“…These observations, in combination with relatively and sustainably high EOL PVC buy-back prices offered by scrap shops, suggest that 'indirect' recycling of plasticizers via mechanical recycling of PVC has been a common practice, at least for products available on the Thai market. Similar 'indirect' additive recovery via mechanical recycling is practiced in industry, such as flame retardant recovery [78] , with some having caused exposure concerns [79][80][81][82] .…”

Polycyclic aromatic hydrocarbons (PAHs) in sediment cores from Phayao Lake were investigated in terms of their concentration, distribution, and potential effects on the environment and human health. The concentration of Σ16PAHs ranged from 77.6 to 1251.1 ng g-1. Additionally, low molecular weight PAHs (two or three fused aromatic rings) were dominant, indicating that the main source of PAHs is the incomplete combustion of organic sources. The toxic equivalent quantities (TEQs) of 16 PAHs varied from 2.67 to 155.09 ng g-1, with an average of 38.29 ± 46.69 ng g-1. Furthermore, the TEQs of 9 known carcinogenic PAHs averaged 20.77 ± 30.63 ng g-1. B[a]P had the highest TEQ, followed by D[a,h]A and B[k]F, with values of 16.93 ± 25.49, 13.89 ± 15.37 and 2.12 ± 3.64, respectively. The RQ(NCs) of ∑PAHs (RQ∑PAHs(NCs)) ranged from 1.65 × 10-4 to 6.27 × 10-1 with an average value of 1.18 × 100 ± 1.52 × 100. Moreover, RQ(NCs) was less than 1 for individual PAHs, indicating a minor risk. However, RQ(MPCs) was less than 1 for individual PAHs, indicating a moderate risk. The results showed a significant incremental lifetime cancer risk (ILCR) from sediment-bound PAHs with dermal absorption, followed by ingestion and inhalation, as the prevalent route of exposure. The measured ILCR values of all PAHs were less than 10-6 for both adults and children, which were lower than the baseline value, indicating that each PAH poses a low risk of cancer to humans. This study provides information for control and preventive actions to limit future PAH pollution in Phayao Lake.

“…The lack of information on the use and occurrence of POPs is a major challenge for enforcing control measures for POPs, particularly related to the trade of goods and waste . This is caused by a combination of factors such as a lack of legal requirements for public reporting, allowing chemical identities as confidential business information, and a lack of reporting standards and monitoring activities throughout value chains.…”

“…The sources, environmental fate and behavior, effects and control measures of POPs have strong linkages to other societal and environmental priorities such as human rights, climate change, biodiversity loss, marine plastics, and transition to a circular economy. ,,,− Understanding such linkages can help to strengthen political awareness and commitments to address POPs, and can help to enhance the effectiveness of control measures (e.g., by addressing barriers such as socio-economic pressures and drivers such as right-to-know disclosures). , Understanding these linkages can also help to identify synergistic solutions that bring cobenefits in multiple priority areas . Hence, further cross- or interdisciplinary studies are warranted to look into the links among POPs and other priority areas (including how control measures of POPs are contributing to the achievement of the 2030 Global Sustainable Development Goals, and vice versa), , methods and tools to design synergistic solutions, , and suitable indicators for effectiveness evaluation. , …”

The Stockholm Convention is key to addressing the global threats of persistent organic pollutants (POPs) to humanity and the environment. It has been successful in identifying new POPs, but its national implementation remains challenging, particularly by low-and middle-income Parties. Concerted action is needed to assist Parties in implementing the Convention's obligations. This analysis aims to identify and recommend research and scientific support needed for timely implementation of the Convention. We aim this analysis at scientists and experts from a variety of natural and social sciences and from all sectors (academia, civil society, industry, and government institutions), as well as research funding agencies. Further, we provide practical guidance to scientists and experts to promote the visibility and accessibility of their work for the Convention's implementation, followed by recommendations for sustaining scientific support to the Convention. This study is the first of a series on analyzing policy needs for scientific evidence under global governance on chemicals and waste.

Landfilling has long been the most common method of disposal for municipal solid waste (MSW). However, many countries seek to implement different methods of MSW treatment due to the high global warming potential associated with landfilling. Other methods such as recycling and incineration are either limited to only a fraction of generated MSW or still produce large greenhouse gas emissions, thereby providing an unsustainable disposal method. Here, we report the production of graphene from treated MSW, which includes treated wood waste, using flash Joule heating. Results indicate an 81-89% reduction in global warming potential compared to traditional disposal methods at a net cost of -$304 per tonne of MSW, presuming the graphene is sold at just 5% of its current market value to offset the cost of the flash Joule heating process.
