SHANGHAI has seen a slight drop in PM2.5 pollutants since the introduction of tougher environmental legislation this year, officials said yesterday.
However, levels of PM2.5 — tiny particles that are especially harmful as they can get deep into the respiratory system — are still many times global safety levels.
The average PM2.5 density was 52 micrograms per cubic meter between January and August, a 1.9 percent decrease on the same period last year, said the Shanghai Environmental Protection Bureau.
