Penelitian ini bertujuan untuk menguji model AERMOD dalam memprediksi sebaran PM10 di udara ambien kawasan PT Semen Padang. Lokasi penelitian sebanyak 32 titik berdasarkan 8 arah mata angin dengan jarak 0,5 km, 1 km, 1,5 km dan 2 km dari PT Semen Padang. Pengukuran PM10 menggunakan EPAM 5000 Real Time Particulate Air Monitor dilanjutkan pemetaan dengan software Surfer 11. Waktu pengukuran dibagi menjadi 4 shift, yaitu shift 1 (00.00 – 05.59 WIB), shift 2 (06.00 – 11.59 WIB), shift 3 (12.00 – 17.59 WIB) dan shift 4 (18.00 – 23.59 WIB). Pengambilan data meteorologi (temperatur udara, tekanan udara, kelembapan, kecepatan angin dan arah angin) menggunakan alat Meteorological Station PCE-FWS-20 untuk input data pada AERMET, dilanjutkan prediksi sebaran PM10 menggunakan software AERMOD View 8.9.0. Hasil penelitian menunjukkan konsentrasi PM10 dengan EPAM 5000 berkisar antara 21,0 – 79,0 µg/m3 dengan rata-rata 24 jam sebesar 41,7 µg/m3. Konsentrasi PM10 dengan AERMOD berkisar antara 3,5 sampai 68,0 µg/m3 dengan rata-rata 24 jam sebesar 10,6 µg/m3. Jika dibandingkan dengan baku mutu untuk Peraturan Pemerintah No. 22 Tahun 2021 tentang Penyelenggaraan Perlindungan dan Pengelolaan Lingkungan Hidup, lokasi 11 dengan koordinat S 0°56'52.46" dan E 100°27'41.88"  pada  jarak 1 km kawasan Barat PT Semen Padang tidak memenuhi baku mutu. Model mendekati ideal atau dikatakan sempurna yaitu lokasi arah Timur dan Timur Laut karena elevasi yang lebih tinggi dari sumber emisi dan merupakan arah angin dominan pada siang hari.ABSTRACTThis study aims to test the AERMOD model in predicting the distribution of PM10 in the ambient air of the PT Semen Padang area. The research locations were 32 points based on eight cardinal directions with a radius of 0.5 km, 1 km, 1.5 km, and 2 km from PT Semen Padang. PM10 measurement using EPAM 5000 Real-Time Particulate Air Monitor followed by mapping with Surfer 11 software. The measurement time is divided into four shifts, namely shift 1 (00.00 – 05.59 WIB), shift 2 (06.00 – 11.59 WIB), shift 3 (12.00 – 17.59 WIB), and shift 4 (18.00 – 23.59 WIB). Meteorological data retrieval (air temperature, air pressure, humidity, wind speed and wind direction) using the Meteorological Station PCE-FWS-20 for data input to AERMET, followed by prediction of PM10 distribution using AERMOD View 8.9.0 software. The results showed that the concentration of PM10 with EPAM 5000 ranged from 21.0 – 79.0 g/m3 with a 24-hour average of 41.7 g/m3. The concentration of PM10 with AERMOD ranged from 3.5 - 68.0 g/m3 with a 24-hour average of 10.6 g/m3. When compared with the quality standard for Government Regulation no. 22 of 2021 concerning the Implementation of Environmental Protection and Management, location 11 with coordinates S 0°56'52.46" and E 100°27'41.88" at a distance of 1 km west of PT Semen Padang does not meet the quality standards. The model is close to ideal or is said to be perfect, namely the location of the East and Northeast directions because of the higher elevation of the emission source and the dominant wind direction during the day.

