Leachate From Expanded Polystyrene Cups Is Toxic to Aquatic Invertebrates (Ceriodaphnia dubia)
Expanded polystyrene (EPS) products and their associated chemicals (e.g., styrenes) are widespread in the marine environment. As a consequence, bans on their use for single-use packaging materials are being proposed in several municipalities. To better understand how science can inform decision-making, we looked at the available scientific literature about contamination and effects and conducte...
متن کاملLongevity and Reproduction of Ceriodaphnia Dubia in Receiving Waters
Seven-day tests with Ceriodaphnia dubia are commonly used to estimate toxicity of effluents or receiving waters but can sometimes yield no toxicity outcomes even if pollutants are present. We conducted two sets of full life-cycle tests with C. dubia to (1) determine whether tests with longer exposure periods to low concentrations of contaminants in ambient water might reveal evidence of toxicit...
متن کاملToxicity of Biosolid Elutriates from Different Wastewater Treatment Processes to Ceriodaphnia Dubia
Biosolids from wastewater treatment plants (WWTPs) have a high content of nutrients and organic matter and are used as a land fertilizer constituent. However, biosolids can contain many toxic chemicals, including heavy metals and synthetic organic chemicals. Thus, land application of biosolids may introduce these toxicants to water resources through runoff or soil leachate. The objective of thi...
متن کاملEffects of Diet on Seven-Day Ceriodaphnia dubia Toxicity Tests
The purpose of this study was to evaluate the effects of four diets on the results of seven-day Ceriodaphnia dubia toxicity tests. Survival and reproduction were used as indices to detect the sensitivity of this species to acute and chronic copper stress. All toxicity tests were conducted using the moderately hard reconstituted water recommended in 1989 by the U.S. Environmental Protection Agen...
