This study deals with the distribution of dichlorodiphenyltrichloroethanes (DDTs) and hexachlorocyclohexanes (HCHs) in urban soils, their possible sources and probabilistic human and environmental health risk. The average concentrations of total HCHs and total DDTs in the soils were in the range of 0.56-8.52 mg kg<sup>&ndash;1</sup> and 0.54-37.42 mg kg<sup>&ndash;1</sup>, respectively, which were lower than guideline limits. The compositional analysis of HCH isomers reflects contaminations from recent usage. However, isomeric ratios between DDT, DDE and DDD, indicate anaerobic degradation of DDT and contaminations from aged DDT. Human and environmental health risk assessment was carried out by the estimation of lifetime average daily dose (LADD), incremental life time cancer risk (ILCR) and non carcinogenic health hazard quotient (HQ). LADD of total pesticides (HCH and DDT) for human adults and children was ranged between 3.3x10<sup>&ndash;9</sup>-6.6x10<sup>&ndash;8</sup> mg kg<sup>&ndash;1</sup>d<sup>&ndash;1</sup> and 1.7x10<sup>&ndash;8</sup>-3.4x10<sup>&ndash;7</sup> mg kg<sup>&ndash;1</sup> d<sup>&ndash;1</sup>, respectively. The cumulative ILCR for adults and children was ranged from 5.1x10<sup>&ndash;9</sup> to 4.6x10<sup>&ndash;8</sup> and 2.6x10<sup>&ndash;8</sup> to 2.4x10<sup>&ndash;7</sup>, respectively. The HQ was ranged between 1.8x10<sup>&ndash;6</sup>- 1.4x10<sup>&ndash;4</sup> and 9.5x10<sup>&ndash;6</sup>-7.2x10<sup>&ndash;4</sup>, respectively for adults and children. These estimated ILCR and HQ were within the safe acceptable limits, indicating negligible risk to the residents of the study area.

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.

<em>Background</em>. Polychlorinated biphenyls (PCBs) have never been produced in India, but were used in industrial applications. PCBs have been detected in environmental samples since 1966, and their sources in soils come from depositions of industrial applications, incinerators and biomass combustions. PCBs adsorb to soil particles and persist for long time due to their properties. Their close proximity may also lead to human exposure through ingestion, inhalation, dermal contact, and may exert neurotoxic, mutagenic and carcinogenic health effects. <br /><em>Design and Methods</em>. Residential soil from Korba, India, was extracted using pressurized liquid extraction procedure, cleaned on modified silica and quantified for PCBs. Soil ingestion was considered as the main exposure pathways of life-long intake of PCBs. Human health risk in terms of life time average daily dose, incremental lifetime cancer risk (ILCR) and non-cancer hazard quotient (HQ) were estimated using established guidelines. <br /><em>Results</em>. The estimated average ILCR from non dioxin like PCBs for human adults and children was 3.1×10−8 and 1.1×10−7, respectively. ILCR from dioxin like PCBs for human adults and children was 3.1×10−6 and 1.1×10−5, respectively. The HQ for PCBs was 6.3×10−4 and 2.2×10−3, respectively for human adults and children. Study observed that ILCR from non dioxin like PCBs was lower than acceptable guideline range of 10−6-10−4, and ILCR from dioxin like PCBs was within the limit. HQ was lower than safe limit of 1. <br /><em>Conclusions</em>. Study concluded that human population residing in Korba had low health risk due to PCBs in residential soils.

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.
