“…Certain characteristics of FAs are fairly uniform. Fly ash consists of much minute glass like particles of 0.01 to 100 mm size (Davison et al 1974;Bhanarkar et al 2008) having specific gravities 2.1 to 2.6 g m -3 (Bern 1976). Some spheres of FA are hollow (cenospheres), while others (plerospheres) are filled with small amorphous particles (Hodgson and Holliday 1966).…”

Over the past few decades there has been avid interest in developing the strategies for the utilization of Fly ash (FA). Major foci have been on its agricultural application. It is often economical to use FA as a soil amendment. The potential of FA as a resource material in agriculture is due to its specific physical properties like's texture, water holding capacity, bulk density, pH etc., and contains almost all the essential plant nutrients. It can be used as in soil that cannot substitute the chemical fertilizers or organic manure it can be used in combination with these to get additional benefits in terms of improvement in soil physical characteristics, increased yields etc. The amount and method of FA application in soil would vary with the type of soil, the crop, grown, the prevailing agro climatic condition and also with the FA characteristics. Although, as an input material FA has many benefits for agriculture applications like, improvement of nutrient deficiency, effectively control various pests infesting etc., in contrast FA also contains number of toxic heavy metals and also have natural radioactivity materials in it. Therefore, proper attention should be given on some important areas related to FA utilization such as long term studies of impact of FA on soil health, heavy metal uptake, plant physiology and growth, crop quality, and continuous monitoring on the soil characteristics. While using FA in agriculture problem of heavy metal toxicity and leaching due to excess dose should also be kept in mind.

“…It was observed that the particles and associated metals, particularly with fine dust, remain suspended in air longer under certain meteorological conditions. Road dust, an important environmental indicator of metal contamination from atmospheric deposition, receives varying inputs of anthropogenic metals from various stationary and mobile sources such as vehicular traffic, industrial activities, power plants, residential fossil fuel burning, waste incineration, construction and demolition activities, and resuspension of contaminated soil (Bilos et al, 2001;Charlesworth et al, 2003;Bhanarkar et al, 2005Bhanarkar et al, , 2008Gupta et al, 2012). Road dust, therefore, is a significant contributor of pollution in the urban environment.…”

RESUMENLa contaminación del aire es considerada como uno de los mayores desafíos ambientales debido a sus efectos sobre los ecosistemas y la salud humana. En este estudio se investigan los niveles de concentración y las fuentes de la contaminación por metales pesados en muestras de polvo de caminos recolectadas en varios sitios que incluyen áreas con cuatro actividades diferentes en Delhi, India: industriales, carreteras, residenciales y de uso mixto. El contenido de metales en polvo de caminos se analizó mediante espectroscopia de emisión atómica por plasma de acoplamiento inductivo. Los resultados muestran altos niveles de concentración de Ni, Cr y Pb en áreas industriales. Los coeficientes de correlación de Pearson acoplados con análisis de componentes principales revelaron que el CD, el Cr, el Ni y el Pb están vinculados con fuentes industriales en tanto que el Zn y el Cu proceden principalmente del tráfico vehicular. La contaminación en polvo de caminos se valoró a través de varios métodos: grado de contaminación, índice ecológico e índice de contaminación. El análisis de los factores de contaminación reveló que las muestras de polvo de caminos estaban contaminadas de manera considerable con Zn y Pb. Los índices de potencial ecológico indicaron la presencia de contaminación significativa por Cd y moderada por Pb en el polvo de camino, en tanto que la contaminación por Cr, Cu, Ni y Zn fue baja. El índice de contaminación de la mayoría de los metales fue mayor a 1, lo cual revela un deterioro en la calidad del polvo de caminos en Delhi a causa de las emisiones antrópicas. El grado de contaminación, el índice de potencia ecológico y el índice integrado de contaminación indican que el polvo de caminos en áreas industriales, de carreteras y de uso mixto exhiben alta contaminación por metales pesados. El polvo del camino también está contaminado de manera significativa. Evaluaciones realizadas por diversos métodos indicaron que todas las técnicas son importantes para valorar la calidad ambiental. ABSTRACTAir pollution has been considered one of the major environmental challenges because of its effect on ecosystems and human health. The concentration levels and sources of heavy metals contamination were studied in road dust samples collected from various locations including four different activity areas: industrial, highways, residential and mixed use in Delhi, India. Metal content in road dust was analyzed by inductively coupled plasma atomic emission spectroscopy. The results showed high concentration levels of Ni, Cr and Pb in industrial areas. Pearson's correlations coupled with principal component analysis revealed that Cd, Cr, Ni and Pb are associated with industrial sources whereas Zn and Cu are mainly contributed by vehicular traffic. Road dust contamination was assessed by various methods: degree of contamination, potential ecological index and pollution index. Contamination factor analysis showed that road dust samples are significantly contaminated by Zn and Pb. The potential ecological indices indicate...

“…Emissions of PM, SO 2 , and NO x from industrial sources vis-à-vis steel industry have been reported earlier (USEPA 1987;Bhanarkar et al 2003Bhanarkar et al , 2005aBhanarkar et al , 2008Wang et al 2003;Taib 1995). Prediction of impacts of emissions on the receiving environment is important as ambient air quality is critical for public health.…”

Integrated pipe manufacturing industry is operation intensive and has significant air pollution potential especially when it is equipped with a captive power production facility. Emissions of SO(2), NO(x), and particulate matter (PM) were estimated from the stationary sources in a state-of-the-art pipe manufacturing plant in India. Major air polluting units like blast furnace, ductile iron spun pipe facility, and captive power production facility were selected for stack gas monitoring. Subsequently, ambient air quality modeling was undertaken to predict ground-level concentrations of the selected air pollutants using Industrial Source Complex (ISC 3) model. Emissions of SO(2), NO(x), and particulate matter from the stationary sources in selected facilities ranged from 0.02 to 16.5, 0.03 to 93.3, and 0.09 to 48.3 kg h(-1), respectively. Concentration of SO(2) and NO(x) in stack gas of 1,180-kVA (1 KW = 1.25 kVA) diesel generator exceeded the upper safe limits prescribed by the State Pollution Control Board, while concentrations of the same from all other units were within the prescribed limits. Particulate emission was highest from the barrel grinding operation, where grinding of the manufactured pipes is undertaken for giving the final shape. Particulate emission was also high from dedusting operation where coal dust is handled. Air quality modeling indicated that maximum possible ground-level concentration of PM, SO(2), and NO(x) were to the tune of 13, 3, and 18 microg/m(3), respectively, which are within the prescribed limits for ambient air given by the Central Pollution Control Board.
