In this study, the emission characteristics of PCDDs/DFs and gaseous matter from waste wood incinerators with capacity of 0.06~0.18ton/hr was evaluated based on the type and general features of waste wood; industrial pallet (material lumber), waste furnitures (medium density fiberboard, MDF), mixture of pallet and waste furniture, dismantling wood from construction work (material lumber) and waste vessels. The emission concentrations of PCDDs/DFs were 0.137, 1.835, 9.665, 6.585 and 128.316 ng-iTEQ/Sm3 for pallet+MDF, pallet, MDF, dismantling wood from construction work and waste vessels, respectively. The concentrations of PCDDs/DFs from the first four incinerators were lower than the allowable exhaust standard of 10 ng-iTEQ/ Sm3, but that from the last incinerator was almost 13 times higher than standard. In the distribution ratio of PCDFs and PCDDs, the former was more higher than the latter in all incinerators. CO concentrations of three incinerators were under the allowable exhaust standards, 200 ppm, and it could mean that the incineration of waste wood was operated with good combustion conditions. The emission concentration of sulfur oxides were not detected or very low compared with the allowable exhaust standards, 100 ppm. In all incinerators, the emission of nitrogen oxides was under the allowable exhaust standards, 150 ppm.

Dioxins(PCDDs; Polychlorinated dibenzo-p-dioxins, PCDFs; Polychlorinated dibenzofurans) are accumulated in the body through the food as a representative environmental pollutants. Dioxins are flowed into the environment through the incineration of chemical products and electrical products containing PCBs. Dioxins generated from incinerators can pollute the atmosphere and soil, and it were accumulated in the body through food. Therefore, the dioxins monitoring of agricultural products produced near incinerators are required to ensure the safety of agricultural products. In this study, the analysis of dioxins was carried out on the basis of the law of the U.S Environment Protection Agency (EPA) Method 1613 and Korean Food Standards Codex Method SOP. The fifty agricultural products were collected in the field around the incinerators. As a result, the concentration range of detected dioxins was (0.0507~0.5824) pg/g. In the range of concentrations that reflect the toxic equivalent factor is (0.00002~0.01631) TEQ pg/g. The contribution of agricultural products to the dioxins intake is not equally distributed: tomato (74%), Corn (15%), Cabbage (9%), Green pepper (2%), red pepper (0.04%), Blueberries (0.0006%). The estimated daily intake of Korean Population through agricultural products was 0.00430 pg TEQ/kg body weight/day, and it was estimated at about 0.11% of tolerable daily intake(TDI) of Korea. Consequently, Dioxins exposure levels of agricultural products produced near incinerators has been found to be very safe.

PCDD/Fs monitoring was carried out to estimate the contamination level in soil samples taken in the vicinity of the various incinerators throughout South Korea from July 2003 to December 2004. The levels ranged from N.D. to 130.39 pg I-TEQ/g (d.w.) with an average concentration of 11.38 pg I-TEQ/g (d.w.). The level of PCDD/Fs in this study is similar to that of other countries. Overall, the highest mean concentration in the soil was found at 250 m from the stack. In addition, the flue gases were analyzed in order to obtain the congener profiles of the PCDD/Fs emitted from the incinerators. The concentration of I-TEQ in the flue gas ranged from 0.33 to 21.5 ng TEQ/Sm3. These levels were much lower than the concentration stipulated in the Korean emission criterion (40 ng TEQ/Sm3 until 2005). The comparison of the congener patterns using cluster analysis showed that the incinerators and PCP are sources of PCDD/Fs in the soil samples according to the sampling point, but the possibility of unidentified combustion sources and vehicles exists in the case of complex industrial regions.

This study attempted to find an optimum operation codition for co-incineration of food waste and industrial wastes,focusing on injection position and rate. As the result of analysis, during injection of food waste incineration facilities,atmospheric pollutant standard satisfied all requirement. However when injected into the primary combustion chamber,the dioxin exceeded emission standard. This result has been determined that contaminants generated as processing themore amount (150 ton/day) than the designed capacity (72 ton/day) emitted and exceeded not completely removed fromthe control facilities.

