    The COVID‐19 pandemic has created a global emergency crisis in terms of socio‐economic‐ environmental challenges. Such crisis in Iran have also affected the issue of waste, change its amount and composition, pollution rate and led to changes in waste management including collection and different disposal methods. This is analytical descriptive research which is based on the Tehran Waste Management Organization actions, various institutions report and other available resources. At the present study, after reviewing the experiences of different countries and organizations like United Nation, World Health Organisation, The international Solid Waste Association investigating the managerial compliance has been formed. After reviewing the current situation, considering the priorities of the International Solid Waste Association, the Waste Management Organization has identified three priorities for waste management during the pandemic of COVID‐19 which consist of ensure the continuity of the service, adjusting recycling services and the last ensure safe collection, disposal and treatment of healthecare waste. The first step ensures the continuity of the services and also health and safety measures for waste workers and contingency plans. The principle behid the second priorty is adjusting recycling services and the last ensure safe collection for workers and people and the last one is about ensure safe collection, disposal and treatment of healthecare waste action plans. Finally, according to the experiences gained and the actions of the Tehran Waste Management Organization, suggestions have been made to improve the conditions of waste management during the pandemic of COVID‐19.

    Mangrove ecosystem in Peninsular Malaysia is endangered from human encroachment, shipping/sportive activities, wood harvesting and industrial pollution. This study was conducted to determine the presence of certain toxic heavy metals such as Chromium (Cr), Manganese (Mn), Arsenic (As), Zinc (Zn) and Lead (Pb) in surface sediments of the mangrove. The sampling locations were carefully selected to represent various types of anthropogenic inputs. The metals concentrations were analyzed using inductively‐couple plasma mass spectrometer (ICPMS). The range of metal concentrations was as follows: Cr (14.31 – 132.95) µg/g., Mn (11.34 – 996.04) µg/g., As (7.31 – 138.82) µg/g., Zn (59.33 – 343.56) µg/g. and Pb (27.12 – 151.15) µg/g. These were compared with international guidelines and strikingly, the levels at most sites exceeded the prescribed levels. Compared to previous studies in Malaysia, Mn, Zn and Pb pollution in mangroves increased over the years. The geoaccumulation index revealed that most of the mangrove is strongly polluted with As, unpolluted to moderately polluted with Cr and Mn, moderately polluted with Zn and moderately to strongly polluted with Pb. Therefore, mangrove ecosystems need to be monitored regularly to understand the extent of pollution with increasing population. Finally, this study can be considered as a baseline study on heavy metal pollution in mangrove sediments in Malaysia.

    Transportation has an effective role in the development and welfare of societies and is a key to economic development. Major sources of air pollutant in the oil and gas industry are: aromatic gases, vapors and dust coming out of the tower, flue gases including NH3, SOX, NOX, O2, CO2, CO. The research method is to review the life cycle assessment that provides estimating the cumulative environmental effects of all stages of the bitumen production life cycle. The results of the literature review showed that the life cycle assessment of bitumen production can be done in different ways. It can also help the organization that compare products or processes and pay attention to environmental factors in material selection. In addition, it can be useful and effective in policy‐making by helping to develop government rules with respect to the consumption of environmental resources and diffusions. The results show that in this industry, in order to move towards the development of low carbon industry, items such as observing the principles R3 (recycling, reuse, reduce), wastewater management, production of environmentally friendly product (green), use of low Power consumption systems is essential.

    There are limited studies in Malaysia on the effects of socio‐demographic, cultural, and prominent five personality traits on waste prevention behaviors (WPBs). Study conducted to determine the relationship between those traits, and WPBs among the Chinese community in Sepang district, Selangor state. Malaysia consists of three ethnic communities, namely, Malays, Chinese, and Indians. The Chinese lead most of the pro‐ environmental movements in Malaysia, which need to be scientifically substantiated. Results were obtained through a questionnaire distributed randomly to 431 Chinese respondents. Gratifying our assumption, 69.6% of respondents possessed a decent medium‐level WPBs, and 12.8% had a high level of WPB. Interestingly, gender, education level, and income influenced WPBs. Linear regression analysis revealed that cultural traits rather than well‐known prominent five personality traits significantly impacted on WPBs in this population.

