Comparative toxicity of the plasticizer dibutyl phthalate to
Therefore, the acute toxic effects and underlying mechanisms of dibutyl phthalate (DBP) at different concentrations (0-20mgL -1) on two typical freshwater algae (Scenedesmus obliquus and Chlorella pyrenoidosa) were investigated. The growth of S. obliquus and C. pyrenoidosa was conspicuously inhibited by DBP exposure at 2-20mgL -1.

- Does radiation degradation of di-butyl phthalate reduce toxicity?
- Radiation degradation of DBP was effective in decreasing its toxicity. Di-butyl phthalate (DBP), a widely used plasticizer, is ubiquitous in aquatic environments due to the widespread application of plastics. Moreover, DBP is refractory and difficult to remove in biological wastewater treatment process.
- Is dibutyl phthalate toxic to algae?
- Toxic effects of dibutyl phthalate (DBP) on two fresh algae were originally compared. DBP was more toxic to C. pyrenoidosa than S. obliquus due to cell structure. DBP inhibited photosynthesis by damaging cell membranes and organelles. Increased ROS levels in algae resulted in oxidative stress and lipid peroxidation.
- Is dibutyl phthalate a teratogen?
- Dibutyl phthalate (DBP) is one of the six phthalic acid esters found on the Priority Pollutant List, which consists of pollutants regulated by the United States Environmental Protection Agency (U.S. EPA). DBP was added to the California Proposition 65 (1986) list of suspected teratogens in November 2006.
- Why is DBP more toxic to C pyrenoidosa than S obliquus?
- DBP is more toxic to C. pyrenoidosa than to S. obliquus due to their different cell structures. For both algae, DBP exposure clearly caused cell vacuolization, detachment of cell and plasma membranes, and disintegration of chloroplasts. The occurrence of DBP also inhibited photosynthesis.
- Can microorganisms biodegrade dimethyl phthalate?
- Biodegradation by microorganisms represents one route for remediation of DBP. For example, Enterobacter species can biodegrade municipal solid waste—where the DBP concentration can be observed at 1500 ppm—with a half-life of 2–3 hours. In contrast, the same species can break down 100% of dimethyl phthalate after a span of six days.
- What are the biological effects of plasticizers?
- Moreover, the paper provides novel data on the biological effects of some of these plasticizers in invertebrates, fish and amphibians. Phthalates and BPA have been shown to affect reproduction in all studied animal groups, to impair development in crustaceans and amphibians and to induce genetic aberrations.
