Assessing Regional Sources of Atmospheric Polycyclic Aromatic Hydrocarbon Pollution and Associated Human Cancer Risk
Atmospheric pollution from organic matter burning poses health risks to humans across the globe, making it crucial to assess and regulate such pollution’s sources. One class of atmospheric pollutants, toxic, carcinogenic polycyclic aromatic hydrocarbons (PAHs), are globally ubiquitous chemicals of …

The Temporal and Spatial Distribution of Hydrocarbons in Atmospheric Deposition From Stations Surrounding Lower Chesapeake Bay
<p>Hydrocarbon concentrations were determined in bulk, wet, and dry deposition samples from urban and non-urban locations surrounding lower Chesapeake Bay. Mean hydrocarbon concentrations in bulk deposition samples were over three times greater at the urban station indicating a localized source. …

Development of optical based characterisation and detection methods for quantitative and qualitative assessment of phytoplankton in their natural environment.
… It is also important to monitor the effects of pollution on the environment and the algae. Today there are a variety of methods for monitoring algae and pollution in the marine environment but most of these have limitations such as cost, portability, effectiveness and sampling resolution. Most …

Characterization and comparison of microbial communities from different tourist ports in Mediterranean Sea and evaluation of applicability of bioremediation treatments
… critical environments as they can receive pollution coming from land, ships and from the port facilities themselves. Furthermore, ports are not closed systems and their pollution may impact large parts of the adjacent coastal areas. Specifically, pollution by petroleum hydrocarbons is one …

Characterisation of unresolved complex mixtures of hydrocarbons
The hydrocarbons of Recent Polluted.., sediments, in-reservoir and laboratory biodegraded crude oils, and certain petroleum products (e. g. lubricating oils) often display "humps" or Unresolved Complex Hixtures (UCHs) when analysed by gas chromatography (CC). Although widespread and often abundant, …

Recycling of domestic wastewater treated byvertical-flow wetlands for irrigating crops
… growth media. Filters contaminated with hydrocarbon were usually associated with a substantially lower Chilli marketable yield than those filters lacking hydrocarbon pollution. Chilli generations were grown successfully when using wastewater treated by constructed wetlands and organic …
