Indoor air quality monitoring of communities surrounding a coal-fired power plant in Pagbilao, Quezon

OBJECTIVES: The study evaluated the quality of indoor air in households surrounding a coal-fired power plant in Pagbilao, Quezon and its impact to the residents in these communities.  METHODS: The researchers used a quantitative approach and gathered both primary and secondary data from the Province of Quezon, Municipalities of Pagbilao and Padre Burgos and 12 other barangays from January to June 2008. A household survey was conducted to obtain the health and socio-demographic characteristics of the respondents. Likewise, indoor air quality surveys, respiratory health profiling and pulmonary function tests were done. Indoor air quality monitoring measured eight hour levels of particulate matter -10 (PM10) in "near" and "far" barangays and sulfur dioxide (SO2) and nitrogen dioxide (NO2) in two primary impact barangays as indicated in the environmental impact assessment of the power plant.RESULTS AND CONCLUSION: Results showed that there is no significant difference (p=

Development of water safety plan models for water refilling stations in the Philippines

OBJECTIVES: The aim of the project is to develop water safety plan (WSP) guidelines specific for water refilling station (WRS) operators. The guidelines will serve as model for future formulation of WSP among WRS across the country. METHODS: A criteria was developed for selecting WRS. Site visits were initially done along with the selection of eight (8) water refilling stations from pre-identified areas across the country. The operators of the selected WRS together wih their respective local sanitary inspectors underwent a workshop where they were trained and guided on the step-by-step process of devising a WSP. Coaching and mentoring was then conducted for the improvement of the draft WSPs. A guideline manual on how to develop WSPs for WRS was drafted to serve as reference for other WRS in the country. RESULTS: The study developed a WSP model specifically made for WRS setting. Eight (8) final drafts of WSP were also accomplished. WRS operators and local sanitary inspectors were trained on how to develop WSP which will support and facilitate appropriate implementation of these functional WSPs.CONCLUSION: The formulation of WSPs among WRS ensures delivery of safe drinking-water among its consumers. It serves as an initial step in realizing the vision of DOH of institutionalizing WSPs among all water utilities in the country. The guidelines developed will be a useful tool for other WRS in the country for preparing their own WSPs.

Cadmium concentration in brown and polished rice from selected farms in Barangay Real, Calamba City and its potential non-cancer health risk in adult population

OBJECTIVES: This study was conducted to determine the cadmium (Cd) concentration in brown and polished rice collected from the 9 farms in Barangay Real, Calamba City. This study also assessed the non-cancer health risk to adults (?20 years old) of long-term consumption of rice with Cd using the non-cancer hazard quotient (NHQ). METHODS: Rice grains with hull were collected in November-December 2013. Both rice types were analyzed for Cd using a graphite furnace atomic absorption spectrophotometer (GFAAS). The NHQ was calculated by dividing the estimated daily intake of Cd via rice consumption by the oral reference dose (RfD) for Cd.RESULTS: Mean Cd concentrations in brown and polished rice collected from the 9 farms in Barangay Real ranged from 0.0062 to 0.0725 mg/kg and 0.0047 to 0.0778 mg/kg, respectively. The NHQ values of Cd in both rice types were less than 1.0 for adults (?20 years old). CONCLUSION: Cd concentrations in brown and polished rice from the 9 farms did not exceed the 0.4 mg/kg maximum allowable Cd concentration in rice set by FAO/WHO. Since the NHQ did not exceed 1.0, long-term exposure to Cd through consumption of brown and polished rice from these farms is unlikely to cause non-cancer health effects in adults (?20 years old). It is unlikely for adults to develop kidney diseases such as tubular proteinuria, decreased glomerular filtration rates, and itai-itai disease.

