The skin of an adult person is, in most places, covered with a relatively thick (∼10 μm) barrier of keratinised dead cells. One of the main questions is still whether TiO2 NPs are able to penetrate into the deeper layers of the skin. The majority of studies suggest that TiO2 NPs, neither uncoated nor coated (SiO2, Al2O3 and SiO2/Al2O3) of different crystalline structures, penetrate normal animal or human skin. However, in most of these studies the exposures were short term (up to 48 h); only few long-term or repeated exposure studies have been published. Wu et al.83 have shown that dermal application of nano-TiO2 of different crystal structures and sizes (4–90 nm) to pig ears for 30 days did not result in penetration of NPs beyond deep epidermis. On the other hand, in the same study the authors reported dermal penetration of TiO2 NPs with subsequent appearance of lesions in multiple organs in hairless mice, that were dermal exposed to nano-TiO2 for 60 days. However, the relevance of this study for human exposure is not conclusive because hairless mice skin has abnormal hair follicles, and mice stratum corneum has higher lipid content than human stratum corneum, which may contribute to different penetration. Recently Sadrieh et al. performed a 4 week dermal exposure to three different TiO2 particles (uncoated submicron-sized, uncoated nano-sized and coated nano-sized) in 5 % sunscreen formulation with minipigs. They found elevated titanium levels in epidermis, dermis and in inguinal lymph nodes, but not in precapsular and submandibular lymph nodes and in liver. With the energy dispersive X-ray spectrometry and transmission electron microscopy (TEM) analysis the authors confirmed presence of few TiO2 particles in dermis and calculated that uncoated nano-sized TiO2 particles observed in dermis represented only 0.00008 % of the total applied amount of TiO2 particles. Based on the same assumptions used by the authors in their calculations it can be calculated that the total number of particles applied was 1.8 × 1013 /cm2 and of these 1.4 x107/cm2 penetrated. The surface area of skin in humans is around 1.8 m2  and for sun protection the cream is applied over whole body, which would mean that 4 week usage of such cream with 5 % TiO2 would result in penetration of totally 2.6 × 1010 particles. Although Sadrieh et al.concluded that there was no significant penetration of TiO2 NPs through intact normal epidermis, the results are not completely confirmative.

Raw material costs, particularly the price of titanium ore, have a significant impact on the price of titanium dioxide. As the cost of titanium ore rises, manufacturers may pass on these increased costs to consumers, leading to higher prices for titanium dioxide. Additionally, production capacity can also affect the price per ton. When there is excess capacity, manufacturers may compete for market share by lowering prices, which can lead to lower prices for consumers.

The production process of lithopone involves a sophisticated synthesis of zinc sulfide and barium sulfate, resulting in a pigment that boasts high whiteness, opacity, and heat stability. The ratio of ZnS to BaSO4 can be adjusted to cater to specific applications, with some formulations containing up to 70% zinc sulfide and 30% barium sulfate. This flexibility makes lithopone an adaptable solution for manufacturers seeking optimal performance in their products.

  • Extra large dustbins can also play a pivotal role in promoting responsible waste disposal among community members. When waste containers are consistently filled, individuals may be less inclined to dispose of their waste responsibly. However, by providing ample space for rubbish, extra large dustbins encourage people to discard their litter properly rather than leaving it on the ground. This change in behavior fosters a culture of cleanliness and responsibility, strengthening community ties and enhancing the overall quality of life.

  • In terms of safety, telescopic security posts serve as a visual deterrent against potential threats. Their conspicuous presence signals that an area is protected, discouraging potential wrongdoers. Furthermore, unlike traditional barriers that can obstruct visibility and traffic flow, these posts maintain an unobtrusive profile when retracted, promoting an open and accessible environment.


  • From an aesthetic perspective, ground-embedded bollards can be customized to reflect the character and style of a particular area. Available in various shapes, sizes, colors, and materials, they can complement the architectural features of surrounding buildings or the natural beauty of landscapes. Artistic bollard designs can add visual interest to urban settings, turning functional elements into attractive features that enhance the appeal of public spaces.


  • Once planning is complete, the next step is excavation. The area around the existing manhole should be carefully dug out to expose the structure beneath. The depth and diameter of the excavation must allow for the proper fitting of the frame and cover. The subgrade, or the bottom of the excavation, should be firm and level. If the existing subgrade is unstable, it may be necessary to add a layer of compacted gravel to create a solid foundation.

  • If you prefer a more traditional approach, bike stands or shelves can be a great addition to your home. Bike stands can hold one or two bikes upright and come in various styles, including freestanding and foldable options. They are perfect for entryways, basements, or garages. On the other hand, adding shelves to your garage or cycling room not only provides a place to store your bike but also allows you to organize accessories like helmets, lights, and tools. This dual functionality helps keep your cycling gear in one place without creating clutter.


  • The impact of the Ankur Dustbin extends beyond just practical waste management. It serves as an educational tool, raising awareness about the importance of waste segregation among the general population. By placing these dustbins in schools, parks, and public areas, communities foster a sense of responsibility among citizens, particularly the younger generation, who are the custodians of our planet’s future. Educational programs and workshops can be organized around the usage of the Ankur Dustbin, making the process of waste management not just a chore, but an integral part of community engagement and environmental stewardship.
