The environmental scanning electron microscope (ESEM) is a scanning electron microscope (SEM) that allows for the option of collecting electron micrographs of specimens that are wet, uncoated, or both by allowing for a gaseous environment in the specimen chamber.

An environmental impact assessment and biomonitoring scientist returning from a sampling expedition at an oil spill site on Bodo Creek in the Niger River Delta. Aquatic biomonitoring is the science of inferring the ecological condition of rivers , lakes , streams , and wetlands by examining the organisms (fish, invertebrates, insects, plants ...
The sewer carrier is supported by a series of reinforced concrete arches: There are 8 large spans, each of 81-ft 10-in (25 m.) centre to centre with a clear span of 75-ft (23 m.), and a number of smaller subsidiary arches at the eastern edge. The total length is 924-ft. (281.6 m.). Each of the arches is seated on mass concrete piers. [1]
Environmental DNA or eDNA describes the genetic material present in environmental samples such as sediment, water, and air, including whole cells, extracellular DNA and potentially whole organisms. [13] [14] The analysis of eDNA starts with capturing an environmental sample of interest. The DNA in the sample is then extracted and purified.
Earth systems engineering is essentially the use of systems analysis methods in the examination of environmental problems. When analyzing complex environmental systems, there are numerous data sets, stakeholders and variables. It is therefore appropriate to approach such problems with a systems analysis method.
The WFD requires member states to implement monitoring systems to estimate the integrity of biological stream components for specific sub-surface water categories. This requirement increased the incidence of biometrics applied to ascertain stream health in Europe [ 13 ] A remote online biomonitoring system was designed in 2006.
The sustainable water supply system is an integrated system including water intake, water utilization, wastewater discharge and treatment and water environmental protection. It requires reducing freshwater and groundwater usage in all sectors of consumption.
