Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. The key difference in pathways is that photobioreactors are less likely to be colonized by toxin-producing strains than open ponds (Table 5-11). Meikleham, T.J.S. The sustainability indicators for potential changes in local climate are trends in relative humidity and trends in temperature distribution statistics. Mata, T.M., A.A. Martins, and N.S. Advances in Meteorology 2010(Article ID 408696). answer choices. Growth and nutrient removal in free and immobilized green algae in batch and semi-continuous cultures treating real wastewater. Solid waste from algal biofuel manufacturing processes is most likely to be generated as sludge from an anaerobic digester from which the volatile organic acids have been converted to methane and CO2; the methane is useful as a fuel supplement for the process.

Fish yield is affected by phytoplankton1 biomass and by the nutrient ratios in the edibility of phytoplankton (Oglesby, 1977; Bachmann et al., 1996). Journal of Bacteriology 177(20):6021-6026. Weber, C.L., and H.S. Many cyanobacteria and eukaryotic microalgae are cosmopolitan in their spatial (biogeographical) distributions and therefore could not be invasive if released in regions included in their broad habitat range. Water is essential to all life on Earth and a shortage of this vital resource in the environment is bound to negatively affect all forms of life. Pp. 2010. Minnesota ethanol plants’ price is pollution. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. 1. 2007. The environment helps sustain the population growth of an orgamism. Secure and reliable energy supplies—Coal becomes a “future fuel.” Available online at http://www.netl.doe.gov/KeyIssues/future_fuel.html. 4.In what way does water help in the life cycle of organisms? Moreover, waters that are in motion can interfere with the surface tension required for mosquitoes’ respiratory siphons to function (Schober, 1966). Gonzalez, L.E., R.O. Rabalais, N.N., R.E.

Many sustainability indicators relevant to waste are described elsewhere, for example, quantifying recycling of nutrients and salinity of ground water. Arsenic dynamics also have been studied as a potential concern (Ryu et al., 2010). shelter? Adaptive management can play a role in mitigating any adverse effects on wildlife through exposure via drinking. Toxicity from salt exposure is possible. Marine sulphur emissions. McCabe, T.R. <p>The environment helps the life cycle of the organism to continue.</p>. 2009a. People have expressed concerns regarding the release of genetically engineered microorganisms, ranging from impacts of large-scale releases (and failure of control mechanisms) on biodiversity to ecosystem and evolutionary processes (Hagedorn and Allender-Hagedorn, 1997). Gerba. Algal-bacterial processes for the treatment of hazardous contaminants: A review. 1996. Limiting Factors. The United States and other countries are pursuing ocean current energy . West Nile virus: Pending crisis for greater sage-grouse. However, uncertainties are too great to quantify this probability or to calculate net GHG emissions under these assumptions. Emissions of greenhouse gases from ponds constructed for nitrogen removal. This is a pretty broad question, but I'll try to provide some answers to what I think you are asking about. Found insideAll we can do at present is to admit that border-line organisms exist between the distinctly pathogenic and definitely nonpathogenic groups. If the normal life cycle of the bacterial cell, as some still believe, consists mainly of an ... LCA results for net GHG emissions for algae biofuel production vary from a net negative value (that is, a carbon sink) to positive values substantially higher than petroleum gasoline (Table 5-4). 2003. Solon. The effect of organism-environment relationships is not merely one of life or death, but variability in the organism's response to environmental forces. EPA (U.S. Environmental Protection Agency). Attraction to algal ponds could be a major problem if they contain toxic chemicals or pathogens at harmful concentrations. ____________. 2009. Schmidtmann, R.T. Mayer, C.Y. In 2008, U.S. farmers planted more than 32 million acres of Monsanto’s “triple-stack” genetically engineered corn, and it is estimated that this number will increase to approximately 56 million acres by 2015 (Kaskey, 2009). GHG credit from replacing corn with oil-extracted algae as a feedstock for ethanol results in a negative carbon balance. Hello televiewers especially kids and parents welcome to AGHAMAZING T.V. Kung nagustohan mo ang videong ito, iclick lamang ang subscribe button para sa ating susunod na lesson. that use terrestrial crops as feedstock (Beeman, 2007; Smith, 2008; EPA, 2009b; Buntjer, 2010; Meersman, 2010; O’Sullivan, 2010). Moreover, there is growing societal concern about the spatial and temporal scales of some types of conversions, such as deforestation and urbanization.

