Unlike soybeans, lupin seeds do not contain trypsin inhibitors; they don’t need heat treatment to be used in feed. Lupin has a high attachment of beans. It is drought-resistant, adapted to environmental conditions with insufficient moisture. The formation of seedlings is a critical period in the ontogeny of lupin, preceding sprouting. At this time, parameters of seedlings such as the speed and vigor, density, distribution uniformity on the soil surface are determined. The objective is to determine the dynamic characteristics of seedlings of white and blue lupin seeds by alterations in the wet and dry weight of the seedling and its individual organs in laboratory and field experiments. In the laboratory experiments, seeds of white and blue lupins were germinated on sifted and calcined sand, moistened to 80% of the total moisture capacity at 20 oC. On the 4th and 7th days, the wet and dry weight per 100 seedlings, morphological alterations in the seedling bodies and their mass were determined, as well as the expenditure of seed reserve nutrients for the formation of seedlings was calculated. In field experiment, the same parameters of seedlings were determined, considering their laboratory germination (according to the number of viable seeds per 1 m row). The formation features of seedlings of white and blue lupins in laboratory and field experiments have been studied. The certain features influencing the parameters of seedlings in field during the critical \"sowing-seedlings” period have been determined.","PeriodicalId":9640,"journal":{"name":"caspian journal of environmental sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46517665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two main sources of pollution on the territory of cities: industry and motor transport. Currently, with a significant reduction in industrial production, road transport is one of the main sources of environmental pollution. The largest amount (more than 200) of air pollutants is provided by gasoline carburetor engines: carbon monoxide, nitrogen oxide, unburned hydrocarbons. When 1 liter of gasoline is burned, 200 - 400 mg of lead is released, thus, one passenger car emits up to 1 kg of lead into the city atmosphere per year. Diesel engines pollute the atmosphere with soot, sulfur compounds, benzo pyrene. According to American geochemists, in cities more often than in rural areas, we observe cloudy weather, more rain and less snow. Atmospheric dust in cities is 100 times more, exhaust gases, 5-25 times more than in agricultural landscapes. All this affects the health of the population. The favorable factor is that the main streets with heavy traffic are located on the watersheds, in the upper part of the city, where conditions are better for dispersing impurities. However, on streets descending into depressions, where air stagnation and surface inversions are more likely, and where uphill vehicle emissions increase, air pollution is upraised.","PeriodicalId":9640,"journal":{"name":"caspian journal of environmental sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44292960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These include heavy metals, radioactive materials, inorganic chemicals, organic chemicals, disinfectants, and disinfectant additives. Common methods for removing these contaminants from aqueous solutions include chemical precipitation, membrane processes, ion exchange processes, biological processes, adsorption, and chemical reactions. Each of these methods has limitations in application. Many studies have been performed on the use of graphene in filters. Graphite oxide (GO) platelets were prepared using a modified Hummers method. By employing GO platelets, GO/poly (acrylic acid – maleic acid) superabsorbent composites were synthesized by a free radical polymerization of acrylic acid and maleic acid as a monomer, using N, N -methylenebisacrylamide as cross-linker and ammonium persulfate as initiator. The well-dispersed GO platelets in the polymer networks result in a significant improvement in absorbencies in distilled water solutions. The superabsorbent nanocomposite also exhibits a superior water-retention ability compared with the control under the same conditions. GO/P(AA-MA) composite was investigated using felid emission scanning electron microscopy (FE-SEM) and Fourier transform infrared (FTIR); GO/P (AA-MA) composite is a highly effective absorbent of crystal violet (CV) and can be used to remove CV from aqueous solution. The kinetics of dye adsorption has been studied in terms of pseudo-first-order and pseudo-second-order rate expression. The results indicated that the adsorption process followed two models and demonstrated that intraparticle diffusion plays a significant role in the adsorption mechanism.","PeriodicalId":9640,"journal":{"name":"caspian journal of environmental sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45164429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two concentrations (10 and 20 ppm) were selected for lead respectively in one week. Biochemical markers such as acetylcholinesterase, superoxide dismutase and catalase were used to assess lead exposure cytotoxic effects, while lead-induced DNA damage was used to determine the effect of lead on molecular level. Fish samples were treated with two selected concentrations of lead solution (10 and 20 ppm) for one-week duration, as exposure period, to detect the impacts of lead exposure on this species. Various biochemical markers such as acetylcholinesterase, superoxide dismutase, and catalase were applied to determine the cytotoxic impacts of lead exposure at the cellular level, while the lead-induced DNA damages were identified to reveal the influences of lead exposure at the molecular level. The results represent that the highest concentration of lead solution (20 ppm) had more effects on the antioxidant enzymes activities such as superoxide dismutase (SOD) level (655.17 ± 21.76 mg U-1) followed by acetyl cholinesterase and catalase (655.17 ± 21.76 U L-1 and 87.93 ± 7.22 mg U-1) respectively. The DNA damages were estimated by the Comet assay technique and the highest level of DNA damages were documented when lead concentration was 20 ppm using different parameters of Comet assay technique such as Comet length, tail length, and tail moment (4021 ± 56.11 µL, 523 ± 55.80 µL, and 91.208 ± 9.45 µL respectively). Therefore, this study confirms that the exposure to high lead concentrations would cause harmful effects on aquatic organisms at both cellular and molecular levels.","PeriodicalId":9640,"journal":{"name":"caspian journal of environmental sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43975913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physicochemical characteristics of the lake water classify it as eutrophic, polluted, with a low oxygen content, but a high content of organic matter and phosphates. In parallel, some studies were carried out on its zooplankton community. Karasikha Lake is the habitat of 70 species of planktonic rotifers and crustaceans identified. Based on the number of species, rotifers predominated and their largest number belonged to Brachionidae family. On average 3-4 species were dominant, as indicators of eutrophic and polluted waters. However, with a relatively high species richness of zooplankton, the community has low quantitative indicators. The low oxygen content in the water column makes zooplankton concentrate mainly in the epilimnion layer (up to 2-3 m in depth). The lowest quantitative indicators of zooplankton are characteristic of the under-ice period, which is also associated with a lack of oxygen in the water. The community is dominated by indicators of dirty waters. The structure of zooplankton communities is typical of highly polluted lakes. Indices based on the taxonomic structure of zooplankton classify the reservoir as highly eutrophic and even hypertrophic.","PeriodicalId":9640,"journal":{"name":"caspian journal of environmental sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44269192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
