Arsenic is introduced into soil and water through geological (weathering of rocks and minerals) and anthropogenic pathways (mining, pesticides, fertilizers, timber treatment etc). Irrigation of agricultural land with As-contaminated groundwater or wastewater, particularly in India, Bangladesh and South-East Asia resulted in the accumulation of arsenic in both soils and plants posing risks to soil ecosystems and human health. Arsenic in soil and water exists in a different valence state, but predominantly as toxic As(III) and less toxic As(V) form. Arsenic toxicity is one of the most challenging problems in drinking water, as well as food crops (Samal et al., 2021). With greater public awareness of arsenic poisoning in animals and human nutrition, there has been growing interest in remediation technologies for mitigating As-contaminated ecosystems. Remediation of As-contaminated soil improves physical, chemical and biological approaches that may achieve either partial/complete removal of arsenic from soil and water. Many technologies like bioremediation, phytoremediation, soil mixing, soil washing, soil capping, filtration, adsorption and immobilization are used for arsenic removal from soil and water. Phytoremediation is a bioremediation process that uses various types of plants to remove, transfer, stabilize, and/or destroy contaminants in the soil and groundwater. But most of the arsenic still remains in the environment and there is always a risk of leaching caused by changes in the environmental conditions. Integrated approach involving a combination of physical, chemical and biological technologies is needed for the successful and effective management of As-contaminated environment.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83900105","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}

The primary screening was done to screen the potential of these isolates for their enzymatic potentials on selective media. The 57 promising bacterial isolates were found to have enzymatic potentials for both gelatinase and protease. The screened isolates were subjected to secondary screening, amongst which five isolates showed maximum production of both gelatinase and protease. These five isolates viz.

The maximum OM during the migration study was 4.24 mg/dm2 for tomato ketchup and 3.48 mg/dm2 for guava jelly, both of which were within the standards-permitted limits. Total Soluble Solids (TSS) and pH gradually increased whereas ascorbic acid was reduced in tomato ketchup during storage. The total sugar of jelly increased during the storage study from 46.92 to 66.10 %. The findings revealed that the OM rate was well within the specifications of the Bureau of Indian Standards (BIS) while the quality parameters of TSS, pH, and total sugar were altered after and during the three months of storage study.

Currently the most important constraint for apple producers is that its management becomes difficult due to resurgence problems and also their high fecundity rate, complex life cycle. So our motive to study biology of Aphis pomi is to find a better management strategy as biological study of insect is one of the key factor for its management. In the present study the biological parameters evaluated were duration and survival% of nymphal instars, daily and total fecundity and adult longevity by various methods under laboratory conditions. Also the data on pre-oviposition, oviposition and post-oviposition was recorded. We found that duration of total nymphal period, pre-ovipositional period, ovipositional period, post ovipositional period and total life period varied from 13.5-15.5 (14.52±0.070), 10.3-12.5 (14.52±0.07), 10- 20 (13.4±0.65), 2.0-3.0 (2.4±0.17), and 22-35 (30.28±1.51) days respectively.

The Maniyari River, which flows through the reserve, is known as its life line. It originates from the core zone (Sihawal sagar) of ATR and merges in the Seonath River of the Mahanadi Basin. It flows about 105 km through Mungeli and Bilaspur districts. This river supplies its catchment area with water seasonally (6-8 months) and flows more than half of its length (about 60 km) within the protected area. Its catchment area has a rich biodiversity of tree species such as Shorea robusta, Terminalia tomentosa, Diospyros melanoxylon, Adina cordifolia, Pterocarpus marsupium, Madhuca indica, Anogeissus latifolia, Dendrocalamus strictus etc. A geospatial analysis was performed to understand the course of the Maniyari River within the ATR area over a fourteen year period between 2000 and 2013. Imagery from Indian Remote Sensing (IRS) satellite 1D and P6 for years 2000, 2004, 2008, 2010 and 2013 and Survey of India toposheets were analyzed to examine the changes in planform characteristics of the Maniyari River. The meander shift of the river was delineated considering the R1 (11.61 km), R2 (11.19 km), R3 (5.33 km) and R4 (5.02 km) reach’s respectively. Sinuosity Index (SI) for different reaches was calculated and evaluated. The SI ranged from 1.40 to 1.63, 1.20 to 1.29, 1.17 to 1.37, and 1.20 to 1.49 in R1, R2, R3 and R4 respectively and the magnitude of the shift was analyzed with the year 2000 as the base year. The overall SI for all the reach’s ranges between 1.30 and 1.36. The present study will be helpful in understanding the river dynamics as well as to maintaining the flow of the Maniyari River and preventing bank line erosion. The study will be helpful for the conservation of river flow and its tributaries in the ATR area in Central India.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88504679","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}

South American tomato leaf miner, Tuta absoluta has become major pest in tomato growing areas causing 50-60% damage. Even though pest damage starts from seedling stage, damage is not noticed by farmers till fruiting stage due to the pest feeding habit, and spraying chemicals repeatedly at this stage is of no use. Moreover, it causes environmental pollution and pesticide residual effects on consumers. Hence, an on-farm trial on integrated management of the Tuta absoluta was conducted during Rabi, 2020-21. The IPM practices included were installation of pheromone traps @ 25 per hectare; spraying neem oil @ 5 ml/l, twice @20 and 40 DAT and need based chemical sprays. In IPM plots, pest damage was low in crop grown under single row planting i.e., 9% followed by double row planting i.e., 12.6% whereas in farmers practice it was 21.5% and 24.3% in single row planting and double row planting respectively in crop planted during December, 2020. Crop planted during January suffered more than December planted cropi.e., in IPM plots it was 12.5% & 15.5% whereas in farmers practice it was 27.6 and 31.2% in single row planting and double row planting respectively. In December planted crop, Fruit yield of 54.2t/ha and 52.8t/ha was recorded in IPM and farmers practice respectively.
