Yu Z, Loewen M, Zhou Y, Guo Z, Baki A, Zhang W
Environ Sci Technol . 2025 Jan; 59(3):1835-1843. PMID: 39817418
The ubiquitous distribution of microplastics (MPs) in aquatic environments is linked to their transport in rivers and streams. However, the specific mechanism of bedload microplastic (MP) transport, notably their stochastic...

Yu Z, Loewen M, Guo S, Guo Z, Zhang W
Environ Sci Technol . 2023 Jul; 57(30):11259-11266. PMID: 37475129
Microplastics (MPs) can be sheltered by bed grains, resulting in a higher threshold of mobilization compared with those moving on a smooth bed. Only one formula considering the sheltering effects...

Yu Z, Yao W, Loewen M, Li X, Zhang W
Environ Sci Technol . 2022 Oct; 56(20):14498-14506. PMID: 36197018
The incipient motion threshold of microplastics (MPs), defined as the condition that is just sufficient to initiate MP movement, is key to assessing the transport and fate of MPs in...

Hendrickx C, Bell P, Pittman M, Milner A, Cuesta E, OConnor J, et al.
Biol Rev Camb Philos Soc . 2022 Jan; 97(3):960-1004. PMID: 34991180
Modern birds are typified by the presence of feathers, complex evolutionary innovations that were already widespread in the group of theropod dinosaurs (Maniraptoriformes) that include crown Aves. Squamous or scaly...

Xiang Y, Zhang T, Liu J, Wan X, Loewen M, Chen X, et al.
Environ Pollut . 2021 Aug; 285:117686. PMID: 34380235
Atmospheric aerosols play a crucial role in climate change, especially in the Himalayas and Tibetan Plateau. Here, we present the seasonal and diurnal characteristics of aerosol vertical profiles measured using...

Wu G, Wan X, Ram K, Li P, Liu B, Yin Y, et al.
Environ Pollut . 2019 Nov; 257:113616. PMID: 31761583
Brown carbon (BrC) has been proposed as an important driving factor in climate change due to its light absorption properties. However, our understanding of BrC's chemical and optical properties are...

Wan X, Kawamura K, Ram K, Kang S, Loewen M, Gao S, et al.
Environ Pollut . 2019 Jan; 247:216-228. PMID: 30677666
Biomass burning (BB) is one of the largest sources of carbonaceous aerosols with adverse impacts on air quality, visibility, health and climate. BB emits a few specific aromatic acids (p-hydroxybenzoic,...

Ryu M, Jha A, Ojo O, Mahood T, Basu S, Detillieux K, et al.
Am J Physiol Lung Cell Mol Physiol . 2014 Sep; 307(10):L765-74. PMID: 25217661
Emerging epidemiological evidence reveals a link between lung disease and exposure to indoor pollutants such as perfluorinated compounds (PFCs). PFC exposure during critical developmental stages may increase asthma susceptibility. Thus,...
