Asst. Prof. Carmelita C. Cardona, RMT, MSMT INTRODUCTION
AND SIGNIFICANCE STATEMENT OF THE
PROBLEM AND OBJECTIVES METHODOLOGY RESULTS CONCLUSION
AND RECOMMENDATIONS What is LEAD a bluish-white lustrous metal
very soft, highly malleable, ductile, and a relatively poor conductor of electricity
widely for application in metal products, cables and pipelines, paints, and pesticides
one of the four metals that are detrimental to human health What is the prevalence of lead poisoning in Barangay Saluysoy?
What is the mean blood lead level and the mean water lead level in deep well water in Barangay Saluysoy?
What are the socio-demographic profiles of the respondents in Barangay Saluysoy?
Which of the above factors is associated with increased BLL?
What is the relationship between BLL and deep well water lead level? Table 4.
Mean Bood Lead Level and Mean Water Lead Level in Deep Well Water in Barangay Saluysoy, Meycauayan, Bulacan, November 2012 Table 5.
Prevalence of Lead Poisoning in Barangay Saluysoy, Meycuauyan, Bulacan, November 2012 Table 3.
Distribution of the Deep Well Users in Barangay Saluysoy, Meycauayan, Bulacan, November 2012 Table 2.
Socio-Demographic Factors of the Respondents in Barangay Saluysoy, Meycauayan, Bulacan, November 2012 Table 7.
The Association of an Elevated Blood Lead Level and Sources Drinking Water of the Respondents in Barangay Saluysoy, Meycauayan, Bulacan, November 2012 Table 8.
The Association of an Elevated Blood Lead Level and Uses of Deep Well Water of the Respondents in Barangay Saluysoy, Meycauayan, Bulacan, November 2012 Figure 4. Relationship between Blood Lead Level and Deep Well Water Lead Level Conclusion Prevalence of lead poisoning = 80/100 population at 10ug/dL and 100/100 population at 5 ug/dL
Crowding index and years of residency
Mean blood lead level is 17.44 ug/dL
Mean deep well water lead level is 0.80 ug/L
No correlation Recommendations Table 6.
The Association of an Elevated Blood Lead Level and Socio-demographic Factors of the Respondents in Barangay Saluysoy, Meycauayan, Bulacan, November 2012 THANK YOU FOR LISTENING! =) What is the relationship between Blood Lead Level, and Deep Well Water Lead Level and Other Socio-Demographic Factors in Barangay Saluysoy, Meycauayan, Bulacan? Pearson correlation coefficient = 0.138 food (65%) water (20%) air (15%) 143,000 deaths every year 0.6% of the global burden of disease
(WHO, 2009) a cumulative toxicant that affects multiple body systems
can also harm the fetus because it can cross the placenta (Lenntech, 2011)
Children are particularly vulnerable to the neurotoxic effects of lead, and even low levels of exposure can cause serious and, in some cases, irreversible neurological damage (WHO, 2010) CDC
10 ug/dL 5 ug/dL (Magellan Diagnostics, 2012) SCOPE AND LIMITATION Residents of Barangay Saluysoy,
Meycauayan, Bulacan
Random sampling
Only 50 respondents
Pre-tested questionnaires
Written consent forms
Blood extraction
Deep well water samples inability to measure all pathways of lead intake inability to determine causality Inability to measure the volume of deep well water consumed/used Inability to determine if the elevated BLL is due to primary contamination of water or only due to the corrosion of lead pipes RELATIONSHIP DEEP WELL WATER LEAD LEVEL BLOOD LEAD LEVEL RELATIONSHIP increase sample size and deep well water samples
hematologic examinations
identify source of lead exposure
environmental factors
