“…It has been reported that long-term occupational exposure is related to a slight increase in both systolic and diastolic blood pressure 25) . As in similar studies evaluating the effect of lead exposure on blood pressure 26) , our study showed that there was no significant relationship between blood lead levels and systolic and/or diastolic blood pressure.…”

“…Systolic and diastolic blood pressure, evaluated in eight studies (12,13,(28)(29)(30)(31)(32)(33), and heart rate, in two studies (31,34), show no statistically significant differences in the exposed compared to controls. The studies were heterogeneous between them.…”

“…Reviewed studies are heterogeneous, as to the outcomes. Among 16 studies of our meta-analysis, only five focused on the association between urban pollution and effects on the cardiovascular system (12,13,29,32,47). One of the remaining studies (37) (analyzing the incidence of coronary heart disease in professional drivers), identified among the potential risk factors both urban pollution and specific work factors.…”

SummaryBackground: many studies showed a connection between exposition to high levels of urban pollution (especially to particulate and traffic noise) and the onset of even deadly cardiovascular diseases. Design: meta-analysis of case-control design. Objectives: the aim of this study is to estimate the association between cardiovascular effects and occupational exposition to atmospheric pollution in urban environment. There has not been any kind of language or typological restriction. Criteria of Elegibility: the research on cardiovascular effects includes control cases of workers exposed to urban pollution, compared with non-exposed subjects. Participants and Interventions: the selected studies present outdoor workers exposed to urban pollution (drivers and petrol pump attendants) and a control group of indoor workers (managers, university students and other selected subjects). Study Appraisal and Synthesis Methods: the evidences (independently token from two different authors) have been grouped in two classes, the first one formed by continuous variables (systolic blood pressure, diastolic blood pressure, heart rate, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) and the second one by discontinuous variables (electrocardiographic abnormalities prevalence, hypertension prevalence, hypercholesterolemia prevalence). The studies related to both classes and presenting more than one variable for each class have been included and used, in order to elaborate the results. We calculated heterogeneity in each variable (ES calculation for continuous variables and OR calculation for discontinuous variables). Results: on 378 publications, we have selected and included 16 articles. The variables show statistically irrelevant differences between exposed group and control group, except regarding the triglycerides. Limitations: The controlled studies are limited and characterized by a non-homogeneous evaluation of both expositional times of workers to urban pollution and of professional expositional values. Conclusions: considering the heterogeneity and the lack of studies, it is impossible at the moment to document effects on the cardiovascular system in workers exposed to urban pollution. The results of this meta-analysis only suggest the association of urban pollution with alteration of triglycerides blood levels (referring to just three studies). As reported in scientific literature on this subject, it is necessary to conduct a future professional investigation on this subject with more qualified and homogeneous studies.

“…Testing conducted in 2014 in the smelter town of La Oroya found BLLs in 58% of 335 children >10 μg/dL (Red Salud, 2014). Other studies in Peru have found BLLs associated with traffic levels in police officers (Mormontoy et al, 2006) and mineral ore storage in Callao (Hernandez Avila, 1999;Naeher et al, 2003;Vega-Dienstmaier et al, 2006).…”

Does Involving Parents in Soil Sampling Identify Causes of Child Exposure to Lead? A Case Study of Community Engagement in Mining‐Impacted Towns in Peru

et al. 2019

Over a million people in Peru may be exposed to lead (Pb) due to past or present mining‐related activities; however, neither soil Pb nor blood Pb are routinely monitored throughout the country. Because little is known about Pb contamination in smaller mining‐impacted towns, soil Pb was mapped in four such towns with a portable X‐ray fluorescence analyzer in 2015. The roadside mapping delineated hotspots of highly contaminated soil (1,000–6,000 mg/kg Pb) in two of the towns. The local health department, provided with a LeadCare II analyzer, then measured blood‐Pb levels >5 in 65% and >10 μg/dL in 15% of children (n = 200) up to 6 years of age in these same four communities. There were no clear relations between child blood‐Pb levels and Pb levels in soil samples collected inside (n = 50) or outside the home (n = 50). Increased child blood Pb was associated with decreased level of cleanliness of parent clothing (n = 136) and shoes (n = 138), linking a possible behavioral factor for transferring contaminated soil and dust to children. In order to explore individual exposure and variations in soil Pb, 10 parents of children with blood Pb >10 μg/dL and 10 parents of children with blood Pb <5 μg/dL were invited to collect soil samples in areas where their children play and screen it for Pb using a color‐based field procedure. Importantly, parents identified a new hotspot of Pb contamination that had been missed by the previous portable X‐ray fluorescence soil mapping. The findings highlight the feasibility and value of involving families impacted by environmental contamination to identify and reduce environmental health risk.
