The lack of clear regulations and controls explains that P25TiO2NPs are still found in many of the commercialized sunscreens in the market. Some of them are coated to reduce the photoactivity of the anatase form, which is known to be responsible for tissue damage, but not enough studies were made on these coated forms. The anatase photoactivity could trigger the production of reactive oxygen species (ROS) generation, as it was stated before. The ROS are chemically reactive species containing oxygen, such as peroxides, superoxide, hydroxyl radical, and singlet oxygen. They are regularly produced in the biological milieu and counterbalanced by physiological antioxidant defense mechanisms. However, an abrupt increase of ROS may result in non-reversible damage to the skin cells. The effects of coated and uncoated P25TiO2NPs need therefore to be studied, and articles on this topic present different conclusions. [11], [12], [13] Recent literature on this topic found that TiO2NPs inhalation provokes serious genotoxicity and DNA damage [14], [15], [16], [17]. On the other hand, some studies in rats have reported no significant harm to genetic material [18], [19], [20], [21], [22].
Titanium dioxide (TiO2) is commonly applied to enhance the white colour and brightness of food products. TiO2 is also used as white pigment in other products such as toothpaste. A small fraction of the pigment is known to be present as nanoparticles (NPs). Recent studies with TiO2 NPs indicate that these particles can have toxic effects. In this paper, we aimed to estimate the oral intake of TiO2 and its NPs from food, food supplements and toothpaste in the Dutch population aged 2 to over 70 years by combining data on food consumption and supplement intake with concentrations of Ti and TiO2 NPs in food products and supplements. For children aged 2-6 years, additional intake via ingestion of toothpaste was estimated. The mean long-term intake to TiO2 ranges from 0.06 mg/kg bw/day in elderly (70+), 0.17 mg/kg bw/day for 7-69-year-old people, to 0.67 mg/kg bw/day in children (2-6 year old). The estimated mean intake of TiO2 NPs ranges from 0.19 μg/kg bw/day in elderly, 0.55 μg/kg bw/day for 7-69-year-old people, to 2.16 μg/kg bw/day in young children. Ninety-fifth percentile (P95) values are 0.74, 1.61 and 4.16 μg/kg bw/day, respectively. The products contributing most to the TiO2 intake are toothpaste (in young children only), candy, coffee creamer, fine bakery wares and sauces. In a separate publication, the results are used to evaluate whether the presence of TiO2 NPs in these products can pose a human health risk.
A study published in the Journal of Agricultural and Food Chemistry in 2019 sought to examine the effects of titanium dioxide on intestinal inflammation. Researchers did this by feeding rats titanium dioxide nanoparticles and found that, after the course of two to three months, the animals had lower body weights and induced intestinal inflammation. The researchers also found the nanoparticles altered gut microbiota composition and aggravated chronic colitis. The rats also experienced reduced populations of CD4+T cells (which are cells that help organize immune responses by prompting other immune cells to fight infection), regulatory T cells, and white blood cells in mesenteric lymph nodes. The researchers wrote: “Dietary TiO2 nanoparticles could interfere with the balance of the immune system and dynamic of gut microbiome, which may result in low-grade intestinal inflammation and aggravated immunological response to external stimulus, thus introducing potential health risk.”
Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). As a white pigment, it acts as a cost-effective alternative for TiO2. Some of the properties of Lithopone include high brightness and performance under UV exposure. Lithopone requires less wetting agent to achieve optimum wetting of its surface. It is commercially graded on the basis of amount of ZnS. Its grades include 28%, 30%, and 60% ZnS. As a comparatively inexpensive white pigment, Lithopone is presently used in various paint formulations, road marking paints, jointing compounds, and putties.
Titanium dioxide is one of the most widely used white pigments, often used to add whiteness and brightness to products. It is used in the production of paints, coatings, plastics and other products to provide a white color or opacity.
In recent years, electric scooters (e-scooters) have become a progressively popular mode of transportation, providing an eco-friendly alternative for commuting in urban environments. As with any vehicle, the performance and reliability of e-scooters depend on numerous components, one of which is the timing belt. Among various options available, the 535-5M-15 timing belt stands out as a crucial part that enhances the functionality and longevity of e-scooters.

Honda vehicles are known for their reliability and longevity, and the ribbed belt plays a significant role in this reputation. A functioning ribbed belt ensures that all the vital accessories run smoothly, contributing to the overall performance of the vehicle. For instance, a properly functioning alternator provides the electrical power necessary for lights, ignition, and other electronic components. The power steering pump ensures ease of maneuverability, while the water pump plays a critical role in maintaining optimal engine temperatures.
Toothed belts, also known as timing belts, are essential components in a wide range of mechanical systems. These belts are designed with notched teeth that interlock with pulleys, allowing for precise timing of movements in engines and machinery. Understanding how toothed belts work, their applications, advantages, and maintenance can help to appreciate their significance in various industries.
Furthermore, the maintenance timelines for these belts differ. The fan belt may require more frequent inspections but can often be replaced with relative ease. The timing belt, however, requires a more meticulous approach, and replacing it typically involves more labor and higher costs due to its location and the complexity of the task.
