TL;DR: A highly significant association was found between lead exposure and children's IQ and the effect was robust to inclusion or exclusion of the strongest individual studies and to relaxing the age requirements of the meta-analysis.

TL;DR: Evidence is added that dead-on-arrival deaths and deaths outside of hospitals and clinics were disproportionately increased and the age pattern of the relative risk of death was similar, which adds to the evidence that the association is causal.

TL;DR: Univariate analysis and multivariate analysis of variance revealed that the pairs differed on symptom reporting, emotional state, motor functions, cognitive flexibility, and olfactory perception threshold, which is consistent with current knowledge on brain Mn activity.

TL;DR: Air pollution in São Paulo has reached levels high enough to have adverse health effects on the exposed population, and a significant association between mortality due to respiratory diseases and the NOx levels is demonstrated.

TL;DR: The results of the study suggest that among black children from low-income families, asthma may be exacerbated following periods of high ozone pollution.

TL;DR: Despite years of concern about the consequences of leaded paint poisoning, children continue to be poisoned by leaded Paint poisoning because it will cost billions of dollars to abate the hazard, and demand for these dollars has lost out to competing needs.

TL;DR: The association between early lead exposure and later problem behaviors was evaluated prospectively in a cohort of 8-year-old children born during a 12-month period at one hospital and suggested that social and emotional dysfunctions are correlates and may be expressions of increased lead exposure.

TL;DR: Assessment of whether the consumption of fish and shellfish containing a high concentration of organoarsenical compounds was associated with the release of a significant amount of inorganic arsenic (Asi) in vivo found that among the different marine organisms analyzed, the highest proportion of Asi was found in mussels.

TL;DR: During three consecutive winters acute effects of air pollution on respiratory health of more than 1000 children living in four nonindustrial communities in the Netherlands have been investigated, finding a weak negative association between the concentrations of nitrogen dioxide, PM10, aerosol sulfate, aerosols nitrate, nitrous acid, and pulmonary function.

TL;DR: It is suggested that particulate air pollution during photochemically active periods is related to respiratory morbidity in Montreal.

TL;DR: It is demonstrated that translational exposure to a PCB mixture that has little notable effect on the dams, not only delays puberty in the female offspring, but also several months later results in decreased uterine response, impairment of fertility, and irregular cycle patterns.

TL;DR: No major effects on pregnancy outcome were seen but the indicated increase in Down syndrome and childhood leukemia--if not random--could be a result of radioactive exposure.

TL;DR: This study shows that a single plasma cotinine determination gives a good impression of c nicotine levels, and it is dubious if a brief questionnaire about hours of passive smoke exposure in nonsmokers is valid to distinguish ETS-exposed from Ets-unexposed nonsmoker.

TL;DR: The comparative potency procedure suggests that ceiling and STEL values of some solvents may not reliably protect workers from acute nervous depression.

TL;DR: It is suggested that SO2 and NO2 concentrations lower than those given as guidelines in many countries, and lower than previously shown, may increase the incidence of symptoms in some patients with chronic bronchitis or emphysema.

TL;DR: The DMSA effect on plasma cGMP (EDRF) may occur via a scavenging effect on EDRF-inactivating reactive oxygen species because DMSA was shown to act as an antioxidant in vitro.

TL;DR: The results suggest that the prognosis of subjects with Cd-induced renal dysfunction is unfavorable, with the mortality rate increasing even in the early stage of proximal tubular dysfunction.

TL;DR: The finding of proteinuria was predictive of serious health consequences, and data support that causal proteinuria should be considered as a marker for risk of poor health outcomes.

TL;DR: It is concluded that animals are more at risk than their owners of having a high BLC when exposed to the same contaminated environment and can be used to monitor the bioavailability of lead.

TL;DR: The results suggest that exposure to malodorous sulfur compounds may affect the health of children, and long-term exposure to these compounds released from pulp mills is a determinant of eye and respiratory symptoms and headache in children.

TL;DR: The linear theory used to extrapolate the cancer risk of radon exposure from high levels where direct data are available to low levels encountered in homes is tested by comparing lung cancer rates, m, and average radon levels, r, in numerous U.S. states and counties.

TL;DR: A mathematical model of fiber clearance from the rat lung was developed and it was found that the clearance rate did not depend significantly upon fiber size but there was a clear dependence on lung burden.

TL;DR: Mapping of the distribution of mercury in the neocortical layers of the maternal brains revealed that the pyramidal cells contained more visualized mercury than the other neurons in the offspring brains, and mercury was found in both glial cells and neurons both in the cortical areas and in the fiber systems.

TL;DR: The possible negative effect of selenium to produce differences in reported geographical variation in disease could not be substantiated in this study.

TL;DR: The past exposure assessment of drinking water carcinogenicity was done in terms of the drinking water mutagenicity estimated from historical water parameters and compared with the methods used previously in past exposure assessments in studies on drinking water and cancer.

TL;DR: The present approach to the estimation of missing particulate air pollution may increase the level of exposure misclassification, but it does allow for the use of existing network databases in epidemiological studies of daily air pollution health effects even though particulate data is only measured on certain days.

TL;DR: Results suggest that GI lead absorption was enhanced by succimer and that succimer mediated the redistribution of lead from the circulation to other tissues, and that patients be maintained in a lead-safe environment while being treated with succimer.

TL;DR: The relationship between a frequently used wipe dust collection method and a vacuum-based in-line filter method used to collect dust in a national survey of lead in paint and dust in U.S. housing is characterized and the resulting increase in the estimated prevalence of homes with elevated dust lead loadings is discussed.

TL;DR: The in vitro genotoxicity of air particulate material from the 1991 oil fires in the Kuwait desert was studied and no increase in DNA adduct formation was observed in AHH-1 cells treated with particulates isolated from sampling in Kuwait.
