Abstract

Thyroid hormone is vital for children's growth and metabolism, relying on sufficient iodine levels for synthesis. Maternal intake determines iodine supply to fetuses and children under two years old. This study aimed to correlate offspring thyroid function with maternal iodine status in coastal areas. A cohort study was conducted, involving pregnant coastal residents. Maternal urinary iodine levels were measured via the ammonium persulfate method, while offspring thyroid stimulating hormones (TSHs) and free thyroxine hormone (fT4) levels were assessed using electro-chemiluminescence immunoassay (ECLIA). Iodine intake was determined through a semiquantitative food frequency questionnaire (FFQ). The correlation between offspring thyroid function and maternal iodine status was analyzed using Pearson’s correlation test. Differences in TSHs and fT4 levels among iodine status groups were examined using the One way-ANOVA test. Maternal iodine status was insufficient with a median urinary iodine of 125 μg/L, resulting in a 60.8% prevalence of iodine insufficiency. Iodine intake (62.20±43.45 μg/day) fell short of recommended levels (RDA). Offspring TSH was 2.29±1.07 μIU/mL, fT4 was 1.26±0.14 ng/dL. TSH and fT4 concentrations showed no significant inter-group differences (p=0.852, p=0.075). Offspring thyroid function did not correlate with maternal iodine status (TSHs: p=0.314; fT4: p=0.258). Offspring thyroid function did not correlate to maternal iodine status in a population of iodine-insufficient and mercury-contaminated coastal areas.

Abstract

The immune response to mercury is unique, it can be immunosuppressive and immunomodulative. The immune response to mercury begins with exposure to mercury from the environment originating from natural activities such as volcanic activity and human activities such as gold processing from artisanal small scale gold mining and chlorine alkali factories, or from consumption mercury- contaminated fish. These mercury sources release inorganic and organic mercury which enters the human body through inhalation, ingestion and absorption through the skin. The entry of mercury into the body will induce innate and adaptive immune responses. The immune response to mercury is immunomodulative and triggers proinflammatory substances production. This mechanism is the pathological basis for clinical manifestations of mercury intoxication in the kidneys, central nervous system, respiratory tract and skin.

Abstract

Stunting is a condition where a child experiences a lack of nutritional intake which causes growth disorders such as height below the standard of children of the same age in a toddler. Stunting can be caused by multifactors, including food consumption that is less nutritious. Sekotong sub-district is one of the marine product producing areas in West Nusa Tenggara, however the prevalence of stunting among children aged 6 months to 2 years in this area is still above the stunting threshold set by the Ministry of Health of the Republic of Indonesia. Therefore, it is necessary to shifting knowledge and lifestyle to targeted communities to reduce the risk of stunting in Sekotong District with the aim of educating the community and creating new good habit patterns.  This activity was carried out using the FRES&P method (Family, Refreshing, Education, Sociality, and Presentation) to 42 people involved in the community including health cadres in the Sekotong Health Centre working area. The activity was carried out by providing exposure to material where an assessment of understanding was carried out before and after the exposure was carried out. In between activities, games related to the material were given to make it easier for participants to understand the material. In addition, the distribution and explanation of the material in the BESTI PADU booklet was carried out by applying ‘Matur Tampiasih’ to all participants present. This booklet is expected to be one of the learning tools for participants during the activity and when returning to their homes. The activity went smoothly and received good enthusiasm as evidenced by the various questions given by the participants. In addition, based on the results of the analysis of questionnaires distributed to participants, it was found that there were changes in the level of understanding resulting from the activity. The FRESH&P method can be one of the socialisation methods regarding stunting. Therefore, it can be concluded that the educational method provided can increase public understanding of stunting.

Abstract

Gold mining that uses mercury in coastal areas exposes various mercury species to the environment and humans living in contaminated areas. The mercury species that reach the population in these areas include elemental mercury, inorganic mercury, and organic mercury. The mercury cycle from gold mining begins with the release of elemental and inorganic mercury into the sea. The bioaccumulation and biomagnification of organic mercury in the ocean will expose coastal populations to methylmercury. The exposure routes of mercury to humans from these different mercury species vary, including through the skin, respiratory system, and digestive system. Organ damage and clinical symptoms that appear depend on the affinity of the mercury species for specific organs. Symptoms of intoxication can range from central nervous system dysfunction, kidney damage, and a spectrum of disorders in other organs.

Abstract

This study aimed to evaluate the effectiveness of cryogenic grinding as a hair sample preparation technique and to compare heavy metal analysis results obtained using Energy Dispersive X-ray (EDX) and Atomic Absorption Spectrophotometry (AAS). Hair samples were collected from five residents of Sekotong and analyzed for Cd, Hg, and Pb content. Data were analyzed descriptively and compared using the Friedman test. The results indicated that AAS consistently yielded higher metal concentrations than EDX. Cd concentrations measured by AAS, EDX of powdered hair, and EDX of intact hair were 0.00656 mg/kg, 0.00130 mg/kg, and 0.00010 mg/kg, respectively. For Hg, the corresponding measurements were 0.00380 mg/kg, 0.00212 mg/kg, and 0.00362 mg/kg, whereas Pb exhibited the largest disparity, with 0.12930 mg/kg for AAS, 0.00224 mg/kg for EDX of powdered hair, and 0.06978 mg/kg for EDX of intact hair. The high variability, particularly in Pb measurements, suggests that heterogeneity in metal distribution and surface contamination affect EDX readings of intact hair. Cryogenic grinding yielded a more homogeneous particle distribution, resulting in EDX measurements of powdered hair that were more representative and numerically closer to AAS results than measurements of intact hair. Although differences were not statistically significant (p > 0.05), these findings support the use of cryogenic grinding to enhance the accuracy of hair-based heavy metal analysis. Furthermore, this method has the potential to reduce the use of destructive chemicals and hazardous waste, making it a safer and more sustainable alternative for community biomonitoring in areas affected by heavy metal contamination.
