Modelling the Current and Future Pollutant Emission from Non-Road Machinery: A Case Study in Shanghai

Aerosol and Air Quality Research, 2023
With the effective control of air pollutants from industrial sources and motor vehicles, non-road machinery has become the major pollutant source with a total emission accounting for more than 65% of non-road mobile sources in China. However, few efforts

Biomarkers of Environmental Pollutants [PDF]

BioMed Research International, 2014
Thousands of pollutants enter daily into environment and exert various kinds of stress on organisms and ecosystems. Risk assessment of these pollutants to organisms and ecosystems is challenging because of diversities in chemical nature and mode of toxicity of the pollutants as well as variation in sensitivities of the organisms exposed to the ...
