“…As an example, concerning UFPs, many studies have found that an increase in temperature was associated with an increase of their concentration (Minet et al, 2018a;Pattinson et al, 2017), while others indicate a decrease (Farrell, Weichenthal, Goldberg, & Hatzopoulou, 2015;Hatzopoulou et al, 2013b). In the same vein, Qiu et al (2019) found a negative relationship between humidity and UFP concentration, whereas Farrell et al (2015) and Minet et al (2018b) found a positive relationship.…”

“…Contrary to this, a second study group adopts a more comprehensive approach to cyclists' exposure and attaches a particular importance to the identification of factors contributing to significant decrease or increase of levels of exposure (Apparicio et al, 2016;Brand et al, 2019;Gelb & Apparicio, 2019, 2020Krecl et al, 2019;Pattinson et al, 2017;Qiu, Wang, Zheng, & Lv, 2019).…”

Cyclists constitute a population particularly exposed to atmospheric and noise pollution in urban environments; at the same time, they contribute to its reduction. For about ten years now, more and more studies have been completed to assess cyclists' exposure, comparing this mode of transportation with others, quantifying its impacts in term of individual and collective health, understanding cyclists' perceptions regarding their exposure, etc. Though some literature reviews have examined some of these specific issues, none have yet proposed a general overview of this field of study. Therefore, this mapping literature review fills this gap by jointly analysing 205 articles and identifying elements of consensus and disagreement, as well as existing gaps. Among others, our results indicate that the cities in the South and exposure to noise are under-studied and that cyclists' ventilation is still too rarely accounted for, regardless of the type of studies. Modelling studies regarding exposure are too heterogeneous methodologically to allow a generalisation of their results. Conversely, intermodal comparison studies clearly indicate overexposure for cyclists compared to other modes. Also, health studies conclude that, either individually or collectively, the benefits of cycling surpass the costs of exposure to atmospheric pollution. The knowledge produced by this research trend remains difficult to exploit by urban planners, but the recent work done seems to offer more practical perspectives to professionals.

“…Several other recent studies reported on the effect of route on TRAP exposure only, with most focused on cyclists. These studies consistently found routes with less vehicle traffic were associated with lower BC concentrations, with less consistent evidence of reductions in UFP or PM 2.5 [104][105][106][107][108][109][110]. A study in Fort Collins, Colorado, a city with relatively low levels of air pollution, also found that by selecting an alternative route drivers significantly reduced cumulative exposures to BC and carbon monoxide by 15%, but PM 2.5 exposures were unchanged [110].…”

Purpose of Review We reviewed recent peer-reviewed literature on three categories of individual- and household-level interventions against air pollution: air purifiers, facemasks, and behavior change. Recent Findings High-efficiency particulate air/arresting (HEPA) filter air purifier use over days to weeks can substantially reduce fine particulate matter (PM2.5) concentrations indoors and improve subclinical cardiopulmonary health. Modeling studies suggest that the population-level benefits of HEPA filter air purification would often exceed costs. Well-fitting N95 and equivalent respirators can reduce PM2.5 exposure, with several randomized crossover studies also reporting improvements in subclinical cardiovascular health. The health benefits of other types of face coverings have not been tested and their effectiveness in reducing exposure is highly variable, depends largely on fit, and is unrelated to cost. Behavior modifications may reduce exposure, but there has been little research on health impacts. Summary There is now substantial evidence that HEPA filter air purifiers reduce indoor PM2.5 concentrations and improve subclinical health indicators. As a result, their use is being recommended by a growing number of government and public health organizations. Several studies have also reported subclinical cardiovascular health benefits from well-fitting respirators, while evidence of health benefits from other types of facemasks and behavior changes remains very limited. In situations when emissions cannot be controlled at the source, such as during forest fires, individual- or household-level interventions may be the primary option. In most cases, however, such interventions should be supplemental to emission reduction efforts that benefit entire communities.

“…It is well-known that exposure to air and noise pollution contributes to detrimental effects on respiratory and cardiovascular systems [1][2][3]. These exposures are indeed a major contributor to increased length of in-hospital stay, morbidity, and mortality associated with chronic diseases [4][5][6]. Although the causes are multifactorial, one of the pathophysiological mechanisms entails acute changes in cardiovascular autonomous modulation [7].…”

Exposure to traffic-related air pollution and noise exposure contributes to detrimental effects on cardiac function, but the underlying short-term effects related to their simultaneous personal exposure remain uncertain. The aim is to assess the impact of total inhaled dose of particulate matter and total noise exposure on the variations of electrocardiogram (ECG) parameters between pre-cycling and post-cycling periods. Mid-June 2019, we collected four participants’ personal exposure data related to traffic-related noise and particulate matter (PM2.5 and PM10) as well as ECG parameters. Several Bayesian linear models were built to examine a potential association between air pollutants and noise exposure and ECG parameters: heart rate (HR), standard deviation of the normal-to-normal intervals (SDNN), percentage of successive RR intervals that differ by more than 50 ms (pNN50), root mean square of successive RR interval differences (rMSSD), low-frequency power (LF), high-frequency power (HF), and ratio of low- to high-frequency power (LF/HF). We analyzed in total 255 5-min segments of RR intervals. We observed that per 1 µg increase in cumulative inhaled dose of PM2.5 was associated with 0.48 (95% CI: 0.22; 15.61) increase in variation of the heart rate, while one percent of total noise dose was associated with 0.49 (95% CI: 0.17; 0.83) increase in variation of heart rate between corresponding periods. Personal noise exposure was no longer significant once the PM2.5 was introduced in the whole model, whilst coefficients of the latter that were significant previously remained unchanged. Short-term exposure to traffic-related air and noise pollution did not, however, have an impact on heart rate variability.
