Residual additives in marine microplastics and their risk assessment – A critical review

Marine Pollution Bulletin, Journal Year: 2022, Volume and Issue: 177, P. 113467 - 113467

Published: March 17, 2022

This review summarizes the current state of knowledge regarding risk assessment plastic-associated residual additives, i.e. monomers, degradation products and in marine environment, also considering effects weathering bioavailability. Experimental studies have found a number organic metal additive compounds leachates from plastics, analysis weathered plastic particles, such as polyethylene, polypropylene polystyrene particles sampled on beaches shorelines, has identified flame retardants, plasticizers, UV stabilizers antioxidants. While transfer e.g. PBDEs to organisms upon ingestion been demonstrated, uptake bioaccumulation chemicals are inconclusive. Studies hazard assessments few, focus monomers and/or limited high concentration phthalates retardants. The results vary between low, moderate risks specific not necessarily consistent for same compound. Given large potentially introduced into environment with challenges associated correct quantification exposure concentrations toxicity thresholds, question arises whether new concepts may be needed.

Enabling a circular economy for chemicals in plastics

Current Opinion in Green and Sustainable Chemistry, Journal Year: 2021, Volume and Issue: 31, P. 100513 - 100513

Published: May 7, 2021

Enabling a circular economy for plastics in Europe and beyond is an ambitious goal. To reach fully closed loop, numerous challenges knowledge gaps need to be overcome. This review provides list of more than 6000 chemicals reported found overview the assessing their impacts on environment human health along life cycle plastic products. We further identified 1518 plastic-related concern, which should prioritized substitution by safer alternatives. At last, we propose five policy recommendations, including global overarching regulatory framework related chemicals, support target 12.4 UN Sustainable Development Goals.

Long-term adverse effects of microplastics on Daphnia magna reproduction and population growth rate at increased water temperature and light intensity: Combined effects of stressors and interactions

The Science of The Total Environment, Journal Year: 2021, Volume and Issue: 784, P. 147082 - 147082

Published: April 15, 2021

In many ecosystems, the zooplankton community has been pressured simultaneously by microplastic pollution and alterations resulting from global climate changes. The potential influence of light intensity rise (from 10,830 lx to 26,000 lx) water temperature 20 °C 25 °C) on long term-toxicity microplastics (MPs) Daphnia magna were investigated. Three 21-day laboratory bioassays with model MPs (1–5 μm diameter) carried out at (i) °C/10830 lx, (ii) °C/26000 (iii) lx. each bioassay, one control (no MPs) three MP concentrations (0.04, 0.09, 0.19 mg/L) tested. all bioassays, caused parental juvenile mortality, reduced somatic growth, reproduction population growth rate.

Production, Use, and Fate of Phthalic Acid Esters for Polyvinyl Chloride Products in China

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(20), P. 13980 - 13989

Published: Oct. 7, 2021

Phthalic acid esters (PAEs) are the most common plasticizers, approximately 90% of which used in polyvinyl chloride (PVC) products, but they also endocrine disruptors that have attracted considerable attention. The metabolism PAEs PVC products China from 1958 to 2019 was studied using dynamic material flow analysis. results showed total consumption 29.2 Mt past 60 years. By 2019, in-use stocks were 5.0 Mt. Construction materials always leading position with respect and PAEs. A PAE loss 22.7 generated, 68.0% remained waste distributed landfills (50.1%), storage sites (5.5%), environment (44.4%), 12.4% eliminated during incineration open burning, 19.6% emitted into environment. From 496.4, 55.6, 3905.0 kt water, air, soil, respectively. use treatment stages contributed 79.3 19.9% emissions life cycle, This study systematically analyzed at national level over a long-time span, providing useful information on cycle management

Occurrence and mass flows of contaminants of emerging concern (CECs) in Sweden's three largest lakes and associated rivers

Chemosphere, Journal Year: 2022, Volume and Issue: 294, P. 133825 - 133825

Contaminants of emerging concern (CECs) are a in aquatic environments due to possible adverse effects on the environment and humans. This study assessed occurrence mass flows CECs Sweden's three largest lakes 24 associated rivers. The distribution 105 was investigated, comprising 71 pharmaceuticals, 13 perfluoroalkyl substances (PFASs), eight industrial chemicals, four personal care products (PCPs), parabens, two pesticides, other (mostly anthropogenic markers). is first systematic main one report environmental concentrations chemicals tributyl citrate acetate 2,2'-dimorpholinyldiethyl-ether. ∑CEC concentration generally higher river water (31-5200 ng/L; median 440 ng/L) than lake (36-900 190 ng/L). At urban sites, seasonal variations were observed for PCPs also antihistamines, antidiabetics, antineoplastic agents, antibiotics, fungicides. CEC load 180 g/day (range 4.0-4300 g/day), with total 5000 Lake Vänern, 510 Vättern, 5600 Mälaren. All used as drinking reservoirs, so further investigations impact ecosystem human health needed.
