Abstrak: Kontaminan timbal dapat memberikan efek negatif bagi kesehatan manusia. Kandungan timbal dalam darah ibu hamil dikhawatirkan akan berdampak buruk bagi janin. Di Kabupaten Bogor pada tahun 2014, BBLR berada diurutan pertama dari dua puluh satu pola penyakit kasus rawat inap di rumah sakit golongan umur 0 - < 1 tahun dengan kasus baru sebesar 1.801 jiwa (24, 45%). Desa Cinangka merupakan lokasi dari kegiatan peleburan aki bekas ilegal yang marak dilakukan sejak tahun 1978 dan telah terkonfirmasi sebagai sumber pencemaran timbal.

Tujuan penelitian ini untuk menganalisis pengaruh timbal dalam darah ibu hamil terhadap berat badan lahir bayi. Dilaksanakan di Desa Cinangka, Kec.Ciampea, Kab.Bogor pada Januari - Juni 2016 dengan desain kohort prospektif terhadap 31 ibu hamil. Proporsi ibu hamil yang terpajan timbal melebihi dari batas aman yang ditetapkan oleh WHO, yaitu 10 μg/dl adalah sebesar 51.6%.

Hasil analisis bivariat menunjukkan hubungan yang sangat kuat antara kadar timbal dalam darah ibu dengan berat badan lahir bayi dan berpola negatif, artinya semakin tinggi kadar timbal dalam darah ibu, maka semakin rendah berat badan lahir bayi (r= -0,880) dengan nilai p < 0,001. Model akhir dari analisis multivariat diperoleh koefisien B untuk variabel kadar timbal sebesar -60.264. Artinya, Setiap kenaikan kadar timbal dalam darah ibu sebesar 1 μg/dl, maka berat badan lahir bayi akan turun sebesar 60,264 gram setelah dikontrol variabel umur, pendapatan, dan kadar hemoglobin. Diperlukan upaya mengurangi pajanan timbal dengan menghentikan kegiatan peleburan aki bekas yang masih beroperasi, memberi penyuluhan pada masyarakat tentang bahaya dan dampak pencemaran lingkungan khususnya timbal, dan melanjutkan program enkapsulisasi tanah tercemar timbal.

Lead contaminant may give negative impact for human health. Lead substance ina mother's blood feared would be bad for the health of fetus. In Bogor Regency in 2014, LBW was a number one out of twenty one disease patterns case of hospitalized patient aged 0 - < 1 years old with new case of 1.801 people (24.45%). Cinangka Village is a place for illegal smelting batteries since 1987, and it has been confirmed as lead-contamination source.

This research aims to analyze the impact of lead in pregnant woman's blood towards the baby's birthweight. The research was conducted in Cinangka Village, Ciampea District, Bogor Regency in January - June 2016 using the prospective cohort design with 31 pregnant women as respondents. The proportion of pregnant women exposed to lead that exceeds the safe limit stipulated by the WHO, which is 10 μg/dl, is 51.6%.

The bivariate analysis result indicates that there is indeed a strong relationship between blood lead level of the mothers' and the baby's birthweight, and it is inversely related: the higher the blood lead level of the mothers', the lower the baby's birthweight (r= -0,880) with value of p < 0,001. In the final model of multivariate analysis, it is discovered that the coefficient B for lead level variable is -60.264, which means that for each increase in the level of lead in the blood of mothers by 1 g / dl, the baby's birthweight will decrease by 60.264 grams after controlled by age, income, and hemoglobin concentration. Serious efforts need to be done to reduce the exposure to lead by stopping the smelting batteries activities, providing counseling for the people regarding the danger and impact of environmental pollution, particularly lead, and continuing the lead contaminated soil encapsulisation.

Abstrak: Merkuri (Hydragyrum) adalah logam berat berbahaya yang terbentuksecara alamiah dan aktivitas manusia dapat menimbulkan pencemaran lingkungandan gangguan kesehatan pada manusia. Dampak merkuri yaitu keracunan akut(gangguan pada alat pencernaan, kulit dan saraf) dan kronis (tremor danparkinsonisme). Saat ini pencemaran logam berat merupakan ancaman yang besarbagi lingkungan sehingga harus dikendalikan keberadaannya agar tidakmelampaui batas.Penelitian ini bertujuan untuk mengetahui keracunan merkuri terkaitkonsumsi ikan pada masyarakat di kawasan pertambangan emas skala kecil(PESK) Desa Lebaksitu Kecamatan Lebakgedong Kabupaten Lebak ProvinsiBanten.Jenis penelitian analitik, desain penelitian cross sectional. Variabel terukuradalah konsumsi ikan, karakteristik responden dan kadar merkuri pada rambut.Populasi penelitian adalah masyarakat Desa Lebaksitu dan sampel berjumlah 60orang. Data dianalisis dengan uji chi-square, mann-whitney dan regresi logistik.Hasil Penelitian, prevalensi kejadian keracunan merkuri pada masyarakatsebesar 51,7%, konsumsi ikan masyarakat (konsumsi tinggi) 55%. Konsumsiikan, usia, jenis pekerjaan, lama tinggal, jarak rumah dan sumber air minumberhubungan signifikan terhadap keracunan merkuri. Sedangkan jenis kelamindan status merokok tidak berhubungan signifikan terhadap keracunan merkuridengan sumber air minum sebagai faktor risiko dominan yang dapatmempengaruhi konsumsi ikan terhadap kejadian keracunan merkuri (OR =14,693, 95% CI=1,818-118,769).Kata kunci : Ikan, Merkuri, Rambut

