“…Due to the southwest monsoon in Southeast Asia during this period, smoke particles and gases originating from peatland fires in Sumatra Island travel to the west coast of Peninsular Malaysia, resulting in frequent transboundary haze pollution (Mahmud, 2009). Transboundary smoke haze causes degradation of local air quality and health impacts in Malaysia (Othman et al, 2014;Sahani et al, 2014).…”

We characterized ambient total suspended particulates (TSP) based on ground-based samplings in Malaysia during nonhaze days and haze ones affected by Indonesian peatland fires. Furthermore, a key indicator of Indonesian peatland fire was determined based on chemical characterization of TSP in Malaysia. TSP samples were chemically analyzed to determine organic carbon (OC), elemental carbon (EC), inorganic ions, and biomarkers (solvent-extractable organic compounds derived from biomass burning). Regarding OC and EC, concentrations of OC1 and OP (pyrolyzed OC) defined by IMPROVE_A protocol increased remarkably during the haze episodes. On the contrary, there were no significant differences in concentrations of OC4, EC, and EC fractions between the haze and non-haze samples. Regarding inorganic ions, sulfate and ammonium concentrations increased in strong haze days, however, it is difficult to use these compounds as indicators for Indonesian peatland fires in light haze days due to the partial overlapping of the variation ranges of sulfate and ammonium concentrations in non-haze days. Concentrations of many biomarkers derived from cellulose, hemicellulose, and lignin pyrolysis products were significantly increased during strong haze days but not during light haze days except p-hydroxybenzoic acid. We proposed the OP to OC4 ratio as a potential indicator of transboundary haze pollution from Indonesian peatland fires at the receptor sites even in light haze.

Abstract:Recently, thick haze and poisonous smoke have cloaked the surrounding air in Malaysia due to the uncontrollable and unethical burning of nearby country. This devastating episode of open burning started in the year 1997 in Indonesia which deeply affected most of the ASEAN (association of southeast asian nations) countries especially their neighbour Malaysia and Singapore. The PV (photovoltaic) technology as an alternative means of energy generation experiences such significant energy decrease based on this condition which is due to the shading of sunlight. The 6 h claims of good sunlight has become not more than 2 h and gets worst when the API (air pollution index) struck 200 levels which is at very unhealthy condition. This study embraces some findings from 1 kWp PV generator field data installed in Malaysia reflecting the daily energy decrease operated during this unhealthy weather condition. It is found that, such significant energy decrease with the value of 0.43 W power output per increment of one point API. This value shows such concrete proof of additional factors to be considered in PV modelling in line to support PV technology adaptation in the ASEAN region.

“…It has been shown that haze weather reduces visibility and affects road traffic safety (Hassan and Abdel-Aty, 2011). In addition, inhalation of the substances present in haze often causes adverse effects on the respiratory and circulatory systems of the human population (Nel, 2005), leading to an increased risk of death, high rates of admission to hospital and increased levels of unexpected infant mortality during the weather conditions that contribute to haze (Thach et al, 2010;Ge et al, 2011;Guttikunda and Goel, 2013;Liu et al, 2014;Othman et al, 2014;Gao et al, 2015). The reduction in the number of hours of sunshine caused by haze also affects the growth of crops (Moran et al, 2014).…”

a b s t r a c tStatistical analyses were carried out on the characteristics of haze weather and their relation with air quality and meteorological factors using data recorded by the national air quality and meteorological monitoring network of Chongqing, China in 2013. The results showed that the hourly occurrence rate of haze in Chongqing was 81.3% and that 67.2% of the total number of haze hours was at the level of mild to light haze. Haze was more likely to occur in autumn and winter (67.2% of the total number of hours; occurrence rate 97.5%) and was more likely to occur between 22:00 and 10:00. Haze mainly occurred when the wind speed was <1.2 m s À1 and the relative humidity was >50%. Haze rarely occurred when the wind speed was >3.0 m s À1 and the relative humidity was <30%. There was a positive correlation between temperature and visibility. The occurrence rate was higher with positive variations in the 24-h temperature records. The main factor affecting haze was the level of PM 2.5 pollution. Haze mainly occurred when r(PM 2.5 ) was between 35 and 250 mg m À3 , accounting for 86.4% of the total number of hours of haze. When r(PM 2.5 ) was >75 mg m À3, the occurrence rate of haze was 100.0%. The mean value of r(PM 2.5 )/r(PM 10 ) during the hours of haze was 72.9%, 17.7% higher than that at other times. The number of hours with air pollution accounted for 48.8% of the total number of hours, far less than the occurrence of haze. When the ambient air quality was excellent or good, haze was present in 65.4% of hours. We suggest that there are differences between the assessment of air quality and the definition of haze used in China. The relationship between haze and air quality would be better matched if we used the World Meteorological Organization's definition of haze (visibility < 5.0 km).
