In an early study Jani et al. administred rutile TiO2 (500 nm) as a 0.1 ml of 2.5 % w/v suspension (12.5 mg/kg BW) to female Sprague Dawley rats, by oral gavage daily for 10 days and detected presence of particles in all the major gut associated lymphoid tissue as well as in distant organs such as the liver, spleen, lung and peritoneal tissue, but not in heart and kidney. The distribution and toxicity of nano- (25 nm, 80 nm) and submicron-sized (155 nm) TiO2 particles were evaluated in mice administered a large, single, oral dosing (5 g/kg BW) by gavage. In the animals that were sacrificed two weeks later, ICP-MS analysis showed that the particles were retained mainly in liver, spleen, kidney, and lung tissues, indicating that they can be transported to other tissues and organs after uptake by the gastrointestinal tract. Interestingly, although an extremely high dose was administrated, no acute toxicity was observed. In groups exposed to 80 nm and 155 nm particles, histopathological changes were observed in the liver, kidney and in the brain. The biochemical serum parameters also indicated liver, kidney and cardiovascular damage and were higher in mice treated with nano-sized (25 or 80 nm) TiO2 compared to submicron-sized (155 nm) TiO2. However, the main weaknesses of this study are the use of extremely high single dose and insufficient characterisation of the particles.

  • Moreover, the design and placement of rubbish bins are critical to their effectiveness. Bins must be convenient and accessible; otherwise, people may resort to disposing of garbage improperly. Cities around the world have recognized this necessity and have invested in strategically placing bins in high-traffic areas, ensuring that they are prominently visible. Additionally, modern rubbish bins come equipped with features to promote recycling, such as separate compartments for different materials. This innovation not only simplifies the recycling process but also educates the public on the importance of waste segregation.

It signals a departure from mere extravagance towards a more meaningful engagement with our environment and resources. This evolution encourages us to reflect on our values and make choices that do not solely prioritize self-indulgence but also consider the collective good.


  • A gate valve is a type of valve that opens or closes by lifting a gate out of the path of the fluid. Unlike other valves, such as globe or ball valves, gate valves are primarily designed for unidirectional flow and are best suited for applications where a straight-line flow of fluid is required. They are known for their ability to provide minimal resistance to flow when fully open. Gate valves can be constructed from a variety of materials, including cast iron, stainless steel, and brass, depending on the specific needs of the application.


  • Furthermore, welded grating is easy to install and can be quickly assembled on-site. This makes it a cost-effective option for projects that require a durable and reliable flooring solution. Whether used for industrial flooring, catwalks, or access platforms, welded grating provides a safe and stable surface for workers and equipment.

  • Gate valves are named for their unique design, which features a flat closure element, or “gate,” that can be raised or lowered to control the flow. When the valve is fully open, the gate is completely withdrawn from the flow path, resulting in minimal pressure drop and allowing for unhindered fluid movement. In contrast, when the valve is closed, the gate fits snugly against the valve seat, preventing any flow and effectively isolating sections of the pipeline for maintenance or emergencies.


  • Its design, often emblazoned with city emblems or utility logos, reflects the local character and history.