Mercury (Hydragyrum) is a harmful heavy metal naturally occurring andhuman activities, can cause environmental pollution and health problems inhumans. The impact of mercury poisoning are acute (disorders of the digestivesystem, skin and nerves) and chronic (tremor and parkinsonism). Currently heavymetal pollution is a major threat to the environment and should be controlled so asnot to exceed the limits of its existence.This research aims to knowing mercury poisoning related to consumptionof fish to the community in the area of small-scale gold mining (SSGM) DesaLebaksitu Kecamatan Lebakgedong Kabupaten Lebak Provinsi Banten.Type of research was analitic, cross-sectional study design. Measurementof the consumption of fish, the characteristics of respondent and mercury levels inhair. The population research is the community Desa Lebaksitu and a sample of60 people. Data were analyzed by chi-square test, mann-whitney and logisticregression.The result showed, the prevalence of mercury poisoning in the communityof 51.7%, consumption rate (high consumption) 55%. Consumption of fish, age,occupation, length of stay, distance from the house and the source of drinkingwater were significant correlation to mercury poisoning. While Smoking and sexcorrelation insignificant toward mercury poisoning. Source of drinking water isthe most dominant risk factors that may affect the consumption of fish againstmercury poisoning (OR = 14,693, 95% CI=1,818-118,769).

Abstrak: Otak merupakan target utama pajanan merkuri yang dapat mengganggu organ lain karena merkuri organik merupakan neurotoksik yaitu racun terhadap sistem saraf pusat terutama pada bagian korteks dan serebellum sehingga dapat menimbulkan gangguan keseimbangan tubuh. Salah satu sumber pencemaran terbesar merkuri berasal dari pertambangan emas skala kecil (PESK) yang dilakukan oleh masyarakat. Penelitian ini bertujuan untuk mengetahui hubungan antara kadar merkuri dalam rambut terhadap gangguan keseimbangan tubuh pada masyarakat terpajan merkuri. Desain studi yang digunakan adalah cross sectional, pemilihan sampel menggunakan sistem teknik total sampel dengan data kadar merkuri dalam rambut menggunakan data sekunder penelitian sebelumnya. Jumlah sampel dalam penelitian ini adalah 58 responden. Pengukuran gangguan keseimbangan tubuh menggunakan tes Romberg. Hubungan antara kadar merkuri rambut, gangguan keseimbangan tubuh dan karakteristik individu (umur, pekerjaan, lama tinggal, indeks massa tubuh dan konsumsi ikan) diuji menggunakan regresi logistik, chi square dan independen t test. Hasil menunjukkan kadar merkuri rambut yang melebihi batas normal > 2 ppm sebanyak 31 orang (53,4%) dan yang mengalami gangguan keseimbangan tubuh pada masyarakat sebanyak 37 orang (63,8%). Secara statistik terdapat hubungan yang signifikan antara kadar merkuri rambut dengan gangguan keseimbangan tubuh dengan p value 0,010 sebanyak 25 orang (80,6%) responden dengan kadar merkuri > 2 ppm mengalami gangguan keseimbangan tubuh. Responden dengan kadar merkuri > 2 ppm, berisiko mempunyai gangguan keseimbangan tubuh sebesar 6 kali dibandingkan responden dengan kadar merkuri rambut ≤ 2 ppm setelah dikontrol variabel umur. Untuk penelitian berikutnya disarankan untuk melakukan pengukuran udara disekitar lokasi PESK sebagai referensi pajanan merkuri yang masuk melalui jalur inhalasi.

Brain is the main target of mercury exposure that can interface other organs because organic mercury is a neurotoxic that is toxic to the central nervous system, especially in the cortex and cerebellum so can cause disturbance of the body's balance. One of the largest sources of mercury contamination come from artisanal and small scale gold mining (ASGM) conducted by the community. This study aims to determine the relationship between levels of mercury in hair against body balance disorders in community exposed to mercury. This study used cross sectional design, sample selection used total sampling technique. Data of mercury levels in hair used secondary data from previous research. The number of samples in this study were 58 respondents. Measurement of body balance disorders using Romberg test.. The relationship between mercury level in hair, body balance disorders and individual characteristics (age, occupation, length of stay, body mass index and fish consumption) were tested using chi square, independent T test and logistic regression. The results showed hair mercury levels exceeded normal limits of> 2 ppm as many as 31 people (53.4%) and those with disturbance of body balance in community were 37 people (63.8%). Statistically, there was a significant correlation between hair mercury level with body balance disorder (p value 0.010), proved by as many as 25 people (80,6%) respondents with mercury level >2 ppm had disturbance of body balance. Respondents with mercury levels >2ppm, risk to have body balance disorders 6 times compared to respondents with mercury levels in hair ≤2ppm after controlled by age variable. For further research it is suggested to conduct airborne measurements around the ASGM location as a reference for mercury exposure which is enter through the inhalation pathway.
