Industry,incidents and casualties in South West England: what is their relationship and are there social inequalities in their distribution?

This ecological study aimed, through the analysis of 1,146 wards in the South West of England (1998–2002), firstly, to examine whether chemical incidents and public casualties are more likely near complex industry (emissions to land, air or water: Integrated Pollution Control industry, IPC) or industry with emissions to air only (Local Air Pollution Control industry, LAPC). Secondly, the study examined whether industry, incidents and casualties are found close to deprivation. Social inequalities were examined across quintiles of wards. Fifty-two wards (4.5%) contained an IPC industry and 712 (62.1%) an LAPC. Incidents occurred in 132 wards (11.5%), with casualties in 59 (5.1%). Chemical incidents occurred more frequently in wards with LAPC (152, IPC 20); the same was true of casualties (211, 12). With each additional LAPC site in a ward, the risk of an incident rose by 22% (95% confidence interval [CI] 8–38%), suggesting a dose–response relationship. No clear social inequalities were found. In the South West of England, the public are more likely to be affected by an incident occurring at a simple LAPC site rather than a complex IPC site. This has implications for emergency planning which, at present, focusses most attention on the larger, more complex IPC sites.     

Control of Environmental Noise

The article reviews the current state of knowledge of noise and how people respond to noise. Sources of community noise are discussed and existing federal legislation pertaining to noise is mentioned. Methods of reducing the noise impact on communities from aircraft, surface transportation, and industrial sites are presented. Interior noise in industry, OSHA noise standards and means of controlling the noise to minimize hearing impairment are emphasized.     

Factors Determining the Post-consumer Waste Recycling Burden

The environmental burden of collecting recoverables from households is generally omitted from life-cycle analyses comparing the environmental outcome of using secondary material from post-consumer waste (PCW) with virgin feedstock. However, this burden can be considerable, depending upon the characteristics of the collection methods employed. Given that the basic objective of recycling is to secure environmental benefits, it is vital that the burden of collection through both bring/dropoff and kerbside schemes is taken into account if a valid assessment of the environmental balance resulting from PCW recycling is to be made. This paper presents survey data comparing the burden of collection for different types of recycling provision. It describes the site and spatial characteristics determining the amount of transport dedicated to collection at bring/drop-off sites. Predictor variables are identified as measures of these characteristics, and the survey data compared with them. A regression model to assess energy use at bring/drop-off sites with varying characteristics is then developed. The potential uses of the techniques presented include the evaluation of the environmental burdens of recycling provision at the waste collection authority and regional level, allowing more informed choices to be made in the development of recycling provision from an environmental standpoint.