The emission characteristics of mercury in waste incinerators were investigated to get basic data for the policy development on the emission reduction of mercury (Hg). For the study several important factors were analysed from 4 incinerators such as mercury concentration, emission factors and removal rate for control devices. The results are listed below. Mercury concentrations in the flue gas were 0.39∼5.96㎍/S㎥ in MWI and 2.5∼8.8㎍/S㎥ in IWI. The distributions of gaseous and particulate mercury in flue gas were above 99% and below 1%, respectively. Therefore, in order to remove mercury effectively, it is important to control the gaseous mercury. Mercury concentrations in fly ash collected from control device were found as 16.2∼35.6 mg/kg-ash in FF of MWI. Also mercury concentrations at the front and hack point of control device of MWI were 33.45∼62.65 ∼g/S㎥ and 0.88∼3.49㎍/S㎥, respectively. Emission factors were estimated as 3.67∼11.67mg/ton in FF, 2.6∼24.5 mg/ton in MWI with SNCR, SDR and FF, 54.9∼192.7mg/ton in IWI with Cyclone and FF. Emissions from Municipal Waste Incinerator were found both in minimum and maximum ranges. Annual mercury emissions emitted from MWI was estimated as 20.0kg (6.0∼33.9 kg).

환경위험의 다면성과 일반인들의 주관적 위험인지:쓰레기 소각시설로부터의 건강위험을 사례로

Individual and societal perceptions of environmental risks are multidimensional and complex. Previous research in the western countries found that personal, psychological, political and socio-economic factors interact with technological factors, and affect subjective perceptions in complex ways. This study empirically investigates determinants of risk perceptions concerning health risks from dioxin, using a survey sample of 594 homeowners living near waste incinerators in the Kyoungi province and Seoul area. There is great variability in subjective beliefs about dioxin risks with a bimodal distribution of responses, which suggests a potential disparity in risk judgement between experts and lay people. Nonetheless, those variations in perceptions are not random, but are systematically related to individuals' personal attitudes and demographic variables such as age, income, and distance. 정책적 시사점

Domestic industrial waste small-scale industrial incinerators produce less than 200 kg/hr; this study chose 13 of the 249 potential facilities. The target average emissions for air pollutants resulting from the facilities were SOx 13.56 ppm, NOx 82.74 ppm, NH3 19.95 ppm, HCl 54.33 ppm, HF 0.84 ppm, Hg N.D, As 0.1 ppm, H2S N.D. Dust and heavy metal analysis results for the facilities revealed Dust 32.51 mg/Sm3, Cd 0.04 mg/Sm3, Pb 0.20 mg/Sm3, Cr 0.08 mg/Sm3, and Cu 0.03 mg/Sm3. Combustion indicators were O2 11.58% and CO 271.20 ppm. Average PCDDs/DFs were 17.87 ng ITEQ/ ton. The target facilities were equipped with anti-pollution facilities. However, some items were found to exceed the emission standards. These results are even equipped with control facilities due to manual limitation actions of the management personnel. Therefore, it is determined that the emission control of contaminants is difficult.

For 8 years before and after COVID19 in H-gun, a small and medium-sized rural city, a quarterly survey and analysis was conducted on changes in physical and chemical characteristics of domestic waste brought into the domestic waste incinerator input. Apparent density, three-component, and elemental analysis were performed, and based on this, the calorific value of waste to be recycled was calculated. Through this, the following results were obtained about the characteristics of household waste generation in rural small and medium-sized cities before and after the COVID19 pandemic. First, since the COVID19 pandemic in the fourth quarter of 2019, the content of plastics and fibers has increased relatively, and this reason is judged to be the result of the increase in the use of plastic packaging materials and masks. Second, in the case of moisture content and combustible content before and after COVID19, a decrease in moisture content and an increase in combustible content were evident overall, except for the quarter of a specific year. Third, comparing the low calorific value before and after COVID19, it was higher than about 3,000 kcal/kg from the fourth quarter of 2019, except for 2016, after the COVID19 pandemic.
