Abstract

This study tries to determine the concentration of sea surface microlayer from different coastal environments (Port Dickson, Negeri Sembilan and Perhentian Island, Terengganu). The concentration of surfactants in both sea surface microlayer and atmospheric aerosols were analysed by using colorimetric method as methylene blue active substances (MBAS) and diethyl violet active substances (DBAS). The results indicated that the concentration of surfactants as MBAS (0.421 +/- 0.040 imol l-1) and DBAS (0.294 +/- 0. 123 imol l-1) were still at the natural concentration level. The flux of surfactants from sea surface microlayer is expected around 2.3 Mmol yr-1 compared to the amount of 1300 Mmol yr-1 surfactants in atmospheric aerosols around marine ecosystem.

Abstract

Scabies is a significant disease for public health because it is a substantial contributor to global morbidity and mortality. The prevalence of scabies worldwide is reported to be around 300 million cases annually. The incidence of scabies in Indonesia is still very high and located in West java. The purpose of this study was to analyze the characteristic risk factors and personal hygiene, as well as to test the sensitivity of these risk factors to the incidence of scabies in Islamic boarding school students. The variable gender has a 2,117 times greater risk, knowledge has a 1,323 times greater risk, bathing habits have a 1.185 times greater risk, cleanliness of clothing has a 1,553 times greater risk of experiencing disease scabies. The results of the meta-analysis that has a greater level of risk in terms of characteristics is the gender variable and the personal hygiene variable that has a greater risk factor is the clothing cleanliness variable. Efforts that can be made by related agencies in the Pondok Pesantren area are to carry out promotive and preventive activities to prevent the occurrence of scabies in Islamic boarding schools.

Abstract

Pesticides used massively in the agricultural sector would cause many poisoning and serious health problems. Organophosphate pesticides have been identified as endocrine-disrupting chemicals. This study aimed to compare thyroid hormone levels between the sprayers chronically exposed to pesticides and the control respondents who had never been exposed to pesticides. This study was an analytical observational with a cross-sectional design. The total number of respondents was 150, 50 as sprayers and 100 as control respondents. The venous blood samples were examined using the Enzyme-Linked Immunosorbent Assay (ELISA). The findings significantly showed that the sprayer had a higher level of thyroid-stimulating hormone (TSH) (4.776 ± 1.1166), lower triiodothyronine (T3) (108.822 ± 18.810), and lower thyroxine (T4) (7.808 ± 1.067). Determinant factors among sprayers that significantly correlated to TSH levels was age (p-value = 0.006); work duration (p-value = 0.000); personal protection equipment (PPE) (p-value = 0.045); body position (p-value = 0.014); type of pesticides (p-value = 0.004), correlated with T3 levels was age (p-value = 0.037); body position (p-value = 0.045), correlated with T4 levels was age (p-value = 0.000); PPE (p-value = 0.045). It could be concluded that chronic organophosphate exposure would increase TSH and decrease T3 and T4.