    Our planet is on the verge of serious destruction in the conflict of national and racial selfishness as well as the recklessness of wealthy politicians; and the globalization phenomenon has accelerated the issue in various economic, cultural, and political dimensions. In addition, developing countries have easily succumbed to this phenomenon because of their lack of a clear strategy in various fields including the environment, sustainable economy, and preservation of indigenous‐local culture, which may be due to their knowledge, technology, and economic inabilities. Indeed, it should be noted that globalization (distribution) should be considered fundamentally inappropriate, but how to use it in time and space is important. The research is of library type and is based on scientific observations of human phenomena and natural features of different regions of Iran, north, center, west and northwest. The present study is a library type research based on scientific observations of human phenomena and the natural features of different regions in the northern, center, west, and northwest of Iran. The research methodology is structural‐functional and systemic. Research shows that the loss of indigenous cultures (cultural unification) increases materialism. Also, studies conducted in different countries in relation to environmental pollution and international trade shows a close relationship between these parameters, and that environmental degradation in deprived countries and areas is more than other regions.

    So far, the concept of quality of life and its criteria have been studied from different perspectives. Also,streets have been the main element of the city structure from the beginning and they can play a role as a human‐centered urban space to increase liveability and life quality. With the arrival of cars in urban spaces, man and his needs were gradually forgotten. human senses and his perception lost its place at designing process. Today, we are faced with spaces of anonymity that leave no image in the mind except heavy traffic and noise pollution. Most streets have only a passin and access function, and activities such as sitting, watching and sitting in the urban space have disappeared. This research seeks to improve the quality of life with emphasis on liveable streets and public spaces of District 9 of Tehran. For this purpose, after identifying and determining the effective dimensions and indicators, the selected criteria in the environmental, economic, social, cultural and physical dimensions in the two sub region 1 and 2 have been studied. A questionnaire prepared for this purpose was distributed among the citizens of these areas and examined separately. After extracting 4 dimensions and 13 sub‐criteria effective in the research to recognize the current situation and study the problems, we can suggest appropriate solutionsto improve the liveability of areas, streets and cities

    Failure of proper household waste management causally linked to public attitudes and behaviors. The main objectives of this study are to analyze the awareness level of households and their perception towards recycling and composting waste. Four hundred seven respondents from Selayang, Malaysia, have participated in this questionnaire, revealing their demographic details, self‐measured level of awareness, and their perception of recycling and composting. The collected data were analyzed using descriptive analysis and Pearson correlation in SPSS software. The results showed that young, less educated Malay males have a higher awareness levels on recycling, while young, higher educated single‐ and lower‐income people have higher awareness levels in composting. The overall result shows that the awareness level and knowledge on recycling and composting are high among Selayang area residents. The awareness level and knowledge could be effectively applied in programs aiming at behavioral modification and attitude change in communities towards waste management.

    Dates have a high tolerance for harsh environmental conditions. The purpose of this study is to investigate the planting of date trees in reducing environmental hazards. The research method is library and applied. The results show that this product has a special role in preventing desert development. In the discussion of food security, attention has been paid to maintaining environmental sustainability. The palm tree has primarily food and economic benefits and secondly is effective in reducing many environmental problems in the region such as pollution, desertification and global warming. Date palm is suitable for creating plant areas resistant to desertification. This will help solve the environmental problems of the Arab countries. The leaves contain many nutrients and organic matter that can be converted to compost. Discussion and Conclusion The presence of palm trees in the country has created direct and indirect job opportunities that inevitably if the water salinity situation is not addressed and there is no solution for processing and packaging plants of dates, lack of cooperation between the government and investors, the date industry suffers It loses.
