Abstract

Anchovy is widely used in many dishes and are among the most consumed marine fish among Malaysians. Anchovies are one of the marine organisms that can accumulate pollutants including heavy metals. Numerous studies were conducted to minimize the heavy metals concentration in seafood such as various cooking and processing methods, and advanced treatments with the aid of chelating agents. Among the effective methods to remove heavy metals from seafood is by chelating techniques. Previous research conducted showed that the removal of heavy metals from seafood with nanomaterials such as chelating agents enhances the quality of the seafood with reduced heavy metals concentration as well as minimum purification costs. In this research, combination of trisodium citrate and peracetic acid were used as the chelating agent to perform a series of optimization treatments to remove toxic heavy metals including arsenic (As), lead (Pb), cadmium (Cd), and chromium (Cr). The optimization treatment was conducted by using Box-Wilson central composite design (CCD) which is a model in response surface methodology (RSM). Among the parameters that were optimized in this study are temperature between 29.0 to 37.0℃, pH between 3 to 7, treatment time between 5 to 60 minutes, and dosage of chelating agent between 1000 to 2000 mL/Kg. The anchovy samples were prepared according to a method adopted from AOAC 999.10 standard method for elements cadmium, lead, arsenic, and chromium. Inductively coupled plasma optical emission spectrophotometer (ICP- OES) was used to determine the heavy metals concentration in untreated and treated anchovy samples. Analysis of variance (ANOVA) showed all the four models designed are significant and influence the percentage removal of heavy metals. The Design-Expert software based on CCD RSM suggested a total of 97 solutions according to the four independent variables. Based on the solutions suggested, an optimized condition selected with highest desirability at 0.644 with percentage removal of arsenic at 77%, lead 39%, cadmium 54%, and chromium 18%.

Abstract

Eggs are important component of human diet worldwide. They provide the human body with diverse array of substances including metal elements. Due to pollution the eggs can incorporate metals at levels that are harmful. Thus, the objective of this work was to determine the levels of Ca, Mg, Fe, Zn, Cd, Pb, and Cr in eggs in Sokoto, Nigeria and health risk therewith. The metals were determined using atomic absorption spectroscopy. The results reveal, significantly (p<0.05) different concentrations of metals in commercial/ exotic and local chicken eggs in Sokoto, Nigeria as follows: The zinc (Local: 35.0 ± 1.5 ppm, Exotic: 30.12 ± 2.6 ppm) metal is the most elevated metal, followed by magnesium (Local:15.0 ± 0.05 ppm, Exotic:10.02 ± 1.5 ppm), then iron (Local: 7.0 ± 0.001 ppm, Exotic: 4.02 ± 0.001 ppm), then calcium (Local: 6.21 ± 0.01 ppm, Exotic: 5.01 ± 0.005 ppm). Others lower levels of metals are recorded by chromium (Local: 3.01 ± 0.05 ppm, Exotic: 4.51 ± 0.05 ppm), cadmium (0.061 ± 0.001 ppm detected in Exotic), and lead (Local: 0.05 ± 0.002 ppm, Exotic: 0.20 ± 0.002 ppm). The levels of essential metals found in eggs in this study are low, and levels of Cr, Cd, and Pb in exotic eggs are elevated. Similarly, health risk assessment result shows a public health concern. Care needs to be taken when consuming eggs by the public.

Abstract

Dengue Hemorrhagic Fever (DHF) is a disease caused by the Dengue virus which is transmitted through the Aedes aegypti mosquito. DHF is caused by the Dengue virus whose main vector is the Aedes aegypti mosquito and the secondary vector is the Aedes albopictus mosquito. Eradicating Aedes aegypti and Aedes albopictus is one way that can be done to prevent the spread of the Dengue virus. Control of the dengue vector can be carried out on larvae and adult mosquitoes with the aim of breaking the chain of transmission. One way that can be done is by using a natural larvicide which utilizes the Allium fistulosum plant which contains secondary metabolite compounds including phenolics, flavonoids and tannins which can kill larvae. This study aims to determine the comparison of variations in the concentration of Allium fistulosum leaf extract on the mortality of Aedes aegypti instar III. The type of research used in this research was experimental with a completely randomized design (RAL). The potential level of the extract is reviewed from the Lethal Concentration (LC50) and Lethal Time (LT50) values. The data obtained were analyzed using a probit regression test or probit analysis to determine the potential of Allium fistulosum extract as an alternative larvicide for third instar Aedes aegypti larvae and stated as Lethal Concentration (LC50) and Lethal Time (LT50) with a confidence level of 95.0%. The results of the research show that Allium f istulosum leaf extract has the potential as an alternative larvicide for the death of third instar Aedes aegypti larvae as proven by a p-value of 0.000 (< 0.05) with a value of LC50-6 hours is 52.850%, LC50-8 hours is 42.674%, LC50-24 hours is 30.900%, LT50-20% is 37.674 hours, LT50-30% is 24.423 hours and LT50-40% is 14.954 hours.

