Nano-sized TiO2 generally shows low or no acute toxicity in both invertebrates and vertebrates. However, exposure of Daphnia magna to 20 ppm TiO2 for 8 consecutive days was found to cause 40 % mortality. Zhu et al. showed minimal toxicity to D. magna after 48 h exposure, while upon chronic exposure for 21 days, D. magna suffered severe growth retardation and mortality. A significant amount of nano-sized TiO2 was found also accumulated in the body of the animals. Similar findings with coated nano-sized TiO2 (T-Lite™ SF, T-Lite™ SF-S and T-Lite™ MAX; BASF SE) were reported by Wiench et al. Biochemical measurements showed that exposure to TiO2 NPs induces significant concentration-dependent antioxidant enzyme activities in D. magna. Lee et al. showed that 7 and 20 nm-sized TiO2 induced no genotoxic effect in D. magna and in the larva of the aquatic midge Chironomus riparius.

  • Price trend

    The successful completion of 2022. Looking at the development of     Titanium Dioxide market in this year, from the perspective of price, according to the monitoring of bulk commodity data, the price of titanium dioxide will fall in 2022. The average price of domestic titanium dioxide at the beginning of the year was 20733.33 yuan/ton, and the average price at the end of the year was 15933.33 yuan/ton. The price fell by 23.15% during the year.

    Product quotation

    From the perspective of market development in 2022, prices in the first half of the year are basically in a stable stage, with little fluctuation, and prices in the second half of the year are in a rapid decline stage. In November, Longqi sent a letter to raise the price to stabilize the price. At this time, the price of titanium dioxide began to stabilize and stop falling.

    In the first quarter, export orders performed well, and the market confidence of titanium dioxide enterprises was good. Before the year, domestic downstream manufacturers mainly hoarded goods moderately before the year. The market rose twice, with a cumulative increase of 1.77% from January to March. The ex factory quotation of domestic rutile titanium dioxide including tax is mostly 20000-22000 yuan/ton; The ex factory quotation of anatase titanium dioxide including tax is between 18000-19500 yuan/ton. After the year, the domestic raw material sulfuric ACID price continued to rise, the enterprise cost was under pressure, and the support was strong. The titanium dioxide market confidence was fair, and the price continued to rise.

    In the second quarter, the logistics management and control and the domestic market turnover were light. Affected by logistics control and other factors, transportation is relatively difficult, market supply is shrinking, traders are unstable, and the market price declines with the focus on digesting their own inventory. The cumulative decline from April to June was 3.08%. The ex factory quotation of domestic rutile titanium dioxide including tax is between 19100-22000 yuan/ton; The ex factory quotation of anatase titanium dioxide including tax is between 17800-19000 yuan/ton. The spot market of titanium ore continued to decline, the price of sulfuric acid also continued to decline, and the cost support was weak. At the same time, the performance of the downstream terminal real estate market is poor. Under the superposition of multiple negative factors, the titanium dioxide market fell.

    In the third quarter, Longqi guided the price reduction and the titanium dioxide market fell sharply. 7-9 The cumulative decline was 19.85%. The ex factory quotation of domestic rutile titanium dioxide including tax is mostly between 15500-17000 yuan/ton; The quotation of anatase titanium dioxide is between 14500-15500 yuan/ton. Due to the limited power supply and other factors, the titanium dioxide enterprises in southwest China have reduced their production. The market price of raw sulfuric acid fell rapidly, and the cost support was weak. In addition, the domestic titanium dioxide market demand continues to be sluggish, and the manufacturer's inventory pressure is still large.

    In the fourth quarter, Dragon Enterprise sent a letter in November to promote stability. The cumulative decline was 2.55% from October 12. The titanium dioxide market is about to enter the off-season, and the demand market for coatings is tepid, especially in the northern market. In November, the group announced that the price would rise, and the prices offered by various manufacturers were flexible, so it was more meaningful to stop the decline. Most domestic rutile titanium dioxide prices are between 15000-17500 yuan/ton; The quotation of anatase titanium dioxide is about 14000-14500 yuan/ton. The price of titanium concentrate in Panxi increased. More than 20 domestic titanium dioxide enterprises sent letters to announce the increase, and the international giants Chemurs and Tronox announced the reduction of titanium dioxide production in the fourth quarter, which also benefited the domestic titanium dioxide market and stabilized the market on the whole.
