Polychlorinated biphenyls (PCBs) are a group of environmental persistent organic pollutants, which can be metabolized into a series of metabolites, including hydroxylated metabolites (OH-PCBs) in biota.
Despite the other sorts of pollutants which can be removed or handled entirely in a certain period of time, the radioactive wastes cannot be handled in the same way.
Polycyclic aromatic hydrocarbons (PAHs) are a large class of organic compounds that are composed of two or more fused aromatic rings and are ubiquitous environmental pollutants which can be toxic and carcinogenic depending on the actual compound [ 1, 2].
According to the official policy documents, the objective function of energy saving generation dispatch (ESGD) can be described as minimizing the fuel consumption f f and emissions of pollutants f e, which can be formulated by (4)–(6) according to reference [29].
In our knowledge, compared with other Ag systems, Ag/AAO SERS substrate could detect a variety of small biomolecules (adenine (A), thymine (T), cytosine (C), guanine (G), β-carotene) and water pollutants (malachite green), which can be used extensively in different fields without further labelling or modification.
Asexual propagation of these cultivars provides pollutant-sensitive and pollutant-tolerant plant material which can be grown on selected sites for observation.
The photocatalytic properties of titania nanoparticles promote the degradation of pollutants from the exposed surfaces, which can be easily washed away by rain.
This spatial variation in air pollutant concentrations in urban areas, which can be largely attributed to traffic emissions, has been documented for several pollutants, such as nitrogen dioxide, black smoke, elemental carbon, ultrafine particles, and particulate matter (PM2.5 and PM10) [ 9, 10].
An interesting alternative is the absorption of the pollutant in a solid polymer which can be used as support in a biofilter or biotrickling filter.
The association of reduced HRV in single-pollutant models with only NO2, which can be considered another marker of traffic in addition to BC, provides further support for the effects of pollution of traffic origins.
Other pollutants, after all, are essentially impurities, which can be washed from the coal or filtered out of the flue gas.
