Children Under 6 yrs with Elevated Blood Lead Levels (BLL)

These data are an indicator of children younger that 6 years of age tested in NYC in a given year with blood lead levels of 5 mcg/dL or greater.

About the Data

All NYC children are required to be tested for lead poisoning at around age 1 and age 2, and to be screened for risk of lead poisoning, and tested if at risk, up until age 6. These data are an indicator of children younger that 6 years of age tested in NYC in a given year with blood lead levels of 5 mcg/dL or greater. In 2012, CDC established that a blood lead level of 5 mcg/dL is the reference level for exposure to lead in children. This level is used to identify children who have blood lead levels higher than most children's levels. The reference level is determined by measuring the NHANES blood lead distribution in US children ages 1 to 5 years, and is reviewed every 4 years.

本数据集为纽约市某一年内接受检测且年龄低于6岁的儿童血液铅含量（≥5 mcg/dL）的指标。关于数据集的说明：所有纽约市儿童在约1岁和2岁时均需接受铅中毒检测，并需进行铅中毒风险筛查，若存在风险则需进行检测，直至6岁。这些数据反映了纽约市某一年内接受检测且年龄低于6岁的儿童血液铅含量达到或超过5 mcg/dL的情况。2012年，美国疾病控制与预防中心（CDC）将5 mcg/dL的血液铅含量设定为儿童接触铅的参考水平。此水平用于识别血液铅含量高于大多数儿童的儿童。参考水平通过测量美国国家健康与营养调查（NHANES）1至5岁儿童的血液铅分布确定，并每4年进行一次审查。
