Selenium (Se) is a contaminant of concern in many aquatic ecosystems due to its narrow
range between essentiality and toxicity in oviparous (yolk-bearing) vertebrates. The …

Daphnids were reared for 2 weeks in different concentrations of food or cadmium, and
growth and reproduction were measured as endpoints. At the end of the 14-day …

Anthropogenic activities such as the use of pesticides may affect aquatic biota populations,
due to potential agricultural runoffs or disposals. Carbendazim is one example of a widely …

The presence of multiple chemicals in aquatic ecosystems makes evaluation of their real
impact on the biota difficult. Integrated biomarkers are therefore needed to evaluate how …

Microplastic pollution, global warming, and invasive species are known threats to marine
biota, but the impact of their simultaneous exposure is still not well understood. This study …

Cellular energy allocation (CEA) is a methodology developed to evaluate the effects of toxic
stress on the metabolic balance of organisms. It consists of the integration of the energy …

Under stressful conditions, organisms often try to detoxify by mobilizing certain energy
sources with costs to various functions, eg growth or reproduction. Cellular energy allocation …

Heavy metals cause environmental pollution and produce toxic effects on organisms. Nickel
(Ni) is a common metallic pollutant of aquatic ecosystems and potentially can produce …

Cadmium as a common environmental stressor may exert highly toxic effects on herbivorous
insects. The question was whether possible elevation of an oxidative stress and imbalance …

The biggest discharge from the offshore oil industry is produced water (PW). As new
technologies emerge to remove oil from such discharges, the question remains as to the …
