Over the past several years, both near infrared (NIR) and mid infrared (MIR) spectroscopy have steadily gained acceptance as powerful methods for at-line and on-line analysis. These methods share the advantages of high speed, robust calibration, and low service requirements compared to more established process analytical techniques such as gas chromatography. However, despite their many similar...

The present study provides an evaluation of road traffic noise pollution in the city of Amman and its effects on residents. Statistical noise index L10(18 hr) was measured at nine different sites throughout the city of Amman. The British Calculation of Road Traffic Noise (CRTN) method was used to predict noise levels at the chosen sites. The CRTN method proved to be successful in predicting noi...

Introduction: The Moravian-Silesian Region (MSR) is heavily polluted, especially due to heavy industry and local heating, and concentrations of benzo[a]pyrene (B[a]P) are among the highest in the European Union. Methods: To verify the impact of air pollution on the health of the population in the MSR, the morbidity of children was analysed in three studies which are reviewed: 1) morbidity in ch...

We welcome the Subcommittee’s review of “Air Pollution Modelling in Hong Kong”. Hong Kong’s air quality is a topic of great public concern. The lack of progress in improving air quality has led many to question the effectiveness of our air quality management system. Most people understand that air quality modelling is important for our air quality management system because of its role in air qu...

The resource intensive human activities (such as mining and extraction of mineral oils for betterment of life and modernization of society) have increased environmental pollution several folds. Products of mining and petrochemical industries are advantageous for the modern society. But waste generated such as BTEX from such industries are carcinogenic, toxic and causes adverse effects on enviro...

Malicorium supported Ni0.5Zn0.5Fe2O4 magnetic nanoparticles were synthesized by a low-cost, simple,and environmentally benign procedure. The adsorbent was characterized by several methods includingX-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infraredspectroscopy (FT-IR). Then, the potential of malicorium supported Ni0.5Zn0.5Fe2O4 magneticnanoparticles was in...

Qualitative status of the environment is signaled by a group of indicators, known as bioindicators, several of which are responsible for showing progressive impacts of different types of pollutants. Having addressed the influence of various bioindicators in environmental pollution, it has been revealed that bioindicators are sensitive to any disturbance in any environment. With regards to the p...
