There has been discrepancies between the daily air quality reports of the Beijing municipal government, observations recorded at the U.S. Embassy in Beijing, and Beijing residents' perceptions of air quality. This study estimates Beijing's daily area PM(2.5) mass concentration by means of a novel technique SPA (Single Point Areal Estimation) that uses data from the single PM(2.5) observation st...

Municipal solid waste (MSW) remains a major problem in modern societies, even though the significant efforts to prevent, reduce, reuse and recycle. At present, municipal solid waste incineration (MSWI) in waste-to-energy (WtE) plants is one of the main management options in most of the developed countries. The technology for recovering energy from MSW has evolved over the years and now sophisti...

Air pollution can influence women's reproductive health, specifically menstrual cycle characteristics, oocyte quality, and risk of miscarriage. The aim of the study was to assess whether air pollution can affect the length of the overall menstrual cycle and the length of its phases (follicular and luteal). Municipal ecological monitoring data was used to assess the air pollution exposure during...

The incineration of municipal waste has been the subject of controversy for many years and has been widely opposed because of concerns about the pollution of the air with toxic materials, particularly dioxins. Many incinerators have had to stop operation and many projects have been abandoned. At the same time, communities continue to be faced with the challenge of handling growing amounts of wa...

Pilot plant tests on a 220 ton-per-day continuous feed municipal incinerator demonstrates the technical feasibility of electrostatic precipitation for control of stack emission. Data on the nature of the furnace stack gases and the physical characteristics of the dust as well as performance of a pilot unit treating ap­ proximately 600 cfm are presented. Part I Trends in Refuse Disposal by Incin...

Air pollution had become a vital concern for the 2014 Youth Olympic Games in Nanjing. In order to control air pollutant emissions and ensure better air quality during the Games, the Nanjing municipal government took a series of aggressive control measures to reduce pollutant emissions in Nanjing and its surrounding cities during the Youth Olympic Games. The Air Quality Index (AQI) is an index o...

A description is given of settling chambers with sprays, cyclone types and electrostatic precipitators as used in municipal incinerators. Special emphasis is placed on selection and duct design especially to inlets of collectors which affects efficiency. Importance is stressed on preventing leaks and overfilling of hoppers and proper maintenance of equipment in order to obtain optimum efficienc...

The public health aspects of incinerator exhaust gases are discussed first in the light of the physio­ logical response induced by specific contaminants such as sulfur oxides, nitrogen oxides, and other inorganic gases and aldehydes, organic acids, esters, polynu� clear hydrocarbons' , and other organic compounds; second, with respect to their relation to illness caused by air pollution in gene...

The fust reactic n to a paper that reports the necessity for complete replacement of air pollution control and ash removal equipment is likely to be "What a disaster". But the matter must be put in proper perspective. By compari­ son with Nashville and other operating plants which have required replacement of major components early on, Gal­ latin doesn't look so bad. Consider fiascos such as th...