Washington, DC: American Public Health Association, American Water Works Association, and Water Environment Federation. These usually are measured quantities, and baseline levels and natural variability also can be measured. Where important or rare ecosystem services are provided by the baseline land use, a measure of those services could serve as a sustainability indicator for algal biofuels. One category of such metrics would be diagnostic traits for invasiveness. There is evidence that nuclear genes encoding chloroplast proteins have been transferred from an alga to an ascoglossan sea slug that consumes the algae (Pierce et al., 2003). Avoiding pastureland and areas of high biodiversity or recreational value also would eliminate some of the sustainability concerns associated with commercial development of algal biofuels. Parasitic disease - Parasitic disease - Parasite life cycles: All parasites have a life cycle that involves a period of time spent in a host organism and that can be divided into phases of growth, reproduction, and transmission. In our oceans, there are a number of environmental conditions that affect the growth, survival and productivity of marine organisms. Seasonal variations in nitrate leaching in structured clay soils under mixed land-use. Share a link to this book page on your preferred social network or via email. These conditions might prevail in some ponds with substantial biomass or other organic matter in the sediment. In addition to avoiding collisions, advanced air traffic control systems make it easier to identify and dodge inclement weather. • Number of vertebrate fatalities from drinking from algal ponds per year (direct measure). Bioresource Technology 73(3):263-272. 2012. 2001. 2000. Suter, II. Found inside – Page iThe purpose of this regional workshop in the Southeast was to broaden the environmental health perspective from its typical focus on environmental toxicology to a view that included the impact of the natural, built, and social environments ... National Algal Biofuels Technology Roadmap. Estimates of global warming emissions for open-loop systems are approximately 0.1 pounds of carbon dioxide equivalent per . Moreover, because harvested algal biomass contains the nutrients that were absorbed during cellular growth, wastewater-integrated systems can perform an important nutrient removal service. Land-use change is not consistently proposed as a criterion for sustainability, even though it often is considered a factor influencing aspects of the sustainability of biofuel (for example, GHG emissions, biodiversity, water quality, and soil quality).

Environmental evaluation project: frog pond habitat -students answer a short quiz about how organisms are adapted to their environment, then explore a pond environment. Regulation and compliance assurance would address concerns about release of harvest water. Oglesby, R.T. 1977. For example, converting from annual-crop production to perennial-crop production can enhance carbon storage on that piece of land (Fargione et al., 2008). Therefore, potential risks from using each type of produced water need to be identified so that adequate containment and mitigation measures can be implemented in cultivation and processing. Carrick, H.J. Invasiveness varies in different natural environments, and site-specific assessments might be necessary to reduce risks of invasion. (2002) and Gerber and Hatch (2002). Baskaran, M.E. More information is needed on potential relationships between traits that are targets for modification and behavior of cyanobacteria or microalgae that could alter rates of release, survival, growth, transport, genetic exchange, and ecological or human health effects. 1997. USDA-RD (U.S. Department of Agriculture Rural Development). Placing systems well away from waterways and wetlands where pond algae may thrive could reduce or minimize the likelihood of blooms of released species. Moeller, P.D.R., K.R.

Dorevitch, S., M. Doi, F.C. In addition to protecting the aircraft, this significantly shortens the delays that passengers would otherwise experience. Moreover, removing bicarbonate pumps, which increases fitness in the cultivation environment with high CO2, could reduce the competitive ability to take up inorganic carbon in natural waters (Sayre, 2011). The basis of mitigation is that carbon emissions from combusting a biofuel are cancelled by the corresponding capture in photosynthesis. All the organisms possess the ability to adapt to the environment through a process of biological variation. Transactions of the American Microscopial Society 86:497-498. It refers to the region of the atmosphere and surface of the earth occupied by living organisms. Fargione, J.E., T.R. Thus, monitoring of toxic compounds in the culture media is important. Curtis. 2008. Bloom. However, concerns about genetically engineered microorganisms in surveys and in the popular press have related more to environmental effects than to health or ethical issues (Hagedorn and Allender-Hagedorn, 1997), and these concerns might be expected to dominate for microalgae. The data gaps for estimating energy use and the method gaps in reducing energy use discussed in the section Energy (Chapter 4) apply to reduction of GHG emissions. 2011. Productivity and net recruitment, Total range (presence/absence) Trends in number of individuals in each subpopulation, Age structure of population Survival of some pathogens from biosolids in soil has been studied (Zerzghi et al., 2009), but the survival of human and animal pathogens in algal biofuel cultures is only beginning to be investigated. For agricultural evaporation ponds, the primary wildlife concern has been the concentration of selenium (Evaporation Ponds Technical Committee, 1999); its environmental transformations and accumulation have been studied (Gao et al., 2007). Oil can also smother some small species of fish or invertebrates and coat feathers and fur, reducing birds' and mammals' ability to maintain their body temperatures. Air quality issues associated with biofuel production and use. Mercury and methylmercury in individual zooplankton—implications for bioaccumulation. 2011. Hoffmann, L. 1996. To put this into context, estimates of life-cycle global warming emissions for natural gas generated electricity are between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt-hour and estimates for coal-generated electricity are 1.4 and 3.6 pounds of carbon dioxide equivalent per kilowatt-hour . Some algal biofuel companies, such as Algenol and Synthetic Genomics, are conducting research on genetically engineered organisms for algal biofuel production (Gressel, 2008). CARB (California Air Resource Board) 2010. Moreover, blooms cannot be predicted with accuracy in natural environments (Carrick, 2011), and this likely applies to open biofuel cultivation systems as well. 2008. Environmental Toxicology and Chemistry 23(3):798-811. Cincinnati, OH: National Center for Environmental Assessment. Impossible unless accidental breach of photobioreactor. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change. Genetic exchange might lead to unexpected effects. Martinez, M.E., S. Sanchez, J.M. 2009. Aviation safety is important because there are lives involved in every operation of aircraft. These indicators are standard measures for quality of water and wastewater (Eaton et al., 2005). Quantifying water losses from raceways, ponds, or photobioreactors would indicate whether repairs of small leaks are necessary. Science 329(5993):796-799. bValue taken from Lenzen and Murray (2003) and can represent areas between algal biofuel facilities, where grazing may occur.

