We examined respiratory health effects of long-term exposure to ambient air pollution in 7,621 schoolchildren residing in eight districts of four Chinese cities. The four cities exhibited wide between-city and within-city gradients in ambient levels of four size fractions of particulate matter [[less than or equal to] 2.5 pm in aerodynamic diameter (P[M.sub.2.5]), between 2.5 and 10 pm (P[M.sub.10-2.5]), [less than or equal to] 10 [micro]m (P[M.sub.10]), and total suspended particu...
