Guangxi Nandan county is a typical karst geological area, groundwater is rich, rich Tibetan non-ferrous metals. In order to study the risk of groundwater pollution on human health in mining area of Nandan County, base on the investigation and monitoring, The results of groundwater environment risk assessment of mine area of Nandan County show that water environmental health risk of No.5 belong to the minimum level, No.1, No. 2, No.3 and No.7 of four monitoring points is low risk,No.4 and No.6 for medium risk, No.8 as high risk.The health risk average value caused by toxic substances to individual person per year is 4.76×10-5a-1, which is less than the maximum acceptable level5×10-5a-1recommended by ICRP. The groundwater environmental health risks, mainly comes from chemical carcinogens arsenic (As), accounted for the average health risk (Rt) 99.998%,non carcinogenic health risk accounted for only 0.002%, almost negligible, therefore,stricter governing of chemical carcinogens is an effective way to reduce the health risk of groundwater pollution in mining area of Nandan County.

In Indonesia it is estimated that there are around 250,000 artisanal and small-scale gold mining (ASGM) and generally use mercury for amalgamation process and then release it to the environment during gold refining process. This study aims to analyze mercury levels in the environment around ASGM in Lebaksitu Sub-District, Lebak District, Banten Province and identify hazardous exposure that may occur. The study design used was descriptive observational with Environmental Health Risk Assessment (EHRA) method. Environmental data taken include water and food samples. Social-demographic and dietary interviews were conducted. The study population was 72 residents of Lebaksitu Sub-District obtained through sample size formula and selected by simple random sampling. The study was conducted from April to May 2017. Exposure assessment is an important part of risk assessment. Exposure is a process that causes contact with environmental hazards such as risk agents, as a bridge connecting 'hazards' to 'risks'. Exposure analysis needs to consider all routes (inhalation, ingestion, absorption) and media (air, water, soil, food, drinking water) so that the total intake can be calculated. Exposure route analysis usually generate a critical pathway, the dominant exposure path. This pathway concerns which environmental media is the vehicle of risk agent and how it enters the body. Once a critical pathway is found, other possibility pathways contribution may be small and can be ignored. Mercury is a toxic pollutant that bioaccumulated and biomagnetic continuously through the food chain. The levels of mercury at the research sites on rice, fish, and vegetables have average of 0.027 mg/kg; 0.283 mg/kg; and 0.410 mg/kg. The calculation of risk assessment obtained value of risk quotient (RQ) of 3.79 (RQ>1). The results of this calculation of risk assessment showed that mercury content in samples of rice, fish, and vegetables originating from Lebaksitu Sub-District potentially cause a health risk for the community surrounding the gold mining area who consume it.

Sampah yang tidak dikelola merupakan sumber pencemar lingkungan dan tempat berkembangnya berbagai macam bakteri, pathogen, parasit dan sarang berbagai vektor.Pencemaran lingkungan yang disebabkan oleh sampah yang terjadi di kota Meulaboh Kabupaten Aceh Barat dapat terlihat dengan banyaknya ditemukan sampah yang dibuang tidak pada tempatnya sehingga menimbulkan kesan kumuh dan kotor dan menghasilkan bau yang tidak sedap.Penelitian Environmental Health Risk Assessment (EHRA) tahun 2012 menunjukkan bahwa sekitar 78,1% masyarakat Kabupaten Aceh Barat belum menerima layanan pengangkutan sampah, hal ini menggambarkan bahwa manajemen sampah kota di Kabupaten Aceh Barat belum berjalan dengan baik. Tujuan Penelitian ini adalah untukmengidentifikasi kesesuaian pengelolaan sampah dengan peraturan dan perundang-undangan tentang manejemansampah.Jenis penelitian kualitatif dengan rancangan studi kasus di kota Meulaboh.Subjek Penelitian terdiri dari 4 orang penjabat eksekutif pemerintah Kabupataen Aceh Barat dan 7 orang tokoh masyarakat.Data dikumpulkan melalui observasi dan wawancara mendalam. Hasil penelitian menunjukkan bahwa masih terbatasnya anggaran dalam manajemansampah.Umumnya masyarakat masih kurang terlibat dalam pengelolaan sampah dan cenderung melimpahkan tanggung jawab pengelolaan sampah kepada pemerintah. Kesimpulan Pengelolaan sampah di Kabupaten Aceh Barat belum sepenuhnya sesuai dengan peraturan dan perundang-undangan yang berlaku.Perlu meningkatkan anggaran untuk pengelolaan sampah di Kabupaten Aceh Barat.

Air pollutant gas that has a real impact on the respiratory system is NO2 and SO2. Kalianak Surabaya is one of the areas with high traffic density more than 1.500 vehicles every hour. The most affected communities are the people living along the Kalianak highway. This study aims to analyze the ambient air (NO2 and SO2) in Kalianak and the risk of respiratory distress in the surrounding community. This research is descriptive, with cross sectional approach. The sample of this research is 19 respondents was done by purposive sampling. Spirometers were used to determine the status of lung function. The variables studied were age, length of stay, smoking habit, and Body Mass Index. The collected data were analized with environmental health risk assessment. Environmental Health Risk Assessment showed that the people living in this area unsafe with concentration of NO2 as measured. The results showed that more than 50% of respondents have respiratory problems (68,4%) with the mayority of respondenst aged 46-55 years old (31,6%), leght of stay >20 years (47,4%), non smokers (47,4%), and normal Body Mass Index (36,8%). The conclusion from this research is ambient air quality (NO2 and SO2) in Kalianak Surabaya still meet the quality standard, and the RQ>1 for NO2, it means that the risk level is unsafe. It is recommended that there is an efforts to control air pollution caused by motor vehicle activity by planting planst that can reduce ambient air pollutants.

Nowadays NO2 ambient level has been increasing in year to year. Pollutant level which has over level from the threshold limit will give some of bad effects to environment and human health. The aim of this study was to measure the environmental health risk assessment of NO2 ambient level and toll collectors officer ‘s health complaints at Toll gate of Dupak 1, Surabaya. This was descriptive study with cross sectional design. Interview was done to 17 respondents who met the conclusion criteria to know respondent’s health complaints. Independent variables were NO2 level, sex, age, weight, length of work in a day and work period. Where as dependent variabel was toll collectors officer’s of Toll gate of Dupak 1 Surabaya health complaints, such as: headache, eyes irritation, red eyes, hard to breath and cough. Result shown that respondent with 62 weight average were not safe work in Toll gate of Dupak 1 if the air velocity was 0.83 m3/ hour, in 8 hour/day, average of time in 350 days/year for next 30 years if NO2 level had maximal concentration 0.1183 ppm (RQ > 1). The majority of health complaints were cough 82.3%, red eyes 70.5%, eyes irritation 64.7%, headache 53%, and hard to breath 47%. However risk quotient of NO2 exposure was not safe for respondent with pollutants level appropriate to the measurement result and should have preventive action like as consume vitamin C and E and use N95 and regulations for using masker and not smoking while work have to applied strictly.
