American Journal of Environment Studies https://ajpojournals.org/journals/index.php/AJES American Journal of Environment Studies is internationally peer reviewed journal by AJPO. The journal aims at promoting understanding of vital environmental concerns, seek publication of major behavior of upcoming contaminant, effect of human activities on environment, human exposure to environment contamination, its effect and control. The journal being of high factor is also a hub for all those who seek to make the earth a better place. en-US admin@ajpojournals.org (Journal Admin) support@ajpojournals.org (Journal Support) Wed, 02 Nov 2022 20:31:28 +0300 OJS 3.2.1.1 http://blogs.law.harvard.edu/tech/rss 60 Urban Solid Waste Management https://ajpojournals.org/journals/index.php/AJES/article/view/1268 <p>This review article creates awareness among people to manage solid waste by using different methods because if these wastes are not properly disposed then different environmental problems are created. Books and journals were utterly examined for this study. Waste is by product which is produced by human activities through different resources. Population growth, urbanization and exceeding economy are factors due to which its management is a challenge. Incineration, composting, pyrolysis, gasification and landfilling are different procedures which are used to manage wastes. Current strategies for treatment of solid waste are used to reduce or to recover solid waste, useful products are produced by waste through these processes which are then used in different ways.</p> <p><em>&nbsp;</em></p> Saira Javed, Dr. Faheem Malik Copyright (c) 2022 American Journal of Environment Studies https://ajpojournals.org/journals/index.php/AJES/article/view/1268 Wed, 02 Nov 2022 00:00:00 +0300 Effect of Hyperthermia on Photosynthetic Pigments of Some Selected Fern Taxa of Sitamata Wild Life Sanctuary, Rajasthan https://ajpojournals.org/journals/index.php/AJES/article/view/1266 <p>Rajasthan, the state is situated in the north western part of India and covers as area of 3, 42, 274 sq.km. Despite the hostile climatic conditions of the state, pteridophytes which otherwise known as shade and moisture loving plants. Sitamata wild life sanctuary is located at southwest region of Rajasthan. Different species of pteridophytes in this region exhibit significant variation in thermal stability of their photosynthetic pigments of some pteridophytic flora of Sitamata wild life sanctuary, Rajasthan. Studies reveal that total chlorophyll contents are maximum in <em>Ceratopteris thallictroides </em>and<em> Selaginella repanda </em>and minimum in <em>Ampelopteris prolifera</em>. The other species range between these two. Total carotenoid contents were found maximum in <em>Cheilanthes bicolor</em> and minimum in <em>Selaginella repanda.</em> These observations suggest that species with greater resistance to drought possess higher quantity of carotenoids and show lesser degradation in their chlorophyll pigments during stress conditions. Thus, <em>Ampelopteris prolifera</em><em>, Cheilanthes bicolor </em>and<em> Christella dentata </em>are most resistant to heat and drought conditions while<em> A. capillus-veneris, Ceratopteris thallictroides </em>and <em>Selaginella repanda </em>are the least resistant taxa to heat and drought conditions.</p> Sharma Vinay, Bhawnani Jaya Copyright (c) 2022 American Journal of Environment Studies https://ajpojournals.org/journals/index.php/AJES/article/view/1266 Wed, 02 Nov 2022 00:00:00 +0300
