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

open access: yesAerosol 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

Estrogen as an Environmental Pollutant [PDF]

open access: yesBulletin of Environmental Contamination and Toxicology, 2016
The paper ‘‘Estrogen as an Environmental Pollutant’’ appeared in the Bulletin of Environmental Contamination and Toxicology in 1993 (Shore et al. 1993). At the time it was one of the first papers to suggest that hormones excreted into the environment by humans and animals were present in sufficient quantities to disrupt the environment.

Fate of environmental pollutants [PDF]

open access: yesWater Environment Research, 2019
AbstractThis annual review covers the literature published in 2018 on topics related to the occurrence and fate of environmental pollutants in wastewater. Due to the vast amount of literature published on this topic, we have discussed only a portion of the quality research publications, due to the limitation of space.

Biomarkers of Environmental Pollutants [PDF]

open access: yesBioMed 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 ...
