Aridity Impact on the yield and the composition of argan oil (Argania spinosa (L. Skeels))

Research article of Journal of Plant and Environmental Research Aridity Impact on the yield and the composition of argan oil (Argania spinosa (L. Skeels)) Fadma Fahmi *, Saida Tahrouch, Khadija El Mehrach, Abdelhakim Hatimi Laboratory of Plant Biotechnologies, Department of Biology, Faculty of Sciences, University Ibn Zohr, PB 8106, 80000, Agadir, Morocco In this study, we investigated the effect of environmental conditions on the composition in fatty acid and the yield of argan oil of seeds from seven locations following an increase of aridity gradient; Essaouira, Tamanar, Imouzzer, Admine, Ait Baha, Merght and Bouizakarne. Indeed, the analysis of the composition of argan oil showed that the saturated fatty acids varied in the same way in the fruits of the studied plants. Therefore, oleic acid increased with altitude and linoleic acid decreased with aridity. Moreover, no significant differences were found on oil yield of the studied areas. Furthermore, we compared the antioxidant activity of alimentary and cosmetic oil. The results showed that alimentary oil had the highest antioxidant capacity compared to cosmetic oil.

Evaluation and Prediction of Water Quality in the Yangtze River Based on Fuzzy Comprehensive Evaluation Method

Research article of Journal of Plant and Environmental Research Evaluation and Prediction of Water Quality in the Yangtze River Based on Fuzzy Comprehensive Evaluation Method Rui Yan1*, Zihan Hu1, Changwei Wu2, Cheng Li1, Rao Fu1 1College of Hydraulic & Environmental Engineering, China Three Gorges University, Yichang, 443002, China 2College of Law & Public Administration, China Three Gorges University, Yichang, 443002, China Due to the increasingly serious water pollution of the Yangtze river, the discharge of waste water increases year by year, the water pollution problem is very serious, environmental protection is imminent. In this paper, we study the water quality assessment and prediction, based on the analysis of the conditions and data, the fuzzy comprehensive evaluation method to make quantitative analysis, the quality of the water in the Yangtze river and one dimensional water quality model to calculate two kinds of the main sources of pollutants, finally using the linear regression equation to predict the amount of sewage after ten years, and made the solution. Keywords: Equation of linear regression; One dimensional water quality prediction model; Fuzzy comprehensive evaluation ...

The Influence of the Collection of the Waste Classification on the Control of the Domestic Waste Incineration

Review article of Journal of Plant and Environmental Research The Influence of the Collection of the Waste Classification on the Control of the Domestic Waste Incineration Sifang Kong 1,2, Shuang Liu 1*, Rui Zhu 1, Xueqin Cheng 3 1School of Traffic & Environment, Shenzhen Institute of Information Technology, Shenzhen 518172, China. 2Shenzhen Key Laboratory of Circular Economy, Shenzhen Graduate School, Peking University, Shenzhen 518055, China. 3Shenzhen Shanshuile Environmental Technology Co., Ltd. With the continuous development of social economy and the continuous improvement of national living standards in our country, people put forward higher requirements for the quality of living environment around us, and the domestic waste produced in peopleundefineds daily life and the waste treatment produced in the production process have become the key and difficult points that people pay close attention to, and the treatment of domestic waste is related to peopleundefineds health and quality of living environment. Therefore, we should pay attention to the influence of garbage classification collection on the control of domestic waste incineration pollutants. According to my own relevant experience and combined with a wide range of social practice investigation and research, the author discusses the influence of garbage classification and collection on the control of domestic waste incineration pollutants, hoping to provide reference. Keywords: Domestic Waste; Incineration Treatment; Pollutant Control; Influence ...
