Abstract
Background Household waste of 1.6 million people in Morelos, Mexico, accounting almost 1700 ton/day, which are disposed either in an open dump (93%), or in an landfill sites (7%), with the consequently environmental impacts that affect water, soil and air quality. Aims Pilote study to evaluate the potential worker exposure to envioronmental PM10 and relate it to their health status in the Landfill "Perseverance" in Cuautla, Morelos. Methods Samples of airborne particles (PM10) were collected using miniVol sampler with teflón filters, located in the landfill 2 m above ground level. 23 men workers participate in this study; standarized staff obtained anthropometry data, blood pressure and blood samples previously reading and signing the informed consent letter. Blood samples were analyzed for biochemical factors. Results The workers aged from 18 to 39 years old (P50 = 26). Hemoglobin levels were from 9 to 22 g / dL (p50 = 15.8 g / dL) considering this a low hemoglobin value and 11 samples were above the reference value (16 g / dL). Similar values were found among workers with deshidratation. PM10 average 24h concentrations ranged from 11 to 299 ug/m3. The worker exposure is about 12 h/day (6:00 to 18:00 hours). Conclusions The study group, formed by formal and informal Landfill workers, have similarities health status, customs and lifestyles. This study is an important approach to health impact associated to landfill activities.
