In a review published in 2022 in the journal Archives of Toxicologyresearchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivoex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”

The global lithopone pigment market is driven by the growth of end-use industries, particularly construction and automotive, where coatings and plastics play a significant role. Manufacturers are constantly innovating to improve the quality of lithopone pigments, focusing on enhancing their whiteness, opacity, and weather resistance. Environmental concerns have also led to the development of eco-friendly production methods, reducing waste and minimizing the environmental footprint.

  • Before diving into access panels, it’s essential to understand the role of false ceilings. A false ceiling is typically a secondary ceiling that is suspended below the actual ceiling, creating a space for electrical wiring, air conditioning ducts, and other utilities. This concealed area not only improves the aesthetics of a room by allowing for a smooth, uniform ceiling surface but also enhances acoustic performance by absorbing sound. However, the concealed systems above the false ceiling require periodic inspection and maintenance, which brings us to access panels.

  • Step 3 Prepare the Area


  • 2. Measuring and Cutting the Opening After marking the dimensions of the hatch, carefully cut the plasterboard to create an opening that fits the hatch’s frame. Ensure any electrical wiring or plumbing within the ceiling is taken into account to avoid damage.


  • Easy Installation


  • 3. Securing the Panel The access panel is then securely fitted into the opening. Depending on the model, it may attach using screws, brackets, or adhesive.
