TL;DR: In this article, the relationship between ambient air quality and city size and how it might differ between urban areas of developed and developing countries is investigated. But the relationship is not inevitable and tends to diminish with economic growth and the capacity for undertaking pollution abatement measures.
Abstract: This study presents a quantitative assessment of the environmental consequences of urbanization in general and city bigness in particular in the context of the process of economic development. We focus attention on the relationship between ambient air quality and city size, and how it might differ between urban areas of developed and developing countries. First, the air pollution-city size relationship is characterized theoretically and explored empirically using ambient air quality data for various urban zones across an international sample of cities. While we find statistically significant relationships between pollution and city size, interesting developed-developing country differences emerge. Next, the relationship is re-estimated using contextual development covariates. Results show that the positive association between poor air quality and city size is not inevitable and tends to diminish with economic growth and the capacity for undertaking pollution abatement measures. It follows that restricting...

TL;DR: The IPCC assessment of climate change is full of assumptions unfair to the developing countries as discussed by the authors, and it is essential that revisions take these problems into account if effective strategies are to ensue.

TL;DR: Aerosol samples were collected in an industrialized region of Bombay and analyzed for twenty seven chemical species using inductively coupled plasma emission spectroscopy, energy dispersive x-ray fluorescence spectroscope and UV/VIS spectrophotometry as mentioned in this paper.
Abstract: Aerosol samples were collected in an industrialized region of Bombay. These were analyzed for twenty seven chemical species using inductively coupled plasma emission spectroscopy, energy dispersive x‐ray fluorescence spectroscopy and UV/VIS spectrophotometry. Factor analysis applied on nineteen marker elements extracted seven factors indicating seven major source types contributing to aerosol mass at the sampling sites. Multiple regression taking absolute factor scores as predictors was employed for source apportionment. Finally, source profiles were calculated as percentage of the aerosol mass and compared with the values reported in the literature.

TL;DR: The authors developed a simple multiplier-accelerator model of a market economy, where the strength of the accelerator relationship between current investment and past output depends on the state of the economy.
Abstract: The paper develops a simple multiplier-accelerator model of a market economy, where the strength of the accelerator relationship between current investment and past output depends on the state of the economy. It is found that the greater the values of the multiplier and the accelerator, the more persistent and aperiodic («chaotic») would be the cyclical behaviour of the economy.