Abstract

Synthetic insecticides containing highly effective active substances such as DEET (N,N-diethyl-meta toluamide) to prevent and control Dengue Hemorrhagic Fever can have adverse effects on health and the environment. Kawista leaves (Limonia acidissima) have the potential as a natural insecticide against Aedes aegypti mosquitoes because they contain secondary metabolite compounds namely phenols, flavonoids, saponins, and terpenoids. This study aims to determine the effectiveness of the repellent power of kawista leaf extract (Limonia acidissima) against Aedes aegypti mosquitoes. This study used experimental method with post-test only control group design. The sample used was 25 adult of Aedes aegypti mosquitoes in each treatment. The ethanol extract of kawista leaves was made in the form of a spray with a concentration of 25%, 50% concentration, and 75% concentration. The 25% concentration, 50% concentration, and 75% concentration of kawista leaf extract have an effective repellent power against Aedes aegypti mosquitoes, namely 15.22%, 46.20%, and 70.08%, respectively. The results of the analysis of kawista leaf extract against Aedes aegypti mosquitoes obtained ED50 (Effective Dose 50) at a concentration of 60.343% and ED99 (Effective Dose 99) at a concentration of 124.452%. From the results of the study, it can be concluded that kawista leaves have the ability to repel Aedes aegypti mosquitoes.

Abstract

Scabies is a disease that attacks the skin in humans, a disease caused by the mite, included in the ovoid Arthropod organism. Personal hygiene is a way to maintain health and cleanliness of the body with self-care, therefore the better a person maintains personal hygiene, the less exposure to mites that enter the skin, if someone does not maintain personal hygiene, it will be very easy to get scabies. This study aims to determine the relationship between personal hygiene and the manifestation of mites using the burrow ink test method on students at the Islamic Boarding School in Sidoarjo City. The method used is an observational type that is analytical using a cross-sectional design. A sample of 45 samples in March 2024. The sampling method was carried out using a non-probability sampling method. The samples were examined using the burrow ink test method and continued with skin scraping examination. The results of the examination of 45 samples showed that there were 9 respondents in the good category of personal hygiene clothing cleanliness with a positive scabies examination of 27 (60%) and there were 25 respondents in the poor category of personal hygiene clothing cleanliness with a negative scabies examination of 41 (91%). The results of statistical analysis from the chi-square test, the personal hygiene variable with the manifestation of mites produced a p-value = 0.157 which means there is no significant effect. In this study it can be concluded that there is no relationship between personal hygiene using the burrow ink test method and the incidence of scabies in Islamic Boarding Schools in Sidoarjo City.

Abstract

Rainwater is one of the vital natural resources which plays crucial role in water cycle. Rainwater harvesting is a water conservation technique in which rainwater is captured and stored for various purposes. Despite being an excellent practice, rainwater harvesting does come with some challenges. As poor quality of harvested rainwater due to several natural and anthropogenic activities is one of such limitations, the current study was aimed to assess the water quality of harvested rainwater in Vavuniya south, Sri Lanka. For this study 189 samples were collected from Vavuniya south and the water quality parameters such as color, turbidity, coliform, E. coli, electrical conductivity (EC) and pH were analyzed. Further the recorded water quality data were mapped using ArcMap 10.8 software. Among the 189 water samples, 88% showed color below 1 Hazen while 12% showed color level above 1 Hazen. Notably, 7% of the samples exceeded a color value of 15 Hazen. Regarding the turbidity, 99% of the samples exhibited below 5 NTU. Out of the 189 water samples, 23% showed 0 Nos/100 mL coliform whereas 77% had coliform counts more than 3 Nos/100 mL. At the same time 57% of samples showed E. coli count lower than 10 Nos/100 mL among which 52% samples showed 0 Nos/100 mL numbers of E. coli. Among the 189 water samples, 43% samples showed E. coli numbers above 10 Nos/100 mL. Further, 95% samples showed EC below 200 µS/cm and 5% of the samples showed EC above 200 µS/cm. In addition, majority of the samples (80%) fell within the pH range of 6.5 to 8.5 while remaining 15% showed pH below 6.5 and 5% showed pH above 8.5. Based on the study, soil dust particles, fecal contamination, metal rooftops and emissions from development activities were found as possible causes for recorded poor harvested rainwater quality in some areas. Moreover, the samples analyzed from areas namely South Paravakkulam, Periya Ulukkulama, Avusathapittiya, Rangethgama, Kalukunnamaduva, Alagalla and Eratperiyakulama exceeded the standard range of water quality for at least two parameters. Therefore, regular maintenance and monitoring are required in these areas to ensure safe consumption of rainwater for various uses.
