This article reports on the outcome of an African regional workshop on generating support for phasing out lead in paint. The workshop recommended a lead limit of 90 ppm. In Nigeria, the 90 ppm lead standard has been in place since 2016 and a roadmap on lead paint elimination and management has been adopted.

This article from the Journal of Exposure Science & Environmental Epidemiology notes it is not uncommon for so-called green building to meet the highest criteria for energy efficiency and be built with materials that contain chemicals hazardous to occupant health. This journal article provides key examples of how scientists have promoted healthy building practices and highlights additional research opportunities.

Per- and polyfluoroalkyl substances (PFASs) are known organic pollutants with adverse health effects on humans and the ecosystem. This paper synthesises literature about the status of the pollutants and their precursors, identifies knowledge gaps and discusses future perspectives on the study of PFASs in Africa.

Per- and polyfluorinated alkyl substance (PFAS) contamination has been found in the construction spoil of many major projects, and there is growing concern about the health and environmental implications of these “forever” chemicals. This study highlights the common issues that are associated with the management of PFAS contamination in the construction industry, and proposes a mechanism for improved regulation.

Two international Conventions from the International Labor Organization (ILO; C162 Asbestos Convention) and the UN (Basel Convention) offer governments guidelines for achieving a total asbestos ban policy, but the long-term effect of these Conventions on policy implementation remains unknown. This study assessed data on asbestos bans in 108 countries and confirms that adoption of both the C162 Asbestos Convention and the Basel Convention facilitates countries in moving towards a total asbestos ban.

This review focuses on the world’s first process for producing an aromatic polycarbonate (PC) using CO2 as starting material. The process is an example of green and sustainable chemistry as previous methods of producing PC use not only highly toxic and corrosive phosgene made from CO and Cl2 as a monomer, but also very large amounts of CH2Cl2 and water.

Plastics are used in a vast range of building components, such as seals, windows and doors, roofing, internal and external finishes, paints, panels, varnishes, stains, pipes, guttering, cables, floor coverings, membranes, formwork, supporting structures, building skins and insulation. However, their benefits come at a growing cost to the environment and public health.

The construction industry consumes 20% of all plastics and 70% of all polyvinyl chloride (PVC) produced globally each year. Exponentially greater amounts are being produced and used, with 8.3bn tonnes of virgin plastics produced worldwide between 1950 and 2017 and global output predicted to double by 2050.

The transition to sustainable construction will involve fundamental changes in the way buildings are designed, manufactured, built and operated. As society pushes up against established planetary boundaries, professionals working in the built environment need to identify how to change our practice.
