H₂S Emissions within Vicinity of Swine Farming Area in Nibong Tebal, Pulau Pinang, Malaysia

Abstract

Animal farming industries is important in Malaysia because its contribution to the economy. The production causes all the major environmental negative impact such as water pollution from waste water and malodours emanating from farms. The current methods of disposing of manures were no longer adequate or suitable for the new, large and intensive animal farming. Inappropriate technologies, poor maintenance and inadequate dimensions and design of the treatment systems in addition to inappropriate production method are causing serious environmental problems especially odorous emissions. Present of Hydrogen Sulphide (H2S) in the air contribute to the odour pollution. Static monitoring has been done and maximum concentration of H2S is 220.6 ppb. Temperature and relative humidity fluctuations were seem to have influence on concentration of H2S. Linear regression analysis was shown that relative humidity has higher influence on correlation gaseous pollution compared to temperature. Correlation coefficient for H2S and relative humidity was in range 0.675 to 0.881 in the morning and 0.417 to 0.729 in the evening, which are in range of strong correlations.

Prevalence and Haplotypes of Toxoplasma gondii in Native Village Chickens and Pigs in Peninsular Malaysia

“…The most common management system practised in pig farms is the intensive farm system, categorized into an open-house and close-house system [ 22 ]. An open-house farm is characterized by an open-sided house with natural ventilation, not properly gated, stray animals may access the pens, and the pigs are kept in confined pens with adequate shelter on a concrete or hard floor with sufficient feeding and watering facilities.…”
