Environmentally relevant concentrations of microplastic particles influence larval fish ecology.
The widespread occurrence and accumulation of plastic waste in the environment have become a growing global concern over the past decade. Although some marine organisms have been shown to ingest plastic, few studies have investigated the ecological effects of plastic waste on animals. Here we show that exposure to environmentally relevant concentrations of microplastic polystyrene particles (90...
متن کاملAnalysis of Total Suspended Solids and Dissolved Oxygen Concentrations of the Algal- Bacterial Selenium Removal (ABSR) system
The Algal-Bacterial Selenium Removal (ABSR) system has been very effective at removing Selenium from agricultural drainage water that enters the water systems of the San Joaquin Valley, CA. Although selenium levels are significantly lower in the effluent of the ABSR system, Dissolved Oxygen (DO) levels in effluent water have been found to be significantly lower than normal. If DO levels dip und...
متن کاملMicroplastic exposure studies should be environmentally realistic.
To understand the impact ofmicroplastic (MP) pollution to aquatic ecosystems, it is important to identify the mechanisms of interaction with organisms. Exposure experiments, like the study of Sussarellu et al. (1) recently published in PNAS, may provide such insights. However, the results of dose–response experiments must always be interpreted in light of environmental concentrations, and the e...
متن کاملToxicity of a dissolved pyrethroid mixture to Hyalella azteca at environmentally relevant concentrations.
Use of pyrethroid pesticides, which are highly toxic to aquatic organisms, has increased substantially over the past decade. In 2006, the pyrethroid pesticides cyfluthrin and permethrin were measured in Sacramento-San Joaquin (SSJ) Delta (CA, USA) water at 5 and 24 ng/L (pptr), respectively. To elucidate any interactions between the two pyrethroids, a 10-d laboratory exposure was performed with...
متن کاملAccumulation of 2,3,7,8-tetrachlorodibenzo-p-dioxin by rainbow trout (Onchorhynchus mykiss) at environmentally relevant dietary concentrations.
Rainbow trout were fed a diet containing 1.8, 18, or 90 pg/g 3H-2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) for up to 320 d. Concentrations of TCDD were determined in muscle, liver, and ovaries at 100, 150, 200, and 250 d. Concentrations of TCDD reached an apparent steady-state concentration in liver after 100 d of exposure, whereas concentrations in other tissues continued to increase until 150...
