Case studies and evidence-based approaches to addressing urban soil lead contamination

Urban soils in many communities in the United States and internationally have been contaminated by lead (Pb) from past use of lead additives in gasoline, deterioration of exterior paint, emissions from Pb smelters and battery recycling and other industries. Exposure to Pb in soil and related dust is widespread in many inner city areas. Up to 20–40% of urban children in some neighborhoods have blood lead levels (BLLs) equal to or above 5 μg per decilitre, the reference level of health concern by the U.S. Centers for Disease Control. Given the widespread nature of Pb contamination in urban soils it has proven a challenge to reduce exposure. In order to prevent this exposure, an evidence-based approach is required to isolate or remediate the soils and prevent children and adult's ongoing exposure. To date, the majority of community soil Pb remediation efforts have been focused in mining towns or in discrete neighborhoods where Pb smelters have impacted communities. These efforts have usually entailed very expensive dig and dump soil Pb remediation techniques, funded by the point source polluters. Remediating widespread non-point source urban soil contamination using this approach is neither economical nor feasible from a practical standpoint. Despite the need to remediate/isolate urban soils in inner city areas, no deliberate, large scale, cost effective Pb remediation schemes have been implemented to isolate inner city soils impacted from sources other than mines and smelters. However, a city-wide natural experiment of flooding in New Orleans by Hurricane Katrina demonstrated that declines in soil Pb resulted in major BLL reductions. Also a growing body of literature of smaller scale pilot studies and programs does exist regarding low cost efforts to isolate Pb contaminated urban soils. This paper reviews the literature regarding the effectiveness of soil Pb remediation for reducing Pb exposure and BLL in children, and suggests best practices for addressing the epidemics of low-level Pb poisoning occurring in many inner city areas

Quality of life in peri- and post-menopausal Polish women living in Lublin Province - differences between urban and rural dwellers

Introduction and objective: The quality of life in peri- and post-menopausal women constitutes a serious public health problem. The aim of this observational cross-sectional study was to reveal the influence of the permanent domicile on the quality of life of women in peri- and post-menopausal period, and to establish the influence of employment as a full-time agricultural worker on the quality of life in these women. Materials and methods: The research was carried out by means of a survey using the postal questionnaire technique. Three standardized questionnaires: WHOQOL-BREF, Women’s Health Questionnaire (WHQ) and SF-36 were used as research tools. An original questionnaire was also used. The study comprised a representative sample of the female population aged 45-65 living in Lublin Province. The sample size was 2,143 women. Results: The quality of the women’s life was significantly affected by the place of permanent residence. The worst quality of life was found in permanent country dwellers. City and town inhabitants revealed a considerably higher level of quality of life. Permanent place of residence in the country was an independent predictor of a poorer quality of life. Employment as a full-time agricultural worker was an independent predictor of a worse quality of life in the SOM domain of WHQ, as well as RP, RF and RE domains of SF-36. On the other hand, employment as a full-time agricultural worker was an independent predictor of a better quality of life in the SLE domain of WHQ, and psychological domain of WHOQFL-BREF. Conclusions: Awareness of the dependence is necessary in order to effectively plan health education and physical and social health promotion campaigns. Country dwellers need special attention in the process of undertaking any preventive or curative steps
