Secondary Production of Gaseous Nitrated Phenols in Polluted Urban Environments

Phytoremediation of heavy metals polluted environments

The rapid industrial development and agricultural growth and the indiscriminate production of pollutants have faced problems for human societies and the environment. Accumulation and pollution of heavy metals in the environment are the main important problems that as a result of human activities through extraction from ore and processing for various applications has led to the release of these ...

Metagenomics in Polluted Aquatic Environments

The relation between ozone, NO x and hydrocarbons in urban and polluted rural environments

Research over the past ten years has created a more detailed and coherent view of the relation between O 3 and its major anthropogenic precursors, volatile organic compounds (VOC) and oxides of nitrogen (NO x ). This article presents a review of insights derived from photochemical models and field measurements. The ozone—precursor relationship can be understood in terms of a fundamental split i...

Markedly enhanced absorption and direct radiative forcing of black carbon under polluted urban environments.

Black carbon (BC) exerts profound impacts on air quality and climate because of its high absorption cross-section over a broad range of electromagnetic spectra, but the current results on absorption enhancement of BC particles during atmospheric aging remain conflicting. Here, we quantified the aging and variation in the optical properties of BC particles under ambient conditions in Beijing, Ch...

Layered double hydroxides: Novel nanocatalysts for combustion of gaseous toluene from polluted air

The catalytic performance of Ni-Al, Mg-Al, and Co-Ni LDHs as novel nanocatalysts was evaluated in the oxidation of toluene. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The XRD and FTIR approved the structure and functional groups of the LDH, respectively. Also, the presence of cations with dif...
