“…It is important to note that not all air pollution causes harm to humans and living things, but only when the quality of the atmospheric environment is degraded to a certain extent does it cause damage to both humans and ecological elements. [4][5][6][7] while the atmosphere has the ability to repair itself, the chemical composition or quantity of air pollutants can prevent it from doing so. If the types of air pollution are subdivided, they can be broadly divided into indoor air pollution and outdoor air pollution.…”

In the process of urbanisation, the lack of attention to environmental issues has led to air pollution becoming more and more serious, with more and more cities experiencing haze and even extreme weather phenomena, posing a huge threat to people's health. Although more and more countries are paying attention to the problem of urban air pollution, they are still not receiving good results. This paper analyses the causes of urban air pollution from the perspective of industrial structure, urbanisation and other aspects, and proposes some measures to solve the problem.

“…Indoor pollution is also an exposure event due to the fuels used for cooking. A study carried out in Colombia regarding the exposure to PM2.5 and black carbon of people with disabilities living in rural areas show that people with disabilities who spend most of the time at home can develop respiratory conditions or worsen current diseases such as hypertension or chronic obstructive pulmonary disease [68]. Traffic is another source of emission of carbonaceous particles, such as BC, and it has been associated, in addition to coronary risks, to deterioration in cognitive abilities [69].…”

The carbonaceous particles represent a significant fraction in the particulate matter (PM) and are considered an environmental hazard due to their effects on climate and health. The main goal in this research is to identify and analyze the scope that have been achieved so far on the characterization and measurement of the carbonaceous fraction present in PM, a great contribution to global pollution and thus to the deterioration of public health. The ProKnow-C methodology was used to build a bibliographic portfolio and perform a bibliometric and systemic analysis of the information found in the chosen databases. The contribution of these carbonaceous compounds to PM is very significant, reaching values up to 50%. The most used methods for the determination of organic and elemental carbon are thermo-optical reflectance and transmittance. Positive Factorization models are used worldwide to determine potential sources of particulate matter emissions. Even though various studies have been developed to understand these carbonaceous substances, there are several limitations in the measurements and limited knowledge on the subject. The positive outcomes and future possibilities were analyzed as well.

“…(2017) measured the fume exposure during a typical Chinese domestic cooking process, reporting the PM 2.5 mass concentration ranging from 0.02 to 6.25μm in the breathing zone was 10.97 ± 9.53 mg/m 3 under normal ventilation situation, and insufficient exhaust of hood resulted in higher exposure level reaching 32.26 ± 31.18 mg/m 3 . In addition, the vulnerable population group (particularly for infants, the very young children, the elders and the chronically ill) have a potential access to the pollutant ( Zhang and Zhao, 2007 ; Shimada and Matsuoka, 2011 ; Chowdhury et al., 2012 ; Abdullahi et al., 2013 ; Li et al., 2017a ; Wang et al., 2017 ; Martinez Vallejo et al., 2021 ). Cooking was investigated in terms of source emission and personal exposure.…”
