Health Risk Due to Carbamate Exposure in Communities Around Paddy Field Areas

Introduction: Carbamate is one of the most widely used pesticides in paddy field areas, which causes environmental pollution and human health problems. Therefore, this study aims to analyze the health risks of carbamate exposure in communities around paddy fields areas. Methods: This was an observational analysis study conducted using the health risk assessment approach. There were 20 samples of waterway streams from 10 sites observed in the morning (at high tide) and evening (at low tide) taken using a grab sampling method. The parameters of the waterway streams river, such as pH and temperature, were measured on-site using a pH meter and portable thermometer, while the carbamate concentration was analysed in the laboratory using High-Performance Liquid Chromatography (HPLC). Results and Discussion: The active ingredients of carbamate pesticides that observed as follows: aldicarb (0 – 0.05 mg/l), carbaryl (0 – 0.01 mg/l), carbofuran (0-0.005 mg/l), and propoxur (0-0.001 mg/l). While the pH (6.4 – 7.5) and temperature (22.1 – 32.4oC). The potential exposure of Aldicarb in grown-up and kids were 0.042 and 0.077 mg/kg bodyweight-day, respectively. Furthermore, the potential exposure of carbofuran in Grown-ups and kids were 0.004 and 0.01 mg/kg bodyweight-day, respectively. Only the carbofuran exposure in kids has a rate of RQ > 1, which is unsafe or can cause non-carcinogenic effects in the next 30 years. Conclusion: Although the carbamate concentrations in waterway streams around paddy field areas were below the quality standard, it is not safe. Therefore, it is necessary to carry out risk management and communication with local policymakers.

Household Sanitation as a Diarrhea Driving Factor of Under-Five Children in Bojonegoro Regency

Introduction: Diarrhea incidence in children under five increases by 11% in Indonesia during 2013 - 2018 that could be driven by poor environmental sanitation. This study examined the relationship between environmental sanitation with diarrhea incidence in children under five. Methods: This study was an observational study with a cross-sectional design and used a total sampling technique of 81 underfive children. Primary data were collected by conducting interviews with parents using a structured questionnaire guideline and observation, including the source of drinking water, availability of healthy latrine, floor condition, and lighting. A Chi-square test (α = 0.05) was conducted to analyse the relationship between variables. Results and Discussion: There was a significant correlation between household sanitation and diarrhea incidence in under-five children (p = 0.040; PR = 1.202 [95% CI 0.987 – 1.463]). Conclusion: Poor household sanitation can be a driving factor in diarrhea incidence in under-five children, where households categorised as good sanitation have 1.2 times lower risk than poor sanitation

Malaria Vector Control and the Electronic Malaria Surveillance Information System (E-SISMAL) in Bangka Barat Regency Indonesia

Introduction: Until the end of 2020, West Bangka Regency was the only one that has not been certified for malaria elimination, so that it has an impact on achieving malaria elimination at the provincial level of Bangka Belitung. The West Bangka Regency's Electronic Malaria Surveillance Information System (E-SISMAL) showed eight indigenous malaria cases and no malaria vector control reports in 2020. The indigenous cases in West Bangka Regency have prevented malaria elimination. This study aims to evaluate malaria vector control to help eliminate malaria. Methods: This research was a qualitative evaluation study with selected informants. E-SISMAL in West Bangka Regency was studied and was analysed with Nvivo 12 Plus for Windows. The variables studied were context, input, process, and product. Focus groups, in-depth interviews, participatory observation, and photovoice were used to collect data. Results and Discussion: The area's topography, miner's behaviour, lack of manual vector reporting, and extensive ex-mining pits were discussed. Each evaluation variable was constrained by the process (supporting data collection and sub-variables) and product (data coverage of malaria vector control in E-SISMAL). Conclusion: It can be concluded that each evaluation variable constrains malaria vector control in West Bangka Regency.

Impact of Climate Change on Dengue Hemorrhagic Fever (DHF) in Tropical Countries: A Literature Review

Introduction: Dengue Hemorrhagic Fever (DHF) is a zoonotic disease that is most wary because the cases reported by WHO increased quite drastically from 2.4 million cases to 5.2 million cases in 2010-2019 globally. In 2020, the DHF rate increased by 953,476, and the majority occurred in tropical countries. In response to this, WHO emphasized that climate and weather variables can play an important role in predicting the DHF outbreak. This article was written to find out the impact of climate change on the incidence of DHF. Discussion: The literature review method was used in writing this article by utilizing article searches in online databases, namely PubMed, DOAJ, Proquest, and Science Direct. Amount 11 articles related to the title have been selected as literacy materials. Climatic variables consisting of temperature, rainfall, and humidity have the potential to increase the incidence of DHF. Conclusion: It can be concluded that climate change indicators can affect the breeding place of the Aedes aegypty, making the various incidence of DHF cases in tropical or subtropical countries. This can be an early warning for each region always to carry out active surveillance in detecting the risk of increasing DHF cases in certain weather.

