Tinfoil manufacturing and electronic waste (e-waste) recycling remain rudimentary processes in Zhejing Province, China, which could account for elevated blood lead levels (BLLs) and health impacts on children. We assessed the potential health risks of lead in tinfoil manufacturing and e-waste recycling areas. 329 children in total aged 11-12 who lived in a(More)
Thyroid diseases(TD) can be induced by either deficient or excessive iodine intake. Universal Salt Iodization(USI) program has been implemented in China since 1995, to prevent iodine deficiency disorders (IDD). To evaluate the current conditions of TD and the role of USI, a multi-stage stratified random sampling scheme was used to perform a cross-sectional(More)
Iodine is an essential nutrient for the synthesis of thyroid hormones that are critical for brain development. Iodine deficiencies were prevalent in China until the introduction of universal salt iodization (USI) in 1995. USI has been considered as the world’s best achievements. This study aims to assess children’s iodine nutrition and goiter status in(More)
The aim of the present study was to explore the influencing factors of urinary iodine concentration (UIC) and the relationship between iodised salt concentration and UIC in order to give suggestions for the surveillance of iodine nutrition status. For this purpose, a multi-stage cluster sampling technique was employed in the present cross-sectional study.(More)
OBJECTIVE To assess the level of dietary iodine intake and its contribution in Zhejiang. METHODS A total of 9798 subjects were recruited in this survey with multi-stage stratified cluster random sampling method in April, 2010, the 24-hours dietary recall method and the "food composition table" were used to obtain the dietary iodine intake, and edible salt(More)
BACKGROUND Universal salt iodization (USI) was introduced in China in 1995, but whether the iodine status is optimal is questionable. This study was conducted to assess the iodine nutrition among Zhejiang population in coastal regions in China. METHODS A cross-sectional survey for iodine nutritional status was conducted with general population (n=10,350),(More)
OBJECTIVES To evaluate the difference of iodine nutritional status between rural and urban residents under the universal salt iodisation policy. SETTING A multistage cluster sampling technique was employed in the present cross-sectional study. In total, 3300 rural and 3300 urban households were selected where the investigation was conducted.

OBJECTIVE To understand the current status of iodine nutrition among the community residents to compare the level of iodine nutrition in different areas and groups of populations in Zhejiang province. METHODS Stratified cluster sampling method was adopted and residents from twenty-two communities in Zhejiang province were selected. A cross-sectional(More)
OBJECTIVE To study the internal and external dioxins exposure level of children living near the waste incineration power plant. METHODS Peripheral blood of children (90 in S, 60 in L), soils, crucians, chicken eggs were sampled in town S (1 km away from a big waste incineration power plant), as well as in town L (200 km away from S), which is the control.(More)
BACKGROUND Conjunctivitis, one of the most common ocular surface diseases, can be caused by many factors. OBJECTIVES The objective of this study was to investigate the potential association between conjunctivitis and air pollutants. MATERIALS AND METHODS Data of 9737 outpatient visits for conjunctivitis from July 1, 2014 to June 30, 2016 were obtained(More)
