The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column  and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.

Separately, concerns have been raised about titanium dioxide impacting one's genetic code. This can be traced to a 2009 study which found that titanium dioxide nanoparticles caused DNA damage and genetic instability in mice. A 2022 study published in Food and Chemical Toxicology also raised concerns about the DNA-damaging effects of titanium dioxide as a food additive. The study noted that results evidenced a DNA-damaging effect, and added that there may also be impacts to chromosomal integrity, an indicator of cancer risk.

  • The predominant shape for manhole covers has historically been round. This is primarily due to multiple engineering advantages. Round covers cannot fall into the hole, as their diameter remains constant regardless of angle—ensuring safety and functionality. However, the emergence of square manhole designs has brought forth an interesting debate on whether a shift towards such configurations could provide additional benefits.


  • First and foremost, tree grate frames protect the root systems of trees from physical damage caused by pedestrians, vehicles, and other urban activities. Tree roots spread outward and can extend well beyond the tree canopy. When these roots are unprotected, they are susceptible to compaction, which can suffocate them and impede their growth. Moreover, physical damage caused by foot traffic can lead to injuries that may compromise the tree's health. The installation of tree grate frames mitigates these risks while allowing pedestrians to navigate through urban spaces.


  • Moreover, the integration of technology in bollard design is on the rise. Smart bollards equipped with sensors can monitor traffic patterns, detect unusual activity, or even provide real-time information to pedestrians and drivers alike. These technological advancements can optimize urban mobility and enhance safety measures, providing data that city planners can use to make informed decisions about infrastructure improvements.


  • The environmental impact of urban drainage systems is significant. Properly functioning drainage is crucial in managing stormwater runoff, which can carry pollutants into local water bodies. Round concrete drain covers can be designed to include features that promote environmental sustainability. For example, some modern designs incorporate permeable materials which allow water to drain through while filtering out debris and pollutants. This innovation helps in reducing the volume of runoff and contributes to protecting the ecosystem.

  • Civil engineers in Rome invented the concept of underground sewer to rid their cities of plagues caused by human contact with waste. Their water sources that they used for consumption were also contaminated as they served as open sewers. The underground sewers made sure that that waste stayed out of reach of humans and was deposited by these sewers further downstream. For periodic cleaning, they also provided access ways that were covered with stone lids that we call manholes today. Incidentally, these stone access way covers are still seen in Jerash, Jordan which was a Roman city in the old days.

  • In the vast network of urban infrastructure, certain elements often go unnoticed yet play an essential role in maintaining the operability and safety of our environments. Among these elements, the tank manhole cover stands out as a crucial component in various systems, particularly in water, sewage, and fuel storage.