(1957) reported average NH4+ sludge in the range of 1600 to 1850 milligrams per liter for anaerobic digestion of algae, which is comparable to some of the high values reported for piggery waste (Sukias and Tanner, 2005; Sukias and Craggs, 2011). Scientific American 300(6):54-49. Zuo, Z.J., Y.R. Local terrestrial vegetation might take up some of the culture media released through seepage. The ultimate level of nutrient removal benefit may depend on the level of wastewater treatment that occurs prior to nutrient uptake in the algal cultivation systems and on the chemical and ecological conditions that exist in the wastewater-fed production system. International Journal of Life Cycle Assessment 15(7):704-714. Massey, J.J. Hanten, and N.E. Triemer. The spatial and temporal scales of land-use change would be commensurate with those of land use.

Open-pond algae cultivation also can be sited in locations that are not prone to hurricanes or away from lakes and streams. EPA established emission standards for tailpipe emissions of CO, hydrocarbons, NOx, and particulate matter to which vehicle manufacturers and refiners have to comply (EPA, 2009a). Environmental Science and Pollution Research 10(2):126-139. Standard Methods for the Examination of Water and Wastewater, 21st ed. Expected reductions in hydrocarbon and CO emissions. Are we recovering? 2000. DOE (U.S. Department of Energy). Foley, T. Holloway, C. Monfreda, N. Ramankutty, and D. Zaks. 2012. In contrast, if the algae cultivation ponds are installed on degraded land that is not storing much carbon, immediate emissions from the conversion will be minimal. Recent horizontal intron transfer to a chloroplast genome. Mack, and P.J. Snow et al. © 2021 National Academy of Sciences. Whether exposure to genetically engineered organisms or genetic exchange with these organisms poses any potential hazards depends on the particular traits of the organism (Snow et al., 2005). Direct land-use change occurs within the biofuel production pathway when land for one use is dedicated for biofuel production. Harm to the coral or other animals from acidification could have ripple effects on the entire ecosystem. These include creating new or more effective pathogens, affecting nontarget species, disrupting biotic communities and ecosystems, reducing biodiversity or species-genetic diversity, or degrading valuable biological resources, many of which are discussed in the section on invasive species. of both is neccessary. 15. Journal of Experimental Marine Biology and Ecology 405(1-2):111-119. 1995. It is the public. As with production and use of any fuels, aspects of biofuel production and use have benefits and adverse effects.This chapter discusses potential environmental effects from the production and use of algal biofuels, the potential influence of perceived or actual impacts on societal acceptance, and some of the health impacts potentially emanating from the specific . British Food Journal 97(8):31-36. Kjelmyr. Philosophical Transactions of the Royal Society B-Biological Sciences 352(1350):159-168. Several traits of algae for biofuels may be modified through genetic engineering methods. They speculated that oxidation of ammonium (NH4) by bacteria was the likeliest N2O-generation pathway under the observed aerobic conditions. Thus, invasive species can affect community composition and ecosystem processes (Strayer et al., 2006). Nyeko, J.I. 2012. ____________. Howe, S.A. Scott, and A.G. Smith. The potential for accidental release of cultivation water exists; for example, clay or plastic liners could be breached through normal weathering or from extreme weather events, some of which are predictable. 1994. Many algal species including cyanobacteria, diatoms, and chlorophytes can bioconcentrate heavy metals (Watras and Bloom, 1992; Vymazal, 1995; Mathews and Fisher, 2008). Yet the life cycle of an insect is very different from the life cycle of a mammal or a reptile. Food-miles and the relative climate impacts of food choices in the United States. Land-use changes play a role in the sustainability of algal biofuel development because of associated environmental effects, such as net GHG emissions, changes in biodiversity, and changes in ecosystem services such as food production. Nixon, S., B. Buckley, S. Granger, and J. Bintz. 