Air Quality Mapping using GIS and Economic Evaluation of Health Impact for Mumbai City, India (Journal of the Air & Waste Management Association) (Awkash Kumar, Jorgen Brandt, Anil Kumar Dikshit and Rashmi S Patil,66,5,470-481, Year: 2016)
Mumbai, a highly populated city in India, has been selected for air quality mapping and assessment of health impact using monitored air quality data. Air quality monitoring networks in Mumbai are operated by National Environment Engineering Research Institute (NEERI), Maharashtra Pollution Control Board (MPCB), and Brihanmumbai Municipal Corporation (BMC). A monitoring station represents air quality at a particular location, while we need spatial variation for air quality management. Here, air quality monitored data of NEERI and BMC were spatially interpolated using various inbuilt interpolation techniques of ArcGIS. Inverse distance weighting (IDW), Kriging (spherical and Gaussian), and spline techniques have been applied for spatial interpolation for this study. The interpolated results of air pollutants sulfur dioxide (SO2), nitrogen dioxide (NO2) and suspended particulate matter (SPM) were compared with air quality data of MPCB in the same region. Comparison of results showed good agreement for predicted values using IDW and Kriging with observed data. Subsequently, health impact assessment of a ward was carried out based on total population of the ward and air quality monitored data within the ward. Finally, health cost within a ward was estimated on the basis of exposed population. This study helps to estimate the valuation of health damage due to air pollution.
Arsenic removal from drinking water by electrocoagulation using iron electrodes-an understanding of the process parameters (Journal of Environmental Chemical Engineering ) (Banerji, Tuhin,4,4,3990-4000, Year: 2016)
Various methods exist for arsenic removal from water, but most are not viable as they require addition of oxidants and use adsorbents which have limited adsorption capacities. Electrocoagulation using iron electrodes (ECFe) is a promising technology for arsenic removal. Efficiency of arsenic removal by ECFe may be affected by parameters such as pH, current intensity, initial arsenic concentration and co-occurring ions like phosphate, silicate, natural organic matter (NOM), bicarbonate, sulphate, nitrate and chloride but the causal action is not well understood. Thus experiments were designed and carried out to observe these effects and get a better understanding of ECFe. The results indicate that the oxidation of Fe(II) generated during ECFe is essential for high efficiency (with respect to iron dose) of arsenic removal. Lower current intensities and pH7 were found to be most efficient for arsenic removal per unit weight of iron dissolved. Observations indicate that arsenic reacts with ferric (hydr)oxides and phosphate complexes with Fe(II). With time these complexes and precipitates are reordered to give a much higher affinity of iron (hydr)oxides for phosphate. Silicate, upto 20 mg/L, had negligible effect but at 30 mg/L was seen to reduce arsenic removal by ECFe. Increasing NOM concentrations also reduced arsenic removal but bicarbonate, sulphate, nitrate and chloride had no effect on arsenic removal by ECFe. Presence of old ferric (hydr)oxides in the reactor led to lesser requirement of Fe(II) to achieve less than 10 ppb concentration as it promoted interfacial reactions. Formation of FeAsO4 was observed by FTIR analysis of the precipitates.
