We applied cluster analysis and principal component analysis (PCA) with multivariate linear regression (MLR) to apportion sources of polycyclic aromatic hydrocarbons (PAHs) in surface sediments of the Huangpu River in Shanghai, China, based on the measured PAH concentrations of 32 samples collected at eight sites in four seasons in 2006. The results indicate that petrogenic and pyrogenic source...

A survey of the River Kali in western Uttar Pradesh (India) has been carried out to assess the contribution of point and non-point sources of pollution to the river. The river shows strong seasonal dependence for various constituents and the water quality deteriorates sharply as it flows through Muzaffarnagar city. The important characteristic associated with the pollution of the river is the d...

Cameron Highlands is a mountainous area subjected to torrential tropical showers. It extracts 5.8 million liters of water per day for drinking supply from its rivers at several intake points. The water quality of rivers in Cameron Highlands, however, has deteriorated significantly due to land clearing for agriculture, excessive usage of pesticides and fertilizers as well as construction activit...

Mercury pollution is a persistent and increasing problem in the environment. Along with some natural sources of the metal, major man-made sources of mercury pollution include incinerators, fossil fuel plants, and municipal sewage systems. The EPA estimated that in 1989, approximately 643,000 kg of mercury was discarded as municipal solid waste, with 84% of it landfilled.

In the last 10 yr, Beijing has made a great effort to improve its air quality. However, it is still suffering from regional coarse particulate matter (PM10) pollution that could be a challenge to the promise of clean air during the 2008 Olympics. To provide scientific guidance on regional air pollution control, the Mesoscale Modeling System Generation 5 (MM5) and the Models-3/Community Multisca...

The key benefit of economic (or fiscal) instruments is that they would allow a given pollution target to be met for lower overall cost than traditional regulations a considerable advantage given the perceived high financial burden of regulatory compliance. There are other benefits too. Economic instruments grant firms and individuals greater autonomy in deciding how to meet targets; they create...

Since the early 1970s, environmental agencies have focussed most of their attention on large point sources and transport sources of air pollutants. The myriad of small sources scattered throughout suburban Australia, such as people’s heating appliances, lawnmowers and suburban restaurants, have received little attention. Perhaps this is simply because they are so dispersed or they may have been...

The study examines the problem of noise pollution in the wake of its ill effect on the life of the people. A crosssection survey of the population in Delhi State points out that main sources of noise pollution are loudspeakers and automobiles. However, female population is affected by religious noise a little more than male population. Major effects of noise pollution include interference with ...

Waterborne pathogens from faecal pollution continue to be major contributors to outbreaks of infectious disease in many areas around the world. While developed countries have made much progress in municipal wastewater treatment and management of agricultural wastes, faecal contamination of source waters for drinking, recreation and rearing of shellfish still contributes to outbreaks of infectio...
