Since October 19, the PM2.5 levels, which is one of the key pollutants, in Delhi has hovered well above 120 micrograms, while even crossing 200 a couple of times. While the World Health Organization (WHO) guidelines recommend the average PM2.5 levels to be at 15 micrograms per day, reported Healthy Policy Watch. In June 2023, when New York hit PM2.5 levels of 117 micrograms, advisories were issued to shut down schools, for people to remain indoors, and to wear masks. However, there have been no such advisory in Delhi so far. The data on Delhi pollution has been unreliable, several media outlets have reported the discrepancy between the official data and the on ground data. Many videos online have also shown the gap between these data where people are using their private AQI machines to measure the air quality. Furthermore, a video from opposition legislator Saurabh Bharadwaj that showed water being sprinkled around a government-run air monitoring station in the city on Diwali night have also raised questions on whether the data was tampered. Amid all this, while doctors have time and again have asked everyone to stay safe, wear mask, and avoid going out during peak hours, studies too have shown fatal links with worsening air pollution. Now, there is an increased risk for infants too. Dr Anjana Singh, director and head of Obstetrics and Gynaecology at Fortis, Noida, as told to the Indian Express said, "Nowadays each newborn is spending a longer time in the nursery before they can be discharged because they are born with respiratory problems and their lung function needs to be stabilised. Some of them have delayed lung development and congenital asthma later. More and more babies are being born with jaundice."Pollution And Infant HealthThe doctor points out that pollution has a deep impact on fetal development than one may think. "It is the reason why we are seeing many more cases of miscarriage, pre-term births, stillbirths, birth defects, congenital heart disease and neural tube defects (the brain and spine do not develop properly)," the doctor explains. Toxic particles can cross the placenta, the temporary organ that links a baby to the mother through the umbilical cord, and disrupt normal development. They trigger inflammation in the placenta, which creates resistance to blood flow. Over time, the blood vessels become damaged, reducing the amount of blood reaching the fetus.Air pollution can mess with how nutrients reach the baby, which often leads to low birth weight. Research also shows that when a pregnant woman is exposed to polluted air, the risk of stillbirth goes up, especially in the third trimester.High levels of fine particulate matter (PM2.5) are linked to low birth weight and premature birth, both of which can cause other health problems. Tiny sooty particles can move through the mother’s bloodstream to the placenta and affect the baby’s lung development, raising the risk of lifelong breathing issues like asthma.Pollutants such as nitrogen dioxide and PAHs which come from things like burning food, coal, oil or gas can disrupt how organs form. This can increase the chances of conditions like congenital heart defects, neural tube problems or cleft palate. Some studies also suggest that heavy exposure to air pollution during pregnancy may raise the risk of autism spectrum disorder.Air pollution can also push the mother’s blood pressure up, increasing the risk of preeclampsia, which is dangerous for both mom and baby.Microplastics in the air come from synthetic clothes, car tires and broken down plastic waste. They act as endocrine disruptors, meaning they can interfere with hormones during key stages of development. They’ve been linked to gestational diabetes, inflammation and gut microbiome imbalance. Microplastics have even been found in the placenta, umbilical cord and cord blood, showing they can reach the baby and interfere with organ and nervous system development.
