The breast milk lead levels among Chinese population.

Breast milk is a potential source of infant and young children lead exposure, but national-level data on breast milk lead (BML) is unknown in China. To fill up this gap, we conducted a review by analyzing the articles enrolled through searching Wanfang MedOnline, CNKI, SinoMed, Pubmed, and Embase databases and relevant articles from 2000 through 2017. After screening and assessing process, 17 articles were included.

Surveillance of childhood blood lead levels in 11 cities of China.

Background: Exposure to lead can be deleterious to children's health. Surveillance for blood lead levels (BLLs) is reported every year in the USA and some other countries. However, such reports are lacking in China which has the world's largest population of children.

Blood lead levels among children aged 0 to 6 years in 16 cities of China, 2004-2008.

Background: The adverse health effects of lead for children under 6 years are well known. Studies to assess the lead exposure among children in China are small in sample size and lack of national representative data. The aim of this study therefore was to describe blood lead levels and identify risk factors for lead exposure among children aged 0 to 6 years living in 16 cities in China.

[Blood lead status and influencing factors among preschool children in urban areas of China].

Objective: To investigate the blood lead status and influencing factors among preschool children in the sampling city.

Method: Stratified-clustered-random sampling was used. Standardized questionnaire and peripheral blood samples were obtained from 69 968 children aged 0-6 years in fixed kindergartens and communities of Yinchuan, Xi'an, Chengdu, Wuhan, Hefei, Beijing, Harbin, Zhengzhou, Huhhot, Shijiazhuang, Haikou, Dalian, Qingdao, Guangzhou, Nanning and Changsha from 2004 to 2008, respectively.

Surveillance of childhood blood lead levels in 14 cities of China in 2004-2006.

Objective: To investigate the blood lead level in children aged 0-6 years in urban areas of China.

Methods: Fourteen cities were selected as sites under surveillance. A total of 44 045 peripheral blood specimens were collected from 2004 to 2006, during which 15 727, 14 737, and 13 584 specimens were tested in 2004, 2005, and 2006, respectively.

[Study on blood lead level and related risk factors among children aged 0-6 years in 15 cities in China].

Objective: To observe blood lead level and related risk factors among children aged 0-6 years old living in cities in China and to provide data for policy development to the prevention on environmental lead pollution.

Methods: A stratified-clustered-random sampling method was used. 17 141 peripheral blood samples of 0-6 years old children from 15 cities in China were tested.