Policy alternatives to reduce the health and economic effects of continued asbestos use in the Philippines

OBJECTIVES: Asbestos is a carcinogenic mineral substance formerly used widely in the construction industry, all forms of which, except for chrysotile asbestos, have been banned in the Philippines. This article aims to propose policy alternatives to reduce the health and economic effects of continued asbestos use in the country.METHODS: Records of asbestos-related diseases, and asbestos industry-related data in the country were consolidated. The impact of continued asbestos use on the national economy were estimated incorporating natural mortality, regulations of the Department of Labor and Employment (DOLE), and concepts of multiplier effect and net present value. Round table discussions validated data and generated policy recommendations.RESULTS: Filipinos directly and indirectly exposed to asbestos-containing materials (ACMs) are 5,289 and 30,000, respectively. The contributions of these groups to the national economy were estimated at PhP 1.08 Billion annually for workers directly exposed to ACMs and PhP 6.83 Billion annually for workers indirectly exposed. Two policy options--adjustment of threshold limit values, and a total ban--are presented.CONCLUSION: A total ban on all forms of asbestos is shown to be the more cost-effective policy option for the country. It is recommended that government agencies, stakeholders in the asbestos industry, and the general public be involved in strategies for improving surveillance on asbestos exposure, increasing public awareness, and promoting the use of asbestos alternatives.

Occupational health systems across selected public healthcare facilities in the Philippines

OBJECTIVE: The study aimed to collect data on the occupational health systems implemented across selected healthcare facilities in the Philippines, including: (1) governance system for occupational health and safety (OHS), (2) OHS information systems, (3) OHS financing systems, (4) technology and related systems for OHS, (5) the OHS workforce, and (6) the delivery of OHS services.METHODS: The data were collected through a walkthrough survey of the selected facilities as well as through the review of records and relevant documents found in the facilities.RESULTS: Governance and financing systems for OHS are not present in any of the facilities. 3 out of the 13 hospitals studied have employee medical records, accident/incident reports while none of the 19 facilities have Workplace Environment Monitoring Reports (WEM), implying the lack of OHS information systems. Due to the lack of a financing mechanism for occupational health services, there is a lack of OHS technology in the facilities which include but are not limited to the presence of an Immunization and Post-Exposure Program (present in 7 out of 13 hospitals and none of the 6 RHUs studied). 1 out of 19 facilities reported to having personnel delegated for OHS activities in their facility. Lastly, 1 out of 19 facilities have emergency treatment and medical facilities for their employees, indicating inadequate OHS service delivery in the facilities studied.CONCLUSIONS: Standards and laws such as the Philippine OHS Standards and Department of Health (DOH) Administrative Order (AO) 2012-0020 have provisions with regard to OHS in these facilities, and stricter implementation of these provisions could help in filling in the gaps in the OHS systems in these facilities. This will provide a healthy workforce capable of giving better healthcare services to the general population.

Knowledge and practices of water refilling station owners and operators in providing safe and wholesome drinking water supply in one municipality of Cavite

OBJECTIVES: This study aimed to a) evaluate the knowledge of water refilling station (WRS) owners and operators regarding the proper techniques and procedures applicable to WRS based on the Certification Course for Water Refilling Station and Plant Operators (CCWRSPO); b) assess compliance to regular physical-chemical and microbiological testing of product water and sanitary permit acquisition and c) determine the quality of product water of selected water refilling stations (WRS) in a municipality in Cavite. METHODS: The study includes WRS owners and operators who participated in the CCWRSPO from 2005 to 2009. A 50-item objective examination administered by the researchers was used to evaluate the knowledge of the respondents. This was formulated based on the objectives of the CCWRSPO. The compliance to legal requirements for WRS was assessed according to the results of the physical-chemical and microbiological tests (Multiple Tube Fermentation Technique and Pour Plate Method) and the presence of an updated sanitary permit. Results of product water analyses were compared to the 2007 Philippine National Standards for Drinking Water. Water refilling stations that failed to meet at least one of the three legal requirements were considered as "non-compliant". RESULTS AND CONCLUSION: Results showed that 71.8% of the respondents passed the written examination whereas 28.2% obtained scores less than 50.0%. Chi-square analysis indicated that there was no significant difference between the knowledge of the trainees in 2005 to 2008 and the trainees in 2009. Similarly, majority (78.9%) of the WRS included in the study were found to be non-complaint with the provisions of P.D. 856 and the prescribed standards for water quality. The quality of product water served as an important determinant of the compliance of WRS. Although majority of the water samples tested had acceptable microbiological examination results, 16.9% of the samples exceeded the standards for microbiological water quality. Aside from this, the non-compliance of WRS was attributed to the absence of an updated sanitary permit, which was one of the important indicators of product water quality. Chi-square analysis showed that the trainees who have been operating WRS for only a year after the certification course were less compliant as compared to those operating for two to five years.
