Justification: Rising air pollution is an ever-growing threat to many human diseases. Poor air quality has been directly correlated with respiratory allergies with a disproportionate affection among the pediatric age group. A clear understanding of common air pollutants and their potential contribution in allergic rhinitis and asthma is lacking.
Objective: To formulate a consensus statement for appropriate understanding among pediatricians and general practitioners about the effects of air pollution on respiratory allergies and their prevention.
Process: A group of experts (Pediatric pulmonologists and allergy specialists) from across India were appointed by the Indian Academy of Pediatrics (IAP) to formulate a consensus statement on 'Allergy and Air pollution'. A virtual meeting was conducted on 6th April 2020 to discuss in detail regarding various issues related to the subject and a writing committee was formed with broad consensus. After extensive literature review and multiple virtual sessions, the current document was prepared and circulated via email to the representatives from central IAP and IAP environment chapter. All the experts approved the consensus with minor modifications after a detailed discussion on 29th September 2020 on a virtual platform.
Recommendations: Air pollution is the emerging contributor to respiratory allergies due to various mechanisms including oxidative stress and compromised mucociliary clearance. Children are more vulnerable to both outdoor and indoor pollution, due to their unique physiological characteristics. Knowledge about pollutant particle size and air quality index will help in demarcating level and extent of airway involvement. Relevant environmental history in difficult allergic rhinitis and asthma cases, along with conventional pharmacological measures, is warranted. Multipronged approach, targeted at community, physician and individual levels, needs to be emphasized to improve air quality and reduce economic and psychological burden of respiratory allergies.

Adding to the Woes: Heterogeneous Effects of Air Pollution on Pandemic Patients.

While the direct health impacts of air pollution are widely discussed, its indirect effects, particularly during pandemics, are less explored. Utilizing detailed individual-level data from all designated hospitals in Wuhan during the initial COVID-19 outbreak, we examine the impact of air pollution exposure on treatment costs and health outcomes for COVID-19 patients. Our findings reveal that patients exposed more intensively to air pollution, identified by their residence in downwind areas of high-polluting enterprises, not only had worsened health outcomes but also consumed more medical resources.

Granite sludge dust (GSD), a significant byproduct of granite processing globally, poses severe environmental and public health challenges, with India alone generating 200 million tons annually. The conventional use of GSD in soil stabilization and construction materials is limited to 20-30%, underscoring the urgent need for sustainable repurposing solutions within the circular economy catering to broader bulk utilization. Unlike traditional techniques, repurposing granite dust using microbially induced calcite precipitation (MICP) offers a sustainable low-impact and eco-friendly ground improvement solution.

The Gulf States are home to industries emitting styrene, benzene, toluene, ethylbenzene, and xylenes (SBTEX). Presently, adverse health effects of ambient SBTEX exposure in highly polluted regions, such as the Gulf States, must be evaluated. Epidemiologists, however, are limited by inadequate estimates of ambient SBTEX.

Background: Chronic respiratory diseases are important causes of disability and mortality globally. Their incidence may be higher in remote locations where healthcare is limited and risk factors, such as smoking and indoor air pollution, are more prevalent. E-health could overcome some healthcare access obstacles in remote locations, but its utilisation has been limited.

Particulate air pollutants, a major air pollution component, are detrimental to human health and a significant risk to wildlife and ecosystems globally. Here we report the effects of particulate pollutant black carbon on the beneficial gut microbiome of important global insect pollinator, the buff-tailed bumblebee (Bombus terrestris). Our data shows that exposure to black carbon particulates alters biofilm structure, gene expression and initial adhesion of beneficial bee gut coloniser, Snodgrassella alvi.
