This study examines the effects of IAQ on Sick Building Syndrome (SBS) symptoms across various economic subsectors during the monsoonal seasons in Terengganu, Malaysia. Four locations representing the education (S1), wholesale or retail trade (S2), manufacturing (S3), and services (S4) subsectors were assessed. IAQ was measured using ventilation indicators (carbon dioxide, CO2), chemical parameters (formaldehyde (HCHO), total volatile organic compounds (TVOC), and carbon monoxide (CO)), and physical parameters (temperature, relative humidity, air movement) during the Southwest Monsoon (SWM) and Northeast Monsoon (NEM). The objectives included evaluating IAQ compliance, simulating 3D distributions using Computational Fluid Dynamics (CFD), identifying IAQ factors through Principal Component Analysis (PCA), and developing predictive Generalized Linear Models (GLM). Data included SBS symptom feedback and IAQ metrics, analysed using GLM with SBS syptoms as the dependent variable. Results showed seasonal IAQ variations, with temperatures ranging from 23.50°C to 32.91°C and relative humidity from 57.77% to 90.68%. CO2 levels were higher in enclosed spaces, particularly in manufacturing and retail sectors during the SWM. CFD simulations revealed increased turbulence near ventilation systems, with accuracies of up to 91.90% (SWM, S1) and 91.17% (NEM, S4). PCA identified three main IAQ contributors: physical conditions, chemical exposure, and human activities, accounting for up to 45.58% (NEM, S3), 24.17% (SWM, S3), and 31.42% (SWM, S4) of variance. The GLM demonstrated higher predictive accuracy during the NEM, with an R2 of up to 0.9949. Seasonal variations in IAQ significantly impacted SBS symptoms across different economic sectors in Terengganu, Malaysia. Poor IAQ, driven by physical conditions, chemical exposures, and human activities, was found to be worse during the SWM. The study recommends improving ventilation in enclosed spaces, regularly monitoring IAQ to address seasonal changes, reducing chemical emissions, controlling indoor activities, and enforcing IAQ compliance to create healthier work environments.Item THE DEVELOPMENT OF SPERM CRYOPRESERVATION PROTOCOL FOR PATIN BUAH, Pangasius nasutus (Bleeker, 1863)(Universiti Malaysia Terengganu, 2024-07) WAN NURIZZATI BINTI W IDRISItem CHITOSAN FROM Litopenaeus vannamei SHRIMP SHELLS: A GREEN PRE-TREATMENT BIO-COAGULANT FOR AQUACULTURE WASTEWATER SOLID RECOVERY FOR BIO-FERTILIZER APPLICATION(Universiti Malaysia Terengganu, 2024-01) CHE ENGKU NORAMALINA BINTI CHE ENGKU CHIKItem MICROWAVE PYROLYSIS CONVERSION OF CRAB SHELL WASTE INTO BIOCHAR FOR APPLICATION IN PALM OIL MILL EFFLUENT TREATMENT(Universiti Malaysia Terengganu, 2024-06) YANG YANItem BIODEGRADATION OF MICROPLASTICS BY BIOFLOCCULANT- PRODUCING BACTERIA ISOLATED FROM BIOFLOC BASED SYSTEM(Universiti Malaysia Terengganu, 2024-08) ZUHAYRA NASRIN BINTI AHMAD SHUKRIItem EFFECTS OF TEMPERATURE AND LOW pH ON GROWTH PERFORMANCES AND PHYSIOLOGICAL RESPONSES OF WHITELEG SHRIMP Litopenaeus vannamei(Universiti Malaysia Terengganu, 2024-04) SHIRLY LIM YU LINGItem BIODEGRADABILITY OF MICROPLASTICS BY BIOFLOC-PRODUCING BACTERIA DURING LARVAL REARING OF MUD CRAB, GENUS Scylla(Universiti Malaysia Terengganu, 2024-07) MD.
