10Selenium is an essential trace element needed for all living organisms. Despite its
essentiality, selenium is a potential toxic element to natural ecosystems due to its …

Selenium (Se) uptake by primary producers is the most variable and important step in
determining Se concentrations at higher trophic levels in aquatic food webs. We gathered …

Mercury (Hg) is one of the few metals known to accumulate through food webs to
concentrations that are much higher in upper trophic level organisms than those in primary …

The discharge of aquaculture wastewater and the excessive selenium in aquaculture
effluent caused by selenium addition to aquatic feed are posing a serious risk for the marine …

Increasing selenium concentrations in aquatic environments downstream of mine sites is of
great concern due to selenium's bioaccumulation propensity and teratogenic toxicity …

This study evaluated the spatial variability of risks and benefits of consuming fish from humic
and clear lakes. Mercury in fish is a potential risk for human health, but risk assessment may …

Mountaintop mining (MTM) affects chemical, physical, and hydrological properties of
receiving streams, but the long-term consequences for fish-assemblage structure and …

Anthropogenic activities resulting in releases of selenium-laden waste streams threaten
freshwater ecosystems. Lake ecosystems demand special consideration because they are …

Aquatic ecosystems worldwide face growing threats from elevated levels of contaminants
from human activities. Toxic levels of selenium (Se) shown to cause deformities in birds, fish …

Despite decades of fate and effects studies, environmental selenium (Se) contamination and
management remain an issue for many freshwater systems in North America. Several …
