“…Ambient air concentrations at the point of stack deposition did not exceed the USEPA (2011), WHO (1998), PAK EPA (2012), and WB (2012) ambient air quality standards. (Goyal et al, 1996). The sampling point in nearby field was the same at 100% coal use and at the maximum level of substitution i.e.…”

Tyre derived fuel (TDF) has a potential advantage for its use as a co-fuel with coal in rotary kilns of cement plants. In this study we analyzed the emissions of selected criteria pollutants; CO 2 , CO, NO x , SO x and PM to suggest suitable proportion of TDF to replace coal when different proportions of TDF and coal were used as cement kiln feed. Emissions of CO 2 , CO, NO, NO 2 , SO 2 and total PM from stack and concentrations of CO, NO x , SO x and PM 10 in ambient air were assessed using USEPA recommended methods. Substitution such as 85% coal and 15% TDF, 80% coal and 20% TDF, 75% coal and 25% TDF and 70% coal and 30% TDF were applied in this study. Results of the current study revealed a rise in CO and TPM stack emissions with an increase in proportions of TDF and crossed standards at 80% coal and 20% TDF. Decline in NO x emissions up-till 15% proportion of TDF was observed and remained lower than the emission of NO x at 100% coal use in spite of an increase in its concentration at each increased proportion of TDF above 15% TDF use. No significant difference (p > 0.05) in ambient air pollutant concentration with and without TDF use was observed. The study suggested 15% TDF substitution as a preferable proportion for the selected cement plant.

Article Highlights• A study of the impact of nuclear reactor RA in Vinca on its environment using Gaussian model • The total dose was modeled using dose factors • Meteorological data for the six-year period were used • Nuclear reactor RA could not affect the environment above the prescribed limit Abstract Research activities of Vinca Institite have been based on two heavy water research reactors: a 10 MW one, RA, and zero power, RB. Reactor RA was operational from 1962 to 1982. In 2010, spent fuel has been sent to the country of origin, and the reactor now is in decommissioning. During the operational phase of the reactor there were no recorded accidental releases into the environment, only operational ones. Results of the environmental impact assessment of the assumed emission of radionuclides from the ventilation of nuclear reactor "RA" in Vinca to the atmospheric boundary layer are presented in this paper. Evaluation was done by using the Gaussian straight-line diffusion model and taking into account characteristics of the reactor ventilation system, the assumed emission release of radioactivity (from the literature), site-specific meteorological data for six-year period and local topography around nuclear reactor, and corresponding dose factors for inventory of radionuclides. Based on the described approach, and assuming that the range of appropriate meteorological data for six year period for the application of described mathematical model is enough for this kind of analysis, it can be concluded that the nuclear reactor RA, in the course of its work from 1962 to 1982, had no influence on the surrounding environment through the air above regulatory limits.

“…Smaller particles less than 2.5 microns in diameter generally come from combustion of fossil fuels. The emissions from lime kilns consisted of gaseous and particulate matter as a result of combustion of coal and limestone (Goyal et al, 1996). SO 2 is emitted largely from burning coal, high-sulphur oil, and diesel fuel.…”

In present study, an extensive health survey of 573 lime kiln workers of Maihar and Jhukehi region of Madhya Pradesh was done for impact assessment of occupational and environmental health hazards' exposure on their health behavior. Various physical and physiological disorders of workers were screened with the cooperation of physicians and consultants. Among the observed health anomalies, eye disorders with 39.08% were ranked the highest, followed by respiratory disorders (20.06%), cardiovascular disorders (17.44%), skin disorders (15.70%), and gastrointestinal disorders (7.64%). Health illness was observed to increase with aging and length of hazard exposure.
