On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):

“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
 
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
 
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.”

Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.

  • Trench drains, also known as linear drains or channel drains, are designed to collect and redirect surface water from paved surfaces such as driveways, walkways, and parking lots. The effectiveness of these systems is largely dependent on the design and type of grate used. A 4% slope in trench drain grates refers to the gradient that allows water to flow toward the drain efficiently, preventing pooling or stagnation in high-traffic areas.


  • Tasarım açısından, bar grating’in esnekliği ve çeşitli tasarım alternatifleri sunması, mimarların ve mühendislerin yaratıcılığını artırmaktadır. Farklı aralıklarla yerleştirilen çubuklar, istenilen yük taşıma kapasitesine, estetik görünüm ve kullanım amacına göre şekillendirilebilir. Ayrıca, bar grating’in monte edilmesi oldukça kolaydır; bu da inşaat süreçlerini hızlandırmakta ve maliyetleri düşürmektedir.

  • Versatility is a hallmark of steel grating flooring. It comes in various styles, materials, and finishes, allowing businesses to select the most suitable option for their specific needs. Some common materials include galvanized steel, stainless steel, and aluminum, each providing different aesthetics and levels of corrosion resistance. The spacing of the bars can also be customized, depending on the application, be it for pedestrian walkways, vehicular traffic, or heavy machinery operations.


  • Concrete weight coating is an essential process used in the pipeline industry, primarily aimed at providing protection and stability to underwater pipelines. This method is critical for ensuring the longevity and reliability of pipelines, particularly in marine environments where external factors can significantly impact their structural integrity.
