In some countries (Egypt for example) sewage is a valuable source of water.
This indicates that these putative transfers could have happened in some other environment in which M. smithii can co-exist with other archaea, for example, sewage waters.
For example, sewage effluent exposures produce more rapid VTG induction in rainbow trout compared with that in carp or roach; however, the effective concentration of effluent to induce VTG is essentially the same (Jobling et al. 2004; Tyler et al. 2005).
Furthermore, humans have created environments with unprecedented mixing opportunities between environmental bacteria and human pathogens in the presence of such selective agents through, for example, sewage and waste water treatment plants, chemical production factories, and the practice of spreading manure on farmland.
This is mainly because of poor health and sanitation conditions (for example, open sewage drains and unpaved roads resulting in standing rainwater).
For example, untreated sewage, domestic waste, and excessive fertilizer applications could all lead to AP accumulation in urban and suburban soils (Huang et al. [2013]).
Comparing our maximum concentrations with the maximum concentrations from other countries, for example, in sewage sludge from France Pariss), 29 times lower values for NP, ten times higher values for NP1EO, 57 times higher values for NP2EO, and 1.4 times higher values for DEHP were observed as those for Italy [17].
Philadelphia, for example, funnels sewage fees into programs that turn concrete "gray" infrastructure into absorbent systems that better handle water runoff, while Denver puts its water fees into forest conservation to keep the surrounding watershed healthy.
In Hong Kong, for example, faulty sewage works in a residential block were deemed to be the cause of a major outbreak in a residential estate (2 ).
Animal wastes are also rich in organics and high in biochemical oxygen-demanding materials (BOD); for example, treated human sewage contains 20 60 mg BOD/L, raw sewage contains 300 400 mg BOD/L, and swine waste slurry contains 20,000 30,000 mg BOD/L (Webb and Archer 1994).
Local governments might decide, for example, to site a sewage treatment plant in an adjoining but unincorporated neighborhood even when, as is often the case, no sewage service is available to the affected area.