2009. How does human factor affects aviation safety? The survival rate of a genetically engineered microalga or cyanobacterium will be determined by a combination of the species identity, the genetic modification(s), and the environment to which it is released. Applied Energy 88(10):3280-3285. Lane. Ecology 70(2):298-315. Analytical methods for detecting low densities of pathogens have not been sufficiently developed and tested to be recommended (EPA, 2011b). The environment furnishes matter and energy to main- tain the activities of each system and a considerable quan- tity. 2005. Adaptation may differ among different species but they have the same objective, i.e. Any potential indicators would have to be tested in algal ponds or photobioreactors for potential relationships with pathogen levels. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. New York: Chapman and Hall. 2005. Patrick, M.L., and T.J. Bradley. Other odorous compounds are associated with the decay of algae under anaerobic conditions where bacteria break down the organic material and produce hydrogen sulfide and NH3, both of which have a strong odor. Although passive processes (for example, solar drying) reduce air quality impacts compared to active processes that generate dust or increase volatilization rates, they are not practical solutions at large scale. Stage-3: Animals exhale Carbon dioxide back into the atmosphere which is again used by the plants during photosynthesis. Ginnebaugh, D.L., J. Liang, and M.Z. Pienkos. Concerns over genetically engineered algae and perceptions of risks associated with introducing nonnative species into new geographies will need to be addressed. Marine Ecology-Progress Series 81(2):163-178. The services of pastures, rangelands, and coastal waters that might be displaced by feedstock production facilities would be important to quantify. Environmental evaluation project: frog pond habitat -students answer a short quiz about how organisms are adapted to their environment, then explore a pond environment. 2006. $3.00. The steps involved in the oxygen cycle are: Stage-1: All green plants during the process of photosynthesis, release oxygen back into the atmosphere as a by-product. In advanced wastewater treatment, phosphorus typically is either chemically precipitated using aluminum- or iron-based coagulants to form an insoluble solid, or it is stripped from the water by microbial activity (EPA, 2007). Information and data gaps include the relationship between particular drying technologies and the types and concentrations of particulates released, releases of solvents during extraction, likely concentrations of NH3 in air during anaerobic digestion, and chemicals potentially released during pyrolysis. Qualitative metrics that are related to invasiveness, but not necessarily diagnostic, include: • Wide habitat tolerances, for example, tolerances for temperature, light, and nutrients. Other concerns regarding genetic technologies relate to the unnaturalness of organisms (Tenbult et al., 2005; Connor and Siegrist, 2011); these cannot be abated through technical mitigation. Some of these are summarized in Wedding and Crawford-Brown (2007) and would be appropriate where algal biofuel production is sited on brownfields.

Problem Formulation for Human Health Risk Assessments of Pathogens in Land-applied Biosolids. The taxonomic identities and abundances of pathogens in biosolids (and by extension, wastewater) are determined by the incidence of infection within the wastewater-generating community and the particular wastewater treatment process used (Straub, 1993; EPA, 2011b). Converting crop lands to new crops (algal biofuels) also will require new ownership or a willingness on the part of farmers to grow a new commodity. Buikema, and R. Haselkorn. Accessed July 20, 2012. • Mosquitoes are vectors for numerous human infectious diseases in the United States, such as Eastern equine encephalitis, La Crosse encephalitis, St. Louis encephalitis, West Nile virus, Western equine encephalitis, and Dengue fever (recently reported in Florida). Effects of Drought on the Environment . 2008. 2011. Ecology 78(1):272-282. Large-scale algae cultivation requires the provision of large quantities of nutrients, especially nitrogen and phosphorus, to ensure high yield (see section Nutrients in Chapter 4). Social acceptability of gene technology depends on trust (Siegrist, 2000). One of the major considerations when arguing against the use of GMO products is the potential for .
