The Impact

Abstract While several studies have demonstrated the negative impacts of environmental pollution on population health, in general, few studies have examined the potential differential effects on the health of middle-aged and older populations, i.e. 45 years and older. Given the twin concerns of environmental pollution and population aging in China, this article employed a fixed effects model to infer the impact of environmental pollution on public health with a particular focus on middle-aged and older adults. The analyses were based on data from the 2011–2018 waves of the CHARLS and pollutant data from prefecture-level cities. The results showed that environmental pollution significantly increased the risk of chronic diseases and negatively impacted the health of middle-aged and older adults. Environmental pollution had its greatest negative effect on the health of the elderly, women, urban residents and those with lower incomes than for their counterparts. We further found that the main channels of effect were through reduced physical exercise and an increase in depressive symptoms, and the pollution prevention actions alleviated the health deterioration of environmental pollution for the middle-aged and elderly. It is imperative for the government to urgently reinforce policy's enforcement to decrease air and water pollution, and enhance the ability to circumvent pollution for the lower socioeconomic groups.

The Impact

Green accounting has appeared as an accounting era putting forward the environmental factors as the impact of the business sustainability principle that must be maintained by an entity. This study aims to examine the environmental accounting treatment that has been applied by PT Quarzia Batik Baliand to determine the implementation of Green Accounting in supporting the business continuity of PT Quarzia Batik Bali. Business continuity acts as an economic principle, while environmental sustainability represents the social and environmental impacts generated by economic actors. These two aspects must be reconciled as their crucial nature is long-term. This study is design by using the descriptive-interpretive qualitative analysis method, which is a tool to analyse the information and data collected by interpreting the data based on the actor’s perspective. Systematically, this data processing and analysis method consists of three concurrent flows of analysis activities, such as data collection through interviews and questionnaires, data reduction, and drawing conclusions. The results showed that PT Quarzia Batik Bali has anticipated the environmental pollution due to dyed waste produced from the garment industry using environmentally-friendly dyes and provides several storage tanks to recycle waste so it remains ready to be disposed of on earth. However, in the financial report the processing cost has not been presented separately as an anticipated cost of environmental pollution.

Construction sector which uses cement in its activities causing a release of CO2 into the atmosphere. Currently, all the sectors are viewing seriously in reducing environmental pollution and hazards. In this scenario, the research in industrial wastes such as fly ash, slag, used foundry sand, marble dust, etc., lead to use in construction industries as sustainable materials (SM), thereby contributing to reduction in environmental pollution. This paper reviewed the usage of these SM in the production of micro-concrete is very less when compared with new age conventional concrete, some of the effects of utilization of these SM in micro-concrete are presented. The quantum of research done in micro-concrete is very less, further studies to be done

<p>Urea (CO (NH)<sub>2</sub>) is one of the compositions in making fertilizer. Fertilizer is crucial, especially for plant growth (affecting plant fertility). If a plant had urea fertilizer on the soil, nitrogen in the fertilizer releases quickly, and it will cause environmental pollution. Therefore, many studies want to develop urea fertilizer to be more efficient to use. The purpose of this review is to find the most appropriate method for the efficient use of urea as seen from the material used, the technique used, and the results obtained. This review shows that the most appropriate method is the slow release method with NaOH and fly ash ingredients. Because this method can increase the effective utilization of urea, reduce environmental pollution, and be relatively more straightforward, the raw material is more affordable and spread widely in the market.</p><p> </p>

During incineration of municipal solid waste (MSW), various environmentally harmful elements and heavy metals are liberated either into bottom ash, or carried away with the off-gases and subsequently trapped in fly-ash. If these minor but harmful elements are not properly isolated and immobilized, it can lead to secondary environmental pollution to the air, soil and water. The stricter environmental regulations to be implemented in the near future in the Netherlands require a higher immobilization efficiency of the bottom ash treatment. In the present study, MSW incinerator bottom ash was vitrified at higher temperatures and the slag formed and metal recovered were examined. The behaviour of soluble elements that remain in the slag is evaluated by leaching extraction. The thermodynamics of slag and metal formation is discussed. The results obtained can provide a valuable route to treat the ashes from incinerators, and to make recycling and more efficient utilization of the bottom ash possible.

Developed World

Vehicles, both personal and commercial, have become ubiquitous forms of transportation in the developed world. The auto industry is amidst a technological transformation in identifying alternative sources of energy to power vehicles due to two driving forces: environmental pollution prevention and depletion of fuel resources. This driver for developing “smarter” solutions to create a “smarter planet” is crucial to advancing the science behind electric vehicles (EVs). EVs have been in existence since the mid-19th century, and electric locomotion has been the commonplace in many other vehicle types such as trains. The focus of this chapter is to discuss the feasibility of EVs in smart cities. In particular, the chapter explores the types of EVs, advantages and challenges faced by EVs to penetrate the market, and to outline state-of-the-art research and technologies that are driving the creation of newer and better EVs for adoption in the smart cities of tomorrow.
