“…The smaller the grain size is, the more hazardous it is. The PAHs causing cancer and mutation are mainly from particulate matter of soot by ingestion or skin contact (Zhang et al 2007). The PAHs in air of coal-mining districts mainly come from coal gangue spontaneous combustion and small coal particles in the air.…”

This paper addresses the distribution and occurrence of harmful organic substances in coal gangue dump from Jiulong Coal Mine and its influence on the environment. The samples were taken from the coal gangue dump and coal waste water stream and analyzed by organic geochemical methods. The results indicate that the coal gangues contain abundant harmful organic substances like polycyclic aromatic hydrocarbons. The TOC and sulfur contents of the samples are much higher than those of the background sample except Sample JL7. The contents of organic bulk parameters are relatively high. Ten carcinogenic PAHs were identified and these harmful organic substances have influenced the surrounding area. Along the waste water stream, organic substances pollute at least 1,800 m far from the coal gangue dump.

A preliminary Indoor Air Quality study was performed in 26 residential homes in 6 cities in different climate zones in China. In Chinese urban environments, coal gas and natural gas are used as the main fuels for cooking. Analysis of the results employed the ratio of living room to kitchen (L/K) pollutant concentrations and the correlation of their levels to assess the transport of pollutants indoors. Sources in the kitchen affect living room concentrations of SO 2 , NO, NO 2 , and CO, less so that of CO 2 levels and weakly of PM 10 . Among all the pollutants, SO 2 has the minimum 0.88 L/K ratio value, and maximum correlation value, R 2 ¼ 0.89; on the other hand, PM 10 has the maximum L/K ratio value, 1.20 and minimum R 2 -value, 0.55, which means that PM 10 is mostly influenced by activities and other factors that do not take place in the kitchen. Concentrations of SO 2 differed significantly depending on the fuel type used for cooking with coal gas producing 87.6% higher SO 2 concentrations than natural gas. Concentrations of CO 2 and PM 10 were the same regardless of gas type. The type of ventilation was found to influence pollutant concentrations with a mechanical exhaust system showing higher efficiency than a natural ventilation system in exhausting pollutants. The period and style of cooking also affected concentrations of pollutants in the kitchen.

“…The combustion product toxic gases are also produced with pool fire that severely affects the workers working on offshore platform. The average height for a person to inhale air is 1.5 m , so concentration of CO is measured at this specific level on cellar deck [30]. Fig.…”

The processing area of offshore platform has high probability of leakage of hydrocarbons. Liquefied Natural Gas (LNG) is one of the most common hydrocarbon produced in offshore platforms. Leakage of LNG can cause pool fire, jet fire, flash fire or fire ball. Thermal radiations due to fire is the major source of damage to workers on board. But due to fire, various combustion product toxic gases are also produced that have both acute and chronic health effects. These toxic gases can cause incapacitation, increased heart rate, vomiting and even death. Predicting the human injury due to thermal radiations and concentration of toxic gases are the key issues. A risk based approach takes in to consideration the duration a worker spent on different location of offshore platform and also it has the additive ability to evaluate overall risk due to fire radiation and toxic gases. Grid based approach helps in better visualization of risk posed by fire radiation and combustion product toxic gases at different locations of platform. The current study proposed an integrated consequence modelling approach for fire and combustion product toxic gases using risk based and grid based approaches. The integrated accident is modelled using Computational Fluid Dynamics (CFD) code Fire Dynamics Simulator (FDS). The results showed that risk posed by thermal radiation is confined on sub cellar deck (lower deck) but estimated risk due to combustion product gas (carbon monoxide) on cellar deck (upper deck) has significant value that needs to be considered. The current approach would be useful for emergency preparedness plans and safety measures designs for offshore platforms.
