The main objective of this study was to establish optimal incineration conditions through the analysis of pollutant formation mechanisms involved in the combustion process of a retort incinerator. Calorific values of several types of municipal solid wastes were determined and related to specific incinerability indexes. The incinerability testing concerning this study was conducted on residues with an incinerability index （II） of 123. The samples were tested under different conditions： with and without chamber preheating, varying the percentage of inlet air （25, 50 and 75% of the system capacity）, measuring the temperatures of the primary and secondary chambers, and gauging the CO and NO stack emissions with an electrochemical cell. With comparative purposes in mind, samples with indexes ofI = 112, I = 123, I = 130 and I = 132 were also tested to assess the influence of the II on pollutant emissions.

Individual exposures to particulate matter and endotoxin in dairies have increased as operations have transitioned to larger herd sizes. A cross-sectional study at 13 California dairies and one non-dairy control facility was conducted to determine associations between endotoxin concentrations measured in fine particulate matter (PM2.5) and respiratory function in these workers. Previous research found that dairy work was associated with acute airway obstruction in comparison to controls. While endotoxin levels in PM2.5 have been previously reported, their effects on lung function have not been studied among California dairy workers. This paper also examined correlations with PM2.5 concentration, inhalable particulate matter (IPM), and endotoxin in IPM. Personal samples collected from a total of 185 dairy workers and 45 control workers were included in the analyses. Findings showed that dairy facilities had higher (p 2.5 when compared with the control facility (3.3 EU/m3, 0.6 EU/m3, respectively). Endotoxin in PM2.5 was weakly correlated with PM2.5 concentration (r2 = 0.16, p 2 = 0.35, p but not with IPM concentration. When controlling for age, ethnicity, smoking, height and personal protective equipment use, PM2.5 endotoxin exposure was associated with lower crossshift in forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) only among taller workers (p = 0.006). This is the first study to present personal occupational exposures to endotoxin in PM2.5 measured on Californian dairies. Despite lower levels than in other industries, such as poultry farms, this study suggests that some workers may be affected, and efforts should be aimed at mitigating pollutants in order to maintain endotoxin concentrations below recommended levels.
