Determination of leachate toxicity through acute toxicity using Daphnia pulex and anaerobic toxicity assays
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2017-01-01)
The municipal solid waste (MSW) of large cities, in particular in developing countries, is mainly disposed of in landfills (LFs), whose inadequate management generates the emission of greenhouse gases and the production ...
Estimating the gasoline components and formulations toxicity to microalgae (Tetraselmis chuii) and oyster (Crassostrea rhizophorae) embryos: an approach to minimize environmental pollution risk
(2007)
Even though petrochemical contamination frequently occurs in the form of oil spills, it is thought that a greater danger to coastal habitats is posed by chronic petrochemical toxicity associated with urban run-off, in which ...
Estimation of the critical effect level for pollution prevention based on oyster embryonic development toxicity test: The search for reliability
(2007)
In spite of the consideration that toxicity testing is a reduced approach to measure the effects of pollutants on ecosystems, the early-life-stage (ELS) tests have evident ecological relevance because they reflect the ...

Toxicity of three emerging contaminants to non-target marine organisms
(2019-06-01)
Coastal areas are continually impacted by anthropic activities because they shelter large urban conglomerates. Urban effluents directly or indirectly end up reaching the marine environment, releasing a large number of ...
Microscale Toxicity Identification Evaluation (TIE) for interstitial water of estuarine sediments affected by multiple sources of pollution
(2022-02-01)
Estuaries in the world are affected by different contamination sources related to urbanisation and port/industrial activities. Identifying the substances responsible for the environmental toxicity in estuaries is challenging ...
Decolorization and removal of toxicity of textile azo dyes using fungal biomass pelletized
(2018-05-21)
Abstract: Industrialization and other human impacts have placed increasing pressure on aquatic environments, with the generation of large quantities of toxic aqueous effluents containing different substances, such as ...
Acid Blue 161: Decolorization and Toxicity Analysis After Microbiological Treatment
(2016-12-01)
Concern for the incorrect disposal of potentially toxic substances in aquatic environments is growing due to adverse effects caused to the organisms exposed to them. Synthetic azo dyes are part of this group of substances, ...
Toxicity assessment of arsenic and cobalt in the presence of aquatic humic substances of different molecular sizes
(2017-05-01)
The release of contaminants in aquatic ecosystems can be influenced by humic acids. In this study, toxicity tests using environmentally relevant concentrations of arsenic and cobalt were conducted both in the presence and ...
