“…Although in many of the analysed studies, urinary levels of Cr and Ni were assessed, only two studies focused on hazardous waste incineration reported HBM data for Cr, Ni and PAHs. However, the co-occurrence of these substances has been recognized in many other industrial activities [66], e.g., in electromechanical repair and car painting centres, sewing work rooms, chemical analysis laboratories [67], coke oven plants, aluminium production, iron and steel founding and welding industries, among others [18][19][20], showing the paucity of data allowing the assessment of the risks related to those mixtures exposure.…”

Hexavalent chromium (Cr(VI)), nickel (Ni) and polycyclic aromatic hydrocarbons (PAHs) are genotoxic co-occurring lung carcinogens whose occupational health risk is still understudied. This study, conducted within the European Human Biomonitoring Initiative (HBM4EU), aimed at performing a mixtures risk assessment (MRA) based on published human biomonitoring (HBM) data from Cr(VI), Ni and/or PAHs occupational co-exposure in Europe. After data extraction, Risk Quotient (RQ) and Sum of Risk Quotients (SRQ) were calculated for binary and ternary mixtures to characterise the risk. Most selected articles measured urinary levels of Cr and Ni and a SRQ > 1 was obtained for co-exposure levels in welding activities, showing that there is concern regarding co-exposure to these substances. Similarly, co-exposure to mixtures of Cr(VI), Ni and PAHs in waste incineration settings resulted in SRQ > 1. In some studies, a low risk was estimated based on the single substances’ exposure level (RQ < 1), but the mixture was considered of concern (SRQ > 1), highlighting the relevance of considering exposure to the mixture rather than to its single components. Overall, this study points out the need of using a MRA based on HBM data as a more realistic approach to assess and manage the risk at the workplace, in order to protect workers’ health.

“…Vehicles emissions, combustion processes and industrial activities are recognizing as the main source of atmospheric contamination in urban centers. Particulate material, nitrogen and sulfur oxides, heavy metals and different volatile organic compounds (VOCs), among which are the so-called BTEX (benzene, toluene, ethylbenzene and xylenes), have been set as priority pollutants in atmospheric contamination studies [2,3]. The ways these pollutants can affect human health are varied: benzene influences nervous system and it is a carcinogenic-related with leukemia [4].…”

In this work, chemometric and spatial interpolation methods were used to characterize non-conventional pollutants in the atmosphere of the city of Santiago de Cali (Colombia), The contaminants were monitored using passive diffusion samplers during two (2) periods (January to February and March to April) in two consecutive years before the pandemic (2020). None of the cases exceeded the concentration limits established by the National Air Quality Standard. The Cluster analysis allowed evidencing the existence of groups, which correspond to low, medium and high influence sites of the pollutants. The Principal Components Analysis (PCA) led to gathered all the variables in two constituents: the first one (PC1) could be related as an indicator of pollutant mobile sources due to the similar contribution of pollutants, while the second one (PC2) as an indicator for punctual emissions of toluene, as it was the one that contributed the most. The performance of the spatial analysis drove to identify the downtown and north of the city as areas of high-influence of PC1, at the same time, a substantial decrease in its effects to the periphery, particularly towards the south. On the other hand, with the Inverse Distance Weighting (IDW) it was possible to observe the hot-spots of both PCs, particularly real estate construction areas and the downtown industrial sector of the city. Finally, it was found a cancer risk in downtown and north-eastern areas of the city, related to the exposure to benzene and ethylbenzene; observation that coincide in the area of incidence of PC1.

The substances associated with PM2.5‐induced inflammatory response were investigated using an elimination method. PM2.5 were heated at temperatures of 120, 250, and 360°C. The results demonstrated microbial substances such as LPS and b‐glucan, and chemicals including BaP, 1,2‐NQ, and 9,10‐PQ were reduced drastically in PM2.5 heated at 120°C. On the other hand, DBA, 7,12‐BAQ, and BaP‐1,6‐Q were not noticeably reduced. Most of these substances had disappeared in PM2.5 heated at 250°C and 360°C. Metals (eg, Fe, Cu, Cr, Ni) in PM2.5 exhibited a slight thermo‐dependent increase. RAW264.7 macrophages with or without NAC were exposed to unheated PM2.5, oxidative stress‐related and unrelated inflammatory responses were induced. PM2.5‐induced lung inflammation in mice is caused mainly by thermo‐sensitive substances (LPS, b‐glucan, BaP, 1,2‐NQ, 9,10‐PQ, etc.). Also, a slight involvement of thermo‐resistant substances (DBA, 7,12‐BAQ, BaP‐1,6‐Q, etc.) and transition metals was observed. The thermal decomposition method could assist to evaluate the PM2.5‐induded lung inflammation.
