“…More than 70 types of metal elements exist in APM [53][54][55][56]. Aluminum, Si, Ti, Ca, Mn, Fe, and other crustal elements mainly originate from natural sources and exist as coarse particles, which are related to geological and surface conditions, whereas pollutants such as Pb, As, Cr, Ni, Cu, and Cd are mainly derived from anthropogenic sources and are related to human activities, such as industrial production and fuel combustion [56][57][58]. Zou et al [59] analyzed air heavy metal pollution in 53 cities in 29 provinces and found that As, Cr, Cd, Ni, Mn, Pb and other heavy metals in China's atmosphere mainly originate from fossil fuel combustion, metal smelting, and traffic exhaust emissions.…”

Haze is the phenomenon of visibility degradation caused by extinction effects related to the physicochemical properties of atmospheric particulate matter (APM). Atmosphere heterogeneous reactions can alter the physicochemical properties of APM. Therefore, it is important to understand the atmospheric heterogeneous reactions of APM in order to reveal the cause of haze. Herein, the current situation, developmental trend, source, and composition of APM pollution in China are reviewed. Additionally, we introduce the reaction characteristics and key chemical processes of common inorganic, organic, and mixed pollutant gases on the surface of mineral particles. The effects of mineral particulate matter on aggregation, regulation, and catalysis in the formation of atmospheric aerosols and the synergistic reaction mechanism of SO2, NO2, O3, and VOCs on the surfaces of different mineral particles are summarized. The problems existing in the current research on heterogeneous reactions on the surfaces of mineral particles are also evaluated. This paper aims to gain a deep understanding of the mechanism of mineral particulate matter promoting the formation of secondary aerosols and attempts to provide theoretical support for effective haze control.

“…Fine particulate matters have small diameters and large surface areas and may be capable of carrying several toxic substances through diffusion and damaging various parts of the body through air exchange in the lungs. In the present scenario there is no clean or healthy air to breathe for human beings (Rajput et al 2022). Particulate matter and their constituents are the most important compounds present in the air which cause air pollution and adverse health effects for both humans and animals (Yousuf et al 2022).…”

The present study evaluated the concentration, seasonal variations, source identification and health risk through inhalation of heavy metals (V, Cr, Mn, Fe, Ni, Cu, Zn, As, Cd, Si and Pb) in fine particulate matter. Samples of PM2.5 were collected from an urban site in Agra (27°10′N, 78°05′E), India during January 2018 to January 2019. A total of 48 samples of PM2.5 were collected using Fine Particulate Sampler (Envirotech APM 550) set at a flow of 16.6 L min− 1 on 47 mm quartz fiber filters (Pallflex, Tissuquartz) for 24 h. Heavy metals were determined by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) after acid digestion. The average PM2.5 mass concentration was 107 ± 57.85 µg m− 3 which has been compared with NAAQS and WHO limit was found to be higher. Seasonal variation of PM2.5 showed: winter > post-monsoon > summer > monsoon. The average concentration of heavy metals lied within the range of 4.92 to 505.38 ng m− 3. Among heavy metals, the high concentration belonged to Si (505.38 ng m− 3) and Fe (281.23 ng m− 3). The highest metal concentration occurred in the winter season followed by post-monsoon, summer and monsoon seasons. The enrichment factor was used to estimate the main sources of the metals in PM2.5. Two factors were identified using Principal Component Analysis (PCA) at the urban site including resuspended road dust, vehicular activities, solid waste incineration, industrial emission and construction activities. To assess the health risks through inhalation exposure pathway hazard quotient (HQ), hazard index (HI) and carcinogenic risk (CR) were estimated. The carcinogenic risks of Pb (for both children and adults) Cd (for children) were lower than the precautionary criterion (1×10− 6), while Cd for children and As, Cr and Ni for both children and adults were higher than 1×10− 6. The non-carcinogenic risks of As, Cd, Cr, Mn and V for both children and adults were lower than the safe level of 1, whereas Ni for both children and adults were higher than the safe level of 1. The HI values of all heavy metals for both children and adults were higher than the safe level of 1 indicating a non-carcinogenic adverse health effect. The results of the present study impart information for the behaviour and risk mitigation of heavy metals.
