Increasing trend of primary NO(2) exhaust emission fraction in Hong Kong.
Environ Geochem Health
December 2011
Article Synopsis
- Despite reducing roadside nitrogen oxides (NOx) in Hong Kong, nitrogen dioxide (NO2) levels remain unchanged, possibly due to an increasing percentage of primary NO2 emissions.
- The population is at risk from these traffic-related pollutants, especially in congested areas surrounded by tall buildings.
- An analysis showed that the primary NO2 fraction from vehicle emissions rose from 2% in 1998 to 13% in 2008, highlighting the need for future vehicle emission controls to address primary NO2 specifically, alongside overall NOx reduction.
Time series analysis of Japanese encephalitis and weather in Linyi City, China.
Int J Public Health
April 2012
Objectives: To examine the relationship between meteorological factors and epidemiological pattern of Japanese encephalitis in Linyi City during 1956-2004.
Methods: Autoregressive integrated moving average (ARIMA) models were used to evaluate the relationship between monthly JE incidence and weather factors. Logarithmic transformation was applied to the JE incidence series to assure the normality and homogeneity of variance of the residuals.
