Global Best Practices on Emerging Chemical Policy Issues of Concern under SAICM

This study aims to predict human exposure to pollutants and heating load in buildings by developing a numerical model coupling heat and chemical transfers in the building envelope. The study characterizes the effect of temperature and air renewal rate on chemical emissions from building materials and human exposure. The results show that increasing indoor temperature by 10°C doubles the maximum indoor air concentration of volatile and semi-volatile organic compounds, leading to increased human exposure. The study also finds that higher air renewal rates lead to smaller intake fractions of pollutants from building materials. The study highlights the need to guide early design choices towards a good compromise between human indoor exposure and heating load, especially with the increasing emphasis on energy-efficient building design.

The study examines the near-field exposures and health risks of organic chemicals in interior paints commonly used in Sri Lanka. The researchers developed mass balance-based and high-throughput models to predict chemical emissions during wet and dry phases and integrated these models into the USEtox model for health risk assessment. The models accurately predicted indoor air concentrations and drying time. They found that inhalation is the primary exposure pathway, and exposure is much higher for painters during application than for household members during use. The study identified chemicals of concern and recommended the use of protective equipment for painters and increasing air ventilation rates to reduce exposure for household members.

This report provides an overview of the current status and conditions of the Circular Economy in the electronics value chain in the Central and Eastern Europe (CEE) region, identifies key areas of concern, provides appropriate recommendations, and proposes priority actions to improve circularity of the sector. The recommendations and roadmap focus on the individual life cycle stages of the electronics value chain, as well as on aspects that cut across the value chain. The transition towards a more circular electronics sector in Central and Easter Europe (CEE) would require a holistic and coordinated approach to progress toward a more circular electronics value chain in the CEE region.
