Fireworks cause short-term deterioration of air quality but related health effects remain unclear. This study evaluated the impact of typical fireworks on the chemical composition of atmospheric aerosols and their toxic effects during the Chinese Spring Festival (SF). The concentrations of firework-related water-soluble ions, metallic elements, organic carbon, and elemental carbon during the SF are 1.1-80.7, 1.8-49.1, 3.8-4.9, and 2.0-2.4 times higher than those in background period, respectively. The firework source contributes about 54.6 % to the mass of PM during the SF period based on positive matrix factorization model. The concentrations of characteristic contaminants associated with fireworks, including Ba, Cr, Ni, benzo(a)pyrene (BaP), and benzo(b)fluoranthene (BbF), exceeded the regional screening level thresholds by 2.2-29.0 times. The toxicity of eye irritation, skin sensitization, drug-induced liver injury, carcinogenicity, and ames dominated the toxicity equivalent quantities of the sixteen polycyclic aromatic hydrocarbons and are 7.5-10.3 times higher than the background levels in D-SF period. The BaP and BbF showed high percentage (60.9 %-63.1 %) among these mainly toxicities due to their relatively high mass concentrations and toxic equivalency factors. Our findings indicate that it is essential to control fireworks display activities to enhance air quality and protect human health.

Article Synopsis
- - Chlorine radicals play a crucial role in atmospheric oxidation and pollutant behavior, but their interaction with nitrogen chemistry, specifically related to nitric oxide (NO), is not well understood.
- - This research provides evidence that increased levels of NO lead to daytime breakdown of nitrate and nighttime reactions between NO molecules, resulting in higher concentrations of chlorine-containing compounds after the Chinese Spring Festival.
- - The study emphasizes that the increase in nitrogen chemistry from NO significantly boosts chlorine reactions, ultimately enhancing the levels of ozone and the overall oxidative power of the atmosphere during winter days.

Studies on media and national identity emphasize the need for a comprehensive and culturally sensitive approach to understanding the complex relationship between media and identity. This study used critical discourse analysis to examine the depiction of cultural rituals in the program and its role in forming and reinforcing national identity in China. The program, broadcast on China Central Television, showcases three traditional Chinese cultural rituals: ancestor worship, agricultural rites, and spring outings.

Environmentally persistent free radicals (EPFRs) and polycyclic aromatic hydrocarbons (PAHs) are persistent pollutants in atmospheric particulate matter that are detrimental to human health. This study collected atmospheric particulate matter during and after the spring festival travel season in Tainan, Taiwan, from various locations and analyzed the carbon composition and PAH isomeric ratios to identify the sources. In this study, EPFR concentrations were measured using electron paramagnetic resonance spectroscopy, with the highest concentration found to be 3.

Introduction: Since November 2023, influenza has ranked first in reported cases of infectious diseases in China, with the outbreak in both northern and southern provinces exceeding the levels observed during the same period in 2022. This poses a serious health risk to the population. Therefore, short to medium-term influenza predictions are beneficial for epidemic assessment and can reduce the disease burden.
