    Baseline metals pollution profile of tropical estuaries and coastal waters of the Straits of Malacca
    (Elsevier, 2013) Ley Juen Looi; Ahmad Zaharin Aris; Wan Lutfi Wan Johari; Fatimah Md. Yusoff; Zailina Hashim
    The status report on metal pollution in tropical estuaries and coastal waters is important to understand potential environmental health hazards. Detailed baseline measurements were made on physicochemical parameters (pH, temperature, redox potential, electrical conductivity, salinity, dissolved oxygen, total dissolved solid), major ions and metals concentrations at estuaries and coastal waters along the Straits of Malacca.

    Contamination assessment and potential human health risks of heavy metals in Klang urban soils: a preliminary study
    (Springer, 2014) Sarva Mangala Praveena; Nurul Syazani Yuswir; Ahmad Zaharin Aris; Zailina Hashim
    Urban areas with rapid industrial development have major impacts on environmental soil quality. This study was carried out to determine contamination assessment of heavy metal concentration of urban soil from Klang district (Malaysia). Health risk assessment was used to determine potential health risks (carcinogenic and non-carcinogenic risks) in both adults and children. Moreover, this study was also used to identify the most significant contaminant and exposure pathway with regard to Klang urban soil.

    Health risk assessment of heavy metal in urban surface soil (Klang District, Malaysia)
    (Springer, 2015) Nurul Syazani Yuswir; Sarva Mangala Praveena; Ahmad Zaharin Aris; Sharifah Norkhadijah Syed Ismail; Zailina Hashim
    In this study, a total of 76 urban surface soil samples were collected in the Klang district (Malaysia), and analyzed for total and bioavailable heavy metal concentrations by inductively coupled plasma-optical emission spectrometry.

    Hubungan pencemaran partikel terampai (PM10) dengan pesakit asma
    (Universiti Pertanian Malaysia Press, 1996) Zailina Hashim; Juliana Jalaludin; Azman Zainal Abidin; Azizi Haji Omar
    Satu kajian terhadap 30 orang pesakit asma yang terdiri dari kanak-kanak telah dilakukan di Kuala Lumpur. Objektif kajian adalah untuk mengenalpasti perkaitan di antara PM10 dan serangan asma yang dialami oleh pesakit. Kajian berbentuk epidemiologi prospektif telah dilakukan dari 1 September 1994 sehinggga 31 Disember 1994. Pesakit asma telah dipilih dari Unit Pediatrik Hospital Besar Kuala Lumpur.

    Lead and cadmium content of total suspended particulates in the atmosphere over the Klang Valley
    (Universiti Pertanian Malaysia Press, 1995) Jamal Hisham Hashim; Zailina Hashim
    Five sites (urban, suburban, new township, industrial, and rural) were selected and sampled for total suspended particulates (TSP) using high-volume samplers. The TSP were then analysed for their lead and cadmium content in 3 extraction fractions. While the most polluted sites for atmospheric lead andcadmium were different, namely the BBP (Pudu Fire Station) urban and UPM (Universiti Pertanian Malaysia) suburban sites, respectively, the least polluted site was the same for both metals, namely the KSM (Sungai Merab Village) rural site.Comparisons of the temporal distribution patterns of TSP, lead and cadmium indicate that variation in TSP concentrations does not seem to influence variations in lead and cadmium concentrations. Analysis of fractionation patterns suggests that the BBP urban site has slightly higher percentages of anthropogenic lead and cadmium from fresh sources than the other sites.

    Mercury contamination in the estuaries and coastal sediments of the Strait of Malacca
    (Springer, 2015) Ley Juen Looi; Ahmad Zaharin Aris; Fatimah Md. Yusoff; Zailina Hashim
    Sediment is a great indicator for assessing coastal mercury contamination. This work profiled the magnitude of mercury pollution in the tropical estuaries and coastal sediments of the Strait of Malacca. Mercury was extracted through the ultrasound-assisted mercury extraction method and analyzed using the flow injection mercury system.

    Risk of dietary mercury exposure via marine fish ingestion: Assessment among potential mothers in Malaysia
    (Springer, 2019) Pravina Jeevanaraj; Zailina Hashim; Saliza Mohd Elias; Ahmad Zaharin Aris
    Mercury (Hg) is a very toxic heavy metal that can permanently damage the brain of a developing fetus, particularly through maternal fish consumption. Being the highest seafood consumers in South East Asia, Malaysian mothers are probably at Hg exposure risk. Hence, this study was undertaken to assess the health risk associated with Hg from marine fish consumption and the types of fish that could possibly increase the exposure dose.

    School indoor air pollutants: In relation to allergy and respiratory symptoms among school children in urban areas
    (University of Tehran, 2022) Zailina Hashim; Nur Shahira Mohamad Fadzil; Siti Raihan Mohd Fuad; Shamsul Bahari Shamsudin; Khairul Nizam Mohd Isa; Tan Tek Song; Jony Sieman; Saliza Mohd Elias; Jamal Hisham Hashim
    Indoor air pollutants affect children's health and previous research mostly focuses on respiratory and allergic diseases. However, little is known about the risks among school children in East Malaysia. Therefore, we studied associations between school children's respiratory and allergic symptoms and indoor air pollutants in schools in Sabah, Malaysia. We randomly enrolled 332 school children (14 years old) from 24 classrooms in 6 secondary schools in Kota Kinabalu, Sabah. Information on personal characteristics, respiratory and allergic symptoms were gathered by using a standard questionnaire. The skin prick test was used to characterize the atopy. In each classroom, the indoor concentrations of particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), formaldehyde, total volatile organic compounds (TVOC), carbon dioxide (CO2) temperature and relative humidity were monitored.

    Volatile organic compounds (VOC), formaldehyde and nitrogen dioxide (NO2) in schools in Johor Bahru, Malaysia: Associations with rhinitis, ocular, throat and dermal symptoms, headache and fatigue
    (Elsevier, 2017) Dan Norbäck; Jamal Hisham Hashim; Zailina Hashim; Faridah Ali
    This paper studied associations between volatile organic compounds (VOC), formaldehyde, nitrogen dioxide (NO2) and carbon dioxide (CO2) in schools in Malaysia and rhinitis, ocular, nasal and dermal symptoms, headache and fatigue among students. Pupils from eight randomly selected junior high schools in Johor Bahru, Malaysia (N = 462), participated (96%). VOC, formaldehyde and NO2 were measured by diffusion sampling (one week) and VOC also by pumped air sampling during class. Associations were calculated by multi-level logistic regression adjusting for personal factors, the home environment and microbial compounds in the school dust.
