It is widely understood that stormwater drainage has a significant impact on the health of tidal creek systems via regular inputs of runoff from the surrounding watershed. Due to this hydrologic connection, contamination of the upstream dra...
Temporal Variations of O3 and NO x in the Urban Background Atmosphere of Nanjing, East China [0.03%]
中国东部南京市城市背景大气中O3和NOx的时空变化特征分析
Junlin An,Yuanzhe Shi,Junxiu Wang et al.
Junlin An et al.
Rapid economic growth has given rise to a significant increase in ozone (O3)-precursor emissions in many regions of China. An improved understanding of O3 formation in response to different precursor emissions is imperative to address the h...
Trace Elements in Sea Ducks of the Alaskan Arctic Coast: Patterns of Variation Among Species, Sexes, and Ages [0.03%]

Micah W C Miller,James R Lovvorn,Angela C Matz et al.
Micah W C Miller et al.
Climate change and increasing industrialization in the Arctic call for the collection of reference data for assessing changes in contaminant levels. For migratory birds, measuring and interpreting changes in trace element burdens on Arctic ...
Historical and Contemporary Patterns of Mercury in a Hydroelectric Reservoir and Downstream Fishery: Concentration Decline in Water and Fishes [0.03%]
水电站水库和下游渔业中的汞的历史和当代模式：水和鱼类中浓度的下降
Derek J Green,Mark Duffy,David M Janz et al.
Derek J Green et al.
Mercury (Hg) contamination can pose risks to human and animal health as well as commercial fisheries. Reservoir construction in riverine systems produces flooded conditions amenable to Hg(II)-methylating bacteria, which can transform this r...

Tissue Phthalate Levels Correlate With Changes in Immune Gene Expression in a Population of Juvenile Wild Salmon [0.03%]
组织中的酞酸盐水平与一群野鲑鱼免疫基因表达变化相关性研究
Kelly Martins,Birgit Hagedorn,Shareen Ali et al.
Kelly Martins et al.
Phthalates have detrimental effects on health and have been shown to dysregulate the immune system of mammals, birds, and fish. We recently reported that di(2-ethylhexyl) phthalate exposure reduces the abundance and inhibits the proliferati...
Manganese and Mercury Levels in Water, Sediments, and Children Living Near Gold-Mining Areas of the Nangaritza River Basin, Ecuadorian Amazon [0.03%]
厄瓜多尔亚马逊纳甘里察河流域金矿区水、沉积物和儿童的锰和汞含量水平研究
Max V González-Merizalde,José A Menezes-Filho,Claudia Teresa Cruz-Erazo et al.
Max V González-Merizalde et al.
Artisanal and small-scale gold-mining activities performed in mountain areas of the Southern Ecuadorian Amazon have incorporated several heavy metals into the aquatic systems, thus increasing the risk of exposure in populations living in ad...
