Intensification of agriculture has been proposed as one way of minimizing emissions per unit of product, apparently legitimizing the ongoing structural changes in agriculture. We have investigated the relationship between the farming intensity and the nitrogen (N) dissipation by calculating the overall N emission factor (E: total N surplus per unit of N in the produce) from several studies of d...
We estimate the impacts of energy-led growth, quality life, and institutional factors on carbon emission intensity. Utilizing a balanced panel 21 Asia-Pacific Economic Cooperation (APEC) economies, we show that growth contributes heavily toward emissions. also demonstrate improved transparency help decimate pollution significantly. However, find human development employment exert direct influen...
a four year long research programme divided into four phases has been designed for the first time to assess the combined noise-air quality and combined exposure to noise-air pollution at the curbside open-air microenvironment of kolkata city, india. the results and the findings of the different phases of study had already been published. the objective of the review work is to fuse the findings ...
فعالیتهای انسانی تجمع فلزات سنگین را در خاک افزایش خواهد داد. آلودگی خاک به طور قابل توجهی کیفیت محیط زیست را کاسته و بر سلامت انسان اثرگذار است. پژوهش حاضر با هدف تعیین غلظت برخی از فلزات سنگین (نیکل، سرب، آهن، روی، کروم، کادمیوم) و ارزیابی تأثیر فعالیت مجتمع فولاد کرمان بر غلظت فلزات سنگین خاک صورت گرفت. تعداد 60 نمونه ازخاک سطحی از عمق 15-0 سانتیمتری، در فواصل متفاوتی از مجتمع فولاد کرمان ...
Presence of toxic metals in agricultural soils can impose adverse health impact on consumers. The main purpose of this study was to determine spatial distribution of elements Fe, Sb, Mn in agriculture soils and crops of Hamedan Province in Iran. Soil samples (0-20 cm depth) were collected from an area of 2831 km2. Iron, Antimony and Manganese in samples of soil and agricultural crop...
Environmental policy affects the distribution of market shares if intermediate goods are differentiated in their pollution intensity. When innovations are environment-friendly, a tax on emissions skews demand towards new goods which are the most productive. In this case, the tax has to increase along a balanced growth path to keep the market shares of goods of different vintages constant. Compa...
Heavy industrialization has resulted in the contamination of soil by metals from anthropogenic sources in Anniston, Alabama. This situation calls for increased public awareness of the soil contamination issue and better knowledge of the main factors contributing to the potential sources contaminating residential soil. The purpose of this spatial epidemiology research is to describe the effects ...
Based on panel data of 28 manufacturing industries sectors in 2005–2015 years, this paper first estimated the level of 28 manufacturing industries sectors technological progress, and then, using panel threshold technology, calculated the impact of three environmental regulation change rates on technological progress change rate to analyze the relationship between environmental regulations and t...
This paper investigates the effects of congested freeway traffic conditions on motorists’ exposure to trafficrelated air pollution using real-world traffic data and a framework of established emissions and dispersion models. The intent is to isolate and compare the influences of congested traffic characteristics on exposure duration and exposure intensity. Mass inhalation of carbon monoxide (CO...