The lack of clean water distribution by local water service (PDAM) of Palangka Raya city is the major reason for people around the final processing site/landfill (Tempat Pemrosesan Akhir) at Km 14 to use groundwater for their daily life. The landfill may cause pollution over groundwater known as leachate, which commonly unnoticed by its users. This study aims at assessing the quality of groundwater in that area. The groundwater was taken at different distances from the site in three rainless-days. The physical, chemical and biology parameters of groundwater are observed in the field (in situ) and analyzed in the laboratory, refers to water quality standard of Class I, according to Government Regulation No. 82 of 2001 and Minister of Health Regulation No. 32 of 2017. Public opinion on that issue is cached through interview. The results showed that the groundwater around the landfill in three rainless-days was harmless to be consumed as drinking water, and did not exceed the water quality standards stipulated by government in term of odorless, tasteless, and colorless. Some indicators also show that the groundwater meets the specified quality standards, i.e. TDS (17-68.14 mg/L), DHL (17,15-69.39 ?s), turbidity (0.11-2.50 mg/L), iron (0.227-0.71 mg/L), manganese (<0.0123-0.02 mg/L), coliform (<1.8-280 MPN/100 ml), while Pb and H2S were not detected. From community side, there are no any health complaints arise as long as they use the water.

Shenzhen is China&rsquo;s top ten clean air city and the cleanest air megacity. Even so, epidemiologic studies have shown ambient air pollution had significant adverse impacts on human health in this less polluted city. In this study, the concentrations of six criteria air pollutants (PM2.5, PM10, O3, NO2, SO2, and CO) from 2014 to 2017 were analyzed and compared to thresholds of both national and international air quality standards. The results showed concentrations of all air pollutants were below target values of current national air quality standard, but levels of particulate matter (PM) and O3 were still much higher than the recommended levels by the World Health Organization. Within national air quality standards, the number of over-limit days was rare with few variations between highly polluted and low pollution areas. The air quality improvement was slowing down recently. Our results suggest annual and daily thresholds for PM are too loose for air quality improvement in Shenzhen. Hence, we call for evaluation and establishment of tougher air quality standard.

Meteorological Observations

Abstract Some of the first systematic meteorological observations in Africa were made by two women in Equatorial Guinea in 1875. Sisters Isabel and Juliana Urquiola, together with Manuel Iradier, Isabel's husband, built a meteorological observatory on Little Elobey Island (0°59′46″N, 9°32′14″E), off the tiny nation's western coast. From 1 June to 31 December 1875, the sisters took subdaily readings (6, 12, 15, and 18 h past midnight local time) of humidity, temperature, precipitation, and wind direction and speed. To evaluate the quality of these historical observations, the authors have compared them with equivalent modern meteorological data from Cocobeach (the modern meteorological station nearest to Little Elobey). The monthly-mean distributions of maximum and minimum temperature are similar to those of Cocobeach, but minimum temperatures are 2.4°C higher than Cocobeach values. Despite this difference, the observations of the Urquiola sisters were found to be far better and more consistent than other observations of the time. Sadly, the duo never enjoyed an appropriate acknowledgment of their detailed weather measurements, some taken eight times per day, which were some of the first measurements in Equatorial Guinea. Their unappreciated task unfortunately also had a high cost on their health for the rest of their lives, made all the worse for Isabel Urquiola with the loss of a baby.

Hazardous Pollutants

Gas station workers played an important role in providing fuel needs in the community for the transportation system to run smoothly. The higher motor vehicle user, the intensity of refueling also increases. They were at high risk of being exposed to hazardous pollutants from both vehicle emissions and fuel vapors. Although NO2 and SO2 had non-carcinogenic effects, they are still irritants that cause chronic airway disorders. This study aims to analyze the health risks experienced by gas station workers due to NO2 and SO2 exposure in Kendari City. This research was a Quantitative Descriptive study with Environmental Health Risk Method Analysis. The number of samples was 13 operators chosen with total sampling. Measurement of NO2 and SO2 concentrations were carried out in the morning, afternoon and evening. The results of this study showed the highest intake value obtained for NO2 (real-time) was 0.00635 mg/kg/day and SO2 (real-time) 0.00057 mg/kg/day. The highest risk level obtained for NO2 is 0,31775 (RQ<1) and SO2 0,00275 (RQ<1). The conclusion of this study is the quality of ambient air NO2 and SO2 at SPBU 74,931.10 is still safe and meets the National Ambient Air Quality Standard in a short time. But otherwise, it will be at high risk for health if the operator was exposed for a long time and continuously. It should be made an effort to monitor and control air pollution. As well as the policy of using Personal Protective Equipment to minimizing exposure to ambient pollutants.
