Microplastic abundance, distribution and composition in the Pearl River along Guangzhou city and Pearl River estuary, China.

Chemosphere, 2019
Like many urban rivers, the Pearl River in China is contaminated with microplastics. Compared with marine environments, microplastic pollution in freshwater is less understood, especially in urban rivers.

Distribution of microplastics in surface water of the lower Yellow River near estuary.

Science of the Total Environment, 2019
The composition and distribution of microplastics in surface water of the Yellow River lower reach near estuary were investigated in this work. The major shape types of microplastics can be classified to fibers, fragments and particles, and 93.12% of ...

The Modification of an Estuary

Science, 1986
The San Francisco Bay estuary has been rapidly modified by human activity. Diking and filling of most of its wetlands have eliminated habitats for fish and waterfowl; the introduction of exotic species has transformed the composition of its aquatic communities; reduction of freshwater inflow by more than half has changed the dynamics of its plant and ...

Microplastic contamination in an urban estuary: Abundance and distribution of microplastics and fish larvae in the Douro estuary.

Science of the Total Environment, 2019
Estuaries are productive environments used by many fish as nursery grounds. The initial stages of fishes are highly vulnerable to (a)biotic factors, and anthropogenic pressures, influencing fish larvae assemblages along the estuary. Microplastics (MPs

Estuaries

2020
This chapter concerns estuaries. Estuaries represent the great transition between freshwater and marine biomes, and as such they are influenced by both aquatic realms while having a distinct and exceptionally variable environment and ecology of their own.

Spatial distribution, source apportionment and risk assessment of antibiotics in the surface water and sediments of the Yangtze Estuary.

Science of the Total Environment, 2019
The "pseudo-durability" of antibiotics in estuaries is gaining increasing interest, especially in the Yangtze Estuary, a vital water supply source for the Shanghai city. To clearly describe the pollution level and risk of antibiotics in this estuary, the
