bodies used for fishery purposes, recreation and household needs of the population. Extraction and processing of ores lead to the contamination of aquatic ecosystems by heavy metals (HM), which by passing into a pond, can actively be involved in the cycling of matter and migrate via food chains to the human under the consumption of fish products. Possessing by cumulative properties, HM can express mutagenic, teratogenic and carcinogenic properties. The aim of research was the study of the impact of mining facilities on the content of the priority HM in the components of river ecosystems in the Transurals of the Republic of Bashkortostan and the development of a complex of preventive measures on the improvement of the human environment. There was studied the content of Zn, Cu and Cd in the water, bottom sediments and phytomass of Elodea canadensis Michx. The measurements of mass concentrations of metals were performed by stripping voltammetry with the use of the STA device. The results showed that for the cross-sections there is typical the following descending series of elements in the river components: Zn > Cu > Cd. In water samples there is observed the exceedance of standards for water bodies of potable, cultural and community water use and fishery basins. The concentration of zinc varies in the range of 0.016-5.24 mg/dm; copper - 0.0024-0.095 mg/dm; cadmium - 0.0001-0.019 mg/dm. In bottom sediments, in general, the content of metals in comparison with control plots is increased to the tenfold value. The meaning of mobile forms of zinc in the ground varies in the range of 0.81-9.62 mg/kg; copper - 0.12-18.69 mg/kg; cadmium - 0.00013-0.092 mg/kg. The zinc concentration in above-ground phytomass of Elodea canadensis compared to control increases by 2-3.5 times, copper - 4-8 times, cadmium - 2-7 times. Univariate analysis of variance confirmed the accuracy of the impact of the degree of contamination on the accumulation of metals by Elodea canadensis. The results testify to the potential danger to health of water bodies of the region's population.

[Ab] Resumo:This paper deals with the use of a raceway pond reactor (RPR) as an alternative photoreactor for solar photocatalytic applications. Raceway pond reactors are common low-cost reactors which can treat large volumes of water. The experiments were carried out with TiO in the agriculture effluent spiked with Chlorpyrifos (CPF) at circumneutral pH. The Response Surface Methodology (RSM) was used to find the optimum process parameters to maximize CPF oxidation from the mathematical model equations developed in this study using R software. By ANOVA, p-value of lack of fit > 0.05 indicated that, the equation was well-fitted. The theoretical efficiency of CPF removal, under the optimum oxidation conditions with UV solar energy of around 697 ± 5.33 lux, was 84.01%, which is in close agreement with the mean experimental value (80 ± 1.42%) confirming that the response model was suitable for the optimization. As far as the authors know, this is the first study of CPF removal using RPR in agriculture runoff at circumneutral pH.

[Ti] Título:Effects of Water Addition to Prevent Deterioration of Soybean Oil by Calcium Silicate Adsorbent.

[Ab] Resumo:In this study, we prepared calcium silicate at different molar ratios (Ca:Si=1:3, 1:6, and 1:9 refer to CAS-30S, CAS-60S, and CAS-90S, respectively) with water addition. The adsorbent characteristics (specific surface area, pore volume, mean pore diameter, and elemental analysis) were measured and the effect of water addition on the adsorbent surface for the prevention of deterioration was evaluated. In addition, the deterioration of soybean oil (SO) subjected to heating and aeration was investigated based on the acid value (AV) and carbonyl value (CV). The specific surface area increased in the order CAS-60S (160.51 m /g) < CAS-30S (182.61 m /g) < CAS-90S (204.19 m /g). Deterioration of SO could be induced by heating and aeration with AV and CV of 1.4 mg/g and 102.9 µmol/g, respectively. The adsorbent (CAS-30S and CAS-90S) with water addition (25% and 50%) was found to decrease the AV, indicating that a small amount of water addition to adsorbent surface is important for the decreasing of AV. In addition, the correlation between the decrease in AV and the specific surface area is strongly positive (R value: 0.968). The adsorption mechanism is thought to involve interactions between the polar compounds (free fatty acids) in the SO (nonaqueous phase) and the water layer (containing calcium ions released from the adsorbent) on the adsorbent surface. In summary, the data obtained in this study provide useful information for preventing the deterioration of SO and prolonging the oil life cycle.

