Pollution levels at schools alarmingly high,finds study

The study monitored air pollution — Respirable Suspended Particulate Matter (fine particles less 2.5 microns in size that trigger asthma),sulphur dioxide and nitrogen oxide — in six schools across Delhi. The study shows RSPM levels were exceedingly high throughout the year,while other pollutants had wavering values. The study covered schools in Saket,Pusa Road,Shalimar Bagh,Chanakyapuri and Noida.

The safe standard is 100 milligram per cubic metre and RSPM counts were dangerously high in all locations. Between October and November 2002,the RSPM levels were above 500 in Saket and Shalimar Bagh. In February 2003,RSPM levels again exceeded safe limits,with the highest being recorded in Saket at 285 milligram per cubic metre. In May the same year RSPM quantities shot up further,registering at 429 milligram per cubic metre in Saket,and 346 milligram per cubic metre in Pusa Road.

During the monsoon,in July and August 2003,RSPM levels came down,exceeding limits only at Pusa Road (152) and Saket (262).

Nitrogen Oxide levels,caused by vehicular pollution were steadily high at Pusa Road.

To counter such high pollution levels,experts at TERI suggest improved parking,and pick-up and drop-off zones for children so as to reduce pollutants associated with automobile exhaust and tail pipe emissions. Dense tree plantation along roads is another way to minimise the transfer of dust and noise,while a hardy grass cover will help reduce dust within school premises.
