Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
Drobne et al. used the terrestrial arthropod Porcellio scaber as a test organism for determining the cytotoxic effect of TiO2 NPs (anatase). The animals were exposed to TiO2 NPs of two different sizes (25 nm and 75 nm) in the concentration range 10–1000 μg TiO2/g dry food for 3 to 14 days. No adverse effects, such as mortality, body weight changes or reduced feeding, were observed. In fact, quite the opposite, an enhanced feeding rate, food absorption efficiency and increase in catalase activity were observed. The intensity of these responses appeared to be time- but not dose-dependent. It should also be noted that the concentrations tested in this study were much higher than the predicted concentration (4.8 μg/g soil) at high emission scenario of nano-sized TiO2. Using the same test organism another group showed that exposure to TiO2 NPs induced destabilization of cell membrane in the epithelium of digestive glands isolated from exposed animals. They also showed that this effect can be observed after just 30 minutes of exposure.
Manufacturers use titanium dioxide in some packaging to protect food from exposure to sunlight. Lab studies show it may also help stop bacteria from growing, and break down a gas that makes many fruits and vegetables ripen faster. That can keep products fresher and give them a longer shelf life.
Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). Titanium Dioxide (TiO2) has replaced Lithopone as a white pigment in majority applications as TiO2 is more durable. However, it is much cheaper than TiO2 and has advantages such as low binder requirement and good dispensability. As a white pigment, it can improve the substrate's weather resistance, and improve the fungicidal properties of paint formulations. Some of the major applications of Lithopone include manufacturing of paint pigments, plastic & rubber products, paper, printing inks, cosmetics, and leather & linoleum products. It is commercially available under names such as pigment white 5, Barium zinc sulfate sulfide, Becton White, C.I. 77115, Charlton White, Enamel White, and Zincolith. On the basis of content of ZnS, Lithopone is available at 28%-30% Lithopone and 60% Lithopone.
Decorative wire mesh fencing is a type of fence made from intertwined metal wires, often galvanized or coated to resist rust and corrosion. Unlike standard wire fencing, which typically emphasizes utility, decorative wire mesh offers intricate designs and patterns that enhance the overall look of gardens, yards, and patios. These fences can vary in design, with options ranging from geometric patterns to floral motifs, making them suitable for a wide range of architectural styles.
They can be customized in various sizes and shapes to fit specific site requirements, making them suitable for a wide range of applications, from small-scale landscaping projects to large-scale civil engineering works They can be customized in various sizes and shapes to fit specific site requirements, making them suitable for a wide range of applications, from small-scale landscaping projects to large-scale civil engineering worksgabion baskets for erosion control. Additionally, their permeability promotes vegetation growth, enhancing the ecological value of the area over time.

The five-strand barbed wire fence is often used in agricultural settings to keep livestock contained. The sharp barbs on the wire act as a deterrent to animals trying to escape or predators trying to enter. The five strands of wire provide added strength and security, making it difficult for animals to push their way through.
A wire mesh stone retaining wall is a structure typically used to prevent soil erosion and retain the slope of land. It is made up of wire mesh panels filled with stones or rocks, creating a sturdy and durable barrier against the forces of gravity and erosion.
