Lead-poisoned boys are more aggressive, delinquent
Children's health researchers found that boys with relatively high levels of lead in their bones are more likely to engage in aggressive acts and delinquent behavior than boys with lower bone-lead levels. Follow-up studies also associated high blood-lead levels with antisocial acts. This longitudinal study's initial results, announced in 1996, were confirmed. The study linked both prenatal and postnatal lead exposure to aggression and antisocial behavior.
Women can pass lead to infants via breast milk
Children's health researchers discovered that lead that has accumulated in a woman's bones from earlier exposures can be released during pregnancy and transferred to breast milk during lactation.
NTP issues 1st Report on Carcinogens
The National Toxicology Program released the 1st Report on Carcinogens, which listed 26 chemicals and industrial processes with potentially harmful effects on human health. The Report on Carcinogens is an informational scientific and public health document that identifies and discusses agents that may pose a hazard to human health by virtue of their carcinogenicity. It lists these agents in two categories - "known to be human carcinogens" and "reasonably anticipated to be human carcinogens." Some examples of substances identified as known to be carcinogenic include benzene; asbestos; dioxin, such as 2,3,7,8- Tetrachlorodibenzo-p-dioxin; environmental tobacco smoke; and tobacco smoking. The NTP is currently reviewing additional nominations for possible listing in or removal from the 12th Report on Carcinogens. The NTP has identified additional nominations that it may consider for review as either a new listing in or changing the current listing in the 12th RoC.
Cognitive, behavioral development delayed in children exposed to lead
Children's health researchers demonstrated that exposure to very low levels of lead during early childhood can lead to significant delays in cognitive and behavioral development.
