This study was conducted to determine the etiology of diarrhoea in a hospital setting in Kolkata. Active surveillance was conducted for 2 years on two random days per week by enrolling every fifth diarrhoeal patient admitted to the Infectious Diseases and Beliaghata General Hospital in Kolkata.

This work presents an estimate of the air pollution from municipal solid waste transport haulage sector for the city of Kolkata. About 3000 MT/day of solid waste are generated in the city presuming generation rate of 450-500 gm/capita resident/day. On an average, 205 private carriers transport 60% of daily generated garbage (responsible for 44% of total air pollutants from municipal solid waste transport), while around 109 nos. of departmental vehicles transport the remaining 40% of waste (responsible for 56% of total pollution emission from waste transport).

Textile processing plants operating in and around Kolkata utilize a wide variety of dyes and other chemicals. Many of these chemicals are not retained in the final textile product but are discarded after they have served their purpose or are driven off into the atmosphere during heat treatment. The main aim of this study is to determine the quantity of material loss during the dying operation in a mechanized textile dyeing industry.

The present study attempts to find out the distribution of superficial fungal infection with respect to socio-economic and demographic variables among a symptomatic group (112 individuals) in West Bengal. Moreover, an attempt has also been made to find out the risk factors associated with the superficial fungal infection type. The results show that Tinea corporis is the most common infection type and the risk factors associated with this infection are age, occupational types, history of prior corporis infection and unexposed parts of the body.

Ambient air quality at five busy petrol pumps in Kolkata, India is monitored for mono-aromatic hydrocarbons and carbonyls. Among the measured volatile organic compounds, toluene and formaldehyde were the most abundant. Source apportionment using chemical mass balance identified exhaust from roadway and refueling as the major sources.

This paper provides a comparative overview of urban transport in the world’s two most populous countries: China and India. Cities in both countries are suffering from severe and worsening transport problems: air pollution, noise, traffic injuries and fatalities,
congestion, parking shortages, energy use, and a lack of mobility for the poor.

Commuters' exposure to volatile organic compounds (VOCs) especially BTEX travelling in passenger cars in Kolkata, India were quantified in Phase I (2001–2002) and Phase II (2003–2004). Monitoring was made inside and in the immediate outside of passenger cars fitted with and without catalytic converters using different types of fuels, along two congested urban routes.
