The fine particulate matter (PM2.5) problem has attracted much scientific and public attention, due to its effects on visibility, human health, and global climate. There are three factors that have important effect on PM2.5 mass concentration: domestic pollutant emission sources, external sources outside of the country, and the meteorological conditions. Nagasaki is a coastal prefecture located...

Although the incidence of bacillary dysentery in China has been declining progressively, a considerable disease burden still exists. Few studies have analyzed bacillary dysentery across China and knowledge gaps still exist in the aspects of geographic distribution and ecological drivers, seasonality and its association with meteorological factors, urban-rural disparity, prevalence and distribut...

The spores have formed by fungi and these spores have developed characteristics that enable them to cope with the stresses of survival and disintegration. In the distribution of fungus spores in the atmosphere, it is important in the meteorological factors as well as the features of the fungus. The meteorological factors that play a role in the distribution of fungus spores are temperature, hum...

Background : Hand, foot, and mouth disease (HFMD) is a contagious viral illness that commonly affects infants and children. This infection is an emerging infectious disease in Rizhao in recent years. The present study examined the short-term effects of meteorological factors on adolescent HFMD in Rizhao. Design : A generalized additive Poisson model was applied to estimate the effects of meteor...

BACKGROUND Pneumonia is common in children and mostly caused by many pathogens. The aim of this study was to investigate whether the incidence of pediatric mycoplasma pneumoniae (MP) pneumonia and respiratory syncytial virus (RSV) pneumonia was associated with meteorological factors in Hangzhou, China. METHODS A total of 36500 pneumonia patients were recruited to participate in the study. Nas...

The formation and break-up of ice on the Great Lakes as observed by regular ice reconnaissance flights conducted by the Meteorological Service of Canada is discussed in terms of the meteorological parameters involved. Ice cover on the individual lakes over the past four years is correlated with the winter temperature regime and an index of the heat stored in each lake using the concept of cumul...

Gaseous and size-segregated particulate PBDEs (specifically BDE-47, -99, -183, -207, and -209) in the air were measured in urban Guangzhou at 100 and 150 m above the ground in daytime and at night in August and December 2010, to assess dry deposition of these contaminants accurately with regards to influences of meteorological factors but without confounding surface effects. Particulate PBDEs w...
