mean lead
3.Results Mean blood lead level was 78.5μg/L among 3~5 years old children in Wuhu. The blood lead level of 8.8% children was lower than 50 μg/L and that of 18.6% children was equal or more than 100 μg/L. The blood lead level of 41.1% children in Shi Cheng kindergarten was equal or more than 100 μg/L.
6.It also shows significant positive correlations between mean tropospheric temperature over the North region(including North China, Northeast China, East Mongolia and Korea Peninsula) with the interdecadal variation of Indian summer monsoon. The declining of the mean troposphere temperature over the North region may lead to the weakening of the Indian summer monsoon intensity via the changing of land-sea thermal contrast.
