“…During this period, almost 50 % of the southern ASEAN region is dominated with fire hot spots especially in the provinces of Riau, central and southern Kalimantan, and other parts of Borneo and Sumatra (Juneng et al 2009;NEA 2009NEA , 2010. The southwesterly winds which usually prevail in June are suspected to be responsible for transporting the haze containing biogenic pollutants, affecting the atmospheric conditions of neighboring countries (Juneng et al 2009;NEA 2009NEA , 2010Soleiman et al 2003).…”

Concentration activities of (210)Pb and (210)Po in the PM10 were determined to discuss their distribution and chemical behavior in relation to meteorological parameters especially in air mass transport during monsoon events. Marine aerosol samples were collected between January 2009 and December 2010 at the coastal region of Mersing, which is located in the southern South China Sea and is about 160 km northeast of Johor Bahru, as part of the atmosphere-ocean interaction program in Malaysia. About 47 PM10 samples were collected using the Sierra-Andersen model 1200 PM10 sampler over a 2-year sampling campaign between January 2009 and December 2010. Samples were processed using acid digestion sequential extraction techniques to analyze various fractions such as Fe and Mn oxides, organic matter, and residual fractions. While, (210)Pb and (210)Po activities were measured with the Gross Alpha/Beta Counting System model XLB-5 Tennelec® Series 5 and the Alpha Spectrometry (model Alpha Analyst Spectroscopy system with a silicon-surface barrier detector), respectively. The distribution activities of (210)Pb and (210)Po in the PM10 samples were varied from 162 to 881 μBq/m(3) with mean value of 347 ± 170 μBq/m(3) and from 85 to 1009 μBq/m(3) with mean value of 318 ± 202 μBq/m(3), respectively. The analysis showed that (210)Po activity in our samples lies in a border and higher range than global distribution values due to contributions from external sources injected to the atmosphere. The speciation of (210)Pb and (210)Po in marine aerosol corresponds to transboundary haze; e.g., biomass burning especially forest fires and long-range air mass transport of terrestrial dust has enriched concentrations of particle mass in the local atmosphere. The monsoon seems to play an important role in transporting terrestrial dust from Indo-China and northern Asia especially during the northeast monsoon, as well as biogenic pollutants originating from Sumatra and the southern ASEAN region during southwest monsoon events.

“…Beberapa kejadian letusan gunung berapi telah menyebabkan fenomena jerebu berlaku. Antaranya ialah Gunung Pinatubo di Filipina (Soleiman et al 2003) dan Gunung Berapi Kilauea di Kepulauan Hawai'i (Tam et al 2016). Letusan gunung berapi berkenaan telah membebaskan sulfur dioksida (SO 2 ) yang seterusnya berinteraksi dengan wap air untuk menghasilkan jerebu berasid dikenali sebagai 'vog'.…”

“…Seterusnya, pertambahan kuantiti kenderaan bermotor telah menyumbang kepada berlakunya pencemaran udara terutama di kawasan bandar dengan peningkatan bahan pelepasan daripada kenderaan bermotor. Kenderaan yang menggunakan tenaga fosil seperti minyak petrol dan diesel mengeluarkan asap yang menyebabkan terjadinya pembebasan gas seperti karbon monoksida (CO) dan sulfur dioksida (SO 2 ) (Mahmud & Ab Llah 2010;Soleiman et al 2003). Gas pencemar berkenaan merupakan bahan terampai yang memenuhi ruang udara dan terperangkap dalam lapisan bumi kerana tidak dapat dibebaskan ke atmosfera.…”

Jerebu merupakan fenomena pencemaran udara yang memberi impak negatif kepada kesihatan dan kegiatan sosial masyarakat serta negara. Isu jerebu dibincangkan dalam al-Quran iaitu sura al-Dukhan secara menyeluruh. Kertas ini bertujuan menganalisis perbahasan berkaitan masalah jerebu yang disebutkan oleh al-Quran dan tafsiran para sarjana Islam dalam konteks dan sudut pandang Islam. Kertas ini turut membincangkan punca dan kesan berlakunya masalah jerebu daripada perspektif sains. Kajian ini menggunakan kaedah kualitatif iaitu dengan merujuk kepada kaedah transdisiplin daripada perspektif Quran dan sains. Keputusan kajian mendapati terdapat tafsiran para sarjana Islam yang mentafsirkan surah al-Dukhan dan fenomena jerebu yang berlaku pada zaman Rasullullah SAW. Ia merupakan azab dan seksaan kepada kaum Musyrikin disebabkan oleh perbuatan mereka yang enggan menerima ajaran Islam. Fenomena jerebu merupakan peringatan Allah dan pengajaran kepada umat manusia supaya sentiasa taat kepada perintah dan meninggalkan segala larangan-Nya di samping bersama-sama menjaga keharmonian dan kesejahteraan alam semesta ini. Manakala para saintis pula mendapati fenomena jerebu yang berlaku adalah berpunca daripada asap dan habuk kesan daripada aktiviti antropogen dan semula jadi serta kesannya terhadap kesihatan tubuh badan manusia yang mengakibatkan hidung berair, masalah kulit, mata terasa pedih dan berair, batuk, sakit kerongkong, kesukaran untuk bernafas dan kesakitan di bahagian dada.

“…Although air pollutants are very important to the formation of haze in the atmosphere, this formation requires commensurate weather conditions. In urban areas, the occurrence of hazy conditions is indicative of air quality (Soleiman et al 2003, Wu et al 2007. As an ephemeral event that takes place over an extensive area, haze is ideally studied by means of remote sensing, especially from fine-temporal resolution meteorological satellite images such as those from the advanced very high resolution radiometer (AVHRR) or moderate resolution imaging spectroradiometer (MODIS).…”

Haze is an undesirable meteorological and environmental phenomenon that can cause enormous harm to the environment, people's lives and health, and economic activities. This study focuses on Nanjing, Yangzhou and Suzhou in the lower reaches of the Yangtze River valley, China, which have suffered from the adverse effects of hazy weather in recent years. The spectral influence of haze on surface features was determined through analysis of the spectral variations of surface covers between hazy and haze-free days. On the basis of the established relationship, a new index called the normalized difference haze index (NDHI) was derived using moderate resolution imaging spectroradiometer (MODIS) data from winter 2008-2009. Correlation analysis of the derived NDHI with in situ observed PM 10 (particulate matter with diameter <10 µm) data reveals that NDHI over water bodies has a coefficient of 0.74, 0.57 and 0.67 with PM 10 for Nanjing, Yangzhou and Suzhou, respectively. It is concluded that NDHI is a reliable indicator of air pollution. It can be used as a new method of effectively monitoring air pollution from remotely sensed data.
