All rapid responses
Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.
From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.
The word limit for letters selected from posted responses remains 300 words.
To the editor
We have read with a great interest the analysis provided by Mr. Robin Russell-Jones.[1] As numerous scientific articles focus on effects of pollution on population's health, he promotes drastic actions aiming to decrease pollutants emission by transport vehicles, in particular diesel vehicles.[2] Some of those actions are targeted at limiting access to specific zones, such as urban or suburban ones. We completely agree with his conclusions. Nevertheless, most of the studies have focused on specific pollutant or disease, whereas pollution impact is, without any doubt, much larger. In addition, achieving all proposed recommendations, although essential, might take a long, long time. In the meantime, focusing only on pollutants concentration cutoffs (rarely respected, whatever the country) could be insufficient to forecast the go for exceptional corrective actions as speed or circulation limiting.
Our Center for the Reception and Regulation of Medical Calls (CRRMC) is situated in the northeastern part of Paris, in the 93rd department, a 236 km2 area inhabited by approximatively 1.6 million people. The aim of our CRRMC (SAMU 93) is to manage all medical calls, whatever their reason or level of severity, in the related area. The latter is characterized by a dense network of streets, roads and speedways, as many sources of pollutants from exhaust gases. Moreover, our geographical situation exposes us to Parisian emissions carried by the prevailing winds from west to east. Therefore, we wanted to determine whether indices able to forecast the need for exceptional actions as we previously described could be found.[3] We analyzed the relationship between air pollution levels (recorded and classified according to five levels by local authorities) and the number of calls. 639,576 calls were managed in a period of 1,134 consecutive days, from December 30, 2013 to February 5, 2017. The results showed that the number of calls was strongly correlated with air pollution levels (R2=0.9). The median number of calls was 564 (507-643) per day. It increased from 502 (494–621) to 650 (540–704) respectively during the days with the best (N=7) and the worst air quality (N=60).
Such a global analysis based on a large population, regardless of the pathology or its severity, shows a strong relationship between air pollution levels and the need for health care, including primary care. Thus, global request for healthcare can be a useful tool to evaluate or even forecast both, pollution as well as corrective action impacts on population's health.

Re: Air pollution in the UK: better ways to solve the problem
Let’s face it you got rid of the coal fire made every one pay for more gas when we were told plenty out at sea you don’t say any thing about all the burn off from the drilling rigs you don’t say any thing about airplanes in the sky just go on again about the old fav motor vehicles other country’s couldn’t give a toss so why should little old Brit dos our little air clean zone stay with us as we go round and round or are we cleaning the whole globe that’s what I think councils every were are building houses left right and centre putting more traffickers in our city’s. and you go on and on the towers you put up free electricity yet we pay more for it will them towers ever repay what they cost No what good are they doing nothing half never go round but you can still give a million a year to empower and other providers for 35 years our money I can spend other people’s money too B harper