[Ab] Resumo:Assessment of water quality status of 7 sites of Kavvayi Wetland in northern Kerala (India) was carried out. The physico-chemical, bacteriological and biological parameters were monitored during pre-monsoon, monsoon and post-monsoon seasons. Canadian Council of Ministers of the Environment (CCME) water quality index of the Kavvayi Lake samples ranged from 43.99-44.77; indicating that water quality was threatened or impaired. The poor water quality status might be due to dumping of wastes from municipal and domestic sources and agricultural runoff. Biological water quality criteria (BWQC) determined for wetland revealed that stations such as mixing point of Kariangode River into Kavvayi Lake and Kottikkadavu was moderately polluted in pre-monsoon and post- monsoon seasons. Mixing point of Nileswar River into Kavvayi Lake was moderately polluted in pre-monsoon season. Both calculated indices suggest that quality of lake was found to be influenced by anthropogenic activities such as unscientific tourism and infrastructure development, land encroachment, sand mining, pollution etc. The study was carried out as part of a programme, which aimed to conserve Kavvayi wetland because of its unique ecological and environmental characteristics.

[Ab] Resumo:Abundance and seasonal trophodynamics. (specific growth rate, daily production, and grazing mortality) of the major picophytoplankton components, Synechococcus cyanobacteria (Syn) and picoeukary- otes (Pico-E), were studied at three stations in Sevastopol Bay and adjacent coastal waters (the Black Sea) in 2014 by flow cytometry and the dilution method. Pico- E abundance was shown to increase along the nutrient and pollution gradient from the coastal waters outside the bay (annual average of 7.3 ± 5.4 x 103 cells mL⁻¹) to the eastern corner of the bay (28.7 ± 11.4 x 103 cells mL⁻¹), while no relation was found between the water pollution status.and Syn abundance (9.9 ± 8.7 x 10³ cells mL⁻¹, at all the stations, n=27). Matter flows through the communities (daily production for Syn and Pico-E 0-16.6 and 0-19.3 µg C L- day⁻¹, respec- tively; grazing mortality for Syn and PicoE 0-3.6 and 0-21.2 µg C L⁻¹ day⁻¹, respectively) were comparable to or even exceeded their biomass stocks (<0.05-6.8 and 0.9-26.5 µg C L- for Syn and PicoE, respectively), indicating high biomass turnover rates. The highest flow-to-stock ratio (up to 6 for Syn) and,a significant imbalance between daily production (P) and grazing mortality (G) were observed in the most polluted and eu- trophicated waters of the bay in spring (Pico-E: P/G <.1) and late summer (Syn: P/G > 1). Black River inflow to the bay was hypothesized to be among the mechanisms maintaining.this pronounced and long-term im- balance in the open system without any negative consequences for the picophytoplankton assemlages.

[Ab] Resumo:Fecal contamination of water poses a significant risk to public health due to the potential presence of pathogens, including enteric viruses. Therefore, sensitive, reliable and easy to use methods for the concentration, detection and quantification of microorganisms associated with the safety and quality of water are needed. In this study, we performed a field evaluation of an anion exchange resin-based method to concentrate male-specific (F+) RNA coliphages (FRNA), fecal indicator organisms, from diverse environmental waters that were suspected to be contaminated with feces. In this system, FRNA coliphages are adsorbed to anion exchange resin and direct nucleic acid isolation is performed, yielding a sample amenable to real-time reverse transcriptase (RT)-PCR detection. Matrix-dependent inhibition of this method was evaluated using known quantities of spiked FRNA coliphages belonging to four genogroups (GI, GII, GII and GIV). RT-PCR-based detection was successful in 97%, 72%, 85% and 98% of the samples spiked (10 pfu/l) with GI, GII, GIII and GIV, respectively. Differential FRNA coliphage genogroup detection was linked to inhibitors that altered RT-PCR assay efficiency. No association between inhibition and the physicochemical properties of the water samples was apparent. Additionally, the anion exchange resin method facilitated detection of naturally present FRNA coliphages in 40 of 65 environmental water samples (61.5%), demonstrating the viability of this system to concentrate FRNA coliphages from water.

[Ab] Resumo:Use of groundwater from private wells in households has increased considerably, owing to a better cost/benefit ratio than that of water provided by local utilities for a fee. However, this water is usually untreated, which makes it a vehicle for diseases. Thus, monitoring this water is necessary to ensure its integrity and quality. We aimed to evaluate the physical, chemical, and microbiological parameters of untreated groundwater drawn from different types of wells, and the antimicrobial susceptibility profile of the bacteria isolated from this water. Wellwater samples were collected in two Brazilian cities. Although physical and chemical parameters of the water were suitable for drinking, was detected in 33% of the samples. contaminated 65% of dug wells and 10.25% of drilled wells. Many bacteria isolated were resistant to multiple antibacterial agents, including ß-lactams. Microbial contamination of this water was related to the well depth, and was more common in dug wells, making this water unfit for human consumption. Consumption of such contaminated and untreated water is a public health concern. Thus, individuals who regularly use such water must be alerted so they may either take preventive measures or connect to the water distribution system operated by local utilities.
