Recessive Mutations

It has been reported by the Ministry of Environment in Kosova that particle emissions from one of the units of the coal-fired power plants (Kosova A) in Kastriot/Obiliq were exceeding the European standard by some 74 times. Besides the particle emission, there is also release of sulphur dioxide, mono-nitrogen oxide (NOx), carbon monoxide, carbon dioxide, organic compounds and heavy metals. In addition, there is also release of heavy metals and organic compounds from a nearby solid waste dumpsite. Together, they are considered to be responsible for the increased health problems of the population living in the vicinity.To study the genetic effects of these emissions we focused on the genetic load, that is, recessive mutations that affect the fitness of their carriers, of exposed wild living Drosophila melanogaster. The effects of ash from the dumpsite on the other hand were investigated upon feeding the ash with the nutrient medium. Our results revealed that the D. melanogaster population from the Kastriot/Obiliq area carries a high genetic load of 54.7%. Drosophila fed with the nutrient medium containing ash in a concentration of 1% carried a genetic load of 37.1%, whilst increasing concentrations (2% and 3% of ash) led to higher genetic loads of 68.7% and 67.4%, respectively.

The heavy metals including Pb, Cd, Cr, As and Mn emission characteristics of coal-fired power plant boilers, industrial boilers, lead and zinc smelters, cement kilns, and steel industries were studied in this paper. The removing effects of heavy metals by pollution control technology were analyzed. ICP-AES method was used to measure the contents of heavy metals in solid samples. In addition, M-29, the U.S. EPA isokinetic sampling method was used to sample heavy metals in the flue gas, and the sampled heavy metals were tested by ICP-AES-hydride generator system. For coal-fired boilers, heavy metal contents in descending order were Mn, Pb and Cd in the tested coal. The heavy metals’ emission concentrations of coal-fired industrial boilers were much higher than the heavy metals’ emission concentrations of power plants. For the lead and zinc smelters, Pb and its compounds in flue gas after cleaning can meet the emission standards. The heavy metal contents in the cement raw materials in descending order were Pb, Cr and Cd. For the sintering mixture, the heavy metal contents in descending order were Pb, Cr and Cd as well. The removal effects of heavy metals by existing pollutant control technologies in the various typical industries were also tested and analyzed in the paper. The research did in the paper made a scientific basis for controlling heavy metal emissions from typical industries.

The size of combustion generated particles ranges from a few nanometers up to 1 micron, whereas the size of naturally occurring PM such as pollens, plant fragments, and sea salt is generally larger than 1 micron. Particles generated by photochemical processes in the atmosphere are generally smaller than 1 micron. Ultrafine particles (UFP), also called “nanoparticles”, are <0.1 micron and in recent yearshave attracted attention due to potential adverse health effects associated with them. The contribution of UFP to the total PM mass is very small. However, they dominate the total number of particles in urban aerosols. Their sources are both mobile and stationary combustion sources and also gas-to-particle conversions. In coal and waste combustion systems, UFP are hypothesized to be generated mainly by nucleation of metal vapors. Coal naturally contains a vast range of inorganic elements among which are heavy metals. Sources of heavy metals in MSW include batteries, electronic devices, light bulbs, house dust and paint chips, food containers, used motor oils, plastics, yard wastes and some papers. The input of these metals into WTE facilities can be controlled by better source-separation of metal-containing materials. In 2007 almost 50% of the approximately 4.16 billion MWh generated in the United States was produced by coal power plants whereas only 0.3% was generated by the WTE industry. A preliminary study has shown that in terms of contribution to UHF in the atmosphere, MSW combustion has a minor effect in comparison to coal-fired power plants in the U.S. This paper will report on the results of this investigation.

The growing demand for electricity resulted in the construction of many coal fired power plants. The increment of the consumption of coal by power plants lead up to production of coal ash. Coal ash contains a range of toxic elements that may have negative effects to human and environmental health. Fly ash (FA) and bottom ash (BA) are the solid residues and mostly arise from coal combustion that being disposed in large quantities every year. The focus of the study is to determine the leachability of Self-Compacting Concrete (SCC) incorporated with FA and BA by using Static Leachate Test (SLT) method. In this study, FA and BA were collected from Kapar Energy Ventures Coal Power Plant in Selangor. The characteristics of Ordinary Portland cement (OPC), FA and BA were determined by using X-Ray Fluorescent (XRF) technique. The different percentages of FA (replace cement) and BA (replace sand) which is 0%, 10%, 20% and 30% were incorporated respectively into SCC. Ten reactors were set up for the leachability test for each solid specimen by using SLT method. The concentrations of leachate samples were analyzed for selected heavy metals content by using Atomic Absorption Spectroscopy (AAS) method. After 40 days conducting the test, the concentrations of selected heavy metals (As, Mn, Cu, Cr, Zn, Ni, Fe and Pb) in the synthetic acid rain leachates from the SCC specimens were significantly lower than the limit specified by the USEPA and EPAV. Therefore, incorporating of FA and BA up to 30% into SCC is potentially feasible.
