Assessment of heavy metal content in suspended particulate matter of coastal industrial town, Mithapur, Gujarat, India
Heavy metal concentrations in suspended particulate matter (SPM) were investigated for their distribution and source in the atmosphere of coastal industrial town, Mithapur, Gujarat, India. SPM, at 10 locations covering three seasons, were trapped on glass fibre filters using high volume samplers and quantification of metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) was done using Atomic Absorption Spectrometry employing HNO3 based wet digestion. Results show relatively low concentrations of SPM (211.3 to 375.2 ?g/m3) compared to National Ambient Air Quality Standard (NAAQS), specified By Central Pollution Control Board (CPCB, India), however, they were 2–3 times higher as compared to reference site. Among the heavy metals Cr, Mn and Pb levels were low, while Ni and Cd found to be exceeding the USEPA standards. The metal levels were also compared with those reported for other rural, coastal, industrial and urban parts around the world. Enrichment Factor analysis indicated that Cd, Zn, Cu, Pb and Ni were highly enriched relative to their crustal ratios (to Fe) and correspond to substantial contribution of anthropogenic source of these metals. The source identification was carried out by principal component analysis by applying a Varimax Rotated Component Matrix. |

Occurrence and distribution of selected heavy metals and boron in ground water of Gulf of Khambhat region, Gujarat, India
The concentration of selected heavy metals, like As, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn as well as B, was measured by inductively coupled plasma-optical emission spectrometry (ICP-OES) in groundwater samples from various locations in the Gulf of Khambhat (GoK), an inlet of the Arabian Sea in the state of Gujarat, India, during post-monsoon, winter, and pre-monsoon seasons in a year. Most heavy elements are characterized by low mobility under slightly alkaline and reducing conditions; concentrations in confined aquifers are smaller than the maximum permissible values for drinking water. The temporal changes indicate that a majority of metals is entering the aquifer during monsoon. Principle component analysis of the heavy metal data suggests that Co, Cu, Cd, and Zn are interrelated with each other and derived significantly from anthropogenic route, while input of Pb and Cr may be due to atmospheric deposition in the study area. Both weathering of rocks and anthropogenic input were found to be main sources of elements in the groundwater. The heavy metal levels in groundwaters of the GoK region in comparison with some of the European and Asian sites were higher; however, these metal levels were found to be comparable with few urban sites in the world. |

Water pollution of Sabarmati River- A Harbinger to Potential Disaster
River Sabarmati is one of the biggest and major river of Gujarat that runs through two major cities of Gujarat, Gandhinagar and Ahmedabad and finally meets the Gulf of Khambhat (GoK) in the Arabian Sea. A study was conducted to evaluate the water quality of this river, as it could possibly be one of the major sources for filling up Kalpasar, the proposed man-made freshwater reservoir supposed to be the biggest one in the world. A total of nine sampling stations were established covering 163 km stretch of the river from upstream of Gandhinagar city to Vataman near Sabarmati estuary. Physicochemical (temprature, pH, salinity, chloride, total dissolved solids, turbidity, dissolved oxygen, biochemical oxygen demand, phenol, and petroleum hydrocarbons), biological (phytoplankton), and microbiological (total and selective bacterial count) analyses indicated that the river stretch from Ahmedabad-Vasana barriage to Vataman was highly polluted due to perennial waste discharges mainly from municipal drainage and industries. An implementation of sustainable management plan with proper treatment of both municipal and industrial effluents is essential to prevent further deterioration of the water quality of this river. |

Investigation of Particulate Matter Performances in relation to Chalk Selection in Classroom Environment
This study aims to understand dust generation in classroom indoor for different chalk varieties and their potential doses to receptors in correlation with their physicochemical properties. Two representative chalks of extruded calcium carbonate and moulded gypsum type (total four) were used for writing on ceramic and wooden boards. Chalks were characterized using analytical techniques. Investigation of Particulate Matter (PM): PM2.5, PM10 and Total Suspended Particulate (TSP) concentrations in classroom air generated during the writing and wiping with chalk and board system was done. Dust collected beneath the board was analyzed for particle size distribution. Calcium carbonate made dustless chalks generate less PM during writing and wiping. They are quick settling and non-interacting with receptors, and deliver better utilization of material as compared to gypsum chalks. Physicochemical properties of the chalk constituents were invoked to explain the dust generation and its impact on the user. Surprisingly, dustless chalk made from Gypsum cannot be called really as dustless because of more PM emissions. The age-specific average potential dose for both PM10 and PM2.5 is higher for gypsum chalk as compared to the calcium carbonate chalks. The highest dose was estimated for the children in the age group of 6–11 years |