Risk Factors of Anthrax Transmission in Pacitan Regency

Introduction: Anthrax was a zoonotic disease caused by the bacterium Bacillus anthracis in several regions of Indonesia. Transmission of anthrax in animals and humans occurred by direct contact with anthrax spores present in meat, soil, or plants. This study aimed to analyse the risk factors and recommend preventive action for anthrax transmission. Methods: This research used a descriptiveanalytic study to describing cases based on the case definition, primary data, and secondary data. The primary data were collected from the field observations and interviews with farmers and people in the community. The secondary data were obtained from the Pacitan District Health Office and Surabaya Technical Centre for Environmental Health and Disease Control. Data analysis of this study applied content analysis techniques that describe the actual situation of the community. Results and Discussion: Risk factors for anthrax transmission in Pacitan Regency included livestock traffic from endemic anthrax areas and lacked public knowledge about anthrax disease, rainfall, and topography. Conclusion: Anthrax disease control measurements include surveillance and investigation periodically, treatment of the suspected livestock, vaccination, disinfection, and socialisation. The government needs to control livestock traffic by providing proper regulation. Also, the public might improve knowledge and awareness with their livestock

Human Leptospirosis Outbreak: A Year After the ‘Cempaka’ Tropical Cyclone

Introduction: The ‘Cempaka’ Tropical Cyclone hit south Java in November 2017, causing heavy rainfall and severe flooding. Changes in climate variability and extreme weather events may shift the geographic and seasonal patterns of neglected tropical diseases such as leptospirosis. This study analyses the Spatiotemporal pattern between flooding, weather, and human leptospirosis cases after a tropical cyclone. Methods: This was an ecological study that collected monthly flooding data, weather data, and human leptospirosis data cases per village from November 2017 to October 2018, a year after the ‘Cempaka’ Tropical Cyclone in Bantul. Spatio-temporal analyses were calculated to 0-3 months lag by Pearson's correlation, spatial mapping, and time-series graphs. Results and Discussion: As many as 99 people infected with leptospirosis were found in all 75 villages in Bantul. The villages affected by flooding were 44% and leptospirosis cases spread in 68% of villages. A 1-month lag (r = 0.6849; p < 0.05) and 3-months lag (r = 0.6666; p < 0.05) of relative humidity along with a 1-month lag (r = 0.7451; p < 0.05) and 3-months lag (r = 0.8561; p < 0.05) of rainfall were found to be correlated to human leptospirosis cases. Heavy rain due to the Cempaka Tropical Cyclone caused flooding and transmission of Leptospira bacteria into the water and heightened contact between humans, animals, and the environment. Conclusion: It is found that flooding, relative humidity, and rainfall after the Cempaka Tropical Cyclone would be followed by human leptospirosis outbreaks 1 and 3 months later. Cross-sectoral cooperation of public health authorities should integrate climatic information as an early warning for disaster-prone areas and community groups at risk.

Determinants of Persistent Organic Pollutants (POPs) Levels in Human Specimens: A Review

Introduction: Numerous studies have been conducted regarding persistent organic pollutants (POPs) concentrations in human biological matrices such as blood, breast milk, urine, and hair that cause adverse health effects such as breast cancer, cardiovascular diseases, and type 2 diabetes. This study aimed to determine the POPs presence in human specimens in household settings. Discussion: A total of 28 articles were included in this study with the criteria published in 2016- 2021, original research articles, free full text available, and studied at least one of the confounding variables of POPs levels in human specimens. The narrative method was selected to synthesize this study. Grouping articles with similar results was carried out to respond to research questions. This study discovered that age, dietary habits, BMI, sex, race/ethnicity, smoking status, physical activities, residency, household dust, and industry emissions were associated with POPs levels in human specimens. Conclusion: This study concluded that each determinant could not affect the POPs levels in the human specimens on its own since those determinants are influenced by each other. Future research using systematic literature review and meta-analysis is therefore strongly advised.

