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.

Advantages
To effectively budget for a new roof, first determine the total square footage of your roof. For a simple gable roof, you can multiply the length by the width. For more complex shapes, it’s wise to consult a roofing professional for an accurate measurement. Once you have the square footage, divide it by 100 to find the number of squares needed.
Rolled asphalt roofing is versatile and can be used in a variety of scenarios. It is most commonly used for low-slope or flat roofs. This application is especially prevalent in commercial buildings, where a low-slope design often makes traditional shingles impractical.

The primary advantage of green roof shingles lies in their ability to reduce the urban heat island effect, a phenomenon where urban areas become significantly warmer than their rural surroundings due to human activities. Traditional roofs absorb and retain heat, leading to increased energy consumption for cooling during hot months. In contrast, green roofs, with their vegetation, provide natural insulation and cooling, leading to reduced air conditioning costs.
Next, assess the current condition of your roof. If you’re replacing an old roof, you may need to remove the existing shingles. Check for any damage to the roof deck, as repairs might be necessary before proceeding. Make sure the surface is clean and dry to promote proper adhesion of the shingles.
