“…The lowest consumption is observed for the Peruvian Macchu Picchu Station due to its operation only in the austral summer (COMNAP, 2008). Therefore, the current consumption of fossil fuel by the research stations poses a potential risk of direct release of organic compounds and trace elements into the environment (Fishbein, 1981;Vouk and Piver, 1983;Bícego et al, 2009;Taniguchi et al, 2009).…”

“…Furthermore, zinc is an important component of brass, bronze, die casting metal, other alloys, rubber, and paints. The environmental releases of zinc from sources of human origin far exceed the releases from natural sources [ 18 ] . The permissible concentrations of Zn in water and sediment/soil as per international standards are 5.0 mg/L and 300-600 mg/kg, respectively.…”

The production of heavy metals has increased quickly since the industrial revolution. Heavy metals frequently form compounds that can be toxic, carcinogenic, or mutagenic, even in very small concentrations. The usual techniques of removing metals from wastewaters are in general expensive and have many restrictions. Alternative methods of metal removal and recovery based on biological materials have been measured. Among various agents, the use of microbes for the removal of metals from industrial and municipal wastewater has been proposed as a promising alternative to conventional heavy metal management strategies in past decades. Thus, the present study aims to isolate and characterize bacteria from soil, sediment, and waters of metal-contaminated industrial area to study the zinc resistance patterns and the zinc bioaccumulation potential of the selected microorganism. Zinc analysis of the samples revealed that concentrations varying from 39.832 m g/L to 310.24 m g/L in water, 12.81 m g/g to 407.53 m g/g in soil, and 81.06 m g/g to 829.54 m g/g in sediment are present. Bacterial zinc resistance study showed that tolerance to Zn was relatively low (<500 m g/ml). Ten bacterial genera were represented in soil and 11 from water, while only 5 bacterial genera were recorded from sediment samples. Bacillus, Pseudomonas , and Enterobacter were found in soil, sediment, and water samples. Highly zincresistant Bacillus sp. was selected for zinc removal experiment. Zinc removal studies revealed that at pH 5 about 40% reduction occurs; at pH 7, 25% occurs; and at pH 9, 50% occurs. Relatively an increased removal of Zinc was observed in the fi rst day of the experiment by Bacillus sp. The metal bioaccumulative potential of the selected isolates may have possible applications in the removal and recovery of zinc from industrial ef fl uents.

“…It is generally considered that Be is organically associated in most coals; however, Be may appear in quartz and clay minerals associated with coal (Swaine 1990). According to Fishbein (1981), "Be in the environment chiefly arises from coal combustion." Despite this finding, a careful study by Gladney and Owens (1976) showed that "less than 4% of the Be in the coal burned is being emitted to the atmosphere.…”

Thisreport addresses thekey airtoxic emissions likely toemanatefrom continued and expandeduse ofdomestic coal.Itidentifies and quantifies thosetrace elements specified intheU.S.1990CleanAirAct Amendments, by tabulating selected characterization data on varioussourcecoalsby region,state, and rank. On the basisof measurements by various researchers, this report also identifies thoseorganic compoundslikely tobe derived fromthecoal combustion process (although their formation ishighly dependenton specific boiler confip ._-z:si_ns and operating condition.s). 1 INTRODUCTION 1.1 STUDY RATIONALE Significant changes are expected in the regulation of hazardous air pollutants (HAPs), changes caused primarily by Title III of the 1990 Clean Air Act Amendments (CAAA) and secondarily by Section l12(b) of the Clean Air Act (CAA), as amended in 1990 (U.S. Congress 1990). The CAA requires the regulation of 189 HAPs (later changed to 188 with the exclusion of hydrogen sulfide, H2S), although not all are considered significant for the generation of electricity. The U.S. Environmental Protection Agency (EPA) is required by the 1990 CAAA to promulgate rules for all "major" sources of any of these HAPs. According tu the Hazardous Air Pollutants section of the new Title III, any stationary source emitting 10 tons* per year (TPY) of one HAP or 25 TPY of a combination of HAPs will be considered and designated a major source. In contrast to the original National Emission Standards for Hazardous Air Pollutants (NESHAP), which were designed to protect public health to "an ample margin of safety," the new Title III, in its first phase, will regulate by industrial category those sources emitting HAPs in excess of the 10/25-TPY threshold levels, regardless of health risks. *The word "ton," abbreviated "T," means a short ton or 2,000 lb. The short ton is used as the unit of measure (rather than the metric ton = 103 kg) unless otherwise noted.
