“…In this way, we can effectively overcome the shortage of the evaluation method above. Many scholars have applied this method to environmental quality assessment in water [11,12] and atmospheric [13,14] aspects, but there are a few scholars applied it to the soil environmental quality evaluation [15,16]. In this paper, combining the situation of the heavy metal pollution of soil in Guixi, we applied pollution loss ratio method to soil environmental quality evaluation in district of sewage irrigated farmland, which is meaningful to the protection of ecological environment and the correct estimate of the economic losses caused by heavy metal pollution.…”

Taking paddy field sewage irrigated area in Guixi as an examples, pollution lost rate method was applied to pollution assessment of soil heavy metals. The results showed that the average single pollution lost rate of the soil heavy metals was in the order of Cu>Cd>Pb>Zn>As, and the average single pollution lost rates of Cu and Cd are higher than that of other metals, so the integrated pollution lost rate of the metals in any sample site is contributed by them. From the comprehensive pollution lost rate, most sample sites reached the intermediate level ( IV level) , and accounted for 76. 93% of the total sample sites. most of the samples are moderately polluted (IV level), accounting for 50% of the total number of sample sites, The sample sites of No5 and No6 are slightly polluted (III level), accounting for 33%, and only No1 are heavily polluted (Vlevel), accounting for 16.67% of the total sample sites. As a result, the pollution lost rate method manifested more resolving power in the serious pollution index of the soil.

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.