Health Risks Assessment of Heavy Metal from Consumption of Oreochromis Mossambicus and Oreochromis Niloticus in Denpasar, Bali

Introduction: Heavy metals in the environment can accumulate in organisms through the food chain process. Previous studies recorded heavy metal concentrations above threshold limits value in Badung river, which warrants monitoring adverse health outcomes due to consuming fish from this river. This research aimed to estimate the potential risk from heavy metals exposure, namely Pb, Cd, Cu, and Cr, due to fish consumption. Methods: Fish samples were limited to Oreochromis Mossambicus and Oreochromis niloticus, commonly known as tilapia. Twenty samples of composite fish muscles were collected from three fishing sites. Subsequently, the heavy metals present in the samples were quantified using an atomic absorption spectrophotometer (AAS), and health risks were assessed by calculating estimated daily intake (EDI) and target hazard quotient (THQ) for both carcinogenic and non-carcinogenic risks. Results and Discussion: The average concentrations of Pb in Oreochromis Mossambicus (6.35±3.21 mg/kg) and Oreochromis niloticus (6.09±3.07 mg/kg) exceed the threshold limits value for fish products, but other heavy metals remain below. The average EDI from consuming Oreochromis Mossambicus with Pb is 0.0025-0.0026 mg/kg/days; Cu is 0.0037- 0.0062 mg/kg/day; Cr is 0.0001 mg/kg/day. EDI from consuming Oreochromis niloticus with Pb is 0.0015-0.0025 mg/kg/day; and 0.00 mg/kg/day for Cu and Cr. The THQ calculation for carcinogenic and non-carcinogenic health risks showed no health risk from consuming the fish from the Badung River. Conclusion: The study concludes that the consumption of Oreochromis Mossambicus and Oreochromis niloticus from the Badung River was generally safe from potential health risks.

Literature Review: Health Impact of Coal Combustion Emissions in Power Plant on Adult Respiratory Systems

Introduction: Coal-fired power plants contribute to air pollution emissions of nearly one-third of global SO2 , 14 % of NOx , and 5 % of PM2.5. This condition could worsen adults’ respiratory health who live close to power plants; WHO estimates that COPD and LRTI cause around 18% of premature deaths related to outdoor air pollution. This literature review aims to conduct a systematic review of the health impacts of coal-fired power plant emissions on adults’ respiratory systems and explore what risk factors lead to decreased lung status. Also, to answer how risk factors influence decreased lung function in adults’ respiratory system from coal-fired power plants’ emissions. Discussion: This study used a literature study method using an online database to of various research data sources with the same topic. The searching of articles was performed based on the inclusion criteria. From an initial collection of 468 articles, after screening and considering its feasibility, four articles were obtained to serve as material for the final systematic review. The literature review showed that there had been a change in lung function of respiratory system of adults due to long-term exposure to emissions from coal-fired power plants. Factors that influence decreased lung function in adults were NOx and SO2 exposure levels, residence distance, wind direction, age, and smoking status. Conclusion: Future research should focus on improving models for assessing exposure to NOx , SO2 , PM10 and PM2.5, considering age and smoking habits in evaluating lung function.

Mapping of Diarrhea in Toddlers with Open Defecation Free (ODF) Status in Tuban Regency

Introduction: The Tuban Regency Health Profile in 2019 stated that the villages with ODF status had reached 64 villages (19.5%) out of 328 total villages, while the villages reported having implemented Community-Based Total Sanitation (CBTS) have reached 100%. The low ODF status achieved indicates that most people still defecate openly, which will increase health risks due to environmental pollution. This study aimed to determine the distribution map of diarrhea in toddlers in each district of Tuban Regency in 2019. Methods: This study was an observational research type supported by mapping through an application with a cross-sectional research design. This study was all districts in Tuban Regency. Data were obtained from secondary data, which were the Tuban Regency Health Profile in 2019. Results and Discussion: The percentage of latrine ownership was 71.15%, the open defecation was 70%, the percentage of children under five was not more than 14.69%, and cases of diarrhea among toddlers were relatively diverse in each district with the lowest number of cases was 0, and the highest number of cases was 841. Conclusion: Diarrhea in toddlers was commonly distributed in the Eastern and Southeastern Tuban Regency, directly adjacent to the Bengawan Solo River. There was a strong possibility that the occurrence of diarrhea was related to the water quality of Bengawan Solo River that was consumed for daily household activities.
